Which pulley?
Concerned about intake air temps... my car will be a street car only. With that in mind what percentage lower pulley should I go with? ATI or IW? I'm thinking ATI 15% since IW only makes 9 and 18 from what it looks like. Thoughts?

Before I changed to a Whipple on my build my plan was the ATI damper and 15% overdrive pulley. 9% is too small 18% too big IMO. 15% is the ticket to not overspinning and causing a heat pump.

I went with 15% lower for all of the aforementioned reasons. Also what Sam at Advanced Modern Performance recomended. Anything more than that and heat/overspinning an issue, and they have done a lot of Z06 and CTS-V packages.

Is it possible to run a 15% lower pulley on the stock tune?

Does anyone have a part number for the ATI 15% pulley? On ATI site it is hard to read and does not have one listed for 15% ( I could have been looking in the wrong section) Also, Where to purchase?
