Fuck a RX-8, Mazda Furai
 

I don't understand why they don't put a more powerful engine, like this one, in their "sports car"

Sounds a little crazy, the original concept had an all glass roof. This one has a 3-rotor 450hp wankel.

Looks pretty damn weird but I dig the flat black.

Re: Fuck a RX-8, Mazda Furai
 

you mean the new rx7 AKA the rx9?

o, hm... thats for the 16g.

Re: Fuck a RX-8, Mazda Furai
 

No, I mean the slow ---- RX8 they have now. The RX9 is just a rumor with a few photochopped pictures floating around and a speculated 2012 release. This is a completely different vehicle that's supposed to be in production sometime and they already have working prototypes (as you can see).

RX7 was cool, RX8 was kinda disappointing IMO. Friend's brother bought a brand new one and it wasn't that impressive although he thought it was the ----. It was rated at 240hp (or around there) and I remember reading a couple magazine articles talking about how they dynoed at less than that.

If the rx8 does come out, it'll probably be a sporty sedan while this thing becomes their sport vehicle.

Re: Fuck a RX-8, Mazda Furai
 

did iq's just drop sharply when i was away?
the rx8 was nothing more than a platform for the engine.

and the engines do actually make that kind of horsepower. you cant actually measure it unless the car is moving cus it can tell when its moving or not, so it throttles the power down. it thinks its doing a burnout so to speak.

i was recently at downing atlanta where they had a stock renesis engine in one of their race cars. fully tuned with a motec stand alone it was runing about 280 HP. that's Bridgeport territory. and to think, it was just a stock engine.

this is just a race concept. nothing more. you think they will have a green 3 rotor renesis engine making 450 wheel HP runing the streets?

no

this thing doesnt even run on gasoline.

Re: Fuck a RX-8, Mazda Furai
 

I don't know, has your IQ gone down?

DSC can be turned off so the sensors would have no effect on "tuning down" the engine on a dyno. I highly doubt magazines are going to risk their reputation by pissing off mazda enthusiasts by not doing something that takes a few seconds.

Did your reading comprehension go down or do you just not have any?

Please show me where I stated they would use this exact engine and setup in a production vehicle. I am aware they can make more power (O RLY?!), I said they should put a more powerful engine in their "sports cars" and I bet whenever this goes to production it will be faster than the RX8 they have now.

Re: Fuck a RX-8, Mazda Furai
 

I dont believe you, I think you're lying

Re: Fuck a RX-8, Mazda Furai
 

shhh don't tell.

I know this sportier looking vehicle will most likely get a slower, weaker engine

Re: Fuck a RX-8, Mazda Furai
 

last i remember mazda had to allow customers to return the rx8 if they wanted cause of false advertising.
mazda said it makes x amount of hp and that was a lie. customers had a certain amount of time to return the car.

Re: Fuck a RX-8, Mazda Furai
 

I seen some Bolton rx8s dynoing at 180hp while smelling like ----

Re: Fuck a RX-8, Mazda Furai
 

o snap i knew vin diesel was on this board....i knew it!

and 280hp.....big whoopty ------ doo.....that motor should have been pushing 280 factory tuned. Mazda dropped the ball on that fucker....oh yea....don't forget that if u do own a rx-8...mazda will tell u the motor burns oil because thats how they built it so u have to continously add oil.....what kind of shyt is that......RX7>RX8

Re: Fuck a RX-8, Mazda Furai
 

Well the oil consumption is legit, it needs a little oil fuel mix. Although I believe you could disable it and premix the fuel if you want (it not much oil)

Re: Fuck a RX-8, Mazda Furai
 

the rx-7 had that too, its called the oil metering valve.

if it ever failed, your engine was fucked.

Re: Fuck a RX-8, Mazda Furai
 

bravo, we do have some smart people here.

the oil metering pump from every RX car to the 1988 series rx7's where all mechanical. everything above that was electrical. mazda tried to fix this with ecxu controlled pumps, but they are iffy.

280 wheel HP is ALLOT of fucken HP out of a 13b.

170 to 180 is faster than a 2nd gen turbo II.

but like i said, Mazda didn't even go for much performance here. they wanted to test the platform. that's it and that's all. they weren't attempting to cary the lineage of the rx7 or anything. if it was slow, they didn't care.,

Re: Fuck a RX-8, Mazda Furai
 

Oh, so that's why they overstated it's power ratings? We aren't talking about "MOTEC tuned" bullshit, we're talking about a stock "240hp" engine that rarely, if ever, dynoed anywhere near that (with DSC off).

