    There is a lot of interest in fueling on the N54 platform. This is necessitated of course by limitations of the direct fuel injection system. Many guys are now running supplemental port fuel injection in addition to upgrades to the direct fuel injection system. VTT (Vargas Turbocharger Technologies) is upgrading their project car's fuel system. They are not selling these upgrades but it certainly is fueling (haha, get it?) a big discussion on the BimmerBoost forums regarding the topic. The car is running the VTT 'Shotgun' direct injection upgrade along with a port fuel injection system. Further details on how VTT is upgrading the fuel system from Tony@VargasTurboTech are below. Decided to get the car ready for big power once we get the built motor back, and throw the stage 3 back on it. Bought the Radium triple surge tank, 3 Walbro 450's, and was able to tuck it into the trunk cubby for a completely stealth system that can easily support 1000-1200WHP on 100% E85. I have each pump wired to a relay, one pump is triggered by the factory signal, second pump comes in at 10 psi, 3rd at 20 psi. Took quite a bit of work, but to me this is the cleanest way, everything in the tank stays nice and stock except one return fitting, and the rest is hidden from view, and extremely quiet. Couldn't be happier with the set up, and honestly it cost me around $1200 to do it not counting my labor, that's not bad considering what other kits cost. If anyone has any specific questions on how its set up, I would be happy to answer them. Basically this is the break down. Stock pump feeds stock filter, which feeds surge tank, 3 pumps into a 3 to 1 Y fitting. Three -6 in one -8 out. -8 all the way to the FPR, then -8 out of the FPR -8 to dual -6 Y fitting, one -6 up to shotgun, one -6 to PI. -6 return from FPR to surge tank, -6 from surge tank to driver bucket. Anyone trying to make real power on these motors is going to need a fuel system like this, until a real double or triple drop in option is available

    Ouch. An impressive pull here by BimmerBoost member @///Monst3r's manual E92 335i. His car is upgraded with a JP Works single turbo N54 kit and uses a Precision 6466 turbocharger. Dyno numbers and pictures are one thing but seeing the kit in action is another. You see it in action here against an ESS-Tuning supercharged E92 M3. We do not know if this is a VT2-625 setup or what pulley is being used. What we do know is that ESS is cited often on forums as a strong performance option for the E92 M3 yet at BimmerBoost we see race after race of their cars getting cleaned up. What makes this run impressive is you visibly see the E92 335i lose traction from the M3 camera car's perspective. The M3 gets a lead yet the 335i regains traction and quickly closes the gap and pulls. That is a massive power disparity right there. Excuse the poor video quality at night time but you can still easily see what happens.

    F80 M3 and F82 M4 owners are already pushing their motors hard despite tuning on the platform being at a fairly early stage. More and more 700+ wheel horsepower examples thanks to turbo upgrades are hitting the roads and some guys have already hit some internal hardware limits. You can read the various forums and see that rods have given way and some guys have blown motors but is that due to the internals not being able to take it or the tuning? The answer is likely somewhere in the middle. Much like in the N54 world tuning will evolve and engines tuned early on let go at far less power than people are making on the stock motor these days. The S55 will evolve and make considerable power on the stock internals but for those who want peace of mind (and a bit of tuning leeway) upgraded internals are a must. TPG Tuning is putting together a built S55 with upgraded rods and pistons. There is another East Coast tuner that apparently ordered some of these same internals so people are pushing these cars hard already. We look forward to seeing the finished built S55 product,

    We like to see dyno results supporting a product. Maximum PSI provides said dynos for their S55 intake product here. However, when the data source is the party selling the part it is necessary to question their claims as the larger the gains appear the more it will drum up attention and sales. Some tuners abuse this aspect hand picking runs that portray their product in the best light and never post any dyno runs or data that does not. We are not saying that is happening here but some tempered expectations may be necessary. Is the S55 intake system employed from the factory on the F80 M3 and F82 M4 a major point of restriction? Perhaps but not to the degree in stock form that we see it portrayed here. The restriction will increasingly become a bottleneck as more air is moved such as in a tuned example. The F80 M3 test car is a tuned example. Let's get some of the details from Maximum PSI themselves: Maximum PSI on the BimmerBoost forums states they removed the claim of a 50 whp gain due to it potentially being misleading although as you can see from the direct quote the claim remains. Let's look at a graph comparing the OEM airboxes (blue line) to the Maximum PSI design (red): You will see gains through the curve but the meat of the gain is above 6000 rpm. So, for top end horsepower, the factory airbox is somewhat restrictive. With the S55 torque curve dropping hard gaining power up top is certainly appreciated and addresses a weakness of the stock curve. 50 rwhp although a peak gain on one run is not a realistic representation. However, what one sees will depend on supporting modifications, a tune, etc. There are definitely major gains to be had up top in the rev range and it will be interesting to see how other tuners address the S55 intake system. Keep in mind Maximum PSI changes the location of the intake as well. Here are their thoughts:

