I'm trying to decide which pulley size to get for my truck. I was wondering what size people are running with an LQ9 and how much boost you are making? Pulley boys offer a 3.1 thru 2.8. I'm currently running a 3.2 making about 4 lbs with the wrong cam. I plan on changing the cam but thought i'd try a smaller pulley first.

I would suggest getting a cam. The lingenfelter GT2-3 or the GT 7 are both great cams. then throw on a 2.8" pulley and you can make up to 9 psi.

Just wait till I get my new cam and Ill cut you a steal on my GT 2-3 . See how much that adds, and go from there IMO....

Get the right cam in there first. Really.

Go ahead and get the 2.8 pulley you'll wish you did in the long run.

Get a Reichard Racing Ultra Grip 2.8"..... can you say, no slip? Had one on my LQ4 and loved it. and swap the cam out while you're at it.

My MP122 has a 2.8" pulley. It's on an LQ4 with 243 heads. Might have a little more C/R than the LQ9. I get a whopping 7 to 8psi. Might be a little more if the weather ever cools off. If your exhaust is restrictive and your cam mild, you might get that much with a 112. I wouldn't expect much more. The good news is that you'll be well into boost with very little pressure from your right foot. Makes the truck feel like a vette. Matter of fact, mine will outrun a lot of them. Not too many mustangs stand a chance either

Yeah Ben, let me know when your ready to sell that cam. I guess I'll get the 2.8. I checked out the Reichard Racing site. I guess you have to call in an order with them. Pulley Boys gets $75 for their pulley any idea how much they go for from Reichard Racing?

RR pulleys will be a little more than the PB puleys, but well worth it, billet aluminum with machined groves that grip the belt.
