Road&Track test data

______________ 0 - 1/4 mile _____ Power ___ Weight ___ P/W

Toyota
Celica GT-S __ 15.4s @ 91.5mph __ 180 hp ___ 2500 lb ___0.072


A production RX-8’s quarter mile trap speed is similar to a Celica GT-S.

Both cars have high-rev NA engine and manual transmission.

They probably have the same power-to-weight ratio.


0.072 x 3000 = 216 hp (estimated power of RX-8)

Supercharger we have already seen a speed trap for a production RX-8 on these forums in 14.7s at 96 mph. This is very very close to the time slips that Mazda released, and the times a lot of the magazines have gotten.

As for the rest of it, this thread really has gotten ridiculous. Blue 350z wants to believe the RX-8 is a 15 second car. It is somehow important to him to know that it can't be lumped in the same category as his 350z. Funny thing is, for a 15+ second car we have a lot of runs in the mid 14's. Doh!

And if we are going to talk about pure power (ie dynos) then this might make for interesting reading from Mazda as released by RotaryNews.com

Yaw was right, the engine doesn't like dynos. So now we're looking at a car that has dynod 185 or so WITH engine controls screwing the power up. Suddenly things look pretty darned good to me

Of course, Blue 350z will likely insist that this is all a lie, despite independed verification posted BEFORE the release of this information from Mazda. And JFK was assassinated as a part of an alien plot (or maybe he WAS an alien). Who knows? Who cares. The truth IS coming out. Sucks to be wrong, doesn't it Blue?

That's a good one! AHAHAHAHAHAHAH!

aussie77

Hehe thanks. I would have put Blue 350z's name in there instead but at the time he said he was leaving these boards and never coming back.... but once a troll, always a troll.

I posted this over in another forum but was wondering if you guys have read up in this months Option 1, they do a stock RX-8 pull and hit approx. 211whp which is increased to 225ish with cat back.

mikeb

do you mind posting that

White Comet

Ah, dont have a scanner and cant find my dig. cam. lol. I'll take a picture as soon as I find my camera.

mikeb

no problem

WTF no turbo

At 75-80 saw a 350z run a 14.93 does that make it a 14 sec or 15 sec or wtf ever else blue 350 is talking about.Driving skill has a helluva lot to do with it when i get mine up there ill knock that 15 sec outa the park do i get the 1000$?

Rev

this thread is important to me...you guys already have your cars,and no matter what anyone says about them,you defend your car becuase you love it...on the other hand,theres me, a lucky 17 year old debating over either to get a G35C6MT or an RX-8...i have yet to test drive the G35, but i have sampled the Z and RX-8,and they are both wonderful...unfortunetly,while BLUE350z's comments were supposed to glorify the Z,it left me with a bad taste in my mouth...the more i consider what each of these cars are capable of,i can't help but love the RX-8,you guys have painted the picture of a car,with an exquisite gearbox and suspension mated to a superb powerplant that than can propel the car to exceptional speeds,only not speeds faster than that of the Nissan...do i have the right idea here?...i'm no street racer but in the event of a street light drag race with a Z can i expect to lose handily?


also,do you think the aftermarket will take to the RX-8 like it did the FD3s RX-7?or the Z for that matter?

thanks for answering my questions,you guys are great...

Sneakyracer

Yes because they can run 14's all day with drivers of different skill levels. I havent seen a 350z or G35 coupe 6MT run 15's at 91mph all day. Yes I saw one run a 14.9 but at 98mph!!! thats just a bad launch but the MPH tells the tale. 60ft was like 2.6 sec! really bad.

and AGAIN, this thread is about POWER!! and corelating it to 1/4mil or staright line accel performance. (doesnt mean that the car doesnt have other important performance attributes, geezzus. but they are off topic here, seems some people dont know that being off topic is RUDE)

aussie77

In the event of a street race between a 350z and an RX-8 with the 8 broken in, the 350z will probably win. However the two cars are close enough that driver skill can make a difference.

As for the rest of this ridiculous argument about the RX-8's 1/4 mile times. For the last freaking time, we only have FOUR people who have posted their 1/4 times on this website. Two of the four launched at lower rpms which would not give the car peak performance. One of the four did launch properly and got a 14.7s time. Why are people still harping on about having "proof" that the RX-8 is a 15+ second car when there isn't enough data to say that, and what little data we have actually suggests that mid to high 14's is a more realistic number with an experienced driver.

Sneakyracer

Aussiee, your agressiveness is getting really really tiring. why dont you instead contribute something. Do you have ANY dynojet experience? ANY? How about any DRAG RACING experience??? anything??

RX8-TX

Sorry man, but Aussie wasn't being agressive. Just tired of stating the same thing over and over again.

Agressiveness could have been a name calling contest, or some more direct quote to someone. As I said, frustration gets on everybody's nerves.
Chill! (all of us)

RX8-TX

Why?? tell me this, being an average driver, can you even get high trap speeds if you don't do things right? And I mean on any car, even one you've never drove before. Can you get into a Z and get a 100mph trap speed? could you get into anything else and get a std. trap speed for that car?

