which pulley?? So I have searched and searched, and I haven't found what I am looking for.
I have a stock ls1, only mods are the ls6 intake, and full exhaust with long tubes. and a D1SC
With the pulley thats on it, I am only pushing 4.5 pounds. and am just under the 500 horse mark, it made 498.
I want to get it to 10 pounds, and I can't find what size pulley i should be looking for.
thanks in advance to all of those who help.
its a 2000 Z/28 M6

Finding out what you currently have is important. Also are you using the twin intercoolers, if so 3.5” or 4.5” thick? The plumbing and intercooler options used can have an effect on how much air makes it to the engine. Just switching from 3.5” twins to 4.5” will gain you a pound of boost if not more as they can flow more air through them.
Like Ls1RedZ stated a 4.25" pulley on the head unit should get you 10psi on a mostly stock engine like yours with a D1SC head unit and the standard Procharger crank pulley size (7.625") anything substantially less would be an indication of a problem/leak in the intake plumbing.
