Stock rev box, gearing, and 22" tires. Top speed 55mph. Same as stock. Not limited by power but gearing and rev limit.

You'll get there faster though.

If you want more top speed.. you need a higher rev limit, or taller gearing. (larger front sprocket, or smaller rear sprocket.)

my pistons are shot, what ones would u get?

You only have 1 piston. ;)

I'm running a weisco 11:1. Never had any problems with it.

However... if your piston is shot on an 03, on a 300ex.. I'd be looking for why it's damaged. It's not normal for a 300ex piston/rings to go out that fast.
