Do you know the exact type of your weber carb? Are there any type number on it?

Unfortunately there is not so much information about weber carbs in Murena 2.2 on the forum...

Has anyone tried a similar doorseal as a replacement of the original?

Is it the right size?

According to the parts catalog there should be a plate under the engine. Unfortunately it is missing on my car.

Could anyone send me a photo how it looks?
Thanks.

I noticed one on eBay yesterday with a nice picture:

www.ebay.de/itm/Matra-Murena-Luftleitplatte-/320998638698

The plate has puzzled many Murena owners. In the auction, they call it a "Luftleitplatte" indicating that it somehow directs air into the engine room, but that was not the reason it was fitted. It was fitted on request of the German TÜV approval body to protect the fuel tank and it was only fitted to Murenas sold in Germany. It may also have been fitted to all 480 Murena S. Unless your car was originally German and you're insisting on getting it back to it's original state in every way, I think you should forget about it

Cheers,
Anders

Thank you for the info. Now I know why it is "missing"...

[klumzer]

Could anyone send me some photos of the upholstery at the rear compartment? Mainly at the rear side windows from the inner side and above the mid window.
I forgot to take some before removal - stupid me - but now it would be good to have some to send to the upholsterer.

Thanks in advance.

Anders, are you sure that the plate should cover the fuel tank ? I have an old illustration from a sales brochure in my mind. Of course that is now 30 years ago,  but i´m pretty sure that there was written it should create a little vacuum by high speed to get the hot air faster out off the engine-room. And in cause only the german Autobahn was without speed-limit they made it only for the german cars.

Interesting. I find it a little hard to beleive though, as the plate is mounted under the car in front of the engine, so it shouldn't affect suction of air out of the engine room.

Suction of air from the engine room is driven by the rear end of the car: The two air channels under the trunk exiting in the rear bumper. This is actually a very clever design since there's a considerable vacuum in that area (depending on speed of course), and even more so on the Murena S with it's large rear spoiler. It's a nice engine (and especially exhaust) cooling design and obviously one that was inspired by Matras race cars.

Theoretically, the plate could create a bit of flat bottom ground effect aero increasing downforce slightly. If that was the case, the location near the middle of the car would make some sense. I'm still skeptical, since with the relatively small size of the plate and the large ride height of the car, I doubt if any flat botton effect would be measurable.

The rear spoiler as fitted on the Murena S is very effective though. It's size means a considerable increase in downforce on the rear, probably significatly increasing rear end stability around the top speed of 200 km/h.

Are you having your whole car retrimmed?

I'd be interested to know how much your trimmer is asking, as I will need new carpets for mine in the back. Are standard black ones still available?

I always thought it was just a drip pan to catch leaking oil.

Yes, I will have the whole car retrimmed. In the cockpit all the fabrics were worn, the roof panel and the seat cushions too. The original light brown fabric was not too tough... In the back it looked bad because of the sun.

Retrim of the rear compartment costs about €4-500, but it is relative. I think in the UK it is more expensive.
A good upholsterer can provide any fabrics what you need. Maybe the black one is cheaper than brown.

If you want to have the rear compartment retrimmed you have to do some extra work. First you have to remove the side windows. The leather goes under the glass covering the B- and C-pillars. That is why I need some pics taken from the inner side.

Thanks.

Are you having leather or cloth then?
