    • VF-Engineering VF650 supercharged E92 M3 versus a Hennessey tuned Cadillac CTS-V

      This video comparison comes to us from Brazil courtesy of Full Power Magazine. These two cars grace the cover of their August issue. The M3 has a VF650 supercharger kit and we have seen the weaker VF620 put down 521 wheel horsepower on 91 octane. The exact modifications on the CTS-V are not given but it is stated to have around 650 horsepower as well with Hennessey upgrades so likely just a tune, pulley, and exhaust upgrade.

      The numbers in the video are given in CV (cheval vapeur) units which is a French unit of power measure that closely correlate with horsepower units. 1 CV is .986 horsepower. On paper according to the magazine the cars have similar horsepower. In practice, the M3 dusts the CTS-V rather easily. Kind of surprising to see the M3 pull this hard on a tuned CTS-V which is why we would like to have the exact specs the Caddy.

      We also do not know which transmission the M3 has but we assume the dual clutch trans.

        Nice music. Too much dub stuff in it though. Needs a better remix.

        It's the same unit as PS but it's translated in French. In Italian it's CV (Cavalli) and HK in Swedish.

        It ran 11.7@122 on their track in the back yard
        please tell me that wasnt an 11.7@122 run in that video...it looked much more than that....which means ERMs ESS625 is way more powerful

        I think it's the specs and results of the CTS not the M3.

        its a VF650 car 7 .5 psi

        lets not forget that nismo370 @ "6psi" beat a ctvs with over 650hp @5k rpms lighting the tires up on the dyno, by 2-3 cars. the motors make power, but the cars are heavy..

        Yeah I remember that he did destroy that V the was before he got his boost controller.

        they actually drop the boost in the V and i bet didnt upgrade the pulley to compensate...a V with headers and the right pulley can do 125-126 all day

        Dropping the boost just lowers the backpressure the car should breathe more freely and make more power.

        it will but wont make more power unless the pulley size is changed to compensate....trust me...happened to plenty Vs....you dont go headers in that car until you are ready to pulley up

        @Sticky you might want to update the OP, if you watch the video again it shows the m3 interior with a DCT.

        Argh, I figured it was a DCT. I'll just leave it alone, people can read the comments.

        looked like the V would need another 100hp to complete again in this race, it not in the same league at its current state

        Not always, just creates a lot more heat soak on a road course.

        If the boost drops it reduced back-pressure it clearly is making a difference... and as mentioned more power with less heat. You don't have to push the blower as hard.
