ive never tried it myself but thats why i took that picture of the zrx turbo when i was in monterrey ca.couldnt find the owner to get any details

Are you sure that is not an injected bike that only looks like it has carbs??

Not an expert or experienced, but Google found me this:

I also have the Turbo book referenced in the blow-through paragraph, but I haven't read it yet (the pictures are pretty, though).

The book does have a brief (3 pages) chapter on motorcycle turbos and shows an R C Engineering kit for the Z1 using a special Keihin carburetor (that's all it says). I'll scan the photo in and post it and see if it helps anyone out.

It also mentions a Cline Turbo Technology kit made by Blake Enterprises that could make a stock Z1 hit close to 190 with 18psi of boost. Damn. Of course, this kit uses "water/alcohol injection, pressure-retarded spark and a separate oil pump and filter."

"RC Engineering kit for Kawasaki Z-1/KZ1000 uses Rajay turbocharger and waste gate with a specially built Keihin carburetor. Company also has kits for Suzuki GS750/850/1000 and Honda 750 fours."

"Turbochargers" by Hugh MacInnes, Page 140.

that carb on the rc kit isnt being force fed though

Really? It's a draw-through? It's really hard to see from the picture but it looked like the carb was directly connected to the boost side of the turbo. Guess I was wrong.

It's a draw-through, but could be very cool if you can find one.

Blow-through Nomad.

and a another blow-through ZRX1100

Well I have found out that just about any carb can be used in a blow through set up, except the CV vacuum type carbs. The bowel vents need to be tied to boost, a boost referenced regulater, it adds fuel pressure as 1 lb of boost adds X number of pounds of fuel pressure, some are set some are adjustable and obviously a fuel pump.

It seems the reason the KZs are all draw through is the amount of room behind the carbs. Since I am moving my battery and electronis to a spot above the rear tire I may be able to pull this off.

keep us posted.
