I say it picks up close to .05

 

I always ran the K & N style. About those dimensions, with the extreme flow through top. Got a good deal on the screen type, and swapped it to find out when I changed to a more low profile hood scoop. In my case it didn't pick up any. Really depends on the amount of restriction in the original system, right? All we can do, is do an A-B test and see. So, post the results. Sort of interested in finding out if it did pick up.
In case it's faster, the screen type I got second hand can be bought for only $85 new. At least it keeps the rocks out, right?

 

I have one on a 1050 carb and have tried it with and with out made zero difference.

 

If your air cleaner is non restrictive and is not too close to your vent tubes it will be the same or maybe lose just a little.

 

I ran the K&N velocity stacks (actual filters were 7” diameter x 4-1/2” tall) on my truck for several years. It was a 585 BBC with dual 750’s that ran 5.80’s at 116 and 9.20 at 145 at 3400 lbs. I switched to a single 1300 dominator and fabricated an adapter to fit the same dual filters that I already Had so that it would fit the hole in my hood. It ran the same as with the dual 750’s. To answer your question; I took the filters off both setups many times over the years to compare the difference, but there was no change at all......none. If you have a stock paper filter you will probably see a difference. Maybe little to nothing with a high flow or K&N.

 

A well designed air filter and housing help control how the air enters the carburetor. In some cases this can be very important. There is a "possibility" you might slow down by removing the air filter/housing.

Engine Masters did a shootout on air cleaners. There is some differences, some small other pretty surprising.

 

Salad bowl!!!!

 

^^^Someone had to say it

 

It made no difference on our car.
