Do you know how much lighter than a stock?
Is it gona be smaller in diameter? by how much?
If smaller will we have to use a smaller belt?
You have any ballpark idea on hp gains?
Thnks
The stock pulley is just over 5 lbs. The underdrive pulley is just over 1 lb. It is also roughly 15% smaller. I do not believe you'll have to replace the belt, but I'm not 100% sure on that. Rough estimate for hp gains is 2-4 hp.