    20 roll (m3 camera car) 26# pump+meth Got some crazy spinning even with 295 r888's but 295/30/19. Need more side wall so planing on running a 275/40-45/16 m/t setup. Feathered the throttle a little and got back in it, reeled him in easy and pulled hard from there.

    BimmerBoost member @cryptocar has a 2013 F30 335xi. These models are equipped with the N55 turbo motor. A fairly well known problem is the BMW oem charge pipe fails. It happens with stock boost and on stock cars and not just on modified examples. @cryptocar's car was modded with the Dinan Stage I tune. A weak tune, as we already demonstrated in an N55 tuning dyno comparison. Due to the Dinan tune on the car and their claim the charge pipe doesn't break unless messed with the dealer refused to warranty the charge pipe which is a $450 part and dealers charge up to $500 to replace it. @cryptocar could not get the dealer to warranty the part and Dinan was not any help. Here's a quick overview: Frustrating right? Dealer won't warranty the part as they can say the car is modded and Dinan refuses to help as they say this is a common failure on the N55. Let's get some more details: So he is out the money on the charge pipe and labor which he should not be. The illusion of the Dinan warranty safety net with BMW is exactly that, an illusion. It is a strong marketing ploy and that is primarily how they use it. The first thing BMW, Dinan, and basically any of these companies these days will do is try to get out of honoring a warranty. They have people and departments dedicated to this task. Ask yourself this question. What is the point of paying more for a Dinan product that is supposedly safer if Dinan will hang you out to dry blaming BMW and BMW will hang you out to dry for running the Dinan product? Even if it is a BMW dealer that sells Dinan parts? You would be in the same position with any other part from anyone else, wouldn't you? Ultimately, what wins out is not honoring if the warranty if they can get away with it. They got away with it.

    Many of you are wondering why someone would ditch the S62 5.0 liter V8 under the hood of the E39 M5 for a smaller BMW inline-6 motor. Well, these results make a strong argument for such a swap. This E39 M5 belongs to BimmerBoost member @Omni. You can read all about his decision to do the swap in a past article. Even at lower power levels than the car runs currently it was a beast. @Omni beat up on a tuned Cadillac CTS-V Wagon as well as a tuned F13 M6 Gran Coupe. With the car now making over 800 to the wheels it is safe to say he can take on even more stout competition. He is running a Precision 6266 turbocharger at 35 psi of boost. 100% methanol is injected in a direct port setup. A water and methanol blend is utilized as well before the compressor. Tuning is by @NickG of Technique Tuning and done on the stock DME no less. The result? 813 horsepower and 819 lb-ft of torque at the wheels which works out to comfortably over 900 at the crank. However you feel 800+ horsepower at the wheels is serious power and this may be the world's most powerful E39 at this point. Simply incredible results and props to @Omni for continuing to push the boundaries.

    Russian BenzBoost member @Vasily1 has a variety of nice boosted toys. One of them is this W212 Mercedes-AMG E63 built by GAD Motors. They call it 'Stage VIP' which is essentially 'Stage Fat Wallet' as it is pretty much a custom build tailored to what @Vasily1 wants. On an intermediate tune (in other words there is more in it) the car puts down 1115 horsepower and 1018 lb-ft of torque at the crank. This makes it difficult to compare to Dynojet outputs at the wheels or other dynos. There is no doubt the car is absurdly fast. We have not seen anything on this setup yet due to the Russian winter which is certainly understandable. When things get warmer he will go to events and try it out against some stout competition. He trapped 142.5 in the 1/4 mile although this was not measured on an NHRA sanctioned dragstrip. You can get an idea as to the performance capability in the video below where the E63 runs a Huracan. Despite the Huracan getting a huge lead the GAD E63 runs it down and pulls past. The 1/4 mile trap speed in the video is 139 miles per hour. The E63 also runs a PP-Performance tuned F12 M6. It makes easy work of it running a 10.58 @ 138.76. The M6 only manages a 12.19 @ 126.8 in comparison. It will be interesting to see what the car does at the next round of Moscow Unlimited events and @Vasily1 has talked about getting it out to a drag strip. GAD Motors certainly is building some potent M157's.

