maybe the lost HP is not lost
engine year vehicle disp. hp torque
13B Twin 92+ RX-7 Seq. Turbo 654 x 2 = 1308 9.0 255/6500, 217/5000
MSPRE 95+ RX-01 MulSidPrt x 2 220/8500, 159/6500
13B Renesis 99 RX-Evolv NA engine, 280 HP
Seems the rx-8 and renesis started as 280 hp
then became 250 hp - as touted
then to 238 hp - as sold
and dyno at what? 220hp?
Did Mazda just drop a 1995 mspre into
the RX-8 with 220 hp@8500 and 159T@5500

the mspre 95 was never sold, the numbers are mazda's creation. it is however the prototype for what became the renesis. the path went 220(mspre)-280(rx-evolv)-250(rx8 #1)-238(rx8 #2, which is really more like 220).
the engine was detuned due to emissions regulations regarding the catalytic coverter's lifespan.

sorry if it was double posted, but the webn site must have been slow to show the thread.
I don't think the theory is 'flawed', but it is strange that the RX-8 HP is what themspre was in 1995.
Probably only minor variations between mspre and renesis.

It was aliens, they brainwashed Mazda engineers into putting a low HP engine into the RX-8 as to disgruntle owners in an attempt to shake the world in order to take over all racing events.

Maybe the aliens left the 250 HP rotary in your RX-8!
Mine was left with the 'rotary of the year' model.
Wish those aliens would have reduced the fuel usage when they reduced the HP :D
