Smaller pully on V1 Vortech
Hey,
Has anyone had success with turning up the boost on older Vortech V1 (a trim) by usnig a 3.33, or 3.25 pully??
Or does that end up causing problems??
I'm pushing like 7psi right now, Wanna goto like 10.

Yeah, I bought a 3.33 when I had my A-Trim and the original 6 rib pullies. Got around 9 or 10lbs.
I wouln't go smaller then that though. The belt slipped enough with the 3.33. I had to really keep the belt tight.
