Horsepower Chart
Ed,
This is the only chart I have seen that shows
flywheel HP. I have seen two or three rear wheel dyno charts that show
between 190 and 204 hp. These where with aftermarket exhausts and intake
filter. The 204hp was running a Mazdasport Interceptor ECU. This dyno
chart did not show rpms but showed MPH. I found one chart that showed peak
hp at 178 at 7300 rpms. This was a stock RX8 no mods at 500ft elevation.
Racingbeat's test show 8 hp improvement by removing the catalytic
converter regardless of muffler and 2 hp by improving the intake.
So 204hp seems like a reasonable number with modified exhaust,
intake and an aftermarket ECU. Any swags as what the HP loss
is to rear wheels?

Correct in what sense, Bobby?
It looks similar to charts I saw early on by Mazda
showing the output of the Stock Renesis to be 250HP. The
trouble began, when other folks started putting the
Renesis on dynos and could not get that much
power. Mazda later revised its HP for the Renesis downward to the
235 HP level at 9000 rpm.
Remember you can peak and tweak a dyno installation
to get numbers that you would not normally see in operational usage.
Others out there with real dyno experience can verify this.
FWIW
