Air Cleaner

A smaller diameter filter assembly is definitely a benefit.

Your engine cover is gorgeous. You know I think you have a wonderful eye for design.

I would think an air cleaner lid that reads "De Tomaso", "351 Cleveland", or "Pantera" would be more widely accepted. I personally wouldn't want one with the K&N logo on it.

Another current fad is to have a threaded nut welded to the bottom of the air cleaner lid, instead of a stud poking up through a hole.

Kirk,
The 2"raised engine cover maybe also work on open Webers?
Or is the intake air too hot ?

Thanks for the input George. I did not enplane the project well.

Started with a K & N off the shelf filter with the filtered top. Then removed the filter area, free handed the new 9" center, polished the edge, taped the edge, bead blasted the remaining center and shot it with DP-90. Then installed the GTS to match the car's Euro GTS pedigree. The center bolt was a SS flat allen head recessed into the lid so I could keep it white using the original GTS emblem material.

The trick was to lower the base because it is raised. Looking for something that would hold the outer filter surface flat and allow me to press the center lower took some looking. Got lucky by using a rear Pantera rotor which was the correct DIA and held the filter mating surface flat and then used an old Pantera axle with studs which held the axle in the center hole and then pressed it down. It worked remarkably well to lower the filter overall.

Removing the filter was a project though. It was glued in with what appeared to be urethane windshield adhesive---it was a bitch to get it out.

One could build the entire top using a thicker 11" blank and turning the filter area into the bottom and then machine in anything you want if your pockets are deeper. This was an effort to make a smaller filter not intrude into the deck and keep it as low as possible.

The 9" new center can be made in any look someone wanted just buy having an emblem made which is a bonus for individuality.

I have fought with filter ideas and shapes for years and the reason is a story by it's self. Air flow was explained to me in depth by someone with allot of racing history and why things work better or not. I sat in his office for several hours and talked about his history which I'll never forget---great guy.

This is an offset base I made many times to keep the filter forward.

Here it is installed.

With a very tall cover. This car had a Parker Funnel web intake which is quite tall.

The "Hall" filter top in the last 2 pictures, has it been turned-down to 11"?

Standard size George. That is why the base is off set. Also had to turn the lip so the filter would fit.

Sorry if this is stealing the thread, but here's my solution to getting a full size filter low and offset to clear the lid, all standard Summit parts. You need to drill a hole in the filter bottom to clear the secondary fuel level bolt/nut, and then cut a little in the filter element as well

I had run the drop base for many years with the open filter top, it worked great, but I have a high spider intake and had a problem with vision out of the back window, so I found this answer. It required cutting and fitting the 4" aluminum pipe.

The powder coating of the entire part brought it together, and the top of the carb piece is only slightly above the lower window edge. Spectre Performance, has a plethora of intake parts.

If it matters, I like everyone's solutions. Seemingly simple things like an air cleaner are not as simple as they seem on a Pantera.

Spectre won't let their picture be copied from their site, but here's the link.

Not to contradict myself but this base plate looks like it could solve both the offset and the height issue in just one part?

Doug, that's the base I have. It would clear side hung floats I think, but center hung floats require drilling a hole (that very conveniently ensures it's not put on in a wrong angle)

BTW, for my Longchamp I needed a lower base, I never found one that would just fit, I found one that fit with an hour of hammering and modifying the filter element slightly. Strange nobody produces a tea-cozy for a center hung Holley?
