    • SRM1000 Porsche 997.2/991 3.8 upgrade package hits 947 awhp on factory ecu and stock 991.1 Turbo engine internals

      Now this is cooking! How about a Porsche 991.1 Turbo making 948 horsepower to all four wheels and tuned on the factory ecu? Also, achieving that number on the stock engine internals and the factory transmission?


      That is what SRM (Silly Rabbit Motorsport) hit with their SRM1000 package and their Porsche 991.1 Turbo.

      There are not many details on this package and what you will see is a PorscheBoost exclusive.

      Let's start with the graph:


      948 to the wheels on a Mustang is not a joke. Keep in mind this is done on the World Motorsports Mustang which reads closer to a Dynojet. A ton of power on the factory the engine internals and the factory transmission regardless.

      Fuel is supplied with supplemental port injection. ID1700 injectors and the SRM brushless fuel pump upgrade.

      This car will be dyno'd again shortly but the current result is fantastic. More SRM1000 details to come after the next dyno session.

        Backed that up with 4.59 60-130

        Which is really slow for that figure IMO.

        People are hitting 4.8s with OTS VTG68 at 800whp. This car making that kind of power should be in the 3.8, just like Daves car is at.

        Slow on wet pavement?

        Based off the dragy run there was no traction issue and it was on a downhill slope. Hopefully we can see it reflect the power it's making with better 60-130mph times. Still impressive though! Maybe even show up to a 1/2 mile race? Click here to enlarge

        The rods in the 991 Turbo are stronger than the 997.2 Turbo, though 800ft/lbs is really pushing these 6 rods....

        Maybe the turbos they are using in the SRM1000 kit are the EFR7163's they have on their website....

        https://sillyrabbitmotorsport.com/ef...turbo-kit.html

        $6,800 (991 version includes headers)
        EFR7163 eliminator kit, bolts directly to stock manifolds and catbacks. 750whp pump gas, 1100whp e85/race

        The EFR7163 is a great turbo to use....

        The 7163 delivers incredibly fast spool and response while working well on stock and heavily modified engines. The 71mm OD compressor has a 57mm inducer and there is potential for 550hp - unheard of for this size compressor wheel. The low inertia 63mm Gamma-Ti turbine wheel is the optimal match for the 71mm FMW compressor wheel and is capable of 45+psi boost. This turbo uses the mid-size EFR ported-shroud compressor housing, great for fitment in cramped engine bays. Ideal for use in single turbo applications for the 300-550hp range, or as twin turbo applications 650-1000+hp. Ceramic Ball Bearing only, watercooling mandatory

        Wait a 2nd, the video says factory ecu, yet there is a proefi48 which I imagine controls additional injectors, how do they communicate? Also, video says stock ecu but where does it say stock motor, more importantly where does it say this is safe on factory motor, after running this much boost?

        No, they're using Xona bolt on turbo with an internal gate. It's still running a piggy back as well as flash to be able to do this.

        what type of piggy?

        Sticky will be posting a follow up article with details of the hardware/electronics/software used. None of the piggy backs on the market were able to do what we needed so developed our own in house.

        Like what? AFAIK triggering a secondary pump, PWM controlling injectors, and changing frequency for boost control is what Terry is a master of.

        Would be cool to work together to have everything integrated into one and have safety systems implemented too. Click here to enlarge
