I have a basicly stock 03 Cobra and I'd like to try a little road racing. The only upgrades I have are an upper pulley, SFC's, and a coilover kit (using stock struts). I know cooling can be a big issue so my main concern is my upper pulley. Is a 2.8" upper pulley too much for a track event? Should I put a larger pulley on for track days to help with heat soak? Anything else you guys recommend? I'll only be doing this once or twice a year so I don't want to go way over the top, just the basic stuff.

Thanks in advance for the help!