    BMW is the king of high performance SUV's at the moment. It is a very competitive and lucrative segment. Porsche realized how much money could be made a long time ago with the launch of the Cayenne and the Turbo model pretty much set the benchmark for well over a decade. That all changed with the X5M and X6M models. BMW quite simply offers the highest performance SUV's in the marketplace and compared to the Porsche Cayenne Turbo S they are a bargain. Mercedes-AMG is attempting to capitalize on the success of the BMW X6 with the GLE coupe. It is just a restyled GLE much like the X6 is an X5 with slightly different styling. The idea is to stretch the development dollars on the platform to the maximum. Land Rover made a splash with the Range Rover Sport SVR. Considering it set a Nurburgring lap record for SUV's it was clear they meant business. However, the SVR features a supercharged direct injection V8 while the competition is turbocharged. Can it top the turbo Germans? We already knew the F86 X6M would be quite quick based on Car and Driver's F85 X5M test results from August last year. Not to mention the absurdly quick 1/4 mile times we are seeing. MotorTrend fortunately decided to compare the X6M to the Porsche Cayenne Turbo S, Rang Rover Sport SVR, and Mercedes-AMG GLE63 S at the same time and same place which provides quite a bit of context. What it ultimately shows is that BMW is the cream of the crop. The X6M is the quickest in a straight line. It is the fastest with its 114.3 miles per hour of trap speed. Hell, it gets to 100 miles per hour a full second quicker than the next vehicle which is the Mercedes-AMG GLE63 S. BMW has the most muscle, no doubt about it. It is also the quickest around the roadcourse. Here are the laptime results: 4. Range Rover Sport SVR: 1:38.78 3. AMG GLE Coupe S: 1:36.00 2. Porsche Cayenne Turbo S: 1:34.32 1. BMW X6 M: 1:32.46. That is a beatdown. The X6M even edged out an M3 although MotorTrend does not specify which M3 it beat. Even so, that is remarkable as it should be not be beating any M3 around a track. The X6M is clearly doing it mostly with muscle though. The X6M is the fastest, lightest (tied with the Cayenne), best handling, best balanced, and even the cheapest. It is the class benchmark. 4th Place: Mercedes-AMG GLE63 S Coupe Power and comfort and steering for days, but it gets some big things wrong. A blatant photocopy should not be duller than the original. 3rd Place: Porsche Cayenne Turbo S A refresh is coming and not a moment too soon. It’s still great to drive, but all them gray hairs make the old king look, well, old. 2nd Place: Land Rover Range Rover Sport SVR We’re not sure who needs the straitjacket more, the SVR or the team that tuned it. SUVs should (probably) not power oversteer, yet here we are. 1st Place: BMW X6 M An absolute rocket—0-60 mph in 3.7 seconds—and a delight to drive. Giant, deranged smiles can make you overlook shortcomings. It’s the cheapest contender here, too. 2015 BMW X6 M 2015 Land Rover Range Rover Sport SVR 2016 Mercedes-AMG GLE63 S Coupe 4Matic 2016 Porsche Cayenne Turbo S POWERTRAIN/CHASSIS DRIVETRAIN LAYOUT Front-engine, AWD Front-engine, 4WD Front-engine, AWD Front-engine, AWD ENGINE TYPE Twin-turbo 90-deg V-8, alum block/heads Supercharged 90-deg V-8, alum block/heads Twin-turbo 90-deg V-8, alum block/heads Twin-turbo 90-deg V-8, alum block/heads VALVETRAIN DOHC, 4 valves/cyl DOHC, 4 valves/cyl DOHC, 4 valves/cyl DOHC, 4 valves/cyl DISPLACEMENT 268.2 cu in/4,395 cc 305.1 cu in/5,000 cc 333.3 cu in/5,461 cc 293.3 cu in/4,806 cc COMPRESSION RATIO 10.0:1 9.5:1 10.0:1 10.5:1 POWER (SAE NET) 567 hp @ 6,000 rpm 550 hp @ 6,000 rpm 577 hp @ 5,500 rpm 570 hp @ 6,000 rpm TORQUE (SAE NET) 553 lb-ft @ 2,200 rpm 502 lb-ft @ 2,500 rpm 561 lb-ft @ 1,750 rpm 590 lb-ft @ 2,500 rpm REDLINE 7,000 rpm 6,400 rpm 6,400 rpm 6,700 rpm WEIGHT TO POWER 9.1 lb/hp 9.8 lb/hp 9.3 lb/hp 9.1 lb/hp TRANSMISSION 8-speed automatic 8-speed automatic 