Is there a way to tell over gas.... i know with alky doesnt it omit damp vapor out pipes?? If it were tuned properly is there a way you could run it it undetected?? We have a guy who is suspected of running alky at our local track with the guys running gas, Just wondering if its possible? I looked over his setup he has a psi big bowled carb (gold anodized)with P/J in it and a dual feed pingel. He told me he could run alky or gas with this carb and all he has to do is drain the gas and run alky.... I have never heard of such a thing.
