Topgunz - air to air upgrade

I agree! It totally wakes up the supercharger sound!

I also would like to point out that even though you have a 6 rib belt vs. 7 you are still getting like 85% more grip.

6 ribs vs 7 = 15% less.... 2" of wrap vs now 4" = 100% more. 85/100 = 85% more grip!!

Do you plan on doing any tests to see how much psi you gain from it? Did you have a solid baseline before the install? It wouldnt be too hard to throw the old belt on and just bypass this if you didnt.

Did a before and after run and gained 1 psi at around 6500 rpms. May have gained more but ran out of room on the road. I need to get on that dyno. I need to get ahold of Seb and arrange a time to do it. Been real busy with getting ready to move and work.

NICE!!! A full psi is 100% worth it.. and more. I figured it would be a definite gain as after the 20 dyno pulls, and a half can of some pretty amazing belt grip I figured that was about what you would gain from getting more grip on that belt. If i had time to do this i would have, glad i could help encourage the project. Great job!

And if anyone is thinking "what about cog belts on the supercharger side". DO NOT TRY THIS. I went through 2 belts and 2 weeks of headaches. It will never be reliable enough to run. The setup back there just wont allow the clearances you need. The extra pulley is where we really need to put the grip down anyway. However, i will say the sound that came out of the cog setup was very intoxicating to say the least. Reminded me of my old positive displacement eaton blower on my 350Z. Wish i could have gotten it to work.

Yeah after installing the blower I always thought it was crazy how there was low grip on the serpentine side. This is the way it should have been.

Just finished up digging through the Gates belt sizes and found a 8 rib belt that will work with the additional idler pulley that Pauly Z is using. Now to figure out how to remove one rib so that it matches the 7 rib serpentine. The 8 rib is K081088. I wonder what the minimum order to have a custom made belt is. I'm pretty sure that they make these as drums and simply slice them to the correct width. The printed label kind of gives that away.

Does anyone know what size idler pulley he used? What about using the SC idler pulley? Its off now because I went to a larger idler because of the smaller SC pulley.