7-speed automatic 8-speed automatic AXLE/FINAL-DRIVE RATIO 3.15:1/2.02:1 3.31:1/2.21:1 3.69:1/2.69:1 2.92:1/2.01:1 SUSPENSION, FRONT; REAR Control arms, coil springs, adj shocks, adj anti-roll bar; multi-link, air springs, adj shocks, adj anti-roll bar Control arms, air springs, adj shocks, adj anti-roll bar; multi-link, air springs, adj shocks, adj anti-roll bar Control arms, air springs, adj shocks, adj anti-roll bar; multi-link, air springs, adj shocks, adj anti-roll bar Control arms, air springs, adj shocks, adj anti-roll bar; multi-link, air springs, adj shocks, adj anti-roll bar STEERING RATIO 17.9:1 17.6:1 17.4:1 15.9:1 TURNS LOCK-TO-LOCK 2.7 2.8 2.8 2.6 BRAKES, F;R 15.2-in vented, drilled; 15.2-in vented, drilled, ABS 15.0-in vented disc; 14.4-in vented disc, ABS 15.4-in vented, drilled, grooved disc; 13.6-in vented, drilled, grooved disc, ABS 16.5-in vented, drilled, carbon-ceramic disc; 14.6-in vented, drilled, carbon-ceramic disc, ABS WHEELS 10.0 x 21-in; 11.5 x 21-in, cast aluminum 9.5 x 21-in, cast aluminum 10.0 x 22-in; 11.5 x 22-in, cast aluminum 10.0 x 21-in, cast aluminum TIRES 285/35ZR21 105Y; 325/30ZR21 108Y Michelin Pilot Super Sport 275/45R21 110Y Michelin Latitude Sport 285/40ZR22 106Y MO; 325/35ZR22 110Y MO Continental Conti Sport Contact 295/35R21 107Y Yokohama Advan Sport N2 DIMENSIONS WHEELBASE 115.5 in 115.1 in 114.8 in 114.0 in TRACK, F/R 65.6/65.6 in 66.5/66.3 in 65.9/66.7 in 65.4/65.9 in LENGTH x WIDTH x HEIGHT 193.8 x 78.3 x 66.5 in 190.9 x 78.1 x 68.1-72.6 in 192.6 x 78.9 x 67.7 in 191.1 x 78.7 x 64.9-69.2 in GROUND CLEARANCE 8.1 in 8.4-10.9 in 7.8 in 6.4-10.7 in APPRCH/DEPART ANGLE 18.3/20.3 deg 22.4-30.0/22.5-27.3 deg 22.4/24.5 deg 22.2-29.8/21.0-26.7 deg TURNING CIRCLE 42.0 ft 40.4 ft 38.7 ft 39.0 ft CURB WEIGHT 5,187 lb 5,412 lb 5,359 lb 5,187 lb WEIGHT DIST., F/R 51/49 % 52/48 % 54/46 % 53/47 % TOWING CAPACITY 6,500 lb 7,716 lb 7,200 lb 7,716 lb SEATING CAPACITY 5 5 5 5 HEADROOM, F/R 39.9/37.9 in 39.4/39.1 in 38.9/38.5 in 39.6/38.9 in LEGROOM, F/R 40.3/35.6 in 42.2/37.0 in 40.3/38.4 in 41.0/36.5 in SHOULDER ROOM, F/R 60.5/57.9 in 60.7/59.5 in 58.5/58.4 in 58.9/56.1 in CARGO VOL BEHIND F/R 59.7/26.6 cu ft 62.2/27.7 cu ft 60.7/23.0 cu ft 60.2/23.7 cu ft TEST DATA ACCELERATION TO MPH 0-30 1.4 sec 1.5 sec 1.4 sec 1.5 sec 0-40 2.0 2.3 2.1 2.2 0-50 2.8 3.2 2.9 3.2 0-60 3.7 4.3 3.9 4.2 0-70 4.7 5.6 5.0 5.6 0-80 5.9 6.9 6.5 7.3 0-90 7.4 8.6 8.2 9.0 0-100 9.0 10.4 10.0 11.1 PASSING, 45-65 MPH 1.8 2.1 1.9 2.1 QUARTER MILE 12.1 sec @ 114.3 mph 12.7 sec @ 110.1 mph 12.5 sec @ 110.5 mph 12.9 sec @ 107.4 mph BRAKING, 60-0 MPH 105 ft 125 ft 112 ft 107 ft LATERAL ACCELERATION 0.98 g (avg) 0.84 g (avg) 0.93 g (avg) 0.93 g (avg) MT FIGURE EIGHT 24.3 sec @ 0.84 g (avg) 25.8 sec @ 0.76 g (avg) 25.2 sec @ 0.77 g (avg) 24.6 sec @ 0.83 g (avg) 2.42-MI ROAD COURSE LAP 92.46 sec 98.78 sec 96.00 sec 94.32 sec TOP-GEAR REVS @ 60 MPH 1,500 rpm 1,800 rpm 1,600 rpm 1,400 rpm CONSUMER INFO BASE PRICE $103,095 $111,470 $110,225 $158,295 PRICE AS TESTED $115,195 $126,645 $115,880 $175,930 STABILITY/TRACTION CONTROL Yes/Yes Yes/Yes Yes/Yes Yes/Yes AIRBAGS Dual front, front side, f/r curtain, front knee Dual front, front side, f/r curtain Dual front, f/r side, f/r curtain, driver knee Dual front, f/r side, f/r curtain, front knee BASIC WARRANTY 4 yrs/50,000 miles 4 yrs/50,000 miles 4 yrs/50,000 miles 4 yrs/50,000 miles POWERTRAIN WARRANTY 4 yrs/50,000 miles 4 yrs/50,000 miles 4 yrs/50,000 miles 4 yrs/50,000 miles ROADSIDE ASSISTANCE 4 yrs/Unlimited miles 4 yrs/50,000 miles Unlimited 4 yrs/50,000 miles FUEL CAPACITY 22.4 gal 27.7 gal 24.6 gal 26.4 gal EPA CITY/HWY/COMB ECON 14/19/16 mpg 14/19/16 mpg 14/18/15 mpg 14/21/17 mpg ENERGY CONS., CITY/HWY 241/177 kW-hrs/100 miles 241/177 kW-hrs/100 miles 241/187 kW-hrs/100 miles 241/160 kW-hrs/100 miles CO2 EMISSIONS, COMB 1.22 lb/mile 1.22 lb/mile 1.25 lb/mile 1.18 lb/mile RECOMMENDED FUEL Unleaded premium Unleaded premium Unleaded premium Unleaded premium

