I am using the novi 1200 that came with there kit for a small block mopar.

Novi 1200 isn't the largest paxton s/c out there but it should put out enough to build you more than 4psi. You might want to do some reading and find out what the max impellor rpm of your s/c is and do the math to find out what's the max rpm you're spinning yours to with your current pulleys. Who knows, you might be able to gear the s/c a lot further...

Thanks i will check that out. I also have a lead on a NOVI 2000.

Thought i would post some times from this weekend.I know its been a while but have two small kids that take up most off my time. Anyway ran the car this weekend at lebanon valley on the motor. Best time was 12.02 112 mph. Then sunday went to my hometown dragstrip and put a 150 hp NOS plate on it. Car went 10.64 126. I did sell the novi 1200 i had and bought a vortech V-24 but have not had time to finish it yet.Winter project.
