What air cleaner base is NHRA Legal?
 

Michael is racing my car in Chicago this weekend.
The air cleaner in question is a nice aluminum base cirlce track one.
I know alot of racers use this.
After 1st run was told to take it off,WTF been using it for 4 yrs.
Ive seen more aggresive lookng ones than mine.
Beware

The way I read it is OE for combo. They have been letting this slide for a long time. I was wondering when someone would complain. You know that is what happened. I also have been using the same one you use.

Re: What air cleaner base is NHRA Legal?
 

We've been told that an OEM or OEM-style air cleaner can be used, which means a K&N base is OK, but not the stub-stack. I'll venture a guess that a custom molded base doesn't fit some folks interpretation of what an "OEM" air cleaner should look like. There are a number of threads on air cleaners in the tech section that explain it much better than I can.

Its just a chicken ***** call . they don't have anything better
to do. How much power can a stock type looking base help.
Any dyno test on this subject???????

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.

Re: What air cleaner base is NHRA Legal?
 

James, I think that tech guy that's bitchin' about your air filter base out in Chicago is a friend of Drooze's....You know, maybe it's payback time from you cranking on him and his efforts all the time.....ROFLMAO.....:D Just kidding, James....hope he does well w/your car out there....WJ

Re: What air cleaner base is NHRA Legal?
 

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.

Re: What air cleaner base is NHRA Legal?
 

Thank guys
I understand about stock type .
Micheal was told a K&N or moroso or stock style.
I here you it had to a crybaby..But Rules Is Rules
WJ... Drools may run this site but Tech picks on everyone evenly..
Wonder way the geunius is GIVING UP...

Re: What air cleaner base is NHRA Legal?
 

If it was not a crazy 16" air cleaner base or as what was said a custom made carbon fiber I don't see what is wrong with it? Just my worthless $.02. I (NHRA) would be more concerned about the underated cars that are not being looked at vs this.

Re: What air cleaner base is NHRA Legal?
 

[QUOTE=Wade_Owens;190557]Was that dyno result with the hood closed or open.
A gain with the hood open can be lost with the hood closed due to carb to hood clearance.....

Re: What air cleaner base is NHRA Legal?
 

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".

Re: What air cleaner base is NHRA Legal?
 

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...

Re: What air cleaner base is NHRA Legal?
 

It saddens me to se continued misreading of my posts....

Giving up ? Were going to add 2 cars to the game.....In addition to replacing the DP if it sells, if not well still add the other 2, only 1 will track this year if the DP dosent sell however.

Do you really believe the "inventive" interpretation of things you "think" you read ? It explicitly said I wasnt giving up, rather going in deeper........Do you want people to actually believe what you say when you outright put blatant lies to this board ? Do you really think people are that gulliable ?

James, my, you cant even leave me out of your own posts......

With so much bitterness, is it something personal , did I date your daughter, or niece or something ? If so I am sorry, they were forgettable and a I apologize.

James, Incorrect about something ? From the air you purport you are without error, hence this must be the NHRA's fault right ? No culpability for yourself ?

James since you offered me assistance with the scales and slip , I will offer in kind, we will have remedial reading lessons by Mandie at the Trailer at Norwalk, and an Advanced class on how to read a rulebook held later in the day, there is no charge......

Just doing what I can to offer the same type of help you offer :D

Re: What air cleaner base is NHRA Legal?
 

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 ?

Re: What air cleaner base is NHRA Legal?
 

[QUOTE=Mike Brogniez;190572]Lost 4hp with the hood down........Mine was engine dyno, my friend that lost the 4hp was on a wheel driven...

Re: What air cleaner base is NHRA Legal?
 

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

Re: What air cleaner base is NHRA Legal?
 

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

Re: What air cleaner base is NHRA Legal?
 

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....

Re: What air cleaner base is NHRA Legal?
 

Many run air cleaner elements in bracket mode and remove it for heads up runs.

Re: What air cleaner base is NHRA Legal?
 

That actually makes sense as well.......No reason to drink dust if you dont have to......

Re: What air cleaner base is NHRA Legal?
 

Bobby,

I vaguely remember one of the car magazines ran a test on a vehicle with and without an air cleaner - don't remember anything other than the results which showed the combination WITH made more HP. Plus the fact that some tracks are dustier than others (like the 2.8 mile trip at Route 66 :eek:) make me think that having an air cleaner makes sense. Obviously there's more to it than just bolting one on, and an open element has got to be better than the stock single snorkel, just part of the tune-up! It just has to look like OEM, whatever that is today!!

hey dont feel bad,at the maple grove divisional during tech inspection i had two nhra tech guys under the hood (fingers pointing,arms motioning,gestures going) finaly i said ok whats the problem??? they said you cant run a accumulator in stock !!!!!! note two tech guys,my first thought was they changed the rule yesterday ,so i eased into the issue by responding , yeh its legal unless you guys changed it yesterday?? its in the rule book!!!!,,tech guys response ,,show me ??? ,, response,,i dont have the book on me ,,,he whips one out from his pocket and hands it to me ,,, i thumb to the page and we read it in harmony ,, his response was i didnt know it was allowed in stock ,,but he did swing by the trailer later and apologized and said he was not thinking clearly ,he knew it was legal after the situation accured just had alot going on ,,, but you need to read the book ,be ready to go up againts these guy ,,they are human and the racers know there class ,whats legal and whats not gmonde

Re: What air cleaner base is NHRA Legal?
 

