(I'm just looking at the data posted here. No one has posted any numbers to the contrary, only subjective comments about how the car feels fast enough for them or that the car meets the gas millage when they drive slower than grandma).

HOWEVER - this is the internet, don't believe everything you read, and consider the sources of what's written.
ALSO - you obviously haven't read everything here. I personally have posted my fuel economy numbers for a 6600 km road trip from Calgary to Monterey (11.8 L/100km average, or 19.8 miles per US gallon, high of 23 MPG, equal to 28 MPG Imp.), and as I already reported, I certainly wasn't granny driving at any time on that trip. My car doesn't fall flat at 7K rpm, but has a nice kick from there to 9K. My AC is cold and doesn't cycle. The real tests like 1/4 mile times and trap speeds show that the car is delivering the performance that was promised, despite whatever results are turning up on private dyno tests. Those are objective measures. Subjectively? It's as fast as I expected/hoped for, and I am extremely satisfied with it. My only issue is with the floor mats with the hole in the wrong location (Canadian cars only), which certainly isn't a big deal.

Please note that I did say specifically "11.8 L/100km average, or 19.8 miles per US gallon" for the overall average.
The highest mileage I acheived was about 23 MPG US, which is equivalent to 28 miles per Imperial gallon.

Road & Track that came out recently, had a list of all the new 2004 and the RX-8 came up saying 207. I'm not exactly sure what the #s are for auto/manual, but this is showing that atleast one mag is now showing the real power of the RX-8 right?

If they mean at the crank, it is a bit lower than what even the pessimists are saying.
If this is supposed to be at the wheels, it is higher than what anyone has reported.
Maybe they picked that out of a hat?

3 fellows on the Canadian east coast did a dyno test tonight.
See this thread page:

Best was 168hp, and one, with lower mileage, made 158hp
ouch

The car is fast. Faster than most on the street. My buddy and I took our cars out tonight for a test to settle our debate. He has an 01 Vette with CAI and Borla cat back exhaust which, for the dyno reading geeks, would give him about 370 hp or thereabouts. Stock I hung with him without trouble on the freeway but expectedly he killed me on rolling starts but the story was different from a dead stop. Until I shifted into 3rd he had no chance at all. The 8's problem is not in the low end, (which I haven't heard or read any complaints about) it's in the middle of the RPM range. Ofcourse I was down alot in the hp compared to the vette and down in torque on the upper end. But then if I'd have spent 40K on a vette I wouldn't be here typing right now. I'd be sending thoughts by snail mail and recycling cans to make my payments. But don't be fooled by nay sayer and dyno's this car will keep up with much more expensive makes. I easily stayed with a Z7 a few days ago in La Jolla and he was trying to lose me up Torrey Pines. I'd be pissed if I paid that much for a sports car and couldn't totally smoke a car that cost less than I paid in taxes on mine. I'm more of a "seat of the pants" driver when it comes to speed, it feels fast as **** off the line but just fizzles when you need to close with the big boys at the strip. Besides, drag strips are where these things issues are decided; not dyno's right? I don't give a **** what the computer says. The car doesn't drive itself on a roller in a vacum environment. I'll be taking my digicam out to the track and street with me and I'll post just how slow the 8 is when the chips are down, that's the true test anyhow. I'm sure this car will come alive with a header and exhaust system and a CAI. So maybe 3K in parts and you can get what you feel you've been slighted. If you were looking for a the fastest car on the street you should've looked elsewhere and expected to spend more money than you did if you have any sense at all. It's fast for the money and it's damn good looking and I don't know about where you live but here in SOCAL it's still a rarity to see on the streets and it gets lyou ooks like you're in a Ferarri and when the road gets twisty it goes like mad, in fact better than the vette and with way less drama. This is not the first time I've had it on the streets with the vette and nobody even notices the vette when we're out. And I can have 3 friends along for the ride. Does it have quirks.... absolutely. Does it have power deficeits...... yes. Can it be modified to a fire breathing street slayer.... you bet. Just give it time. You can make anything go as fast as you'd like by throwing money at it if you're so inclined but this car is an excellent starting point for street tuners and it's got looks....... man does it have looks. RSX is as ugly as they come, I'll give the S2K props, it's one pretty car and a drop top to boot but still not in the same category as the 8. It's sensible performance folks, that's just not found anywhere else. RWD with near perfect handling and all the creature comforts for not much money if you know how to shop. Where's the competition?

Also, I don't think the S2K is pretty...its darn functional, and even in some ways slick (I think the 8 got the final touches the S2K is still missing -from a style perspective). Small tires, mid-sized chassis, and wide stance: little compromise between comfort and performance; are all qualities the S2K has to offer.
But at the end of the day, the 8 suits me better.

That equals from 202 - 209 Crank HP assuming a 17% drivetrain loss. Using Mazda's figure of 238 HP that would be about a 27%-30% drivetrain loss. The difference between this and many of the others (done at 93 octane I think) is about 5- 10 WHP, which seems to make sense.
There is no way this engine is spitting 238 HP at the flywheel or that carbon fiber drivetrain was one big waste of money!! These numbers all seem to be consistent with my view that the RX8 felt about as fast, if not a bit slower than the RSX Type S and Celica GTS.
