How did you make those lexan side scoops. Beautiful work! Also, what are you pointing out with the red circle in the picture with the scoops together?

The imperfections I got since the plug isnt good enough yet.

Made in a vacum machine that heats the plastic, and pulls it over the plug.

Keep me posted. I just hope that you decide to sell some and that I can afford a set when they are ready. I've been thinking about this for a long, long time. I just couldn't figure out how to do them?


...fantastic idea!

Actually, I was thinking of making a few sets if some wants them, since making the plugs take too much time to just make one set for myself. Will definetly be cheaper than the ones you get from the known vendors.....

Very nice work!
I have been wondering if one could do something similar with the dog hatch into the engine compartment. It would be pretty extreme to be able to see all the whirly bits going round. Guess there could be some issues of how dirty it would get from the motor, or of safety if a belt broke - not sure how strong lexan is (maybe some thicker stuff could be used), or if a fire started in the engine bay I guess the lexan would melt through pretty fast. But I am willing to chance it and it sure would be cool!!
Cheers, Tim.

Tim,

I have an old Hall Pantera catalog labeled “Catalog 2000” that offered a Clear Lexan dog house cover with the purchase their Gilmer Belt Drive. It was listed on page 73 of the catalog without a picture. I don’t know if they ever sold the dog house cover by itself, or if they still sell it, but it may be worth a phone call if you’re truly interested in it.

Hi Garvino,
thanks for the info. I had no idea. Very interesting indeed . I was half expecting to get flamed by the community for being totally nuts, but now I can see I don't have to worry .
Cheers, Tim.

As far as I know, no vendor has ever offered anything like these. At least I have never seen them mentioned.

I was actually thinking more along the lines of the Lexan scoops like those that were used on the Cobra Daytonna Coupes but I like these better.

If you ever figure this out entirely and get them where they aren't flimsy and fragile, want to sell a few sets let me know.

These are reminiscent of the Ferrari F40 street car and to me are kind of "the Cat's meow".

You can always PM me here.


I'm wondering if you are going to need a third piece for inside of the scoop to reinforce it after you cut the slot for the air intake?


As far as the Gilmer drive and the lexan doghouse cover from Hall. A lot of the stuff like this that is in the color catalog were items that Gary used, was developing or had built into some of the "Hall Super Panteras".

Simpler pieces then this, although still in those catalogs are no longer sold by Hall since Gary's passing.

I guess that they just use up what is left in stock and then that's it.

You can inquire with them since there are some broken sets still kicking around in the back here and there but Tara needs to go an look to see what is there. Sometimes she is staring it in the face but she still needs to figure out exactly what the thing is and what it is for.

Good luck.

Most likely. I guess a thin ring of aluminium hidden to have something to fasten the clamp holding the hose will be needed.

Now plug is ready, and in theory, the vacum-formed plastic should have the same finish as the plug. Lets cross some fingers and stuff...

Shitty pic taken with my mobil phone.

Recived my new rims for the Toyo R888's. When time permits, I will have them widened a bit in the rear to take the 335's.

Love those wheels. Can't wait to see them on.

Just mounted my carbon covers, and spun alu breathers. I love them, and they make the engine look somehow a bit more modern Need to do some TLC on the rest of the engine now to make it look good for the season.

Just had to have this frame

I like your new wheels. Who's the manufacturer and the model #.
Thanks,
Mark

Will need to look at the box they came in. Dont remember.

Took the small hammer out today, and started to work on the pieces I need to make a new filterbox to take air from the scoops i work on.

Testing out the pieces for size. The top and bottom and the inlet will be in alu, but the housing itself is supposed to be carbon fiber.

..

The inside of the scoop is only temporarily put in place, but shows how it will rout the air to the airbox with a 4" airhose.

Nice workmanship.

There is one small problem with your scoop though.

The factory scoops that stick up like bat ears do that for a reason. Although they look a little strange, the top of the scoop is all that sticks into the air stream because of the aerodynamics of the shape of the Pantera body.

If you isolate the air cleaner by ducting to your scoops you run the risk of running out of air for the carb at high speed.

The air flow over a certain speed becomes negative and sucks the air out UNLESS the bat ears are sticking up into the air stream. Your scoops don't.

