My buddy Craig'll probably see this post..he's run 11.19/124.8 (I think) with a stock TB and plenum...no powerplate, no 62 mm, no nuthin'. And that's with one of those useless little Eastern front mounts, and Flowmasters! Don't forget those..probably gave him 2 mph.
Well, my WE4 ran a 12.33@112.89 first pass this year, but the headgasket was already going and blew completely on the next pass. MY fault, not the cars! I got greedy with the boost and was at 28psi! I wasn't, nor was the car, ready for that much!
