    N54 turbo inlets. This topic has caused a civil war on the BimmerBoost forums. TFT (Trueform Technologies) weighed in on the controversial topic and posted results with their inlet and charge systems. The numbers they are showing certainly are impressive. How does 670 horsepower to the wheels on an E70 blend with an FFtec inline LPFP pump upgrade sound? No port injection here: Original RB Turbos (cast wheels) TFT Inlet System and Charge System AMS Intercooler, AR Downpipes Tuned by Brian@TFT, via MHD Flasher Regarding the inlets, TFT stated the following: "With the rapid roll-out of these cheap inlet systems put together as afterthoughts hitting the market soon, one can't help but reference the timeless phrase: "You get what you pay for", and while some replica inlet systems might appear similar to the TFT Inlet Systems from afar, the important value is in the details. With that in mind, here is the latest from the TFT 335i - showing how effective, powerful, and issue-free the right parts (and the right combination of parts) can truly become. Next up: custom billet compressor wheels (properly sized of course) and 700whp!" This car is clearly capable of much more. We will see what they hit as the N54 inlet war rages on.

    People are already asking about it though so we will start accepting people for open spots. Priority goes to last year's participants. The format will be the exact same except with three commissioners. If you wish to be a commissioner you can apply now and it will be determined based on league votes. Policy changes in the league will be based on commissioner votes. We did $100 last year and it kept everyone involved for the most part. I'm happy to do $100 again as I doubt most will go for more: Payout at $100 would be as follows: 1st place: $900 2nd place:$200 3rd place: $100 Payments through paypal. Address: This is last year's roster and people on it get priority for this year. There are currently three open spots: 1. @Sticky PAID 2. @135pats PAID 3. @chrisisnapping PAID 4. @Legionofboom PAID 5. @Terry@BMS PAID 6. @nafoo PAID 7. @Group.america PAID 8. @zeenon53 PAID 9. @Tony@VargasTurboTech PAID 10. cadillacgrills PAID 11. open 12. open There will be a trophy this year as well that goes to the winner. I'm thinking about making my own trophy. Welding some old turbo on some wood. Something like that. Thoughts?

    A lot of great action in this video here! It starts out with a three-way race between E60 M5's with different modifications but all naturally aspirated. The camera car is the blue E60 M5 in lane three that features an Evolve Automotive tune along with the Evolve tubular headers. It is the headers that make the biggest difference here and it shows as the two black E60 M5's get a large jump but the blue E60 M5 camera car is able to run them down pulling harder up top. The basic mods between all three are the same with each featuring intake scoops, an underdrive pulley, cats deleted, and a tune. If anyone was wondering if headers make a large difference wonder no more. The second run between the trio features a far more even start. The blue E60 M5 again demonstrates its top end power superiority pulling past the other two. The other two M5's are basically neck and neck as they should be. The amount of weight in the car is enough to separate them. The third run again has the blue M5 pulling decisively and at this point it is well established it is the fastest out of trio. The fourth race is the one that is most interesting putting things in context as the fastest E60 M5 takes on a Stage I BMS tuned F10 M5 that is tune only. The S85 V10 top end shows well here against the F10 M5 which gets pulled. They run again and the race is closer but the E60 M5 again pulls up top. The F10 M5 looks to be running a very mild map based on the result but the S85 V10 strength is top end highway runs and it shows. A great video with great races.

