Joe Simpson threw on that turbo and tuned it for the last few races of this season. He didnt spend the RIGHT amount of time on tuning it. He couldve gotten way more out of it! He made that power on a SHOT gt4294r. It was Cortney Greens turbo...and from what I heard Joe messed it up and thats why it wasnt making the power it shouldve been making.Originally Posted by B18c1Turboed
As far as the 42r...I wouldnt go off saying its over rated yet. I have seen a chart (will have one posted up of a non dual-ball bearing gt4294 soon) of a 4294r and it was hitting full boost (38psi) at 5500rpms. Now you can do the math...32psi=860whp...38psi=???.
ANYWAYS, Im not getting into a pissing match here...all I wanted to know was if the t76 was dual ball bearing...thats all.
P.S. Ill have a dyno posted up for you all soon...non dual BB 4294. Spools 300rpm later and 1k cheaper.![]()
