Most of the aftermarkets seem to be 48-52mm SBD etc)
I put gsxr750s on mine which are 42mm.
Theoretically 42mm bodies will flow enough for 200bhp fairly easily.

bike throttle boddies.
i just saw a set but only 38mm, so might not be bigger enough then.
thanks

I have 38mm GSXR 600 TB's on my Zetec, 174 bhp at the flywheel on the rolling road and a little bit of duty cycle still left. I would have
thought I could get close to 200 before having to upsize.

The guy that built my friends Pug 205 rally engines turned up some venturis to fit inside 45mm Jenvey bodies to take them down to 42mm. He reckoned
the increased gas speed in the area the fuel was injected would give a better spread of power and it's making ~275bhp on these!

Would make sense as it would increase the speed of the mixture at lower throttle openings, giving better mixing and cylinder filling. Shouldnt make
much difference at the top of the rev range, but should increase the power band.
