So i finally dynoed my car and it made 548rwhp!
While im happy with that i thought i was making close to 15*boost. It only showed 11.79 * on the dynojet.

My current setup is :
Vortech s-trim w/ 928 motorsports impeller.
(Good to 60000)
7" asp crank pulley
2.75 blowerpulley
Fmic

I want to go to a 2.5 blower pulley, but im afraid of belt slip. Anybody running that setup?
Thanks
