I tried to find the thread, but it has slipped my search...

RotorSports helped me out w/ some parts on my engine. I built it myself, but needed new rear rotor and housing. Thats the only experience I've had w/ them and I was pleased.

I'm always suspicious of businesses who post only good customer comments (what abou the bad ones??) on their web pages.

Bryan did my rebuild, and I am satisfied with his work. He proved very cooperative while we worked out exactly what to do, and I believe he's more interested in long-term relationships than a quick buck.

There is nothing fancy about the water jacket mod.  The coolant passages closest to the spark plugs (hottest part of the rotor housing) are grooved so it disturbs flow and produces turbulence.  This turbulance actually helps with cooling efficiency.

You know, you can get all the benifits of the water jacket mod (and then some) by using Evans coolant.
And you don't have to disassemble/weaken your housings...

The other things I forgot to mention is the increase in surface area in the water passages for better heat transfer - duh.
I recommend this mod for all big power rotary engines, including ones that spin over 9kRPM.  You need to be very patient and consistent to get those grooves look really good!
