Why do you want to go to a 5%

I have a 5% currently on my 92 and am thinking about going up to a 10% since I now got bigger exhaust on and hopefully some day will be able to tune the darn thing.

can you run a 10% with no issues on a stock motor with ported manifolds and a larger exhaust WITHOUT issues?

What needs to go with the pulley? Spring tensioner, smaller belt...etc?

right now i'm running a 10% on my DD with stock motor and stock exhaust with out any problems

I currently am running 15% OD, and I'm wanting to drop down to just 10% because I'm having belt slip, and I dont want to take the chance of actually getting the belt to stay sturdy during a run/pass and not push too much boost and ACT's into the motor. Thats why I am wanting to trade my 10% SC pulley for a 5% SC pulley. I've alredy got a 5% JS.

5% SC or JS pulleys you can still run the stock belt. The 10% SC pulley, you need to get a shorter belt, and it never hurts to upgrade your tensioner springs. I dont know the belt number off hand, but SCP sell's them for right around 20 bucks if I recall correctly.

I'm still looking to sell/trade this pulley......any bites out there?

I think I might be interested. How do you want to work this out?
