A 3.4 SC pulley is good for up to a possible 25 - 30 hp. See link below:

Other companies are ZZPerformance and South Florida Pulley. If you plan on changing pulleys frequently, the modular system is best.

Also you'll need to drop down at least one range colder on the spark plugs just in case to counter any possible knock retard (KR).

No changes to lubrication but it would be a good idea to put in new supercharger oil especially if it's old or never been done. To cut down on any possible belt slippage at high rpms it's highly recommended to switch to a GoodYear Gatorback SC belt of the proper size.

Other than that it's plug n play.

I'm looking at a 3.4" pulley myself(of course it will come after CAI, and a cat-back)...

I can "hang" with Gt mustangs now, I want to embarrass them with my 4-door grocery getter ;)
