I hope that mazda comes out with a turbo model rx8. Because I need the most hp & torque available out of my car and because mazda needs to came out with a serios performance car. NA rotary is nice but it really needs the turbo to produce power. I don't think it will make the car much more expensive by putting a turbo

Hercules

I think you should get a different car.

All these power junkies.. makes me wish I lived in Europe sometimes... They appreciate a car that handles well over a powerful car.

BlueAdept

Apparently it doesn't... the RX-8 is more powerful than the Twin Turbo 3rd Gen RX-7... in standard UK trim.

IMNSHO, this car will put others to shame simply by having razor sharp handling... unlike cars like the 350Z which is reported to be nose heavy and have somwhat sloppy handling compared to a traditional european sports car.... You gotta remember, we have more inspireing roads... LOL.

If you want a muscle car, get the 350Z by all means, but there'll be RX-8's waiting at every bend and twisty bit to trip you up!. LOL.

zoom44

drive one when they are available and then let us know if you think the rx8 is a serious performance car. second, please search thru the forum and read all the threads concerning torque and gearing, also look at the graphs of the hp and torque curves that are posted in the threads. that should give you an idea of the power of this car.

The 'Sea to Sky' highway here in BC is all the inspiration i need. The RX-8 will love it.

It's like I say: any car can be made to go fast, so what makes a sports car a sports car? Handling.

BryanH

I think the quote in my sig is appropriate reading for this thread.

I think the '8 will have sufficient power from the factory, certainly. I expect mid-14s in the quarter mile - nothing to scoff at at all, and this is what good turbo sports cars were doing 10 years ago.

No need for a turbo, if you want more power, seek out a 3 rotor engine. There is a post on the 3 rotor, seek it out.

Hey Scorpion,
These others can be happy with their NA engines, there is nothing wrong with that. Meanwhile, you and I can either get the Mazdaspeed version that is supposed to have a turbo and 300 hp, or we can wait for an FE that will hopefully arrive too.

I've lived with a stock Miata for over a year, and I now have a turbo Miata with twice the power. I can tell you from experience that there are benefits of both, and I'm not talking about crap like fuel economy or reliability either.

From what I've heard, Mazda has to build 3 cars on the RX-8 platform to make a profit.

#1:RX-8
#2:RX-7 (take off the rear doors and seats, remove trunk, add hatchback, add additional rotor, shorten car a foot-foot and a half)
#3:Wankel Miata


Adding a turbo (system) is way more expensive than scaling up the Renesis. Sequential twin turbo isn't cheap or emission friendly. Plus the Renesis is a multiple side port engine, doesn't need a turbo or work as well as the previous Wankels with turbos.



For more Ooomph! think supercharger (Lysholm or Inertial) or NOs, or RX-7 (350 hp 250 ft-lbs)

I'd be very surprised to see this. Over on www.miataforum.com Bwob, the father of the Miata, has repeatedly said that it's not going to happen anytime soon. He's still friends with the head of the Miata's development, from what I understand. The next gen Miata is supposed to be under development as a 4 cylinder. I suspect that the reports of a rotary Miata are more along the lines of a convertible RX-8 or FE, which I do expect. An inexpensive convertible like the Miata with a rotary is a long shot, although a 30k+ convertible based on the RX-8 platform is a near certainty at some point IMHO.

I'd love a rotary Miata as well, but there have been too many reports from insiders that it's just not going to happen. Maybe the ND Miata will have a rotary, but that probably won't be until 2010.

Who said anything about sequential turbos?

What makes you say that?

Why do you think that a turbocharger won't help, but a supercharger will?

A single turbo? It could be a light pressure kind, it would be like the MazdaSpeed 2.0, a whole extra 30 hp, better torque. A big *** sized turbo would give great top end, but suck down low due to lower compression rotors. So the solution is sequential twin turbo (have your cake and eat it too)

Parallel twin turbo on a 2 rotor Wankel, I think not, just twice the same compromises as above.

Adding an extra rotor would add about 25lbs, the turbo system most likely would be about double that.

Those side ports have to redirect the exhaust gases about 135 degrees to reconjoin, then go into the turbo. Sure Mazda could design the bends properly and then coat the surface with some insulator to help retain heat.

Isamu Amemiya has applied a turbocharger to a prototype MSPRE with good results, but also a slight loss of efficiency due to a less direct route for the exhaust gases.

So, you say that the sequential setup is the solution, and then dismiss the idea of a turbo because the sequential system doesn't work well...

---jps

MikeW

Sequential twin turbo was the solution a decade ago. Loose emission standards and the use of peripheral exhaust ports allowed the use of sequential twin turbochargers.

I don't think that Mazda will turbocharge the renesis in the RX-8, but they might and would call it a rx-7 (doubtful)

Sputnik

And what does a sequential setup have to do with emissions that a single turbo doesn't?

I don't know why everyone is so outrage by my need to have a turbo car. I'm not comparing the rx8 with any other car or the 350Z. Some of you may not understand the feeling a turbo brings to a car. So all I'm asking for is two models rx8 na and turbo. I agree with with most of you na is nice but prefer the feeling a turbo bring out of a rotory motor.

Hercules

This car has DECENT straight line power. The real benefit of getting this car is NOT the power it's the handling. And that's what we are all eager to see. The MPS will come out with a turbo eventually and then you can get the power that you so 'need.' Most people don't need it, I doubt you do either. Just enjoy the fact that this car will handle better than anything on the road, at least 95%+

Me, I'll be playing with my car in the twisties and on parking lots.

