Topgunz - air to air upgrade

StillenZ84

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 .

Did you do a straight swap and retune or was it done all at the same time as when you put the A2A kit on?

Nah....I got the 9psi pulley swap early on when I first purchased and installed my Stillen kit a few years ago....when the Air 2 Air Kit was nothing more than a discussion of this forum....It's been tuned by Seb since then with all the upgrades since that time...including the A2A...car is still producing 9~9.5 psi right now but feels sooooo much better on the A2A kit. I'm getting belt slip.which Never happened on the the Stillen Kit....which is why I'm gonna install the Idler Pulley Kit from TBatt

You'd think it would not be a problem considering the extra room vs the OEM fascia but it does incorporate a different windshield washer fluid reservoir so who knows. Just covering all the bases.