    PDU stands for Performance Design Unlimited. They are a new vendor on BimmerBoost located in California and are showing off their N55 products. A great way to show them off is in real world comparisons against some fast cars and that is exactly what they do in the video below. The F22 M235i is upgraded with the Pure Turbos Stage 2 N55 turbocharger. Obviously this turbo can make quite a bit of power which is where the PDU Port Fuel Injection system comes in. The car is also running a JB4, ACF tune, and 100% E85. The N54 gets the lion's share of attention but it is nice to see the N55 taking down some stiff competition and getting tuning attention. Take a look at the runs. The F10 M5 is tuned with the a BMS Stage 1 piggyback. The M235i easily pulls away and puts some distance on the F10 M5 which is no slouch. A very impressive pull. Next up is a Nissan GTR with full bolt ons and a Cobb Stage 3 tune. The M235i puts up a really good fight but the GTR once it gets into the higher gears shows its muscle. As well all know a full bolt on GTR is an impressive performer. Next up are a pair of E92 M3's one of which is ESS supercharged. Both are trounced easily as is the ESS car which happens often when one races anywhere other than on a keyboard. The Huracan run is next and the M235i jumps early. The Huracan stays in for a bit and let's off. Based on the previous results the M235i should win but a Huracan run should be closer with a better start. A stock F82 M4 is up next and the car visibly spins and can not get traction. An ugly beatdown. The second run is even worse. The final run is a drag race against an ESS supercharged E92 M3. Yet another ESS loss. What we gather from this is @PDU's fuel system is the real deal and the N55 can be made quite formidable with some upgrades. This M235i performs very well.

