its not even out yet for a few months
they are going to tweak it and what not
think about it this way they are making almost as much claimed hp as their tubo rotary in the rx7
one they tweak this, then it only means that another incarnation of the rx7 can come in the future

and mazdaspeed is building a turbo rx-8 for limited production

have you ever thought about the fact that 250 is not to the wheel but to the crank? I mean even s2000 only makes around 210whp.

s2000's make around 199 whp stock not 210

190 whp 2800+ pounds vs. almost between 180-200 guestimated whp but only 2516 pounds. There was one at the 1/8th mile track last night that ran a best of 9.42 with decent launches. I pulled a 9.1 @ over 80, never got to race him though.

I didn't say quarter-mile times I said trap speeds, which are an indicator of HP.
ETs are about traction, especially 0-60.

trap speed hp ratings are never anywhere near accurate. Look at the powerband of the RENESIS engine. With 150ft/lbs of torque, it has a pretty peaky powerband.

I just wrote a five page paper about the new rx-8 for my engineering class. Maybe somebody can tell me what the "three stage, six port induction system" is? I read that in an article but they dont explain what it is. I'm guessing its some system that has one intake port open to x rpm, then opens up another port at x rpm, then has all three open at x rpm?
Oh and by the way, scratch what i said earlier, the engine makes 161 ft/lbs, not 150

I don't know the exact details, but the 6-port intake was introduced on the 13b motor in the 1984 RX-7 GSL-SE.
This is a 4-port manifold:
This is a 6-port manifold (disregard the carbeurator sitting next to it):
There's a valve somewhere that causes the secondary ports to kick on, I think it might have something to do with exhaust backpressure but I forget exactly how the system works.
3-stage I would presume means that in addition to the 6-port system, the intake manifold has some kind of variability to its length kind of like the GSR manifold.
