Sorry - we don't get much time to look at these forums --
Our turbo RX8 (easiest to see from our Facebook page - link on our website) that we built a few years ago has the GSLSE rotor housings -- so 6 intake ports, 6 exhaust ports, 5 exhaust pipes.
Rotors are RX8 cut for 2 mm RX7 ceramic apex seals. Mild street port, 11 pounds of boost, made 435rwhp at 7500 on the dyno at Road Race engineering last week.
Ran great last month at the Import Tuner Magazine Front Engine / Rear Drive shootout at the Streets of Willow, and this weekends MotoIQ Pacific Tuner Championship/NASA at California Speedway.

Don't know - they would not tell ANYBODY! -- just kept saying wait for the magazine.
The RX8 did not win, and was not last, and ran all day -- what we wanted to accompolish.
The car is still a "test mule" for us. It was built for Redline Time Attack, they imploded. Global Time Attack is still a question. Road Racing is what I prefer to do, so we set it up to be able to run at least 30 minutes at a time.
At things like any Time Attack format, ot that "Shootout", there are NO power limits and no weight limits (called expensive and fragile)-- so the RX8 is way underpowered (at 435), and way overweight (3000 pounds). The MotoIQ thing, and NASA ST2 are both 8 pounds per hp, so for last weekend in was de-tuned to 378 rwhp.
It was very nice to be able to race for 30 minutes straight.

Did you guys ever dyno above 7500rpms? I bet that engine would make power to 9k rpms, and probably another 50rwhp..
We've got the pport engine together and engine flange made. However upon doing a coolant seal " compression" test, we noticed one of the sleeves leaking so the engine has to come apart...
