Trying to determine if I can use either of the pulleys that came with the used Procharger kit I just bought. I'd like to stay under 8 or 9psi since it's a stock internal motor...but I'd like to make at least 6psi. I have a 6" crank pulley, and I have a 4.38 and a 3.85 blower pulley...with the mods in my sig (mainly just full exhaust and Shaner S3 TB), how much boost can I expect to make with those pulleys?

With a D-1SC 6 rib kit, a 4.00 pulley would get you around 7 psi with your headers and exhaust system. The 3.85 should be close, I'd use it. Bob

Awesome, thanks Bob!
