Qwickchange 3.4" Pulley
On 9/27/2003, Allen (co-founder of the Central PA Club Grand Prix) and I swapped out my stock 3.8" press-on pulley with a Pulley Boys Qwikchange Modular Pulley System (MPS). Allen fortunately had a puller and the time to help me remove and install the 3.4" pulley. It took us about 2 hours (1 hour to pull off the old, and 1 hour to press on the MPS hub). I also took the opportunity to install a new Gatorback Supercharger Pulley Belt. Horsepower gains are somewhere between 25-30 HP which puts me at about 280-285 HP now.....which is 40-45 above a stock GTP. Sleeper? I think so!
