Hey fellas, a few questions, I have a v-1 s trim on my car, makes 10-12lbs. of boost depending on how cool it is outside, I also have a afm boost pipe and aftercooler, question is, what is the stock size pulley on s-trims, s trim was on the car when I bought it, also, I have an 8" crank pulley, but wont fit the car, 4 core aluminum radiator and an electric fan, so I am looking to get a different blower pulley, no room with the electric fan, so would a 3" pulley give me much of a gain?
Thanks

I think the stock pulley is a 3.33 or just a tad larger,, A 3" pulley will definitely give you more boost,, being that you have a aftercooler, I would even consider going with a 2.95 or even a 2.75.. With a 2.95 on my S-trim I am seeing 10-11lbs of boost at 5800 feet... at sea level, i would probably be seeing about 14-15,,,, Lee

Lee, do you have any belt slippage with that pulley?
Thanks for the response, Greg
