does anyone know the if these numbers are crank or wheel hp? it confuses me because it states the turbo is good until 500hp but the baseline and after dynos they provided were 229 and 309. is this on a sti or reg. wrx? does anyone know the numbers on an sti? http://www.gruppe-s.com/Subaru/PowerPackage3.htm
I don't think the "magical" Helix RR500 turbo has made a debut yet. IMO, I'd search around for another kit.
So it basically made 80 more wheel hp on the dyno...but that was also going to a front mount and other stuff...I have seen the stock 39 push close to that with good tune and upping the boost. Maybe thier tuner is just not quite as good as the Seigel!
Bump an old thread. I'm investigating this turbo as well. You guys have to remember Gruppe-S dyno is the Mustang dyno. Their numbers are insanely low compared to others. 300 hp on their dyno is the equivalent of about 375 on Topspeed's or SOG's dynos. Also this was done on 91 octane tractor piss for the pump only tunes.
