• Horsepower Freaks Stage 5 turbocharged E46 M3 cracks 1000 horsepower to the wheels

      Congratulations to Horsepower Freaks for continuing to raise the bar on the S54 platforms. Dyno numbers over 1000 horsepower are simply no joke and that level of power is difficult for many to even comprehend. The highest figure was hit at 29 psi as going above this amount of boost produced diminishing returns. They intend to dyno the car again with smaller wheels which should make an appreciable difference. It is likely at this point head flow limitations are starting to be hit and Chris at HPF hinted at the cam profile possibly being a liability. Regardless, we are seeing some amazing things out of the S54 that nobody would have ever thought were possible not too long ago.

        I'm pretty sure the only thing the HPF Shop car runs is pure 110 and no meth/etc..They should probably be using C17 or something for the Stage 5.

        Not sure I like that curve though. As boost comes on at 5k it becomes a monster though, must be a scary feeling Click here to enlarge

        Truly amazing accomplishment! That being said, the power delivery is not for me. Insane power nontheless.

        That's an insane amount of power going out in the last 3000rpms. Better make sure your intestinal tract is clean before flooring that thing.

        It almost looks (from the graph) that the car is not making much more power than stock until you are above 4-4.5k RPM... I like this car, I just don't know how I would like the top end power - it looks like (from the Acura vs This video) that every time he (HPF) shifts, he loses traction. Not sure how that can be handled... Looks like 2 issues - you are in a nutty power band every time you shift the car (if shifting from redline), and the other issue would be traction because of the first "issue" (really isn't an issue unless you want fast numbers?)I wonder how you plan to attack this? Really cool turbo kit - no doubt in my mind - but very narrow powerband in comparison with your other kits. I know you have your traction control system - how about a higher rear end gear? Not sure how much this would help, but would get rid of some of the RW torque... Just curious how you would handle this - car is making some crazy power, looks like it could be better utilized - just not sure how...Cheers.
