Ok so there isn't an ATI stock size wet sump application pulley? Just one pulley for wet sump applications, and it's a 4% underdrive pulley that is approx 3/8" smaller diameter than the stock pulley.

For dry sump applications, they have stock size and 15% underdrive options.

So what belt did you use? Stock size or slightly smaller?
