2004 RX8 most RWHP !??
 

Hey there,

I just read that the 2004 RX8 (that I own) has the most rear wheel HP because Mazda detuned all those that followed. Is this true ??? Anyone know for sure on this ? Anyone have the numbers of the more recent years ? I'm thinking of getting out of my 04 and into an 07 for instance and am curious if there's a difference.

Thanks !

I think there was something back then about Mazda claiming it had more HP than it really did. I don't remember exactly but I think they said it made like 250HP but after dyno's they showed not to be making that much and so Mazda stated a less HP number going forward.

That's all it was. Mazda came out with refined numbers after dyno's determined it wasn't making what the marketeers originally claimed. 2004 - 2009 all have the same Hp ratings (MT and AT discretes of course).

Sorry, your 2004 is just like everyone else's. ;)

lol ... Actually I'm happy to hear that to be the case because I'm looking to get a new one (like an 07) and want the same experience.

So this is DEFINITE, all manuals for instance all have the same rear wheel hp 2004 - 2009 ?

Yes, same horsepower, although the 2009 did get a slightly different final gear ratio.

Ah...does that different gearing make the 09 quicker 0-60 or higher total speed ?

Thanks btw for the info !

I kind of find it strange that the rx-8tu offered nothing more than a few body and interior options where as the 350Z offers the Nismo and Mustangs come with like 4 different engines and suspension setups.... even the RX-7 had 3 different options with suspension upgrades (if I remember correctly).

some 04's have more HP but that's because they have FI!!! haha

you guys gone soft or something ? Came in here expecting to see a flamefest .

A little more torque in the low end, but it doesn't ultimately improve the 0-60 or top end. We have to await the 16X for a dramatic improvement.

'course in the mean time you could throw $7k worth of FI at your '04. ;)

same here but i think they let it slide because he didn't ask, "who here has the most HP? my friend has a supra 2jz with 3,000 hp to the wheel with only a chip, is that doable?"

^yeah that's true....I don't flame too much as long as it's not a dumbass ? like "eBAY turbo kit...500 bucks makes 600HP should I buy?"

they also changed how car companies determine horsepower so that's why the numbers are different after 05 (?)

US flame someone?! nooooo.... :FIREdevil
