|

Guys,
My Brakett air filter bottom pie pan has several holes in it. Please see the picture. They don't make sense to me because I think that they let unfiltered air into the carb. Are those holes supposed to be there? Why?
A related subject. Is challenger filter installed with pie pans? Does it come with it's own pans or is one supposed to reuse the original ones? Does anybody have experience with challenger on 78 tiger? It looks like it may not be a good fit:

Thank you,
Boris.

I don't see where does this 1 inch line connects to now. Where have you been connecting it to?

Hi Boris,
You can get a new cover from Fletcher. It isn't supposed to have those holes. I've seen a lot of weird things. This is just another example of someone who doesn't know what they're doing.
As for the Challenger air filter, I tried it on mine. I noticed the CHT/EGT spread was worse with the Challenger. Your mileage may vary.

Hi
I have been using a Challenger filter on my Tiger (75), for last 4 years and it does make a difference, as Gary says, mileage does vary, but on a run-out 0 360 it raised the full throttle ceiling from 8000 per the manual to closer to 9000 ft on the same day so it does breath better. As a long time user of the same filters in my car, Flow master, they do actually give more air volume, and also as Gary says probably make the unbalance of our intake even worse! On a new 0 360 I can say that the Challenger may even help more, even at 14,000 it still has throttle left. Of course when I can afford Gary`s wonder I will be in heaven!

Bill,
If you have a 4 cylinder EGT/CHT, particularly a fast responding JPI, if you could, get a stock air filter and do some independent testing on the filters.

Hi Gary
I do have a JIP 4 cylinder and did run some tests on it when we put the new engine in, but don`t have the data anymore, best I could remember was the CHT went up on all cylinders, but EGT went down, I assumed due to different flow patterns. But a note here also installed a fine mixture adjustment then and that may have contributed to the different patterns also. You have a good idea and I will see if I still have the original filter in Hanger and if so will do some tests. Best I could saw was with original motor, 2200 hrs, it ran a lot stronger with the Bracket, but no JIP then so hard to say.
Will have to do some new tests just for fun though, do you have a stock filter lying around in case I discarded my old one. Great reason for visiting Auburn again.
Thanks
Bill

Thanks for all the answers, but a couple of questions are remaining:
1. does the Chalenger filter use an aluminum plates, which David Fletcher calls "pie pans"?
2. if it does, does it come with new ones or is one supposed to reuse the old ones from Brakett filter?
3. David Fletcher on his web site suggests that they don't fit well in
77 to 79 Tiger airbox. Does anybody have a Chalenger filter on a 77 to 79 Tiger? What is your experience? A little tight squeeze or a horrible struggle every time?

I use a Challenger filter in my Converted Cheetah. It is a 76 model, but do
not know what year the airbox is .No pie plate, just slides in the airbox.
Just recharge it every annual with a kit you can buy at Wall mart. Actually,
you can buy the whole filter at Wall Mart, K&N filter for a Slant Six
Chrysler product, around 1976. I think a Dodge Dart will work.. About 24
bucks, but no STC.!

Oh, sorry. The Challenger (which is a K&N E1000 from a slant 6 Dodge) fits fairly well. Without something to keep it round, it distorts when installed. K&N supplies a grease to seal the surfaces to the air box.

Hi Bill,
I have the filter from my plane that you can use. Come on down. I'd like to know if you see what I saw on the temps. It would be better if the K&N had something to keep it round.

So exactly what is supposed to hold a 1977 Tiger bracket air filter
centered in the airbox(and not fall to the bottom)?
Does anyone know?
I have seen sticky (on both sides) rubber tape used on the front and
back face of the filter pie pans. This seems pretty lame and it seems
it would offer the opportunity for worn rubber to get into the
carburetor.
Is this really the origial design?

John,
By design, there should be a block on the bottom of the airbox which holds the air filter up. There should be a tab at the outer most corner up inside the airbox. There is a deflector plate at the inlet which holds it to the center.
On N28840, I replaced the tab with a stainless steel tube, held in place with a 1/4 inch bolt.
The design of the airbox allows the filter to move around a lot. It's a shitty design from the point of wear and tear. Just the vibration alone wears holes in the pie tins around the parameter. Over the years I've tried a number of things to keep the filter in my Tiger from eating itself. Right now I have two blocks in the bottom in an attempt to keep the filter from moving too much. It helps, but not a lot.
What about a redesigned airbox with an opening on top to drop the filter in?

Gary:
Years ago I tried a block at the bottom but the filter machined itself into it.
The world could use an improved design.
(I note there is a hole at the back of the airbox that could be used to secure the filter (with a bolt if a nut were welded on to the air filter pie pan).

So exactly what is supposed to hold a 1977 Tiger bracket air filter
centered in the airbox(and not fall to the bottom)?
Does anyone know?
I have seen sticky (on both sides) rubber tape used on the front and
back face of the filter pie pans. This seems pretty lame and it seems
it would offer the opportunity for worn rubber to get into the
carburetor.
Is this really the origial design?

Yes, that is a problem. On one installation I tried two blocks stacked and shaved. I mounted them so they hit the filter and not the housing. It would put a big dent in the filter, but seemed to work ok.

Years ago I tried a block at the bottom but the filter machined itself into it.
The world could use an improved design.
(I note there is a hole at the back of the airbox that could be used to secure the filter (with a bolt if a nut were welded on to the air filter pie pan).

John,
By design, there should be a block on the bottom of the airbox which holds the air filter up. There should be a tab at the outer most corner up inside the airbox. There is a deflector plate at the inlet which holds it to the center.
On N28840, I replaced the tab with a stainless steel tube, held in place with a 1/4 inch bolt.
The design of the airbox allows the filter to move around a lot. It's a shitty design from the point of wear and tear. Just the vibration alone wears holes in the pie tins around the parameter. Over the years I've tried a number of things to keep the filter in my Tiger from eating itself. Right now I have two blocks in the bottom in an attempt to keep the filter from moving too much. It helps, but not a lot.
What about a redesigned airbox with an opening on top to drop the filter in?
