Yeah, after a pulley, intake, injectors, and a tune, it's pretty much over though, haha. There's a big debate about putting a 19% pulley on a stock car because it'll end up spinning the SC too fast and possibly burn out both the SC and the water pump, so 15% is where it's at. It'll make a great gift considering they can be had for less than $150.
