why im not concerned about hp issues
well 1st off theres the 0-60 times, if they havent changed and the hp issue is just a mess up on mazdas part then whats the problem? we're still getting the car that we paid for with the performance that was expected, we're also getting free maintenance and $500 back, even better! ok that being said heres the other thing, we know that the renesis made 280hp in the evolve so we know that this engine is quite capable of more power strait from the factory. If its because of emissions or ecu problems all the better, easy fix....... I guess no one besides me is seeing the potential of the situation here. As I see it we have a vehicle that before aftermarket mods is capable of 280 hp not to mention the awesome handling capabilities that this car would have with some tien type flex coilovers and anti-sway bars, strut bars.....add forced induction to the mix (as I plan to do ) and this vehicle will be,should i say it ............."untouchable"

Check Rotarynews.com, and then call your dealer. I don't think your dealer knew when you bought the car on 8/11 that Mazda was going to offer the programs, so you will have to ring him and find out what he's gonna do for ya.

i agree with you gr8rx,i ve ran a 15.2 at 90 mph with tires spinning thru all of 1st,2nd and part of third and think with traction or better driving 14.5 is obtainable.still 15.2 is not that far off.i like you see the overall potential of this car,give it a few months and let some tuners uncork this thing with exhaust,intake and reflashed ecu.i bet theres close to 300 reliable hp in this thing.

often, the only way you'd see 300hp out of these 1.3L is a full race setup (shorty headers, straight pipe, big-*** high flow carbs, 10k rpm limit) most notably with a Perhipheral port...
...then again, this latest incarnation of the 13B is making more power stock than most bridged motors.

Different people are reporting 20+ hp by removing that huge beer keg muffler. How do we know that Mazda rated the horsepower of the car with the exact same muffler. Different countries get different parts. I'm not saying they did, but one small oversight could make a big discrepancy. I wonder this because the dyno curves seem to match up to about 6000 rpm or so where Mazda's keeps rising but everyone else's starts to taper off. Any muffler can only flow so much air. After you reach a certain point you are going to have greater and greater resistance. It's just a thought. Who knows though.
On the RX-Evolve engine which supposedly made 280hp, we don't know what rpm that was at, what type of intake they had, or what type of exhaust they had. I had seen numbers posted as high as 10000 rpm on that engine but then again the new Renesis has fuel cut there as well.They could have had a very free flowing intake, more agreesive porting, a better muffler, and better tuning. The RX-8 seems to run very rich. When someone finds a way to lean it out, we are going to see power go up nicely.

It seems sort of unlikely that traction is such a huge issue. 225 mm wide tires are pretty substantial for a car putting 130lbft of torque to the wheels(seems thats the uper range of th edynos i've seen) Or maybe the stock tires are just really bad?
What kind of tiems have most users beein seeing stock at the track? I've seen a lot of low 15s with some high 14s in there.

well it's a combination of two things: the car is geared very very low (because of the very high redline), and the RE040's which come stock are widely regarded as crap performance tyres.

I hear ya. I'm very familiar with the k series(rsxs/tsx) honda tech and my initial glances seem to show the rx8 geared with about 15-17% more agressive gearing than the rsxs.. That's definitely significant...no doubt about it. But seeing as the rx8 is rwd has much larger tires I was thinking it seemed a littler overexagerated. Then again i haven't driven one :D

My understanding of the 280hp in the RX-Evolve was that it was only a target. And 280hp, at least then, was the voluntary maximum hp limit in Japan. Following that logic, the Evolve was only a concept, and the real power of the Renesis was not a factor.
I'd like to believe the Renesis can make between 280-300 as a NA engine, but I can't see how that's possible.
Someone correct me if I'm wrong.

An ET of 14.5 is VERY difficult to achieve on a 90 mph RWD car. I'd even venture to say it's impossible for a 90 mph car on street tires to run a 14.5 second quarter.
Finally, traction will help the ET more than the trap speed, so even if there was a traction issue, which I doubt, I wouldnt expect to see a significantly higher trap.
FWIW,
