Carb "air screen" for track-only use?
      #6559673 - Thu Mar 31 2011 09:18 AM

Anybody seen or used these? http://www.jegs.com/p/TICU-Racing/TICU-Racing-Full-Flow-Air-Screen/1566809/10002/-1

I'm wondering whether something like that would prove effective enough for track-only use (i.e. swap from regular air cleaner to this w/ a plate attached to seal the screen to the scoop) to provide some additional space between the carb and hood and free up my options for intakes to run w/ the Victor heads. Considering I've been using a 3" drop-base air cleaner, it's also not clear how much actual space above the carb this would add in comparison.

I really don't like the idea of running w/ no air filtration system at all on the track. However, I'm not sure how much this will do beside stopping birds, wayward children, rocks kicked up by cars ahead of me in the burnout box, etc. Maybe that's enough for just making passes down the 1320.



Oh, I also think they're HORRIBLY expensive for what they are.

I think mine will work just as well as those and they are a lots cheaper. I got 2 radio speaker grills(got Lucky and found some metal ones)to run on mine.They come in all sizes,just drill a hole in the middle and bolt them down. Check mine out & see what you think.

PS The man at the stereo shop down the road give me mine. Most stereo shops have some laying around or can order you most any size you need.
""CHEAP""

There is a reason for a air filter, it's to filter air. A buddy of mine bought one of those air screens, as you said , pretty expensive , they look trick, will screen out the rocks and smaller debree. The piece sets about 4" high , he cut about a 1" off the bottom of his to gain some hood clearance, was a waste of money as he went back to the K&N filter. If you have carb/hood issues now I wouldn't recommend it.

Mine only set about a 1/2" high. If you notice mine does not set on the carb.(injector on mine)flange. The scoop tray stills sets on the carb. flange so there is no added height.

I may be wrong but in my 20+ years of racing I have never used or saw the need for a filter on a Race-Car. Any kind of filter at all would hurt the air flow,hurt the hurt air flow kill the HP.
On a street/strip car Yes I see a need for one.

100%
i am the air filter nazi on account of what i see when i tear down engines that run without air filters. also, consider the carburetor. a precision metering device with exposed orifices, and you're going to leave it exposed to an unfiltered airstream? i see it at the track all the time. "my car ain't idling right. can you come touch the carburetor?" well, loogathere, IT AIN'T GOT NO AIR FILTER ON IT! airbleeds are all crudded up. airhorn looks like someone poured sand in it. lunacy.

I have been thinking about this myself,the opening in the SV1 carb is very large.When I saw one of these in the kitchen,it clicked!!I will end up with a pair of these for when I remove the big K&N's

I think it was Chevrolet that used a mesh " diffuser " above the carb and inside the air filter.
The logic was to straighten out the air flow or reduce turbulence or some such.
I have seen pictures and I believe they only did it on H.P. big blocks.
But their engineers thought the idea had merit obviously.
I don't think the gains of running without a filter are worth the shortfalls.
Now , a restrictive system is another story.
I see a lot of tunnel ram set ups with two tiny filters on them and have to scratch my head.
But with quality components , I don't think the power loss is enough to lose sleep over.
That being said , I don't run pro stock.
There are applications where they do hurt performance enough to matter.
But for a street / strip car , I'll always use one.

That is a picture of corvette with the L88. I also read that racers found a performance increase by removing the mesh filter.

I'm sure at some power level the air filter does become a restriction...but I've tested on a dyno up to about 600 hp with and without a 3" K&N style air filter with a drop base on multiple occasions and found no power loss with the filter.

Did you re-jet to see if you were at true max power...
ALL filters have a restriction its just a matter
of how much... I use to flow air cleaners(and the
housings) for Chrysler.... we would try different
filter elements in the same housing then we would
try different shapes of housings... it ALL makes
a difference... some are just small differences

Very true if you race all out, but for a bracket racer
its not critical... basically the air cleaner/housing
is no different than the head port itself... a little
shape change here or there makes a difference

My garage/trailer queen has a couple of those Mopar horns. Chrysler engineers used to recommend these, however I notice that no SS/AH cars run them. I have always wondered if they restrict flow. I do think that they lower the stress level when you leave your car unattended.

my screens seem just fine around where I live. Not much dust and gravel in PA....rains too much!

I've had the engine apart a few times and no wear that is any more than anything else. Carbs stay clean too.

One thing that helps is that I don't have a hood scoop. Flat hood. Car runs just fine at the track and gets about 1000miles a year put on. This engine is about 8 years old now.
