I'm a bit (key word BIT) skeptical about these numbers. First off, Akra with HFC is more restrictive than test pipes. Second the intake ram effects are a great idea, but I don't think they will work to their full potential during dynos. Going 100+km/h, yes, maybe, but not on a dyno. Cams can add quite a bit of power if tuned properly. So given the fact that they claim 500 crank hp, this would translate to 414whp and 290wtq assuming 18% loss. Perhaps if they shifted the powerband higher in the RPMs using cams, then yes. But this is all top end.
