hello all. My bro down @ big wood racing just got finished building an 2008 Saleen into an Extreme version. The stock saleen made 283rwhp and 309rwtq SAE. They added an saleen extreme s/c kit, BBK shorty headers, BBK catted x-pipe, and a duel ford gt fuel pump. The tune on the car was the mail in tune from saleen. The car made 420rwhp and I forget the tq it made. The car ran very rich. video link below. http://videos.streetfire.net/video/Saleen-Extreme-Build_164650.htm enjoy
well the factory saleen extreme has the pj 5.0 engine(400hpfw) plus the same supercharger that was on this car and that combo makes 600hp fw. This car is making around 500 flywheel hp, about what a stock gt 500 makes.
