Default Those w/ MMS Crank Pulley
Just wondering what size blower pulley your running and how much boost your seeing. Also, if you have heads, cam, intake and etc.

Thanks

That is with the MMS crank pulley, which is quite a bit larger in diameter, I'm not sure of the diameter off hand. Bob

MMS was 7.65 or something like that - it was big.

Bob, do you have any idea of the belt size for the 4.0" with the MMS pulley? I'll be putting it on this month.

Man, I would think you'd have more boost than that with a 3.7"
Could that be because you have a P-1SC??? I will be real similar to your setup this month. I'm looking for 11-12 psi.

Thanks for your response.

I was looking for around 10 psi but 8 is the most I see. Maybe I will get a D-1SC or F-1 here soon and see if I can get some better flow. When I ordered the pulleys they said that the combo would produce 10 psi. Oh well I am not complaining my times are fine for the hp output and weight of my car. I am satisfied for now.
