stock ct26 is good to 13-14psi, after that its just a hair dryer. ive heard that fcd isnt any good but thats just what ive heard.

had a guy an import tune shop tell me ma70's hit fuel cut at 14.7 psi.

EDIT: of detonation and preignition, here's another good article

there's another article i found in an aicraft magazine a while back that was REALLY good, but i can't find it yet :bah:

i dont think any stock car will make it to 14.7 psi, more like 11-13, 13 if your lucky. Mine fuel cut at 9.5 psi once. And the ct26 can be upgraded to about 400rwhp, but at that point its not going to last very long.
