Has anyone tried this out? This may sound crazy but here goes. Often times when it is extremely warm here in Southern CA, I have the a/c going. I know when the a/c is running it is robbing some hp from the engine's output. What if you can direct some of that cold air back into the removed tuba, causing 'real' cold air into the intakes. Won't this offset the lost in hp when the a/c is on?