    Impressive power here numbers from the upcoming FSR Motorsport E46 M3 turbo kit. This kit is not yet released and BimmerBoost explored this turbo option last week. BimmerBoost member @6spd_legend has the pre-production kit and his car showed an impressive 720 horsepower to the wheels at 19 psi. Torque is at 538 lb-ft at the wheels and yes this on a completely stock E46 M3 S54 motor: Tuning is done through the AEM Infinity standalone engine management unit. As far as pricing, the kit is expected to come in at $9k and goes up from there with additional options such as larger injectors and upgraded fuel pumps. Further details: We're selling our Pre-Production S54 turbo kit. This kit is dyno proven to make 650whp in current setup. You can add larger injectors, additional fuel pumps or a larger turbocharger to make even more power. The kit contains the following used components: Precision 6466 dual ball bearing turbocharger, Turbosmart Hypergate45, FSR stainless steel tubular manifold, stainless steel dump tube, FSR stainless steel downpipe/midpipe combo that mates to OE exhaust, 6061 AL hot and cold side intercooler piping, Precision 31 1/2"L X 8.0"H X 3 1/2"D Intercooler with mounting brackets, turbosmart Raceport blow off valve, FSR fabricated intake manifold, intake with filter, oil feed and return lines with fittings, black couplers, SS clamps, FSR motor mount w/ bushing, hardware to mount turbo/manifold/intercooler, boost actuated exhaust cutout. You also get the following NEW items: AEM Infinity pkg for E46 M3 (includes AEM Infinity ECU, adapter harness, 5 bar SS map sensor, 150psi fuel pressure sensor, intake air temp sensor, wideband adapter harness, wideband sensor, boost control solenoid), Fuel Injector Clinic (FIC) 1100cc Hi Impedance fuel injectors, Walbro E85 compatible 400lph fuel pump (also called the 460/465/485) and Radium Engineering E46 M3 fuel pump install kit. It has been used on our shop car for dyno and road testing so it does show a little wear.

    This is definitely going to upset the AMG fanboys as the M157 5.5 liter twin turbo V8 motor in the E63 AMG has enjoyed an advantage over the M5 S63TU 4.4 liter twin turbo V8 for some time in the aftermarket. F10 M5 S63TU tuning evolved considerably since flash tuning solutions were released this year and it shows. In the left lane you have a pre-facelift E63 AMG model which means it is rear wheel drive and does not have 4Matic all wheel drive. The F10 M5 in the right lane is also rear wheel drive of course. Both cars have flash tunes from Eurocharged and both cars have catless downpipes. This is as close to apples to apples as you will get. The cars go at it from a low speed roll and the E63 has a slight jump. The F10 M5 on the gearshifts catches up and it certainly looks like the DCT transmission in the M5 is providing an advantage compared to the E63 AMG MCT automatic. The M5 ends up pulling past the E63 and up top despite starting behind it. Certainly an impressive display by the M5.

    This picture says quite a lot. Namely that the oem BMW 335i N54 turbos are tiny. Fortunately there are two of them but when seeing the size of the turbo compared next to a GTX30R the N54 oem turbocharger looks like a little itty bitty baby turbocharger does it not? That is what makes the fact these OEM housings are hitting almost 700 wheel horsepower all that more impressive. It truly is remarkable when put in this type of context. It also shows just how good of a job the turbo vendors are doing on the platform.

    This era of engine efficiency is bringing with it turbochargers and smaller motors. With naturally aspirated high revving motors being slowly phased out (with exceptions) redlines have dropped a bit. This affects even lofty producers such as Ferrari who historically managed to offer some of the highest revving motors seen in production cars. You will notice however that naturally aspirated motors still dominate when it comes to high revs. This list is in order of highest to lowest redline. It also favors new motors and not motors being phased out. That means we did not omit the M159 V8 of the Mercedes SLS Black Series we simply realize it has reached the end of its lifespan and the M178 twin turbo V8 is replacing it. The same reasoning is why we do not list the Ferrari 458 naturally aspirated V8 but instead the 488 GTB turbocharged successor taking its place. Enjoy the 2015 list. 1.

