Triple carbs

Need ( ok WANT ) carb setup for Atmo .

[stephendell]

Suggest you contact Rupert and arrange a p/ex deal!

Or ARR ( http://www.alpinerenaultrestoration.co.uk )
or ART ( http://www.alpinerenaulttuning.co.uk)
I think Treico ( http://www.treico.de )
Simon ( http://www.simon-auto.de )
and mecaparts ( http://www.mecaparts.com )
all do them as well.
I think MrD's alternative is the cheapest.

Are there many PRV carb setups about
Can't stretch to new so what/where/make to search

[stephendell]

ARR have sold all theirs so if new is not an option I would guess Rupert is the best bet (don't forget the commission Rupert )

Another option

Would this work with a custom adaptor plate to the manifold

Ive looked into different carb setups in the past. Problem with the atmo inlet manifold is there is two holes in it, one for the small 34TBIA carb and a twin hole for the double 35CEEI carb, so very difficult to fit a big Holley/Edelbrock and the like....

Also the new carb wouldnt be in the centre of the manifold either, the 35CEEI is at the front so there are different inlet tract lengths to each cylinder

Its also only been reported that 185bhp is available from the atmo engine with the triple carbs and free flowing manifolds and system. Upto 200 is possible with new distributor curve and high lift long duration cams, but you loose a lot of low end grunt.

I got 172bhp and an extra 24lb of torque at 3500 just by advancing the ignition and running an adjustable fuel regulator and Facet racing fuel pump, with standard manifolds and exhaust, the power curve is below and amazingly flat..

Do Renault do it on purpose They do come up with some superb ideas ,but also a lot that is technically known as wink .I think they do it for the sake of it .Example ,why use silly switched door release, anyone that doesn't know breaks them trying to use ,then put a far better and easier to use safety release overide on the floor

They did make it better on the A610. It has the door handle and mirror controls on the floor only, so the only wiring in the door is to the window motor and speaker.

I think injection would be a better set-up.
I'm sure others can tell us if this is so.

Yes, for half the price of triple carbs you could fit a nice Safrane/Laguna V6 engine, and have near 200bhp with a decent exhaust.

Just more work......

A guy in France is running a Safrane high compression lump with after market management, 290 degree cams, lightened balanced etc and is making 274bhp.

I don't want to swap the whole lump out .I prefer to get the most out an original engine otherwise you might as well buy a kitcar

Before typing this I have to point out that I don't have a clue what a machine shop/fabricator would charge, so this may well exceed your budget


If you can get someone to make up an inlet manifold then you could use bike carbs, which are very cheap (have a look on ebay...).

In fact you could get a few manifolds made up if they were reasonabley priced. I'd certainly be interested.

The problem is though bike carbs won't be downdraught..

Having a manifold made would be very expensive ,they are normally cast ,to machine from a solid billet would be a nightmare and you would have to do it in two halves and I haven't the knowledge to do it properly .Thats why I was looking at putting an adapter plate to suit a big carb .This I thought would work as you only have to get the inlets positioned ,but as DG points out the std carb set-up makes this tricky .
The small carb is there for idling and initial acceleration then the big boys take over could you lose the smaller carb and position a big carb with a sandwich plate that's machined on its underside to channel to the twin inlets .
