Well this thread is long overdue I guess. Single and double belt guys post away.
I had my stock SB 302 with TW heads, Holley2 intake and TFS#1 cam. Installed my Novi 1000 with the stock pullies and inlet pipe and C&L 76 and observed 5.5psi @6000rpms. I then went to a 4" inlet powerpipe and seen 7 psi with alot more torque. Then I installed the 8" crank pulley and observed 10-11 psi with even more torque.
I'll update the list when everyone puts in thier $.02, please add to this if you have good info to add.
1. HCI 302 with 3.5"/6.87",stock inlet=5.5psi@6000
2. HCI 302 with 3.5"/6.87" with 4" powerpipe=7psi@6000
3. HCI 302 with 3.5"/8" with 4" powerpipe=10psi@6000