If I wasn't going for performance, I would under-rate it.

Re: Fuck a RX-8, Mazda Furai
 

some engine actually have made those numbers. the problem was loss of compression due to the bad oil metering pumps.

Re: Fuck a RX-8, Mazda Furai
 

Well, I wish they would get inherent flaws worked out of the rotaries. Theoretically, they seem like a great idea, but piston engines top them in about every aspect except rpm, which short stroked engines can still top).

Re: Fuck a RX-8, Mazda Furai
 

I agree. Especially NA and stock port.

Re: Fuck a RX-8, Mazda Furai
 

i loved the weak power plant found in my 83 rx7 gsl. 12a just has no balls when it comes to torque, but i loved the powerband it had. just cruising, if ya punched the gas you could feel the lsd workin. to bad i blew that bitch. now the 7 is sitting awaiting some type of engine to be put in. ive had thoughts of a high hp chevy V8(which is in the last steps of building on an engine stand), and my dad tossed me the idea of putting in my 5 speed from the old v6 TA motor on the back of a turbo "Iron Duke." Which im beginning to like the sound of.

Re: Fuck a RX-8, Mazda Furai
 

mazda = junk .... anyway you look at it

Re: Fuck a RX-8, Mazda Furai
 

I saw two rx8's with full boltons dynoing before me when i had my 300zx like 2 or 3 years ago, right about when those cars came out, and If i remember correctly they made about 170-190 hp with a tune, intake, and exhaust. That car was underrated. I dyno'd right behind them and made a solid 298hp 299tq. The dyno was a mustang dyno, so maybe at 10-20hp on top to equal a dynojet, but eitherway those cars suck ass. And mazda hasn't came out with anything good rotary wise since the rx7. Although the turbo miata was pretty neat.

Re: Fuck a RX-8, Mazda Furai
 

Well, like he was saying, the traction control will make the mixture go rich if it senses the rear wheels moving more than the front, so maybe that's why they didn't dyno well or smelled like ----. Either way, yeah they don't dyno what the factory says. Despite the homo that miatas scream, I wouldn't mind an older one if I could find one in decent shape and decent price. An LSx swap would be nuts if it wasn't too big of a PITA, or the regular engine boosted would still be fun.

Re: Fuck a RX-8, Mazda Furai
 

ah i love the rotay debate. if you dont like them, ok. if you do like them great. any way you look at it, it doesnt matter what you think till you have driven them. they are alot like an EF in that you hate it for all the flaws, but when you sell it you miss it, and when you get back in one you remember why you bothered with them at all. there not cheap, they arent as easy to make power, and they arent (debateable, but only by someone who actually keeps up with the maintanance) reliable. but there is a cult following of the rotary for a reason. as i said before, its a thinking mans engine. if you know what your doing, its an awesome engine, doesnt really matter what platform its in (but it does help not being an rx8), it will go and be much more fun than a piston engine.

Re: Fuck a RX-8, Mazda Furai
 

yeah. like i was saying, the numbers have been all over the place. there have been people report sub 100 numbers, sub 200 numbers, and even sub 250 numbers.

the driveline saps up a ton of power.

when the first 2nd gen came out with 160 hp, it only would make like 120 at the wheels.

Re: Fuck a RX-8, Mazda Furai
 

That looks like it should be the new bat mobile. Oh yeah the new bat man comes out in July woot

Re: Fuck a RX-8, Mazda Furai
 

it looks like a running shoe.

Re: Fuck a RX-8, Mazda Furai
 

hmmmm

i'm installing a turbo on one tomorrow night, maybe I should post a video of the test drive.

Re: Fuck a RX-8, Mazda Furai
 

what turbo is it?

Re: Fuck a RX-8, Mazda Furai
 

The RX-9 is nothing more then an Internet rumour. If Mazda every did make a new RX-7, it would still be called an RX-7. And I don't have a lot of hope for a new RX-7 anytime soon.

That would be 16X. An experimental direct injection version of the Renesis.

What's wrong with standalones? You'll find almost every high horsepower rotary running either a Haltech, Microtech, Motec (Motec is gaining ground these days), Tec, Megasquirt, etc. Fuel and ignition control are critical and these can only come from a full standalone. Personally I run a Microtech LT8s.

