underdrive pulley
 

i'm thinking about getting the unorthodox racing underdrive pulley. it's not hard to change is it? is it worth getting? how much more hp do u think i will get out of it if i get it?

I've had my '89 n/a for 3 years. I've researched the hell outa power up grades. I won't do the under drive pully because the crankshaft dampening would be lost. The main bearings will wear out much sooner. Only do this if you are drag racing, and don't mind tearing down the motor often.

i dont plan on drag racing and i don't really want to tear down my engine often

thanks for telling me before i screwed up my engine
