What about ITBs with a plenum? This is something I plan on trying with my aw11 blacktop project.

Here is a basic formula for runner length. 97000 / peak rpm (goal HP @? rpm). IE: 300hp @ 5900 rpm--- 97000/5900= a runner length of 16.4 inches.
Tezzpip on the UK Mk3 forums just had ITB's fitted to his N/A....thing sounds like a Spitfire 
IIRC they're Triumph 955 ITB's...

this formula wouldnt apply to a forced induction model though, right?
i just read this article entitled 'Simulation Helps Adapt Intake
Manifold for Multiple Models, Saving Millions.' got me thinking and thought id share. (pdf)

i have a an idea that may be rubbish but id like to build runners with some sort of grooved rifling like whats on the inside of a gun barrell and see if it makes any difference.But then again also, maybe i drink too much.
