Evenin' I'm currently looking for a project for my final year at uni (next year) and had a bit of an idea involving the weber manifolds. Basically i was wondering if there was a manifold available (apart from the swan neck type, which aren't all that great ) that enables a weber 40/45 dcoe to be fitted without bulkhead mods, but that doesnt impare performance?? I was basically thinking i could develop a manifold that does this, as it could be a very popular item if it works!!!
So was wondering a) if theres anything about that already does this, or
b) would it even be possible

Thanks in advance

no i wouldnt be possible. DCOE's must be mounted at 90 degrees to the engine, and the difference in distance between the inlet ports (width) and the distance between the 2 chokes on the weber has to be accounted for. Also, it has to clear the middle exhaust manifold.

Not possible im afraid.

Balls! lol! Back to the drawing board then!

It is possible, I did it using a Maniflow 3.5" inlet

still a bit of a swan neck though isnt it, absolutely ******* torque. And you cant get a good filter with good ram pipes on, thus... your better off with an SU.

All manifolds will have a slight swan neck, I had over 140 bhp with the 3.5", shows its very good indeed. I now have 5". Torque is the same, but bhp is higher now
