Topgunz - air to air upgrade

StillenZ84 · 06-19-2017, 06:35 PM

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.

Topgunz, any update on how your SC kit is going?

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?

Slower than I wanted (story of our lives). My summer has been crazy!

My 8psi pulley is silver and most that I have seen on the forum are silver (bare aluminum). The color is just a coating (anodizing) and should not effect performance. The "high traction" pulleys are often bead blasted for a more aggressive "bite" of the belt surface. I'm not sure how effective this treatment is over time.

One thing that I have noticed on the micro-v belts is that the ribs are fairly wide compared to the pulley groove. As the belt is put under tension the ribs are pulled into the grooves (standard V belt workings) and increase the surface area/traction. They do reach a limit when the force is greater than the traction. You gotta remember that a SC is drawing somewhere between 50 and 70 hp to create the boost we so love.

I didn't realize the 'high traction' pulleys were just bead blasted. Thought it was a coating for some reason. Heck I've got a bead blasting cabinet in the garage so can make all the high traction I want lol

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.

Yeah. Different A2A kit maybe? lol.

^^^What he said.

It's not difficult. you can sand it and get some paint to make it look almost stock. I don't have a picture, but I used Rustoleum Gloss black, I believe, and it looks the same. I also used a Dremmel with the metal cutting wheel. It took 3 wheels to do the job lol.
