Carbon fibre elan airbox

I have been asked to create a mould for the elan weber airbox by several elan owners.

Just gauging how much interest there would be to make them available.

Cost would be around the £200 plus postage and packing.

Elan weber air box. Will post pictures when finished.

Which airbox were you thinking of?

Ditto on the design question. Also I personally would not need it to be carbon fiber, cheaper material would be fine. Finally, I’m in the recently be-nighted USA and would have to ask if you would go through the effort to ship it here. But in short, yes I am interested.

I had a nice air box and will need another. I am interested.

Hi, no problem to ship. Once i have an idea of postage cost i will let you know

Just following up on my earlier question, there are 3 different airboxes I can think of, S1-S3, S4-Sprint, competition airbox that doesn’t shroud the rear carburettor trumpet. Which one are you planning on making?

Thanks,

There are 3 standard types for the Elan . I refer to them as follows with my observation on usage
1 bolt- S1 and S2 and early S3 ?, this was a more oval shape than the later 2 and 3 bolt types
2 bolt later S3 and S4
3 bolt Sprint.
Plus you have the deeper competition air box that some sell.
I don’t know if airbox covers differed on Stromberg cars but the back plates would have been different and the bolt locations probably also due to the carb inlet locations
Also the Plus 2 airbox had a different angle on the inlet and only used the 2 bolt or 3 bolt types

Given the age of the cars all these can be found on any car these days. As with all things Lotus simple really :slight_smile:

I’ve also seen the 1 bolt design two ways, where the bolt comes in either from the fender/wing side or in from the engine side’; the bobbin being in either the back plate or the air box outer piece.

Interesting i have never seen one where the bolt comes from the engine side just another Lotus variation !

Hi, both of my S1’s have the single bobbin in the OEM airbox covers. Both early Bourne shells from mid 63 and early 64. Maybe the change occurred when Lotus took it in house, cheaper to drop the bobbin and add welded nut to the beck plate.
