Rotax Racing Superchargers (spacer)
I have seen on the PPG site that they offer a C-kit which is a large impeller and a 2mm spacer for between the SC housings.
Does anyone know what boost this SC produces at 8100 + 8500rpm.
Also on the same site they have the watercooled SC, what boost does this produce at the same rpm's? Is is the same size as a stock SC?

At 8100 9+ PSI
at 8500 11+ maybe 12
The water cooled SC housing doesn't produce more boost. It's just a housing that is water jacketed to cool the air. In fact, Bo Duprist tested this housing and it actually reduced boost. Hot air expands = more boost. When the air was cooled with the water jacketed housing boost was reduced.

I'm getting 12-12.3 on typical summer days in Toronto. I have never run it really cold yet....like below 55 degrees.

If you run it in cooler weather you will be surprised at how much more boost you get

thats,, all about air density,,, cooler is denser,,, even though it is less pressure due to it being cooler just like the intercooler ,,, it should have made more power so is boost loss through an intercooler due to less pressure or the air just getting denser and taking up less space ...food 4 thought
