Which cam with an ATI Procharger? I have an '02 Corvette with an ATI Procharger (7psi). Last week I ran the car at the track and I had a best run of 12.05@115.
Now, I am looking to complete the car with LT headers and a cam. . .which cam would you guys recommend with a supercharger?

Re: Which cam with an ATI Procharger? TTT want to know also. If I were to go with a FI setup would the Hotcam help or hurt me compared to the stock cam? Just a quick little question.

Re: Which cam with an ATI Procharger? What do you rev your engine to? You need to pick a cam that has a power band in the range of your intended engine RPMs. I used the Vortech supercharger impeller calculator to find the right engine RPMs to spin the blower to. In my case, I'm revving to 6400RPMs, so then I picked a cam that peaked right about there. The Comp Cams 218/224 .527/.534 seemed to be the perfect fit. For a blower, you'll want a little more exhaust duration and lift than on the intake side, and people have seen good results by sticking to a 114 LSA.
With a cam and headers, your car should fly. I know mine does.

Re: Which cam with an ATI Procharger? Crunch,
What cam you running? BTW, MMS has a couple nice looking blower cams that are on a 115lsa. I'm going to call MMS on monday and ask more about them. I like the 218/228 .558 .558 115 lsa version. I have a 216/220 114lsa cam now. But the 115lsa cam won't bleed off as much boost so it should make more cylinder pressure which means more power.