    The demise of HPF (Horsepower Freaks) left somewhat of a void in the BMW E46 M3 turbo scene. Legitimate BMW forced induction specialists stepped in to fill that void and there are options from Maximum PSI on the factory ECU and Saad Racing using aftermarket ECU's. FSR Motorsport in California is preparing a turbo kit based around the AEM Infinity engine management system. So what else can we tell you about their offering? Not much other than they will use a Precision turbocharger. There is literally nothing else to share except a video of the FSR development car on the dyno but a dyno video without a graph or details is rather pointless. Will this be a solid option on the platform? Maybe. They have been working on this since 2012 and we are deep into 2015 now. Without solid details, specifications, and results it will continue to bask in obscurity. <blockquote class="instagram-media" data-instgrm-version="4" style=" background:#FFF; border:0; border-radius:3px; box-shadow:0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width:658px; padding:0; width:99.375%; width:-webkit-calc(100% - 2px); width:calc(100% - 2px);"><div style="padding:8px;"> <div style=" background:#F8F8F8; line-height:0; margin-top:40px; padding:50% 0; text-align:center; width:100%;"> <div style=" background:url(data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAACwAAAAsCAMAAAApWqozAAAAGFBMVEUiIiI9PT0eHh4gIB4hIBkcHBwcHBwcHBydr+JQAAAACHRSTlMABA4YHyQsM5jtaMwAAADfSURBVDjL7ZVBEgMhCAQBAf//42xcNbpAqakcM0ftUmFAAIBE81IqBJdS3lS6zs3bIpB9WED3YYXFPmHRfT8sgyrCP1x8uEUxLMzNWElFOYCV6mHWWwMzdPEKHlhLw7NWJqkHc4uIZphavDzA2JPzUDsBZziNae2S6owH8xPmX8G7zzgKEOPUoYHvGz1TBCxMkd3kwNVbU0gKHkx+iZILf77IofhrY1nYFnB/lQPb79drWOyJVa/DAvg9B/rLB4cC+Nqgdz/TvBbBnr6GBReqn/nRmDgaQEej7WhonozjF+Y2I/fZou/qAAAAAElFTkSuQmCC); display:block; height:44px; margin:0 auto -44px; position:relative; top:-22px; width:44px;"></div></div><p style=" color:#c9c8cd; font-family:Arial,sans-serif; font-size:14px; line-height:17px; margin-bottom:0; margin-top:8px; overflow:hidden; padding:8px 0 7px; text-align:center; text-overflow:ellipsis; white-space:nowrap;"><a href="" style=" color:#c9c8cd; font-family:Arial,sans-serif; font-size:14px; font-style:normal; font-weight:normal; line-height:17px; text-decoration:none;" target="_top">A video posted by FSR Motorsport Creations (@fsr_motorsport_creations)</a> on <time style=" font-family:Arial,sans-serif; font-size:14px; line-height:17px;" datetime="2015-07-02T17:00:30+00:00">Jul 2, 2015 at 10:00am PDT</time></p></div></blockquote> <script async defer src="//"></script>

    This is something we are going to see more of as the new M3 and M4 battle with the 335i and 135i models equipped with the N54 (with N55's more and more getting into the mix as well). This goes down about as one would expect with the F80 M3 pulling up top. The M3 has the advantage of the DCT transmission. The Eurocharged ECU flash tune with downpipes as this M3 has boosts things considerably. Basically, a bolt on F80 M3 should make a bit more power than a bolt on E9X 335i N54 but the N54 has some additional tricks up its sleeve that this particular example is not running including inlets and E85. This particular N54 is running meth injection though and the F80 M3 S55 is not which is a factor although it is on race gas. Ultimately, these are both 3.0 liter twin turbo direct injected BMW inline-6 motors and which is faster comes down to the amount of mods and really money spent. The M3 will ultimately have the advantages of the DCT transmission and the higher redline. It also is the more complete package to begin with. It's a bit of a shame these are chase view runs on the video (it should be a crime really) but it goes to show how quick a tune and downpipes M3/M4 is and how it stacks up to a bolt on N54.

    Always good to get more dyno numbers for the new M177 twin turbo 4.0 liter V8 motor under the hood of the W205 Mercedes-AMG C63 and S models. The C63 AMG S 503 horsepower of course being higher than the 469 horsepower in the standard C63 AMG model. This output difference is due to software only so owners of the base C63 AMG should not fret as they can easily match and exceed the C63 AMG S. Speaking of which, 503 horsepower using 17% drivetrain losses for an automatic on a Dynojet which is the traditional figure results in 417 horsepower to the wheels. The C63 AMG S is not losing only 24 horses or 4.8%. The car is underrated quite a bit in power and is producing closer to ~565 horsepower at the crank. The torque figure is really underrated at 495 lb-ft at the wheels which is more like ~585 lb-ft of torque at the crank. It is interesting to note that the C63 AMG S M177 and the AMG GT S M178 both have similar peak wheel horsepower figures however the M177 is producing more peak torque at the wheels by roughly 40 lb-ft. That is a sizeable difference. Thank you to BenzBoost user @CarlBENZ for this graph. We will soon have tuned figures from him as he intends to purchase a Rebellion piggyback box and dyno the results afterwards.

