A nice bespoke manifold will always flow in from the side, the less bends from turbo to manifold the better and of course the internal design of the manifold makes a huge difference too.

I persoanlly like center feed, the old turbo ford inlets were good design. Im just increasing the size of the plenum chamber on mine and using efi bottoms. cossie throttle body up top and thats hopefully enough for 400 bhp.
What power will the new spec engine be Gus ?
Which manifold are you referring to? Both the MFi and EFI are a centre fed manifold unless I am missing something
.
Mr c was the same
Always said that the stock inlet was good enough and could do the numbers
Til he changed
Always an interesting topic.
Here is one for you? If you were running around 220-240BHP would you bother about what manifold you have or just leave it? So far, my ZVH has an MFI manifold and is making 230BHP & 18PSi. IIRC it's running a Piper 285T cam and a Stage 3 head believe to be of PE origin.
