[QUOTE="Snake Eyes, post: 2518571, member: 3410"] Well ZeroSpin had the 2.2L on his car when KB was doing the testing, but I thought he kept it. I just looked and he does have the 1.7 so I was wrong there but he did have it on the car for a little bit and as we all know Lidio ran the 2.2 on that Mach 1 for a while (and it would have been fine if he hadn't gotten greedy). And it is possible that we are both right because I haven't talked to Ken or Victor since the kit was released and they may have changed their story after all the problems you guys went through but when I talked to them they both assured me the 2.2 would be fine. Also let me rephrase 1.7 isn't maxed out and I shouldn't have put it that way. It is nearing the end of it's maximum effective operating range. Yes it is capable of more boost but if you look at the flow numbers that is what I was speaking of. As we all know not all boost is created equal and 13psi on a 4V cobra engine is not the same as 13psi on a 2V GT engine. So yes the 1.7 may be capable of generating a certain psi (on certain engines) but if there is very little resistance it will flow more with less back pressure and therefore less psi. Off topic but I really wish the automotive community would stop measuring boost in psi but rather cfm. Anyway I am not saying a 2.2L blower is perfectly safe far from it, but neither is the 1.7. Any blower that produces any boost on these engines is risky. The engine (rods and pistons) was simply not designed for a power adder. Can it be done, yes. Can it be done safely, yes.
