BTW for the new people the Lemans engine ran for 24 hours
using this full throttle engine speed distribution for the RPM. It
spent 28% of the time between  7500 and 8000 RPM. They disassembled
the engine after the race and could not measure any wear.

Also BTW the Lemans engines is no longer considered a full blown
race engine as some people I know are running them only between
8000 and 10,500. They start were we leave off. The turbo race
people are getting as much as 400 HP or more per rotor.

Well 400 hp per rotor - is that for road race or 1/4mile racing?

I assume we can all but forget about 1/4 mile tech for our application.
Even if these guys run their engines all year, they never do it for more
than a few seconds at a time (at all out power...).

Road/Rally/CircleTrack is a different story, especially if it is long
duration races 6/12/24 hour endurance...

"Still wondering about any difference between the 6-port and 4-port Renesis
exhaust :)"

400 HP per rotor is drag racing.
In road racing the rules are rather restrictive. In most cases
p-ports are outlawed. The guys are lucky to get 110 HP per rotor.
Even at 10,500 RPM. In the 80's the 13B p-ports engines had over 300 HP
They dominated 24 hour endurance  road racing until they were severely
handicapped. They won the IMSA championship five years in a row.

My guess is there is no difference in the RX8 exhaust ports.
