Hello, I was wondering if it is worth it to buy a RK sport under drive pulley, and If I will notice any significant changes. I race a 95 2.2L cav on a half mile oval with just bolt ons and want to see if its even worth to buy, or if I should just spend the money on gas tires etc.

Thanks,

Jo Brown

Here's the one I use. You will notice a slight gain where you'll need it most, at the upper rpm. You're not using a big sound system (at least I hope not! ), so keeping the battery charged won't be a problem.

I know I have a 2.4 but I had an underdrive pulley and a system, not huge only 500 watts, and it slowly killed my battery. Luckily it was still under warranty. I would imagine no system and you would be fine as said above.

Nice I guess I'll order that in soon . Thanks for the help Mad Jack.

This may be a noob question...
but when you put a small pulley on alt/crank/etc dont you need to find a custom belt?
