The bad thing, is your question coming from you is like us asking Neal Armstrong how you set the thrust on a rocket motor. We wouldn't even know what the answer meant. Looks to me like your position on your racecar is you don't know anything about engines so the answer is uncomprehendable. There's nothing wrong with you being that ignorant on engines, but you should be a little more humble. Your question was answered correctly many times. Lighten up maybe you'll learn something.
