And what sort of gains could you expect, not just figure wise, but in real world driving?
4 pot, simply 'cause most superbikes are 4 pots, so the carbs come in sets of 4!

That Golf set-up looks like it would draw alot of hor air in from under the bonnet...has anyone ever made a similar set up but with a plenum chamber etc?

I believe chap on retro-rides used a plenum set up on his bike throttle body and supercharged imp.

I'm very interested in Bike carb/Bike TB conversions

The car in question is mine (the one running GSX1100 Mikuni's on an M10) and I am busy fitting the 292 cam and Racetep four-into-one header. That should complete the breathing.

It was in TBMW last month. Header from the US costs £160.00 including shipping,tax etc.. D'Bilas 292 cam cost £190.00 but they sent me a clockwise (mines anti) so I have just bought a matching Dizzy drive to complete the project.

Then off to the dyno!