Good advice, NHRA Techs are Human and falliable, and well, there is a LOT across a LOT of different classes that I am sure anyone of us would get jumbled in our head from time to time. Most only run 1 or 2 classes, the Techs have to know ALL Classes....

When I was a plumber/pipefitter we went to a "State Unified" code, moving away from all the municipal codes and everything changed I only learned the new, but many established and intelligent inspectors would say "No, no saddle valves not allowed" while pointint to them on some add on humidifiers of a commercial install. My answer would go something like "Yeah, I think Akron had that code, I heard that, this state unified code is so confusing, even to me, see look, now THEY decided its ok to use on non-potable water, can you believe that ? But see....look....(while pulling and thumbing to the section) and look isnt that stupid ? but it says you can do it, and the guys we had here were from local xxx on travel cards..." But It didnt make the inspector feel like a dumbass, and it didnt put him down, meantime he learned something in a non-confrontational way.

People wanted to know why I was the youngest Journeyman pipefitter in 219....It was because I never had 1 single item fail on numerous large commercial builds.....but more importantly that was because I never pissed and inspector off :D

Re: What air cleaner base is NHRA Legal?
 

Attended my first race this past weekend at Maple Grove in several years. The stuff I saw on Stock Eliminator cars blew me away. Not the technology, but the blatant disregard for the rules. Stockers are so bogus today it is ridiculous.
After all these years Super Stock still seems normal to me.

Re: What air cleaner base is NHRA Legal?
 

Back in the late 70's we had a tech guy paying close attention to the top of our Hemi car's motor. During tech in. we though he was checking the aircleaner bottom.
Later in teardown he asked us to take the aircleaner base off, touched the intake manifold with what looked like a pen, then told us we were disqualified. I said a couple of "what do you mean M F,s"
And he proceeded to tell me we had an aluminum manifold and it was a 1970 car so we were disqualifed
I almost could not believe what I was hearing. Went over to Greg X explained and asked him how he was going to do with one less tech people.
That guy never came near our car again.

Re: What air cleaner base is NHRA Legal?
 

LOL....some tech inspectors are there just to be there and BS their way into the job like they know all. I have run across several over the years who just dont know much of anything about stockers and S/S cars. Im the first to admit I dont know all that much about the new stuff with throttle bodie, FI, computers, etc. Any dummy who is at least half of a car guy should know that the street hemi (and others) came with an alum. intake (65 race hemis had magnesuem intakes). These are the first guys who will sneak off and watch the races or BS with their buddies instead of doing the job. Greg X was one who knew it all by heart. Im glad I was able to work with him and the late Marty Barett from Div. 3.

Re: What air cleaner base is NHRA Legal?
 

My best ever was the "you'll pass tech as soon as you install factory floor mats"
(Read the rule book and determine how this braniac came up with this. And yes, he was serious!)

Re: What air cleaner base is NHRA Legal?
 

I had bought one from gm performance parts for my street car. Later gave it to Dad, NHRA made him remove it because it looked to swoopy!!!!!

Re: What air cleaner base is NHRA Legal?
 

I think what NHRA is looking for are the aluminum circle track air cleaner bottoms that a lot of racers are running. These are not close to oem but racers have been running them for years.

Re: What air cleaner base is NHRA Legal?
 

The above mentioned lessons were a typo. I will in fact hold them, but there will be a charge. (hey, I gotta pay the bills somehow!) The fee however, will be a menial one considering the irreplaceable knowledge gained. Your welcome.

Re: What air cleaner base is NHRA Legal?
 

I spoke to a super stock buddy Monday and his SS had one of these roundy-round bases. He was told to loose it. He doesn't know why, but it picked up .08 the next round! He lost on an explainable breakout. Guess he owes NHRA a big thank you!

Re: What air cleaner base is NHRA Legal?
 

i got ! to james never had a prob but they did make me take my hand brake out of my dragster they couldnt tell me why but it was in the rule book what a dumbass rule i just hope i dont lose the pedal brake atleast i had a backup!

Re: What air cleaner base is NHRA Legal?
 

James did you sell your baseplate to Dustin?

Re: What air cleaner base is NHRA Legal?
 

I was asked to remove my air base at the SuperNationals/E-Town and replace it with a stock type air cleaner base. The one I had did look like the one in the pictures at the SuperNationals. Selective enforcement or just that it was raining during tech? What will NHRA do if someone wins with one on? By the way thank you NHRA because my car picked up when I removed the roundy round air base, go figure.

Re: What air cleaner base is NHRA Legal?
 

No he had his own..
I really dont think the air cleaner base helped him.He was way faster than Tex.
By the way Larry I have seen alot or Chryslers with this huge plastic air cleaner base size of a stealth bomber.Can I use a 69 z28 fresh air cleaner assembly?

Re: What air cleaner base is NHRA Legal?
 

James Perrone, There is a picture of a air cleaner base on; Live from English town, post # 81. Aluminum air cleaner base. Legal or not? Tom

Re: What air cleaner base is NHRA Legal?
 

James, are you speaking of the cross ram intake for the Z-28? I bet it will look cool.
