      Here are results for the G-Power SKII CS supercharger kit results on an E92 M3 6-speed manual car from Bimmerboost vendor Precision Sport. The car dyno'd 502.6 wheel horsepower with the supercharger in SAE correction which is a substantial increase from the 339.3 wheel baseline. Keep in mind, the car has heavy 20 inch G-Power wheels which definitely affect the numbers. Regardless, the curve is very nice with a large increase in torque through the whole rev range.

      Well does PSI and great to see dynojet results for the G-Power kit.

      VEI Gauges (AFR, Boost, Water Temp)
      Custom Painted end tanks(Match G-Power manifold)





      Before and After. We dyno'd it with the 20" G-Power wheels on it.

        Those gauges are sick! Do you make those or is that part on the kit?

        And the supercharger kit is sick too. Very nice

        • G-Power SKII CS - $19k
        • AA Stage 2 $16k
        • ESS 625 $12k / 650 $14k
        • Evolve $16.5k
        • Gintani Stage 2 $15k / Stg2+ $16k
        • VF620 $13.5k / VF650 $16.5k


        It's not outrageously priced (unlike their S85 stuff), but it's still ~15% more then the next most expensive option

        ^ Where did you get that pricing?

        Off each manufacturers website (prices obviously can be negotiated, but it's their starting point). Here are the links to each s/c kits manufacturer page:

        G-Power
        Active Autowerke
        ESS Tuning
        Evolve *Taken from their thread on this site
        Gintani
        VF Engineering

        Like I said originally the G-Power stuff is second to none in terms of quality & finish, but there are several other options that are less expensive & outperform it IMO. And if you're that bent on an air/air setup, Evolve & AA are alternatives.

        Doesn't matter here in the US, but is the G-Power kit the only one with TuV approval (for the Euro crowd)?

        @bobS , the gauge pod looks a lot like the Macht Schnell pod with different gauges. They def look a lot more clean without any manufacturer labels or anything.

        And the supercharger kit is sick too. Very nice

        Gauges are made by VEI, and the gauge pod is 3D Design. Back in 2009 we worked with Neil at VEI to develop the orange read out to match the BMW OEM look.

        The G-Power is an air/air setup. The kit makes comparable HP numbers as any other kit available, however our dyno runs are inclusive of the 20 inch G-Power wheels, which definitely lowers the HP numbers.

        Since ASA and G-Power are owned under the same umbrella (Infinitas) they are able to develop the blower units from scratch to maximize the efficiency for each engine. For this reason, and the overall quality of the components, the kits are a little more costly than others.

        Thanks for this.

        I've seen dynos comparable to the other options BTW.
