i think if you go to a 2.76 which is the smallest pulley you will see a max of about 13.

I'm running 16 lb with a 2.81 upper and idler, and SCT Dyno tune. The car came with it, if I was doing it I would go with a 2.93 upper,the boost will stay up higher and longer in the rev range

no way, you will nto see that kind of boost out of an unported blower. to get there it would need a port and a bigger lower. i hit 522rwhp with a 2.93 upper and 4lb lower and that was at 14 lbs.

right now im at 15 lb with a 3.1 upper and a 8 lb lower should i keep it there until i get it ported?

what kind of numbers are you seeing. most i have ever seen out of any eaton was 17 with a 2.76- 6# combo.also you don't realize the power of that much boost without the port because the bloser can't flow enough air.

how are you guys reading your boost levels BTW, the stock gauge pegs at 10 psi and the overlay is not very accurate either.

i dont use the stock gauge i have an aftermarket one and it reads 15 with the 3.1-8# combo.

any idea on your numbers?
