Roush to anyone who has the upgraded 66mm pulley

[mat82284]

I am trying to find out what the normal psi range is on this supercharger. I have the series 1 with the chicane pulley 66mm and i only see 8psi but i think it might hit 9 just not to sure. i heard that most get 10-12 psi is this true? or am i about right for psi? Well i figured a poll could help out me and future posters since i couldn't find anything on this.

Also i upgraded my alternator to a 200amp and it came with a bigger pulley, i was going to get a smaller belt but this pulley made up for the dip in the supercharger one, so the stock saleen one fits extremely snug took effort to squeeze it on. Could the bigger pulley cause me to loose boost?

Everything I've seen about the Chicane pulley was in the 9-10psi range (3-4 over the regular Series I). But I think it can/will vary car to car though.

That said, I'm toying with the idea of getting one myself.

The Chicane 66mm pulley will give you 8-9lbs of boost. That's what I'm running.

I have seen it up to around 10/11 on a really really cold day...but that's an anomaly. You're in the normal range.
