what is the secret in making all the high torque.what kind of lower/upper pulley to make 600 pounds of torque.carl and larry or anybody else chime in.thanks

21 psi race gas track tune and 17 psi street tune.

3 inch upper with 4 # lower = around 21 psi
3.5 inch upper with 4# lower around 17psi

I have low torque numbers because I did not use a 4# lower and had belt slip from such a small upper. The hp numbers are on 17.5 psi. I bought a 4# lower and am in the process of retuning it all.

22 psi on 93? is that even safe? I thought if you tried doing 19 lbs on 93 you were pushing your block to the limits. I have never heard someon runnig tha much boost on 93 octane. Who is your tuner?

22psi ,thats all everbody runs on the east coast . i know of at least 30 cars running my same setup with narry an issue:D Chris doesnt tune to the edge, he is very safe . i had my whipple installed 2 yrs ago at around 18,000 miles and it s at 28,000 miles with no issues , i drive my car hard alot and it has over 100 passes on it and it still runs as good as the day i bought it. had it dynoed just before i moved out here to be sure everything was still in order and a/f was dead on and it actually made a few more HP than before. as long as your tune is good, you stay on top of oil , and plug changes, and know how to drive you will be fine

Ill have to get in touch with you later this summer. I plan on getting a whipple and i just wanted to run 19lbs. Maybe i can get a look at your dyno charts and get a list of your mods to check it out. thanks for the info.
