9" Air Filter Drop Base - How Much Interest?

Shows that great minds think alike, Michael!

I am currently using the flat base that came with a rather inexpensive aftermarket filter....I trimmed down the circular flange so that the underside of the base just barely clears some "bumps" on the side of the Edelbrock carb I am using, but it sure looks to me like the air coming in from the sides needs to make an immediate 90* turn to get into the carb. I'm hoping that the air coming in the X-Stream Filter top will provide some direct in pressure and help with that transition, but with only about 1/8" to 1/4" between the X-Stream Filter top and the underside of the hood scoop, I'm not really sure that there is much air coming in through the top filter.

One thing of which I am sure, though, is that with the 9" X 2 3/4" K&N filter and the X-Stream Filter top, I'm waaaay ahead of the 9" X 1" paper filter that came with the car. I'd still like to be albe to use that nicely raised and radiused base that came with the X-Stream Filter assembly, though.

One thing to watch for.....the #E-3530 filter that came with your X-Stream Filter Charger assembly has an ID of 8" and an OD of 9", but the #E-3510 filter that you'll be replacing it with has the same OD, but an ID of 7.5".....I'm not sure if there will be any interference with the X-Stream Filter top or not, when you get the replacement filters would you mind posting on this thread to let us know if the greater "thickness" of the K&N filter posed any problems (K&N makes 2" tall 9" OD filters in 7", 7.125", 7.5", and 8" ID's)? I'd appreciate it!

Glad this worked out for you!

Cheers from Dugly

Thanks Dugly!

My metal spinner friend is going to make a 9" FLAT plate with a 5-1/8" hole and 3/16" turned-up lip on the outside, out of material that is thick enough not to bend/warp. I will probably have to make two small relief notches for the float adjustments on my 4150, but not much. That's all I can do. Then, it's just a matter of which filter will fit, noting the comment above about trimming a small amount around the hood scoop opening, which I'm trying to avoid, but may have to do in the interest of airflow. I, too, would like to use the "venturi" type base, but that ain't happening and my Stellings 8"x1" certainly didn't have that. So, they way I see it, with the Extreme top, I'm probably tripling the airflow no matter what, which can't be bad!

BTW, watch the "For Sale" section on this site for a bunch of nice unused K&N filters once I solve this puzzle!!

Here are a few pics of what I want to do in a perfect world. Pics are with the K&N "Venturi" baseplate, which would be great. Hey, Bill Wallace, if you're still watching this thread, how did you trim your hood? Also, did you allow for the engine tourque-twist and movement? I really hate to cut my pretty hood up. Paint job on this ride wasn't cheap! The 9" just seems to hit each side by about 1/4" so it kills me!
So does anybody have any suggestions how to open this hood opening with the least possible disturbance to said paint, scoop etc??
I know....probably just go with something shorter, but the motor really wants air!!

Drop the engine 4".

You'll sure choke the cfm with a drop base. Only the top half the filter will be sucking air.

The other question is, the turkey pan was made so the filter would sit down in the pan, so the air directed to the carb from the hood scoop is sealed, thus giving the most cold air possible. To me, this renders the pan useless.

But, next to a dual quad, I really like the looks of the turkey pan, just awesome. I can't utilize one because it hits the front,... of my hood scoop. Other wise, I would have it. With this CRAP,...... life's a big turd !