    Here's a video of a Eurocharged F80 M3 with downpipes and race gas vs a JB4 N54 335i with FBO, 94oct, Meth and stock turbos running the BMS backend race flash without the modified knock tables. All runs were done in Mexico. First run the N54 was on a 60 additive and second run the N54 was on a 75 additive.

    An interesting photo was posted from a BMW technical document on the BimmerBoost forums that gives a quick and easy overlay of the BMW N54 and N55 valvetrains including their VANOS camshaft adjustment ranges. The N54 and N55 of course are similar turbocharged and direct injected inline-6 motors sharing the same bore and stroke. They clearly are tuned a bit differently (due to the N55 being single turbo for one) and the N55's addition of Valvetronic plays a role. The N55 has a wider range of intake and exhaust VANOS adjustment as well as larger intake valve lift and cam duration compared to the N54 as the tech document highlights. Potentially the N55 can breathe better up top namely with a large turbo upgrade although tuning VANOS as well as Valvetronic is complicated. VANOS alone is a difficult system to tune and we have yet to see aftermarket VANOS cams working for the N54 or N55 motors. An interesting comparison nonetheless.

    Fluid MotorUnion does some outside the box thinking and quirky things although many of them are form over function. We would like to reference their BMW E9X M3 S65 V8 velocity stack system as support for this as an example. They may be onto something here though. The McLaren F1 uses gold foil in the engine bay as a heat reflector. It looks like Fluid MotorUnion is trying to take the same approach here to prevent heat soak and keep the M5 air boxes cooler by applying gold foil wrap to them. In theory this of course should work as gold is an excellent heat reflector. We would like to see some data in support of the function though rather than pictures of how cool it looks under the hood.

    Positive displacement versus centrifugal superchargers. An age old argument in automotive performance circles and one that will likely never end. The vast majority of E9X M3 S65 V8 supercharger kits use centrifugal blowers such as the Vortech unit employed by this ESS kit. There is a reason for this. They are easier to tune for on the factory computer especially early on in the case of the E9X M3. BMW DME's are not easy to figure out which is why the Harrop kit has taken a few years to come to market. BimmerBoost first encountered it back in early 2013. There were already five (and counting) centrifugal based supercharger kits available for the M3 at that time but zero positive displacement solutions. Part of this is due to the S65 V8 independent throttle bodies. As a positive displacement unit such as the Harrop with its Eaton TVS 1740 roots blower always makes boost this poses a bit of a problem. Usually a roots or twin screw blower will pull air through a throttle body and not blow air into it or into eigh in this case. A bypass valve designed to bleed excess pressure is Harrop's solution and really is the only solution but getting the DME to play nicely with this setup is tough work. The benefit though is torque down low and better throttle response. A centrifugal kit like the ESS unit is peaky and offers poor throttle response in comparison. As the Vortech blower needs to be spun to make boost the power comes up top and takes a while to build. The higher you rev it, the more air it will move. The Eaton unit on the other hand provides roughly the same boost from idle to redline. There is also the difficulty of packaging a positive displacement unit so the Harrop kit is limited to an Eaton TVS 1740. This is not going to make as much power as the centrifugal kits up top but it will provide more torque down low and do so consistently through the curve. What it really comes down to is, do you want throttle response and torque or do you want top end horsepower? A centrifugal kit should pull up top and a TVS based kit should pull off the line and initially in a race. That is exactly what you see in this race below. What would BimmerBoost's choice be? The best of both worlds, turbos.
