Drouin Supercharged Zed makeover.

10:1 comp 1075 cc kit? or blower compression pistons?

I had a Eaton Supercharger I was going to put on a 10:1 comp 1200cc kit but I did the math and found out it took 60HP to spin that blower. I also figured it needed a 50mm carb to feed it, so ended up selling all those parts to a import car guy, actually gained value over the few years I had the stuff!

The guy I bought the blower from had it on a RX7 1.3L rotary and it made 8-10 PSI of boost.

I figured it would run more efficient on a 1400cc kit with a big throttle body.

The other reason for selling is I would have had to fabricate a lot of custom parts to mount it on the engine. Was planning on running it off the crank end.

Yes! 1075 Wisecos at 8 to 1 comp.
These Drouins came with a 55m Hilborn style injector which i never had so the nearest carb i could find was the Super G.
I did run the smaller super B at first that i already had from a turbo kit but you could feel that it didn't flow enough and stifled the top end.

A few years after selling the supercharger gear I came across some snowmobile guys that offer huge flat slide carbs that take Mikuni jets.

They start at 48 and go up to 60mm!
