before going with the cog set-up i mean if slippage is minimal i may not need to change over to the cog set-up but i do want atleast 14-15psi up top
I think the standard pulley is 3.12 and the 9 lb pulley is 2.75 i am going for a 2.8 hi traction pulley which i asked vortech and said it is just sand blasted finish i have a 2.95 in there at the moment and im seeing 9lb up top so i will be happy with 10lp up top with the new pulley

not supprised you cant get an answer from them.. LOL they did not want to tell me anything when I started this either, But that sounds about right on your PSI, I was seeing 9 sometimes 10 up top on the 8PSI pulley. When all said and done I hope to see 13

Yea you have TP's tho. Less PSI, Still nice 3 PSI more is good, I'll see more than that becasue I upgraded the SC also I have stock cats. What is your WHP?

I fully understand i called stillen and they said they didnt know the pulley size which i find hard to believe. its not hard to measure one that is not on a car
