Costello Weber carb setup

Looking at some photos of an original carb set up on a Costello, it used a single DCOE mounted toward the rear of the engine and feeding the air / fuel mix forward. Was this viewed as a good set up or a bit too out there?

It worked just fine. And the original twin SU's facing forward worked fine as well

Thanks Perry,

OK, just a thought. What about a modified setup that used twin webers instead of twin SU's for my modified 4.6. Maybe this set up could be on a single or dual plane 4 barrel manifold. Potentially this could fit under a stock MGB hood / bonnet.

Anyone done this, or know someone who has done this........Thoughts / opinions anyone.

Cheers, Graeme

You can spend £1000's on re inventing the inlet setup mate.

The single Weber was ok. The twin SU's were ok. There are manifolds available for multiple throttle bodies as well.

I guess you are not after originality? So the next option is a low profile manifold and a Weber 500 I guess.

Let us know what your goal is for the engine? If you want to go radical then maybe think about fitting a a 4 barrel throttle body with high pressure fuel delivery to EFI fuel injectors in the body??

ie. EZI EFI type systems.

Thank Perry, you make a very good point. To optimise the induction system without going full EFI a throttle body efi system might very well be the way to go.

Perry,
I stumbled across Alfa 33 1.7 DellOrto throttle bodies while rummaging around the Fleabay Motors site a while back. 4 of those on a nice manifold should get things breathing nicely....
