Performance, Brainstorming & Tuning Talk about modifications, or anything else associated with performance enhancements. Have a new idea for performance/reliability? Post it here. No idea is stupid! (please use Detailing and Appearance for cosmetic ideas)

Time to say goodbye to the freakishly fast GP GT....

Updates would be:

Ran 13.22 @ 102, still with no tuning, on pump gas and a 3.4 pulley. This was in very bad race weather (like 85ish IIRC, wtih HIGH humidity). With some tuning I think I could've probably dropped the pulley to a 3.3" on pump gas and ran a 3.2 or so on race gas.

Since then I added a Stage 2 ZZP I/C and also some pacesetters. I'm running a 3.0 pulley with 20.5 degrees timing daily with no tuning and it runs very strong. The trans is shifting awesome after the refresh I just got, doesn't seem to slip anywhere, I actually think I'm going to need to modify some shift points a little now. I'm going to drop to a 2.9" pulley tommarrow and begin tuning.