    Performance driving tends to be a man's domain. From Formula 1, to rally racing, to drifting, to you name it. There are exceptions of course and professional Malaysian drift driver Leona Chin is one of them. She poses as a clueless Mitsubishi sales girl selling the 2015 Mitsubishi Triton. The truck is not exactly a powerhouse with 178 horsepower and 295 lb-ft of torque from the 2.5 liter turbo diesel but it is enough power to scare the crap out of the potential male buyers when she takes the wheel and drifts the truck. There are a lot of lulz to be had in this video as you see and hear some of the men try and flirt with her as well as tell her that the vehicle is a man's car. The guy who tells her it is a man's car ends up asking her to stop driving which we assume she wanted to push him to the limit in particular. Enjoy the vid which is good for some laughs and never underestimate a driver based on their looks.

    MotorTrend starts the year off right with a Head 2 Head episode pitting the new Gen V Dodge Viper ACR against the 2015 Chevrolet Corvette Z06. We do not have to tell you how impressive the Dodge Viper ACR is. It is the baddest track on the planet for the money. MotorTrend's Jonny Lieberman starts off by saying Dodge's documented claim of thirteen lap records for the ACR is similar to your mom telling you that you are good looking. Not a good analogy at all and quite disrespectful to the achievement. A subjective point on looks from a family member is not at all the same as objective results with data to back up them up. Dodge backed them up thirteen times and it is not like they are stopping anyone from trying to top them. Just a dumb point right off the bat that places MotorTrend's self-serving tests as the supposed standard. Remember that MotorTrend had issues with the C7 Z06. The car was not able to complete their best driver's challenge last year. Chevrolet states they fixed the problems and so MotorTrend gets another crack at track testing with the car. The straightline and braking battle goes to the ACR although we do not know if MotorTrend's numbers are from testing on the same day. If so, the ACR manages to have the higher trap speed despite the drag from the extra downforce. Impressive. Randy Pobst takes the cars out to Laguna Seca but before they test the Americans a German is thrown in for context. That German being yet another one of the best track cars and dedicated driver's cars in the world known as the 911 GT3 RS. It sets the bar at 1:33.29 despite Pobst struggling somewhat with oversteer. That is quick and a new record but both the Z06 and Viper ACR quickly top it. Lap Times: GT3 RS: 1:33.29 Z06: 1:33.05 ACR: 1:30.46 That ACR beats the GT3 RS and Z06 soundly. The Z06 is able to edge the Porsche by just over 2/10's but the ACR is just over 2.5 seconds quicker. A significant amount as you can see in the video when the two laps are juxtaposed. The Viper ACR is just flat out spectacular and one of the best track cars in the world at any price point. There is nothing else to say.

    Stock internal 2015 Mustang GT? Check. Whipple 2.9 liter twin screw supercharger? Check. Drag tires? Check. MS109 race gas? Check. Stock manual transmission? Check. Put all that together and you get a 2015 Mustang GT that runs 9's in the 1/4 mile at over 150 miles per hour of trap speed. We knew the Whipple 2.9 liter supercharger made quite an impact on the new Mustang GT S550 models. On 91 octane pump gas it adds 317 horsepower to the rear wheels for numbers in the mid 600 to the wheels range. What is it doing on MS109 race gas with custom tuning from Lund Racing? That's a good question but we would venture to guess quite a bit more. The 1/4 mile result certainly is impressive to say the least. As is the 1.47 60 foot time.

    A Lamborghini catching fire is nothing new. It can even happen to a car that is stock. With high horsepower built twin turbo examples there certainly is a lot more heat generated and accidents can happen with such builds such as what you see in the video here. That is why it is puzzling that rather than addressing the issue Underground Racing is attempting to sweep it under the rug. We all know they have some of the strongest Audi/Lamborghini V10 builds in the world. As a matter of fact, this car set a record before burning down and UGR is touting the record but ignoring what happened to the car. Why are they being so insecure here? UGR apparently forced MotorTrend who was at the event and caught this Gallardo catching fire on video to pull their footage. They apparently have forced others to delete their videos as well. That even includes deleting comments about the incident: That seems a bit paranoid, doesn't it? Deleting comments? Pulling videos? Blocking users from commenting on social media? This network does not believe in such censorship by tuners. We want to know what happened and for customers as well as potential customers to be made aware of any issues as their safety is the primary concern here. Underground Racing is handling this issue poorly and enthusiasts do not appreciated being bullied by tuners. Rest assured this article is not going anywhere.

