How would you go about Supercharging an engine on Bike Throttle bodies? obviously you would need supercharger, intercooler, plenum etc, but would the throttle boddies need any special modification etc?

i shouldnt think they would,so long no boost can leak out.

Depends how much boost you're planning on going for. Lots of TBs will take a little boost but most will leak if you go for big PSI.

I've gone for a single RS Turbo TB (ie something designed to take boost)....

my pals got a tts charger on his zx14r running 6 psi only mods are block spacer that's it works fine

i've always wondered how difficult it would be to enclose all the TBs (maybe easier with carbs) in a ali airbox which is all underpressure with filtered air inside, so the pressure is the same inside and outside the carbs

The only air leak that I have noticed is on the idle bypass on my 954 blade TB's, beyond that its a straight tube with butterflies and injectors pointing in.

The idle bleeds air from around the mouth of the trumpets, I just use the butterflies to regulate idle now when warm, cut off the cold idle bit that was a stat thing.

i half made a plenum for my zx9r carbs,
i was having trubble trying to get it air tight around the trumpets.
if you can weld have a go at making a plenum with a single tb

You need to get in touch with ,, swalf3,, a member on here, he's got a Cateram R1 super charged, he would put you in the right ball park!! using a rotrex and a bit of fabrication done it for a reasonable budget!! must get in touch with him and go and see it for my self.
