I can never get a response from aspracing but can someone point me to the correct item on their website for the 4" pulley that fits the Comptech blower and also where can I get the appropriate belt for it. I want a little more boost than stock.
Thanks!

 

You should contact Comptech directly and discuss this with them. They used to supply (and may still do) the items you seek. I'm not positive on this but you "may" need a pulley smaller than a 4" to get 7 psi out of your system (you don't indicate if you have the aftercooler or not).

 

It's not listed on their site as they have to custom machine each pulley as requested. You must reasearch the correct diameter then tell them. There is a thread somewhere with a pulley=boost chart.

 

i have a 9 psi pulley and belt that i need to sell, if you are interested

 

i have a 4''... and was hitting 7psi..
