On a car with a factory flat hood, most use something like a large dia. Moroso or one of the high flow, spun aluminum models that are prevalent in roundy-round racing. If a heads-up race comes up, off comes the top and element, leaving just the base in place. My .02.

I thought I had to run the factory Air Cleaner but a aftermarket Filter.

Re: Air Cleaner Question
 

NHRA does not allow those and they have apparently been cracking down on them. Why I don't know, but thats what has been reported (even in SS they have said no).

You can run a factory canister with or without the lid or nothing at all. You can run the "standard" aftermarket Moroso style. If you had a ram-air system you have to run the OEM components to get the air from here-to-there.

You can cut them but not weld or glue...

Re: Air Cleaner Question
 

You can use the spun circle track air cleaner..
You are not allowed the spacers provided with the air cleaner..
Tech man has to be able to put a straight edge across the top of air cleaner and be able To touch carb air horn ..

I believe Dusty runs the spun circle track air cleaner James is talking about here, or am I wrong? Jim

Re: Air Cleaner Question
 

Its all good been running it for quite a while
Micheal had a problem at Chicago Nat last year
Got to Englishtown next race they made a ruling on it

Re: Air Cleaner Question
 

Wish I'd known they allowed them again. Went and bought the GM open base after they told us we couldn't use them anymore. Nice to know they will let us run them again.

Can you tell me where this is printed. I would like to see it. Thanks.

Re: Air Cleaner Question
 

I have seen these on a number of division one cars. I can't find one like the one on Jim B.'s car though. Looks like it could be worth something.

Not trying to rob this topic but,,
Speaking of air cleaners, Does anyone have a bottom to fit a 4-gc carb ?

Or any ideas for performance using the air cleaners in stock?

Re: Air Cleaner Question
 

Keep in mind, there are a variety of spun and stamped aluminum bases available. The differences in profile can be significant. There are bases that perform well and others that create issues. The steel base without radius that includes areas to accommodate the needle and seat/float adjuster is one example.

We test these bases using flow rates to 1200 SCFM each day. Filter outlet diffusion is very important. Pay attention to the radius design of the rise and be cognizant of the fact that a drop base with a lid creates velocity concerns, especially with a short filter.

There are ways to maximize this profile and provide a consistent delivery to the boosters.