(edited for excessive testosterone, thx RXpecting :D)

RX-pecting

Scorpion:

My advise, hold out for a Mazdaspeed version. If you do, let others buy it and decide then cause there've been problems with rotor and turbo in the Mazda house, I remember RX-7's breaking down @ 60 000 klicks like clock work, so be sure before investing... but keep up the enthusiasm though!


On a related note, I'm one of the relative senior rez's to this forum, although l like to peer more than post, I haven't voiced my opinion here for quite some time now, but coming back here I notice alot of veterans, and I'm noticing some ugly behaviour: some more permanent people here with overinflated self-importance who don't bother to exert the least common decency seem to think it's ok to demean other peoples opinion

I'm talking to YOU Hercules. comments like

''do your stupid stop-light racing like somebody cares. '' (I don't recall his asking you if you cared...)

and others I've seen attached to your name don't fly well in my book. Im not a fan of turbos, but I'm an even lesser fan of people who denigrate others with little or no reserve; you could stand to be a little more tolerant Hercules, alot even, to say nothing of being open-minded.

Just cause flaming is onesided doesn't mean it's not flaming, and I must say, I'm really dissappointed with the way some of these threads are evolving...

There's room for everyone's opinions guys, no need to fight.
Peace

Hercules

Okay, okay I apologise.

You have to understand though, I live in an area FULL of ricers and teenagers and they often try to 'race' my bone stock Maxima like I care.

Many of the comments I get are exactly along the same lines of scorpions. "You need a turbo!" "You need an exhaust!" "It's not fast enough!"

A few of my brother's friends who have driven with me are really amazed at what I can do in my piece of crap cars. Then of course they are like "how did you do that rear end skid!" (being that the car is FWD) or whatever.. and I refuse to tell them because they are morons.

My everyday aggravations come out in the wrong place and I'm sorry for that. But I swear if you rice this car I'll hunt you down :p At least not in my neighborhood!

wakeech

i feel your pain Herc, and i too lash out...
don't worry bro'... they deserve it

seriously though, man oh man, it's like everyone where i live thinks that it's cooler to rice out your car BADLY rather than well... i mean, REAAALLY bad... mild steel wheel arch covers, tacked on... stock exhaust with the cat removed and visually deformed (with a screwdriver, i'm guessing) stock mufflers... or worse still the biggest tips on the crappiest (Civic DX seems to be the hot rod of choice... only the high rollers can afford a CRX or late 80's accord...) Honda's around, not that i'm bashing Honda, but it's the only car they'll use... EXCEPT ON MY STREET!! oh god... i dont' want to whine too much, but some moron down the street had a Neon (not a bad car at first), and proceeded to chop out big squares (with a power jig saw i guess) in his bumper to put amber truck lights... then he got the APC lame-*** tail lights (you know the ones that look like they put together blind folded?? i'm not bashing the style, just APC's interpretation and quality), more auxillary forward lighting, the APC flame-shaped end plates for his POS ricer-wing... then painted it yellow, flat $200 Maaco paint-job yellow (it was better grey)... even his doughnuts, the middles he had painted yellow in a circle... jesus... at least he's serious about it (complete with fake dual exhaust fart-pipe, no effin' kidding :o)... another guy who's only 3 doors down has a late model corolla: blacked out windows, cheap-out-rusted-already fart pipe, and bling bling wheel covers...

<<sigh>>

but gettin' back to the power issue, i really honestly think that to over power the 8 would be to change it's character, and i don't know if i'd like that...
honestly, i really wouldn't mind the 250 it's got... supposing of course i could actually afford one :p

N1XRR

Okay guys, this is where a ball-bearing turbo will be VERY useful. Quick spool(almost like a SC), lots of CFM(larger turbo) and decent durability.

Really? 60,000 mi eh? Yes, FD's had their problems, mostly cause of the twin-scroll system. My turbo RX-7(FC) has almost 114000 miles on the original engine and turbo and its still running strong. A single turbo RX-7 very reliable actually.

Michael

EDIT: Oops, just realised I put twin-scroll in for twin-turbo...FC's had twin scroll for those who don't know

94se7en

Come on guys, thats enough turbo bashing
I have to agree with N1XRR. There really is nothing like a turbo rotary. I'm sure the Renesis will be even better with such a high redline, better breathing, etc. I can't wait. :D

1.3 liter

I will admit, I loved the FD twin turbo setup. I got a chance to drive a '94 RX-7, and that thing SCREAMED! it was the smoothest most powerful car that I had ever driven at that time, but I learned that the turbo set up was delicate. Ironic isn't it Didn't Mazda work out all of the bugs, afterall, the RX-7 was produced and sold in Japan until Aug. of this year. HP was bumped from 255 to 285. I really think that if Mazda turbocharges the RX-8, it will more powerful of course, but extremely durable. Mazda engineers aren't fools, and I think they've learned from their mistakes. If I find out there is a turbo option in the RX-8's future, I will wait for it.

fritts

I am sure aftermarket will offer a turbo option for the RX-8. I do hope though that mazda stayed away from the turbo on the mazdaspeed version though. It would be pretty cool to know that the rotary could produce 300 hp NA. My delimna is I don't know if the next gen 7 will ever come out so I'm getting an 8 just in case this is the last we see of the rotary. I do hope that the when and if the next 7 comes out is is FI though. Nothing better than hearing a blow-off valve go, and hearing a turbo spool up.