They factory scoops look weird because that's what DT needed to do to make them work on the race cars. They are factory race parts and weren't done to make the car look prettier.

How far out does those big ears stick out? A Swedish owner i talked to made his own, that reach a good 1,5" out. His is not ducted, but he said that at most speeds they worked (as in reaching into the air), and the reason he had for saying so was that they moved enough air to keep the lid over the engine almost dustfree compared to how much dust that used to be collected. I doubt I will run 170mph for hours..

Not out, UP^

I was thinking about putting vents on my car, but did not know about the "must be up" issue. What does everyone think of roof scoops to feed our motors if the side scoops don't seem to be perfectly effective?

I remember some one with a Pantera and a roof scoop. I think it was a Silver State racer and it was a Pontiac Fiero racing scoop. Looked pretty neat to me.

The side scoops are a high speed issue for a race car. Most guys who use them don't connect the ducts to the air cleaner. The issue is when you isolate the carb air intake to just the scoops and then go racing.

I don't even know if it really is a problem, just that you don't get any ram air effect into the scoop unless the ears reach up into the air stream.

I remember Gary Halls race car had just one scoop connected the the carb and the other just venting the engine compartment.

So, what I miss is not mostly the with of the scoops, but how far UP the outher corner of the scoop (like PIM's power scoop http://www.pim.net/spage.html ) reaches?

Yes.

Well, i will have to try these first, since the vacum-machine at my school cant take any bigger pieces than these, and they have to be able to get of the mold.

Well, here they are after the plug was polished, and even though there is a inner and outher piece,and many compound curves, they don't obstruct the view more the I hoped for. So, if they happen to work too, I would be happy

I'm not sure about the housing to the air-filter. It reaches 2" over the rear lid, and in that way obstructing a bit of the view. Not that much, but still, there is not that much from the beginning, and loosing some might not be ideal..

For my purposes these scoops would be fantastic. You are not likely to find me cruising down the Mulsane straight at 200mph.

And I am not running a single Holley carb. I am running Weber 48 IDAs and they will eventually get switched over to the IRFI. It is not likely at all that the scoops in my cat would ever get plumbed directly to the induction.

I think the scoops look fantastic! These are much better then the Ferrari F40 plastic louvres. If you ever get to the point of thinking of selling them, keep me in mind ok?

Incidentally, if you are interested in doing a little research on the subject I can tell you that there is already an air cleaner made for what you want to do.

It was standard equipment on the W30 Oldsmobile 442s with the ram air. 68-69 model years I believe. I don't have any pictures handy but I probably have them around somewhere if you can't find any, let me know and I'll look for them for you.

Looks great. Now you need some clear acrylic tube for the hose.

These guys have a lot of great options: http://www.spectreperformance.com/#CATALOG

Many nice ones there. Like the 16" alu with one intake.

These ones have too: http://www.ramairbox.com/index.html

But first, I would like to try to make my own..

PanteraDoug, you mean one like this?

I would like this one:

Yes.

....like this maybe? Fits under the motor cover screen, and restricts no visibility to the rear like the other did.

Will of course finnish it a bit better than this

I like it. Good thinking.

What about clear lexan?

Was just thinking in that direction. Some carbon, and som lexan.. Might be the way to go.

On the subject of airflow VS size of ears, this video doesnt show any sign of that the air is NOT flowing fast, and in the right direction along the cars side. Makes me quite sure mine will be sufficiently big.

You guys are too much!

The information doesn't come from me. It comes from DT. I had a discussion about it with Gary Hall 20 some odd years ago.

...and it is about the air flow at "speed" meaning high speed. I guess over 150mph or so?

The air gets dead in that area and the discussion was about if there was a ram air effect to the scoops?

Now I already said that for my purposes that just about any scoop would be fine. In fact holding my hand out the window for me would probably work just as well as anything.

Scientifically speaking? I wasn't around to do the testing but if you look at the factory racing scoops they do seem to have a point of interest about three inches out from the car and the point is close to the top of the roof. That location does seem to have an attitude of intent?

Incidentally I'd hate to have been the guy running along side the car with the camera.




Ah Pantera guys...gotta' love 'em!
