Last year we hit 490whp on pump gas on a built bottom end only on an APS TT kit running 14psi give or take. We did 530 whp on race gas 108 octane. Since then we upgraded to the 3.5" APS down pipes,3" exhaust, a set of JWT cams and a fully ported and polished mild race head set up from Headgames (the same guy that did the heads for Performance Motorsports on their 8 second race car)
Well, we started tunning and a conservative tune at 12psi on 93 octane, we hit 557whp and 540TQ...More to come..

 

You tha MAN!
can't wait to take a ride in that monster!
