8's cant make power because their all running the same internals;
We all have the same rotors, displacement, port configuration.(mostly)

Mazda is the only rotary production car, no parallel competing development.
Imagine if you could go to the local speed shop and buy new higher performance rotors by TRW or a new design ported rotor housings by Edelbrock, remember most of the "factory" high power options we have in V8s came from the after market first.

With only Mazda making rotaries, there is no drive for after market manufacturers to do any performance re-engineering.
I would love to see lots of different companies make lightened rotors out of say Titanium, Ceramics, "Unobtainium" or something, or make their own design of housings with giant ports for the Mazda engine.

What do you mean you cant get power? HAVE YOU SEEN MY CAR? ALL THAT FOR LESS THEN 2.5K FOOL.

What! You want a 55lb motor?

That'll work for me!!!

No, seriously, only Mazda makes the rotary internals.
That is bad for any incentive to develop more power.
It would be cool if some of the companies that make after market bolt-on heads for V8s would make higher flow housings for the rotary.

....I wonder if you can offset grind an eccentric shaft for more stroke and compression?

How about hub motors for the front wheels powered by supercapacitors?

Have them only engaged at low speed (so you don't need gearing) for low speed traction and acceleration. Use regenerative braking as well as the alternator to recharge the supercaps. You could even have a mode where they move the car at low speeds without the engine running, so you can move the car short distances without flooding risk. You might even do the hybrid trick of shutting off the engine when idling, so (along with the regenerative braking assist) you get better mileage.

And lighten the load some. Look at the Lotus Elise, 0-60 in 4.9 from 190 HP.

Also, Mazda should look at TRD. Performance add-ons covered by the factory warranty would be popular.

lol? You mean mazdaspeed right? Oh wait... they already make add ons covered by the factory...

With the standards of today, it's tough for them to cut more weight in an effort to keep the care extremely safe. I mean, look at the S2K. That thing has no business weighing in at 2800 lbs.

Since they don't offer more than a light flywheel and a CAI to speed up an -8, I have a mental block against them... yeah, that's it...

or coilovers sway bars strut bars brakes exhaust short shifter... I guess since those don't give you HP that you really shouldn't count any of those as to making the car better...

Your argument is flawed from the start. The reason why the TRD parts make more power on those cars is because at heart they are econoboxes. The RX8 is made as a sports car, which is why you don't get as much power from bolt ons. Those cars benefit more because they aren't even close to being maxed out whatsoever, which is why these companies can continue to make a buck or two on these accessories. If you want to bring up the supercharger for the TC I really recommend you read the fine lines on that before you say anything, I worked at a Scion dealer and saw the hilariousness. It's not even a remotely fair comparison from the get-go.

I guess HP really is all that matters to some people. I suggest you don't bother posting on here and go directly to 350zclub or some Mustang club in order to get yourself wet over power numbers alone. You really are missing the entire point of owning a true enthusiasts car to begin with.

I suppose if people are interested in building dyno queens then they bought the wrong car and Mazdas are not typically friends of the Dyno.

Performance numbers are important because it helps gauge how effective modifications are and overall I prefer to know what kind of power I'm putting down but there are so many other factors at play that the motor making peak power is just one piece of the puzzle.

Back east I had to school a kid as to why his Mustang Cobra lost a serious race due to the fact that about 90% of his motor had been chome'd out. I told the moron to go weigh his car sometime! He didn't understand with tons of horsepower how a simple mustang GT had roasted him.

I want a Turboniques 1500 HP drag axle on each wheel and Aux pocket pods.

The Toyota Supra HV-R uses wheel motors like I described, if you're implying my thought is a pipe dream. Granted, the HV-R is a race car and thus cost may be a major issue.

The default handling, ride, and braking of the RX-8 are all very good in my estimation, and I would be reluctant to mess with them. Those also tend to be something a small third-party could do, whereas who among us would buy a used RX-8 with FI? In most cases, we'd be too concerned they did something wrong. The Mazda stamp of approval would be worth much.

Dude... Also... just read the whole thread... and I gotta say owning an RX-8 is new grounds to me. my last car was a 2007 hyundai accent... a 1.6 engine so bottled up for gas mileage... that EVERY LITTLE ******* THING you did... made a difference.... Short ram intake... OH MY GOD what a difference... Bosch spark plugs? Its like I'm running nitrous... Full exhaust WHOA WOCKATOW thats fast....

But... I still traded it in... because... I'm a driver. And I wanted a drivers car.
And the RX-8 delivers. period.

Smoogle... ya'll take life too seriously...

I can kinda see the veterans points though... Just a shame there isn't any new news coming in about the 8... Probably gets irritating after awhile to see the SAME DAMN thing covered over and over and over... as new people get the 8... (I asked a few dumb ones myself)

It'd be nice if maybe, you saw a LEGITIMATE post about someone finding a new point to our car that noone ever knew...

For the veterans... they probably find themselves thinking... why do I even sign in anymore...

You don't have to go longer than to the Mazdaspeed MX-5 to see how cramped the intake and exhaust can be on a car by default. Flyinmiata's modifications gives you plenty of more rwhp on that alone.

Doesn't seem to be the case on this car

The primary issue is this forum contains an absolute wealth of information about the rotary, discussions about it's good points, and it's negative issues. You'll find that many of the people who are involved with the rotary community are also large automotive enthusists that believe learning and understanding are rights of passage.

That being said, simply insisting that people spoon feed you knowlege just because you asked for it isn't going to cut it. People want to see you did your homework and understand at least the basic concepts.

I'll try to avoid beating a dead horse here...

Coming online and asking "how much boost can the rotary handle, I wanz a turbo kit" is a red flag for anyone with knowlege of turbocharging or FI in general that this person doesn't have A CLUE and wouldn't understand the response even if someone was to give it to them.

RX8club has a lot of members who know just enough to be dangerous.

The high performance section has pages and pages of information produces or reprinted by members on issues such as this thread. We're re-inventing the wheel. Besides, to say the RX8 doesn't make any power is a false statement in itself. With the proper setup, 300+ whp is absolutly possible with 350 whp being within reach.

My guess is that people asking such questions haven't handled a vehicle with this much power. A friend of mine with a 500 WHP RWD vehicle complains all the time how much of a hassle it is to drive that car on the street. One wrong step and you spin out from loss of traction. I know 300 < 500 but the point is the assumption is more power doesn't mean having more handling problems.

WHP doesn't make or break your vehicle to begin with. I attended a novice Time Attack race yesterday and performed MUCH faster than a 2003 Cobra Terminator, a Honda S2000 (by over 10 seconds faster), a couple 350z's and a G35. All of these owners would no doubt have told me they would have smoked me prior to the race.

If you're interested in performance, who cares how much WHP you have as long as it gives you the performance you want.
