I picked up 1-2 tenths in et and approx 2-3mph by sealing the scoop to the carb. But figure in that I also upped the jetting 2 sizes at the same time in anticipation of more air. I put the air cleaner on for a pass & dropped 2mph, my air cleaner is the small round 9"x2". I'm in the process of fabricating a filter housing for installing a 9" xtreme flow K&N filter in there, I'm a firm believer in the K&N after experimenting with it in my modified Dodge Cummins dualie. I'm not thrilled about running no filter at the track.
