Is it possible to install IDF's on a RHD  without  having to move the vacuum pump ?

Any experiences of your own in this area?

What do you mean by "vacuum pump", I had IDFs on my 131 on an original 124BC manifold with a BC aircleaner. No clearance issues anywhere, it sounded like heaven and went like a scalded cat.

The "Brake booster & Brake master cylinder" are on the RH side of my car, with intake on the left there are no clearance issues for fitting IDFs..

Here is the photo I got from Guy Croft (who has always been extremely helpful and informative and ready to share his experience with all us DOHC funs). Guy says his experience with mounting DCOE in a RHD 131 is limited.

The picture shows Guys own M 131 intake manifold (note the angle of the manifold).

I understand that the angle was designed to make sure the block-mounted distributor is not in the way. There are also straight manifolds, which I believe were used for some models of 124 (see picture).   

Maybe there is someone out there who drives on the right (correct) side of the road and has experience with installing DCOE Webers or similar like Delorto's  in a standard  version of 131?

In Polish we also use "servo". My garage English is limited (largely to American English). In US this is called "power brakes" or "power assisted breaks" and the servo is called ?vacuum booster?. Maybe it would be fun to create a useful quick reference of English (UK and US) automotive terms.

Remember when I first heard that the trunk is a "boot" and fender is a "wing", the hood is a "bonnet". It took me a while not to laugh whenever I heard these funny terms.  Grin So language is a matter of experience. I am sure our Aussie friends have a good laugh occasionally as well. So do not be surprised when someone calls the "servo" a "booster" both are proper English terms , though only one of them is British.  If you have not noticed English does not always mean British. This is the price of making this language the principal international language of communication. Cry

An incidentally they are on the same side (in a car drivable on the right =correct side of the road! 

PS: How come there are no capital letters in your post.   Tongue

We have guards, wings are on aeroplanes or birds! Fenders are something you hang over the side of a boat so it doesn't get damaged at a wharf. Grin

Miro, you might want to look at this:



This is my LHD (German) 131 (I assume this is what you meant by saying "...drives on the right side of the road"). This setup is from Ritmo 130TC, two Solex side draft carbs on a Ritmo inlet manifold. Clearance is tight as you see, we had to cut out a section of the fourth trumpet to clear the brake booster.

This setup has been working now for nearly 40,000 kms without problems.

Best regards,
Robert

I see what you mean its very tight,,, Roll Eyes  GC did an alloy plate instead of the rubber mounts for the 130tc
    which uses up the least room of any manifold  ,which is the way ,it looks like you must go unless you try a remote servo...

ROBERT , THANK YOU VERY MUCH !

 THIS IS MOST USEFUL.

Could you tel me how much space does the inlet manifold take ( in cm)  and what is the total distance between the head and the end of the carbs ( without the trumpets ) See picture I got from Guy Croft in my previous post below.

GC pictures show 24 cm. Is yours shorter ?

Also, is the130TC manifold  straight or angled ?

What is the size and model of your Solex?
