A gain with the hood open can be lost with the hood closed due to carb to hood clearance.....

Lost 4hp with the hood down........Mine was engine dyno, my friend that lost the 4hp was on a wheel driven...

James,
At least 10 racers had them on at Indy in 2005. Bruce told me mine was fine and that he had no problem with it. I ran that same base for 3 more years and went through tear down at Indy in 2008 with the very same crew that is now trying to outlaw its use. This isn't a tech issue. It is a nhra issue. Glad I'm out of this mess.

All of this Air Cleaner Base BS... is just more confirmation of just how F***ed up things are... from Div. to Div. and from HQ in Glendora!

NHRA has let the S*** get so far outta control, that now, none of them even know what is correct or "Whats Accepted".

There are a number of threads on air cleaners in the tech section that explain it much better than I can.

Lew,

Ran the stock A/C assembly because of a hoop scoop, but always thought that OEM would mean what came on the car with that silly little tube with the exhaust stove top warmer snorkel assembly on most cars. I know nearly everyone runs either the flat open base or flat base with open element style. One of my guests yesterday was shocked upon seeing the 6" (?) dia. pipe and element on a new Cobra Jet.

Can anyone really runs 10's thru a 4 square inch hole? Guessing whatever they allow is ok as long as it gets "factored" into the equation...

Why run an air cleaner ? Im serious ? If your air cleaner and snorkel are creating a retriction, the rules say Air Cleaner Optional .... Why run one at all ? Temperature ? I mean ? They are race cars ,,,,, Am I missing something here ?

And I ask that in all honesty......what am I missing ?

That would be are you allowed to run a non stock base that improves air flow, not about running the stock air cleaner.

Are you running just the base? Or the base and air cleaner?

Gotcha, I knew I had to be missing something.

I was actually wondering if many or any run elements....I hadnt seen many....I have seen a few....

Tech was looking for air cleaner baseplates and stock seats at Brainerd last week. I guess this is an effort to move the class back to "stock", whatever that is.
