I dont think he knew what he ran in the 1/4. I believe that I among others offered him the opportunity to hand us our asses at the track. Funny he never showed up. Good tuning does make up for alot. High and low compression alike. After meeting Mugent3t4, I got the very strong impression that he didnt know crap about his own car and all the work was done at a shop by someone else. So I have a strong idea that he didnt know much about tuning.
I dont know about you, but I happen to have some experiance in turboing a non turbo car. Perhaps I am ignorant, then again maybe I am speaking from experiance.

Feel free to do your own thing, I have done mine and am very happy with the path that I have taken.
