Aluminum pan around webers

Dean Lampe · 04-24-07, 10:20 PM

Where can I find this type of pan? Or does someone have a source who could make it?

Hi,

I've been searching for the same thing, the only one I've found so far is from ERA.

COLD AIR BOX w/BACKFIRE PLATE: For Inglese Induction Weber Manifold - $800

Not sure, but it may only fit this manifold setup, also thought that the price was a little high but then I haven't seen anything else to compare.

Sorry, not much help....and I know the question has been asked before on the forum but hasn't sparked much of a response.

Cheers,

Talk to Fran. I saw one in his shop but don't remember where he got it. I'm sure he can have one made.

Dean,
I made this one though it's now obsolete as my engine is being mated to the ZF and consequently being lowered by approximately 100mm. so the new one will be much deeper. This picture was taken when it had the Renault gearbox. The small diameter tube which runs just inside the pan is connected to the 5kg side of a 7.5kg halon firebottle. It's just a simple folding exercise with a lip on the upper edge and then welding up the mitre corners.

Deane,
I can supply these to original spec, if you PM me I will respond.

Make it yourself...it's pretty easy.

Don't know if these are made big enough, but maybe worth a look.

Hey Dean,
There have been a few discussions on this topic in the past. Here are a couple of links:

http://www.gt40s.com/forum/gt40-tech...t=cold+air+box

http://www.gt40s.com/forum/gt40-tech...ht=pan+drawing

There was a thread that had a nice drawing already done, but the hell if I can find it now. It was from before the forum was rebuilt, so may have gotten blasted.

If anyone knows of the where abouts of the drawing, please post. I'd like to use it too.

I got a sheet of 3mm aluminium for £5 and cut the holes to suit. You need a pillar drill, hole cutter and I used a jigsaw to trim the plate.

Each engine/chassis combination will require a custom pan to get the correct size of the sides of the pan to fit correctly when the rear clip is in position.

Also each different made of inlet manifold will have different dimensions so I felt it was best to do it myself.

After marking and drilling two opposing holes for the weber studs the other stud holes were drilled after scribing them with a pin (has to be a pin as space is limited). The inlet holes were marked and rough drilled (about 4mm undersize, those hole cutters can drift some). Finished with a file.

I would imagine that any of Roy Snook's work is the real deal.
Any chance of a photo Roy ?

David,

Not going off topic about the pan issue, but when I looked at your engine picture, I noticed your headers....... I really like how the smooth and long gradual bends, and are chrome. Are these custom made by you, or ?

I would like to see a few more shots of your engine bay as well.

David Morton · 04-25-07, 07:14 PM

Hi Gary,
They were made by Tony Law in Leeds, England and were custom made on the car with slightly larger tube than that used on the GTD production
run and Tony actually made them himself with the promise that they would be significantly different from the ones he made for GTD.
Before they were used on the engine, they were chromed locally, along with the silencers and the heat guard on top of the silencer was home made in stainless steel. I was quite pleased with the result though I've been told the next headers will again be a significant improvement which will be in polished Stainless.

Dean:

Talk to Fran. He told me that he is working on a cold box, back fire plate and, in case you are wondering, an expansion tank with specs similar to the original. I will also be using Webers.

Gary Kadrmas · 04-26-07, 12:55 AM

David,
Wow.

Thanks for the information and picture of your car.

On a scale of 1 to 10..........Its a 10!

John Fitzpatrick · 04-26-07, 09:19 AM

Guys, was the original purpose of the pan to provide carb shielding from the radient heat from the headers or a plenum to exclude hot air from the engine compartment?
O/T David, how did the chrome hold up on your headers?
John

Bill D · 04-26-07, 11:01 AM

John
The intent was two-fold. First, to shield against engine heat, and second, to get cold air from the inlets.

It should also be noted that the originals used phenolic spacers on the Webers to further insulate from engine heat.

Doc Watson · 04-26-07, 11:10 AM

Like these..........

Note that the base plate isnt shown.

David Morton · 04-27-07, 01:43 AM

John,
The chrome holds up OK and though I don't really do anything to look after it I should by keeping it polished occasionally with Duraglit.
I like the various colours that the headers morph into as the engine warms up - sort of reminiscent of my motorcycles in the 60's which were all Chrome over mild steel. But the next headers and
silencer(s) will be stainless steel.
