The 1.7 wont make 550rwhp unless you have serious heads on the car..Even with a stroker and stage 2 heads(foxlake)VT camsL/T's,Dr,gas ,14psi we only got 515rwhp but 570TQ

Now,the 2.2 is going to be another story.
We have a car here that is setup JUST like Kidds 663rwhp Vortech car.It has a new polished 1.7 on it.It will be on the dyno again next week.I'll post up results.But its already way short of the 663rqwhp kidd has.
