im interested in buying a 7-8 psi boost for the comptech sc

 

What size is that?

 

I am pretty sure the SC with the aftercooler runs 7 psi with the stock pulley.

 

My Comptech SC w/o AC runs 5.4psi stock. With the AC it would be less.

 

i dont know what size it would be thats why i have this up to buy it

 

with no aftercooler my 4.375 pulley was about 6.8lbs and another member had a 4.25 with about 7.4lbs. with the drop put in with the aftercooler i think a 4 or 4.125 should put you in the low 7lbs boost range.

I'm interested in the 4 or 4.125 pulley. I'm finally getting my AC soon. I'm currently running the 4.375 without AC.

I've got a 4 I would consider swapping for a 4.125 or 4.375 maybe.

 

Is there a listing somewhere of the Comptech and different size pulleys and the boost made?
