I just had a crazy idea which certainly would add an interesting twist to the competition...

What is one thing that every STREET car has or should have?

An air cleaner!

What if every competitor was required to cruise & race with a street type air filter in place? Since a high HP might see a restriction of the air cleaner, this rule may tighten up the spread of ET's and somewhat limit how fast the quickest cars can really go.

The rule could state that a round size of say 14" diameter by say 4" high is the max size (no K&N filter lids). If a car is fuel injected with a factory style air box or aftermarket ram air, a filter with the same square inches of filter material could be used. And of course, tech would have to ensure that the filters were tightly sealed to the carb/air inlet with no air bypass holes.

Kinda a silly idea, but sure would make it a tuners race (obviously have to be tuned in before showing up) and the highest powered car would have it's hands full tuning with limited air flow input.
