[ModularSpeed]

Bill is trying to tell you, many years ago.....he amazingly discovered something.

He came to the conclusion that no manufacturers made an underdrive crank pulley (dampener) for a Mach 1.

He then found out that Paul S at PHP used a set on a Mach 1.....and had engine problems. I actually think I remember Paul doing a test on a Mach 1 years ago....running like high 11's with a couple bolt ons and some slicky poos. Maybe it was in a magazine? Didnt he use March pulleys on that car? I dont remember. I know they only gained a couple horse....but he tested it after he also installed gears and built rear I think.

Anyhow, I have seen low compression on a low mileage stock 4V, I have seen broken pistons in a stock tuned stock modular, I have seen a handful of people break the oil pump with stock dampener/stock flywheel-clutch.

It is a risk we take.....and I have pretty good odds I guess!