I would suggest chilling out until we get MORE slips, and see how the story goes. Im really tired of all this sheitzy CRYPTIC PROPHETICAL CR*P (Am I being too explicit here??)

aussie77

You telling me to contribute something is nothing short of amusing. Why don't you try having a little patience and waiting til we know the facts before you go making the statements you have made. If four people drove the 350z and three of them got 17 seconds for the 1/4 mile you wouldn't call it a 17 second car. Plain and simple.

What is getting tiring is people like you spouting the same crap over and over again. You obviously have no understanding of the basic concept of reliable data. I have no beef with that. But when you trumpet your ignorance over and over again that gets very old, very quickly. Four data points is NOT enough to make a statement.

RX8-TX

Hey Sneaky...here you go: this is agressive. Happy NOW?

Sneakyracer

I agree, not enough data. SO why dont YOU take the oportunity you have being an RX8 owner and all and contribute a 5th data point for good measure hu? I would in a SECOND if i had an RX8 just like i did when i purchased my Jetta and there was some small dilema of how much power they made and how much did mods increased power. But as it turned out the initial data was accurate, it was just confirmed over and over.

And yes 1/4 mile TIME is not really a good way to compare cars, there are too many variables (track condition, tires, launch / driver etc etc), 1/4 mile MPH has still variables but it isnt dependent on launch so it tells the truth about power more consistently, and yes even a DYNOJET has variables BUT a lot LESS than any other tests. In my fact my jetta with the same mods as the jetta of a friend of mine in new jersey, 300o miles away dynoed within 2hp of MY CAR, both on dynojets in different locations!.


And agian, I repeat, this Thread is about POWER! not whether the RX8 is a bad car or not.(it obviously isnt) that isnt the issue discussed here.

aussie77

I don't because I'm not in a situation to do so right now. Perhaps if the RX-8's 1/4 mile time was something terribly important in my life I might think about it more, but it isn't so I'm not going to take time out of my schedule right now to go to a track and add a data point to the collection Besides I am sure other people will do so eventually, and I am willing to wait.

I don't see anyone turning this into an argument about anything other than power. It is about POWER as you keep putting in capitals. But it is also about reliable data regarding power. Right now there isn't enough info. Hopefully more will continue to come out

Sneakyracer

Ok, i have been trying to get in contact with RX8 owners here in puerto rico. There arent many dude to the fact that the car costs $39k here (the 6 speed with some options), about the same as a enthusiast 350z and there isnt a lot of dealers that have them. As soon as i contact some i wil try to get some real quality data on a dynojet and 1/4 mile track alongside other comparable cars like S2000, 350z , G35 coupe ,rsx-s, STI, WRX and EVO since i know several people with those cars. 350z has sold extremely well here even at a cost of $39-45k, same with the G35 coupe (at $48k). A RSX-S is about $31k here.

Well see what happens. I, like you and most people here hate to be hearing the same arguments over and over , using the smae information. I will do my part to contribute something new info. I have a lot of contacts in the local tuning comunity here so ill put it to good use.

Fro comparison purposes only, I wanted to post this link to another dyno chart of a car advertised at 225 HP at the crank, that delivering 202 at the wheels: http://www.bimmerforums.com/forum/sh...readid=136301.

The car is a 2003 BMW 330 Coupe. It's interesting that a lower (advertised) powered car is making more RWHP than our "238" HP 8.

mikeb

silver 8
are you serious
you must be new and not been following the problems with dyno's on the 8

canzoomer

Let's stop repeating that mantra Mikeb.

It is simply not reproducible.


I have had NO problems dynoing my 8.

We have taken it out on 2 road runs now with the gear we are working on installed and the results we see translate nicely on the road.
No, I don't have a GTech at my disposal, but the results are clear and obvious.

There is simply no difference in the ECU readings on the road as compared to on a dyno, other than when you do several hard runs on the static dyno, and you see the temperatures rise a lot faster.
The ECU outputs, status readings off the OBD and so on all the same, road or on the dyno.

Supercharger

canzoomer,

Did you take your RX-8 to a drag strip?

Please post quarter mile numbers.

1 BAD TIB

That was a verry good read i have takin in lots of info. just a side note the cars ecm or ecu will not change on the dyno. It suck butt you will always have other car owners that will bash your car trust me i know i get **** talk to me and my tib buddys all the time on THE TIB forum, BUT THE ONLY THING THAT THEY CAN EVER SAY BAD IS THAT ITS A HYUNDAI, the point is is that you guys like your cars and that is all that counts **** the other guys. i have guys in 350,wrx's,gt stangs that talk **** to me all the time all i do is smile and then i smoke ther *** and you guys will do the same just give it time:D YOU ARE STILL DRIVING A BAD *** RIDE
