engine year vehicle dis hp torqe
---------------------------------------------
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 engine, 280 HP

=================================
the rx-8 was listed at 250hp
then
the rx8 was listed as 238hp/8500, 159trq/5500
but the dyno numbers don't jive with 238 and mant say its close to 220
so.............
maybe the rx-8 is really a 1995 mspre rotary 220hp/8500, 159trq/5500 verus the 13b renesis at 280 hp evo
maybe at production time Mazda got the rotary off the shelf.

 

Good theory, but I don't think so.
The RX-01 was never tested by an independent party, so those hp claims cannot be relied upon.

 

Ummm.... no. But we really needed another "missing horsepower" thread. Thanks!

 

I believe that was said with a hint of sarcasm.

 

Off the shelf???? The RX-01 was a concept car only. If they produced more than 1, it would be unusual. The MSPRE you mention was a prototype engine to develop the Multi-Side Port design. It NEVER went into production - again, there might have been a couple of dozen produced at most for research and development purposes. The end result of the RX-01 MSPRE engine development program IS the RX-8's 13B-MSP Renesis engine.

Before writing these threads, does no one take the time to notice that the Evolv was a concept? And that its claimed 280hp was the voluntary Japanese manufacturer horsepower limit when the concept was released? Always good to find conspiracy theory in smoke and mirrors.

Maybe I should repost this in Discussion thread, since as G8rboy noted, it appears there also.
