We had a 03 Cobra down with a Kenne Bell and the first pull we saw 24psi, but not for long- look at this, it's crazy

Kenne Bell 2.2 no real numbers, but just that first hit I think it saw about 600tq, it was over before it started

there was somewhere I was reading about the pulleys (stock) being bad. Can't remember where I saw it at. That is insane though:eek:

They do not last long where you start upgrading, The bearings will always fail when you start spinning them fast than they where intended.
