I actually found a Nascar air cleaner base and hacked it up to a 69 camaro cowl air cleaner outer ring and bolted it together. Looked somewhat factory for the 69 camaro once the rubber seal and ring were mated to it. Who knows if it worked, as I never got that far into testing it.

If there's any question about your base then pull it off when you exit the track and before you get to fuel check. From what I've seen fuel check is usually some distance from the track exit. I see people that win A LOT get out of their vehicles and take wind readings after every run 50 feet from the track exit ever. Why not then just pop the hood and pitch it in the trunk.
