Inliners International Forums General Discussion Hi Performance Performance Enhancements for a Chevy 250

Something I just considered is if I add the turbo, I'm going to have to pay for premium gas aren't I? But can't I just add a gallon of denatured alcohol which is like 130-140 octane to my tank to raise it to where it needs to be? Because a gallon of denatured alcohol is only like $12. So just fill it near to the top with normal unleaded and then put in that gallon and I should be good to go right? Doesn't alcohol also decrease engine temp? Thanks
