Yeah but doesn't Mazda suggest to rev at 3K for 10 seconds before you shut off if it's cold (the engine)?

Talk about contradicting yourself (Mazda)...

DARKMAZ8

I have never read this but I'm talking about ppl that do burn outs and rev to 9k while they are idling. 3k is fine.

Dark8

I don't think that applies since you do it with a cold engine.

Frostee

isnt that to prevent flooding though? and only when the enigine is cold?

rx8wannahave

Help us...what shall we do, what...shall we do....runnnnn....lol

I think some of the members here are a little sensative because their 8's have had some work and maybe their dealers suck so bad. I'm sorry guys/gals but at the same time like everyone is saying relax and wait to see what happens.

What does freaking out about it do? Does it resovle the "possible" problem or make things better? Don't worry...be happy...lol

One thing, I really don't see how Mazda should be praised so much. They are fixing a problem they did not detect...that dos not really WOW me. They are covering themselves from possibly major PR problems...heck maybe some lawsuits also.

BUT, don't get me wrong they could have been HONDA like or like FORD...call us when someone dies.

So, Mazda thank you very much for taking care of your customers and product. Give me a ring when you are ready...

With that said, maybe they should figure out how to use "heat pipes" like they do with PC CPU heatsinks. At the same time it's funny to me that such a small engine with so few moving parts is hotter than piston engines but then again it does rev about 3K higher than normal piston engines.

I can't wait to here the news because I have a late 2004 built 2005 RX8.

I guess now I can tell the cop's, if I ever speed, two things:

(1) No, you don't understand...I have to rev my rotary engine to 9K at least once daily so that the engine stays clean. I got to 9K or higher speed because I was taking care of my engine.

or

(2) No, you don't understand...my 8 might get so hot that It might melt the Earth...I'm just protecting everyone else from sun like heat from my rotary engine.

LOL

Keep us posted and thanks for sharing…I hope you are wrong (for Mazda’s PR sake…no car companies like recalls) but so far my 8 has been virtually perfect.

KYLiquid

thanks for the feedback people. makes me feel better.

and yes i did mean electric WATER pump not FUEL pump....oops.

as for this possible recall or whatever, i wouldnt worry about it....I LOVE my car, every morning when my alarm goes off for me to go to work, the first thing in my mind is to get ready to go as fast as I can so I can spend that much more time in the RX8, even just creepying in trafic, I LOVE it, if the mazda dealer wants to take it back for a few days to fix something for free, then they can take it...it just means i drive the truck for a few days, then the RX8 feels that much faster when i get it back :-)

ive never had 1 problem with the car, so anything mazda wants to do to it, as long as it doesnt cause a new problem is fine with me..... I will grab some pics of my '05 built in mid April and post them up later when I get home, it totaly sliped my mind. so if someone can post up an '04 or early '05 underbody we can compare. I guess I will just take a couple pics following the exhaust from the engine bay to the rear.

kinda exciting, ive had the car a little over a month and this will be my first time looking up her skirt! :-)

Racer X-8

Just don't put your nose too close to her exhaust pipe there, KY guy. She might get revved-up and backfire on you 'n' singe your nose hairs right off. :D

Seriously though, I hope this fixes the hot cup holder problem and maybe the breaking heater control **** issue. Heater control ***** control the heat, right? Mine just broke this weekend. Man. I'm thinking of trading her in now.
:p Not!

NMShinka

I'll await further information on this issue in general. However, I suddenly am now a bit concerned over the statements alluding to possible problems in AZand NV. I'm taking a little weekend trip over to Scottsdale this weekend. Should I anticipate any power issues in the heat?

Cheers!

RX-Hachi

I never noticed heat being an issue with my 1st or 2nd gen RX-7s. I don't recall them being that hot vs. my 3rd gen or my RX-8. My 2nd gen was NA and bought new the first year it came out in '86. I never got a recall about anything, never had a single problem with it either. But only kept it for 3 years.

My 3rd gen RX-7 on the other hand did have a recall for the cooling system. The Twin Turbo 3rd gen was notorious for generating heat, most of its reliability woes were due to heat problems. I loved my 3rd gen, but what was really scary was that some had actually caught fire due the heat issues. (In retrospect, the fires seem to have been isolated cases.) The 3rd gen was made right up until 2002 in Japan, so you'd think Mazda would have worked the kinks out by now.

But none of these cars had to deal with today's strict emissions standards, which I suspect may play a role in why the Renesis faces new challenges not seen with previous RX-7s. And with its 9K redline, I'm certain it creates more heat than the 1st or 2nd gen RX-7.

I'm not worried one bit, but I'm very curious to know what's behind it all. The way I look at it, this just saves me a separate trip to get the latest flash (I'm still on M).

khtm

Good point.

And yes, Frostee...that is supposed to prevent flooding. I've been doing it for a bit over a year now with no problems [knocks on wood].

missinmahseven

Rotaries have a longer "power pulse", right? That's where the extra heat comes from. Also the fact that one side of the engine is *always* under fire -- no such thing as a cooling stroke in these.

Heh.. come to think of it, those two factors above is also what gives the rotary it's distinctive song. :D

My 1st-gen ran hot. So hot as to steam rain right off the hood. But you know what? So did my miata :D (neither had that luxurious 'fuzz' under the hood like the 8 does.)

Nubo

That sums it up pretty nicely.

Letter from Mazda.

hmm, from that letter, mazda is just trying to make sure idiots don't kill the 8 due to their stupidity. Who in their right mind would be high-revving their 8 while standing anyway...

Racer X-8

Thanks Dennis. (blurple? )
Would be nice to see those "preliminary repair instructions", and what would "for some vehicles"mean?

ZoomZoomH

and i thought it was something imminently dangerous... bah

NMShinka

I really don't see this as a major issue given the statement about "idling at high revs". I am curious now as to whether or not my Shinka had the heat shield installed. I'll have to "suck up the ol' beer belly" and shimmy underneath, but I'm not suer just what to look for. Is there a way to trace the build date from the VIN? Also, I'm aware that the plant was destroyed by fire back in February; so just how many RX-8's really are "undelivered" at this point?

Cheers!

Sigma

The fire was actually back in Dec and the plant came online again in Feb/Mar so there's been plenty of time for the distribution network to be primed full once again. At any one time I imagine there's easily upwards of 1000 North America-bound RX-8s not yet delivered to dealers, either in Japan waiting for a ship, on a ship, in port in the US, or enroute to a dealer.

Racer X-8

For your build date, open your driver's door and look at the grey/white sticker.

Hey I wonder if the fire was due to an RX-8, idling at high revs.? :o

adrian-1

You callin' me stupid ? Anybody that drag races is going to be reving fairly high at the launch (I usually rev to 6-7k then feather it.)
Other than that, I don't know when you'd be "reving high at idle".

Oh yeah, if your a MAZDA exec and reading this..... I really don't drag race, I'm just trying to sound cool. Plus that video of me drag racing was computer animated.

jowettw

thanks for the PDF!

Racer X-8

"...if the vehicle is parked and the engine is idled at high RPMs, excessive heat buildup may affect..." sounds to me like a somewhat long-duration thing. Key words - idled and buildup. Of course, the japanese have never seemed to master the english language, especially when in a hurry, and the really good interpreter is on vacation.

wedge357

WTF is that about "excessive heat build-up may affect...backup lights" thing???

Sigma

Might have to do with the location of the harness.

yeah i think they are referring to high revving for prolonged period of time (something like 30-40 second nonstop?)