    How does $51,700 for the upcoming 2016 F87 M2 sound? What do you get for that money? A 3.0 liter turbocharged inline-6 with output of 365 horsepower and 343 lb-ft of torque which no doubt is underrated. That money also buys the lightest M car in the lineup short of the M4 GTS which is more than twice the price but we want to see independent weight tests for both. You also get a car for the money capable of lapping the Nurburgring in under 8 minutes. With some aftermarket suspension tweaks and maybe the addition of a water injection system one can expect the M2 to be a potent track car. The engine itself is a closed deck block based on the N55. BMW did not make the same mistake with the M2 as they did with the 1M where they just used an engine they had laying around only changing the software. The M2 gets a real M motor despite not it not having an M designation as odd as that is. The 2016 X4 M40i will share the same engine and hit the streets next month which is before the M2's expected April debut. Say hello to the best performance value in the M lineup. THE 2016 NORTH AMERICAN INTERNATIONAL AUTO SHOW IN DETROIT: - BMW to announce pricing of the all-new 2016 BMW M2. - BMW to announce pricing of the all-new 2016 BMW X4 M40i. Woodcliff Lake, N.J.: January 11, 2016 10:30 am EST /7:30 am PDT ... Today, the all-new BMW M2 and all-new BMW X4 M40i made their world debut at the 2016 North American International Auto Show in Detroit. The 2016 BMW M2. Making its highly anticipated world debut, the first ever BMW M2 features the renowned BMW M performance complimented by a sleek interior and exterior design. The new entry model of the BMW M GmbH is perfectly aligned with M tradition ensuring unbeatable driving dynamics on the roads and the track, embodying the true DNA of BMW M vehicles. A newly developed M TwinPower Turbo technology 3-liter, 6-cylinder engine produces 365 bHP and 343 lb-ft of torque between 1,400 and 5,560 with an overboost function raising this figure to 369 lb-ft between 1,450 and 4,750 catapulting the high performance vehicle from 0-60 mph in 4.2 seconds ( M DCT) with a top speed of 155 mph. Inspired by its motorsport roots, the BMW M2 sets the pace in its segment when it comes to agility, driving feeling, directional stability, steering precision and controllability at the limit, without any compromise in everyday use. The 2016 BMW M2 will be available at authorized BMW centers starting at $51,700 plus Destination and Handling starting in April 2016. The 2016 BMW X4 M40i. The cutting-edge drive technology in the new BMW X4 M40i guarantees the free-revving thrill typical of a BMW M developed motor and its outstanding power delivery. With 355 hp and 343 lb-ft of torque, the newly developed M Performance TwinPower Turbo technology inline 6-cylinder engine will also be making its world debut. Reaching an electronically limited top speed of 150 mph, the BMW X4 M40i delivers best-in-class acceleration, traveling from 0-60 mph in just 4.7 seconds.

    This is getting ridiculous. We were already blown away by the Gen V Viper making quadruple digit horsepower on the stock motor this early on in its tuning. A tuner by the name of Unleashed Tuning managed to hit 1002 horsepower to the wheels on 93 octane. Calvo Motorsports has taken things quite a bit further on 93 octane pump gas with 1187 rear wheel horsepower and 1175 lb-ft of torque at the wheels. What allows this kind of pump gas power? It is tuned on a Motec M1 standalone ECU. Calvo's tuner believes they could easily get it over 1200 whp on pump as well but they think they are pushing the motor far enough as is. No knock, no detonation, and no issues with almost 1200 whp on 93 octane pump fuel. The scary thing is it can go further but nobody wants to be the first one to find the limit of the Gen V Viper internals. What can you say? The new Viper is badass.

    Well, this is a new horsepower for turbocharged Porsche flat-6 motors. The record previously stood at 1560 horsepower from a 996 Turbo tuned by Undercover Performance on a ProEFI ECU. That was also achieved with nitrous though and what makes the new record remarkable is it is boost only. Thanks to a Protomotive Built 4.2 liter flat-6 motor and boost from a pair of Forced Performance 3794 turbochargers this 997 GT2 achieves 1564 horsepower and 1189 lb-ft of torque to the wheels. That is on E85 fuel and 33.3 psi of boost. What would the numbers be on a Dynojet? We are not sure but probably a bit less. It is also conceivable that the car has more in it. We do not have any more details and the owner is not sharing any photos. It seems he wants to let the car do the talking at 1/2 mile roll on events. It's not going to have any trouble getting its competition talking, that is for sure.

