Ouch, the aftercooler isn't doing much for you at those boost levels. You should pulley your blower so you see 10+ lbs of boost.

I'm not sure what diameter pulley is suppose to give what psi with your setup. If 3.33 is suppose to give 10-11 lbs of boost but you're only seeing 6-7 right now, it sounds like you have some serious belt slip going on.

byron said the reason why i'm only getting about7 psi is because when i got the aftercooler i didnt put the pulley that it came with (3.33)i left the stock one which is 6-8lbs, and because the aftercooler makes you loose like 1-2 psi thats why i'm seeing 6-7psi...so i put the 3.33 which is i think 10-11psi , then i should see 9-10psi because of the aftercooler, correct?

Why not change the crank pully for a bigger one?? If he goes too small on the blower pulley he'll end up with more slippage.

Sorry, I thought you had already installed the 3.33 pulley and were only seeing 6-7 psi with it. I agree with the above post... it should make about 400 rwhp given 10-11 lbs of aftercooled boost ![[patriot]](graemlins/patriot.gif)
