hey
dont forget to put ur car into 5th gear when pulling off the harmonic balancer pulley. steeda gave me messed up instructions, and they forgot to mention to put the car into 5th gear. i put pulleys on a 2000 GT, and that wasnt the case. looks to be with the 01 cobras. dunno. hope this helps. i didnt really feel a big difference with the performance, but at least it didnt cost a lot. i did see a GIANT difference when i installed the DENSECHARGER 100MM FULL FENDER TO THROTTLE BODY System. good upgrade, and it was only $162 with shipping. www.densecharger.com. awsome intake....simply awsome.
