"drag limited" means that the aero drag from the car moving is what prevents it from going faster in 5th. you'd have to make the car more aerodynamically efficient, or a lot more powerful to get it to a higher top speed.

yes, if a "higher performance" chip was available, it would help a little.

Dear Buger,
GET A LIFE!!!!!!!:D
So you're saying that the RX-8's top speed is 186mp/H? That makes it out to
299Km/H (If Miles are statute)
or
344Km/H(If Miles are Nautical)

Please keep in mind that the Enzo Ferrari does 350KmH
I'm probably reading this damn thing wrong, but can someone please explain it for poor teenagers like Unemployed Pimp and my good self?

Buger

You're right, maybe I should get more of a life and not post here so much.

If you will look at what I posted, I clearly mention that the top speed is limited by aerodynamic drag to approx 155 mph?

I thought it was clear when I mentioned:

5th gear ... 157/253 but drag limited at approx 155/249?
6th gear ... 186/299 but drag limited at approx 150/241?

unemployedpimp

yeah! buger why do u think that i asked if we can make the rx8 go 186mph with a chip or something?

Within the article C/D did when comparing the RX-8 with the G35 Coupe & the Ford Mustang Cobra, this is what they observed during their 3 day test

Top Speed:
Mustang -- 155 mph (Governed)
G35 -- 155 mph
RX-8 -- 144 mph

The article did not specify if the limit was drag, and it did not list it as governed, like they did with the Cobra.

I ran the numbers myself. I used 804 revs/mile (thanks tire rack)

If you did something stupid (and fun) as dumping the clutch off the rev limiter in first, by the time the engine gets back up to 9K in first, the rears would still be slipping about 10-15%, so the actuall speed of the car would be less than indicated on the speedometer (unless the speedo was low value tied)

Tire slip in second, that was just wishful thinking.

Thanks Mr. Buger


No more zoom-zoom-zoom, time for ****-****-****.

wakeech

i know you guys have this personal vendetta going, but seriously, did you watch the C+D video?? the tyres clearly chirped in 2nd...

Buger

What tire size did you use to get 804 revs per mile? If you ran the numbers yourself, you either had the wrong tire size or made basic math errors. 225/45R18 will give you 776 - 777 revs/mile no matter what site you use?

Below is from: http://www.tirerack.com/tires/tiretech/general/size.htm

To figure the outside diameter of a tire, take the sidewall height and multiply by 2,(remember that the diameter is made up of 2 sidewalls, the one above the wheel, and the one below the wheel) and add the diameter of the wheel to get your answer.

Example...185/60R14 85H or 185/60HR14

185mm x .60=111mm x 2=222mm + 355.6mm(14")= 577.6mm or 22.74"

So you are saying that the RX-8 tires will never gain traction in first gear if the launch is high enough? Where do you make this stuff up?!?!?

Why is tire slip in 2nd gear wishful thinking for the RX-8?

Hi Wakeech,

You might want to read the context of the thread again. I didn't say that the the RX-8 tires will not chirp in 2nd gear.

For tire slip to have any impact on the top speed in gear, the tires will **still have to be slipping thoughout the entire gear and still slipping at redline when the shift to the next gear is made**

MikeW's contention that the rear tires will **NEVER gain traction thoughout ALL of first and second gears** is quite ridiculous yes?

It's like every post of his is an attempt to act like he knows something but they are all filled with unbelievably glaring examples of misinformation and errors that no respectable intermediate school kid should make.

Making mistakes is no big deal but when somebody who is completely clueless goes around spreading misinformation for the sole sake of trying to "sound smart" and impress people, it is ridiculous.

What if you turbo the rx8 would it reach a higher top speed since its not govern speed limited but drag limited

ken-x8

Yes. Top speed is usually a balance between horsepower and drag.

Sometimes it's a balance between drag and traction. Some time read up on the exploits of the folks who run at Bonneville.

Top Speed is fast enough that you can't handle it. More importantly is how fast can it reach its top speed.

Aseras

I've gotten my rx8 into the 160's. maxed 5th at 151 mph. handled decently on a flat straight road.. felt a little light.

Aseras

if we are just talking about spinning the tires, if i flat shift, i can easily break the wheels loose into 3rd gear and chirp 4th.

marvin_rock

That c/d article CAN'T be true about our top speed unless it was an auto (maybe) you can see a video of ME doing 140 in my stock engine rx-8 (I've added nothing but weight to it thanks to audio system) I hate to link myspace, but I don't know the link directly to the video - http://www.myspace.com/marvin_rock - it's the third video down I think, the one with the yellow text or whatever. That's all I have to contribute as I don't know much about cars and what not cept I love mine!

d23

my 4th gear ended in 120 sumthin mph.. anyone got the same issue?

zenmoused

The last time I pushed my car was on this beautiful stretch of empty highway in NC. My friend was down from PA and was riding in the 8 for the first time. So I floored it through every gear.. up to the end of 4th. The rev needle was acting like it hit the governer. I'm of course livid that this perfect run was messed up and wondering what the hell was happening.. turns out the cruise control was still on. So in case anyone out there doesn't know, 120 is the fastest you can go in cruise.

Aseras

4th on mine is good to 135ish

zeblien

I have an auto 2006, and it goes faster then 145mph. I had to stop at that point and slow down.

Aseras

that's good because the old auto's were governed to ~125 mph.

zeblien

ROFL! I would not have got the AUTO if it wasnt a 6speed. I always have a Sonic Cherry and Lime 44oz cup in my hand, so a manual is not always practical. Besides, I havent learned how to drive one yet (heheh).

dmp

<- 6th gear, 184mph.
