Nialls supercharged GTi6 - project tidy up

[Grant]

Doesn't matter as it's getting charged, turbo/super manifolds are always like that. It's NA engines where you need the manifold/bodies as long and smooth as possible.

Not necessarily. It purely depends on the pulse of the engine. Inlet manifolds do not want to be too smooth, otherwise you will suffer a lack of turbulence. This will consequentially reduce the atomisation of the fuel injected, and increase knock. Inlet manifolds are seldom polished, and left quite rough for this reason.
