I brought my car to the dyno today. I did three pulls each 10 minutes apart from each other. Engine temp was the same in them all but I think it ran better the warmer it got.

First run was air cleaner on, hood open. Second run was air cleaner off, hood open. Third run was hood closed & air cleaner on.

Want to guess which one is best? Air cleaner on with hood closed was best. It was 5 HP more than air cleaner off with hood open.

So even if the car started running better with each run as it got fully heat soaked, it's safe to say that using the air cleaner did not hurt performance at all. It actually helped.

Oh, and look how sweet the curves are!
