Topgunz - air to air upgrade

I've got the regular 8psi pulley in the front side of the jackshaft as well. It's tight for sure. In fact have to be careful, I got just a little bit of water on the area doing some cleaning the other day and it was enough that it kicked the belt right off.

Was going to grab a 9psi pulley, just to clarify it sounds like the Vortech one goes in the SC backside of the jackshaft where the Stillen one goes on the front. Correct? I hadn't contemplated there would be a difference but stands to reason there is I suppose.

I actually had one before and wasn't going to use it so I sold it. Which of course I now regret.

ChaseZ, You are correct. The Stillen 9lb pulley replace the silver 8psi pulley (jackshaft) on the serpentine belt side. See attachment.

Does anyone know where you can get a Stillen 9lb pulley?
conceptzperformance.com just ran out.

Stillen 9lb pulley is 2.75" 7 ribs from what i have seen on other forums. Correct me if i am wrong.

So I would need to find a similar pulley. Maybe from Vortech. Let me know if anyone finds one please. I will keep looking.

Would def check the sizes. My silver pulley was the 8 psi and measured 3.12. My 9 psi was black and measured 2.75 or around there. I went from 8.5 psi with the 8 psi pulley to a little over 10 with the 9 psi.

Well my boost did increase between the 2 pulleys...with the Bluish pulley I was pushing about 7.8 psi.... just shy of 8psi.....Stillen said this was caused by me running TP'S and having no cats (back pressure theory) so they sent me the 9b pulley and my car has been pushing 9~9psi on it .