    This is one we have been dying to see. Two American supercharged V8 brutes with four doors and a ton of power. The CTS-V of course features the LT4 supercharged and direct injected 6.2 liter V8 from the Corvette Z06 although it is 'detuned' to 640 horsepower and 630 lb-ft of torque. That is less power and torque than the 707 horsepower from the twin screw supercharged Hemi Hellcat 6.2 liter V8. Less torque as well as the Charger Hellcat is rated at 650 lb-ft of torque. The ratings do not tell the story as both of these engines are underrated. The Hellcat dynos in the ~660 wheel horsepower range with ~600 lb-ft of torque at the wheels. The LT4 does not give up any torque and actually shows slightly more torque on some dyno runs but it is down by roughly ~70 rear wheel horsepower. The Hellcat's bigger 2.4 liter twin screw blower appears to have a distinct advantage. The Hellcat needs that power to move its heavy 4560 pound behind. The CTS-V is no lightweight but it is a significant ~400 pounds lighter. Both cars have 8-speed automatic transmissions. How does it play out? The first dig race has the Hellcat come out on top. The owner decides to give the CTS-V the hit on the second run and the CTS-V pulls away as the Charger spins its tires. It is interesting to note that the Hellcat does start to reel the Caddy in up top and would have passed it if the CTS-V did not shut down. They move to roll races after this but there is some miscommunication in the first run as the Hellcat gets on the gas then gets off to get back on again. The second run offers a cleaner start and the Hellcat decisively pulls. Great runs here between the two supercharged beasts but the bigger beast is the Hellcat. The amount of power Dodge is giving consumers for the money is simply incredible.

    The E60 M5 camera car in the video belongs to BimmerBoost member @tjav8b. His car is no slouch in stock form thanks to the S85 5.0 liter V10 under the hood but his is not stock. It is boosted courtesy of a Vortech based supercharger kit meaning it is quite potent especially on the top end. He decided to take his car to a 1/2 mile race event in Florida where there was a variety of competition. Competition that included this CTS-V that suddenly just pulls away like the M5 is standing still. We do not know the modifications on the CTS-V. All we know is it is impressive to say the least. The CTS-V trapped over 170 on this run and the M5 managed 159 miles per hour. Thank you @tjav8b for sharing the video and not caring about a win or loss.

    A discussion on the BimmerBoost BMW Performance forums regarding a weak F80 M3 and F82 M4 S55 flash tune touched off a debate on the state of BMW F-Series flash tuning and the current capabilities. You may remember that the BMW F-Series Tricore ECU's were cracked at the end of 2014 allowing limited flash tuning. Limited is correct as nobody is doing any OBD-II flashing of BMW F-Series models. At least not without a bench flash first which means physical access to the ECU is necessary. Some people think we will not have OBD-II flash tuning for the F-Series any time soon if ever at all. So what is the solution? Why is flash tuning important? Well, piggyback tunes can only influence parameters in the ECU that are already there. They can not change the programming. Flash tunes can change the programming. You see new flash tunes popping up all the time for the new turbo BMW models. What many don't realize is most of these flashes are the exact same thing from the exact some source. One source is BR Performance in Belgium. Basically, a tuner buys the tools or codes to 'flash' the F-Series ECU from a certain source. This is essentially a crack that allows certain modifications to the software. Tuners then claim to be able to flash but really they are modifying a small set of parameters without complete definition of all the software tables and files. Everyone sells this flash software and charges money for that flash. This is how tuners make money on software. Some tuners have more access than others and some use different sources. The thing is, for the vast majority, they are just reselling the same damn thing which has limited capability due to this early stage of tuning without all the parameters being defined. Some blind tuning takes place and much of it is trial and error. Playing it safe by modifying only certain aspects that everyone modifies is the easiest course of action and what most tuners are doing. The tuner at ACM (Autocouture Motoring) went on the BimmerBoost forums and posted these results for an F10 M5 they tuned: Over 800 wheel horsepower is impressive, right? Especially with a flash tune. That flash tune is only part of the picture as this setup relies on a BMW JB4 piggyback and a boost control module as well: F10 M5 mods: -ACM S3 flash tune -Pure S1 turbos -BMS JB4 + BCM -AMS downpipes -Meth -Dodson clutches -Full Akrapovic -MSR intake -93 octane In order to get the most out of a turbo upgrade or even basic tuning on the F-Series almost necessitates using a piggyback to influence the factory ECU parameters. If tuners had complete control of the ECU they could do this all with a flash by itself. They don't. We do have limited tuning capability of the F-Series ECU today but we are going to see these sort of hybrid tune setups for a while. We already saw similar things take place in the N54 world. Things will progress but as BMW is the most unfriendly company in existence to enthusiasts who want to modify their own cars reverse engineering BMW's work is practically impossible without inside factory sources helping things along. Brute force cracking attempts take forever with the encryption employed these days and is sort of like trying to win the Lotto. Even Dinan had to quit that approach and go the piggyback route. Keep all of this in mind when tuners discuss flash tuning capabilities on the F-Series. Most overstate what they can do in order to get sales. Nobody has real control of the ECU software except BMW.