Out of a 1.3 litre, 280 HP is pretty good. The old twin turbo REW made 255, then was upped to 280 late in the production run.

Keep in mind that production engines must do things like give good mileage and burn clean. As odd as it sounds, generally tis means running richer then it would be tuned for in a performance application. While this keeps NOX low and keeps the cats happy, it costs power.

"Continuously" is a bit of an exaggeration. The rotary needs oil to lubricate the apex seals. This oil is supplied by the metering oil pump and burned as part of the combustion process. The older mechanical style pumps would burn abou 1 quart every thousand miles. The newer electronic pumps (which the RX-8 uses) have cut this dramatically to the point where you top up every 3000 miles. It's not that big of a deal.

It's called a "metering oil pump".

The mechanical metering oil pumps just don't fail.

The electrical pumps will fail occasionally, but the ECU will put the engine into limp mode to protect it until the pump is fixed.

'88 RX-7s were still using mechanical metering oil pumps. The switch to electronic happened in '89.

The electronic pumps are slightly less reliable then the mechanical pumps, and occasionally they will fail like any other part. However on the whole, they are very reliable.

The S4 TII made 180 HP. The S5 was 200. A 180HP RX-8 is a lot slower then a 200HP RX-7 due to weight.

Nothing to do with bad metering oil pumps. Without going through the whole story, Mazda screwed up on the firmware. The first software would flood the engine, so they leaned it out. The 2nd would kill cats as it was too lean, so they richened it up under cruise. Which cost power and caused other issues. They have no released several different firmware versions and the problem is basically fixed but the engine is still downrated in power from the original literature. I think they are ECU version "M", but can't remember for sure.

Mazda dominated almost every form of sports car racing in the 80s and 90s thanks to the RX-7. They also won LeMans outright in 1990. RX-7s are well built cars, very solid and overbuilt. They are highly reliable when maintained and respond well to high power setups.

Statements that they are junk are ignorant and just plain wrong.

S4 NA = 146HP
S4 TII = 180HP
S5 NA = 165HP (or 160HP, I forget)
S5 TII = 200HP

Re: Fuck a RX-8, Mazda Furai
 

Greddy kit. Didn't quite get it done last night. It's a ------- tight fit. Got the E-manage Ultimate installed, turbo & oil lines installed, and about 3/4 done on the intercooler & charge pipes. Need to put in the down pipe, intake pipe, and reinstall all of the factory ----. This dude is loaded, it's an '07 RX8, he's had it for a year, and it has like 1900 miles on it (and an Agency Power exhaust).

I guess the guy's brother found out he got the turbo setup and ordered a bigger turbo kit for his RX8 and wants us to install that also.

Re: Fuck a RX-8, Mazda Furai
 

arron, what made you migrate over from the soft side at rx7club to the harsh side of the internet such as homemadeturbo?

Re: Fuck a RX-8, Mazda Furai
 

Well, he's not spouting bullshit so should be "safe" here.

The ones that come here asking if they can turbocharge a naturally aspirated engine are the ones that get dry raped

Re: Fuck a RX-8, Mazda Furai
 

ha ha ha. hes the one who actually disproved everyone on rx7club that said "you cannot turbo charge a NA"

Re: Fuck a RX-8, Mazda Furai
 

Originally I just wanted to share my Project Tina. I don't plan on posting much here. Occasionally I will pop up in a rotary topic.

Re: Fuck a RX-8, Mazda Furai
 

ah ok. i ddi the same thing you did, except i just thew na rotors in a t2 block. s4 na to be exact. i had kahren build the engine for me.

Re: Fuck a RX-8, Mazda Furai
 

Yeah, uh, not quite the same thing as I did. :)

Re: Fuck a RX-8, Mazda Furai
 

Apparently F&F wasn't as big a joke in Canada, judging by some of the Frog CRX's on here at least.

---- you, it isn't 1.3 liters.

Kain you're a failure.

Re: Fuck a RX-8, Mazda Furai
 

how so?

Re: Fuck a RX-8, Mazda Furai
 

Kain... where the ---- do you live? I need a turbo RX7 to take a bunch of parts off (rear end, engine, trans, cluster, ecu, etc) for my crx. Help a nigga out.

Re: Fuck a RX-8, Mazda Furai
 

You paid someone to build your rotary.

Failure.

Re: Fuck a RX-8, Mazda Furai
 

yeah, im such a loser because i dont want to source all the parts such as the irons, ecc shaft, and rotors myself.wait, what??
