Default What's the largest crank pulley that will fit?

I had been thinking about going with a larger crank pulley to make more boost. My plan was to go up to 8.5" because with a 3" blower pulley I would be maxing out the blower. Here's the question, will it fit? I was looking at the space between the stock pulley and the water pump pulley and I can't see how it would. I'm not even sure an 8" will fit.

Thoughts?

That won't solve your belt slip problems, though

Try a better tensioner and a Reichard Racing ultra grip pulley.

I running the Gates tensioner with a 2.9 Reichard Racing pulley with no belt slip or belt dust and have seen over 13psi @6100rpm on my truck, specs in sig.

nope, but running 8 rib belt might. got a quote today from ATI to make me a cover for my superdamper. Cheaper than the IW version and i don't have to totally remove it from the crank. i'm down with that


BUT, my original question was, will 8.5" fit or is 8" the max?
