I have a new ct-engineering s/c I want to bump the boost up to 10psi but cant seem to find witch pulley size I will need.

I called sos and they werent exactly sure what I would need to make 10psi on the 1220sl blower.
Plus they have been swamped with work and haven't been able to test fit their pulley on the new blower.

So my question is does anyone have a ct kit with a 1220sl blower running 10psi?
and if you do can you remember what size pulley and belt did you need and where did you get it from.

pre thanks for all responses

 

call comptech, see what they say. or call vortech, they will know for sure.

 

I work on a guys car out here with same setup. 3.8in made 11psi @ 9K. This should help

 

Where did you get the pulley from do you remember and what size belt did you use?

and was the car an ap1 or ap2?
