COG Pulley size, psi Question
Hi I have a Novi 2000 that i bought used with a cog set up. I only want to run about 8-9 psi, which the current cog set up is for 20 psi!!! I have a 78 tooth crank pulley what size cog blower pulley would i need to reach these numbers (8-9). Also this will be a bigger cog correct? Thanks Adam
You'll need a huge like 40 tooth upper probably.
Or you could get a small 72 tooth crank. Probably better to just spend ~$200 and get a 8 or 10 rib kit.
Again boost will depend on many factors like flowability, heads, cam, CU Inch, etc
351 "stockshort block": -Vortech T-trim (21 psi), Trick Flow Heads, Lunati Cam, Weldon fuel system, Lentech AOD., 3.55 gears, 27" Hoosier QTP's, 3500# with me
-545 rwhp
-10.02 @ 135mph---Is 9.99 to much to ask?:freaks:
-1.42-- 60'

what size are the current blower cogs you've got?
it's not hard finding a 40 tooth blower pulley rcdengineering could make one, its finding out if a belt is out there that will work with a 78/4x combination.
