How fast is a RX8?

[e240]

Buddy, you need to calm down and re-read the point of my post, coupled with the post by Ben. My post was never about a comparison rather it was a clarification on the Technology.

As for how well I did in mine, I'll leave it to you to do a simple search and find out. There's no secret there.

As for what i run in my car, I basically have a street car, hence I run with the VTEC mechanism. However, as to my point, if I were running a Track car, I would definately seriously consider running just high profile cams as revs hardly ever fall below 7000rpm (unless a mistake is made) - There are many advantages to doing this.

In regards to this thread, its just people comparing and exchanging knowledge. Even if its pointless (and they need to take it down to the track), its not harming anyone. You need to chill and maybe join in constructively.

Finally, if you still want to run me, I'll oblige at any of the three tracks around. There's a circuit club day at wakefield coming up in December.

Why not you take your Vtec (or with your killer cams) and drag mine?
My point is that...why is there so much comparison? just do it and stop assuming...I think all of us would wanna know the results...

One thing, you seem very experience in VTEC...I really wonder how well you did in yours, or you just read from the book...but if you did very well, like there is some hidden secret to make your's somemore special than others, please do show me some trick up your sleeves...Cause i'm very curious bout it as well...

^^ Agree.

However, when I track, for me the most used RPM range (during cornering) is between 5k-7k+ (depending on how narrow the corner is). Do you also always keep your RPM above 7K when cornering?

Well, at least above 6000rpm for my car and setup.

I try and keep the engine as much as possible in the powerband, and it really depends from engine to engine, and driver to driver.

Anyway, I think we've strayed way off topic so that try and bring this back to "How fast is an RX8".. :-p

What does a standard RX8 do over the 400m run?

I raced one with a friends B16 EG Hatch and beat one (He was clearly trying too)
But then I just watched a Topgear episode where around their track it was as quick as a M3

You pretty much answer your own question dude, u asked how fast it does on a straight line, and how the B16 can beat it .. or indicate it has close performance figures.... then you compare its performance around a TRACK which consist of corners and NOT JUST STRAIHT LINE against a M3 and indicate it as fast as a M3 on a track ... what does that mean to ?

I think that clearly tells me its not so fast on a straight line but the car's overall cornering and balance can matach a M3 time around track ?

those that just worry about straight line speed.. dont buy a rx8.... get a rocket...

RX8 is not that whole lot faster than a B16. Definitely faster on paper but every1 claims the 0-100km to be faster than it is actually tested. Ha.

2 ways B16 stands a chance is:

1.) Good I/H/E, HD Clutch,flywheel,JUN/TODA racing cams,valve spring etc, Power FC+gd tune.. B16a in an EG/EF maybe a Stripped EK will keep up with a RX8 that is pretty stock. Might on might not win depend on how noob the RX8driver is.

2.) B16a with I/H/E, HD clutch and flywheel, NO ECU.
Might only keep up with an AUTOMATIC RX8.

Dont underestimate a B16. No torque but there's sure gd top end ready to put up a gd fight.

So it takes a pretty extensively modded EG b16a just to keep up with a stock RX-8. Ok... so that means Stock RX-8 > Stock EG B16a (AUDM, if you consider engine swapping as stock).

2.) B16a with I/H/E, HD clutch and flywheel, NO ECU.
Might only keep up with an AUTOMATIC RX8.

Pretty sad considering a fully bolt-on equipped B16a just keeps up with an auto RX-8 which is already slower than an Euro, which is a slow car.

your dreaming mate!!!! u have a ek which is heavier so that mite be your expriences
a rx8 does around 6.6 sec 0-100 AUTO 7.5 sec
eg b16a does around 7 sec 0-100
ALL STOCK

so he has a eg 1050 kg car with 125kw
rx8 1600 kg with 177kw

go figure mate

i have a eg with a b16 and some of those mods u mention and lets just say easy !!! ......... FOR ONCE AND FOR ALL

dude... rx8 weighs 1340kg. its a rotary, not a shitty8. rx8 auto is slower because it makes less power, so the 0-100 time is slightly worse.
plus, the main difference in acceleration can be attributed to gear ratios. rx8 gear ratios are designed for efficiency in mind and low rev cruising (altho rotary and efficiency dont mix), ie. first gear redlines 70-80, second gear 110-ish, third at 150-160-ish. compare that with a civic, first redlines around 50-60, second around 85-100, third around 130-ish. shorter ratio = faster acceleration due to retaining more power on upshifts. if you want to compare them more directly, have the rx8 launch in first and the civic in second, then the comparisons would be slightly more relevant.

rotary motors are also more efficient in that more of their power gets to the wheels. a stock b16a jdm spec might produce 125kw at the motor, but it produces like 80fwkw (correct me if im wrong), where as the rotary puts around 110-130rwkw (correct me if im wrong again). these are going by the dyno results people seem to put online. factor in weight and the power to weight of the rotary is still slightly better.

in the end, the answer to the question of this topic depends on the definition of fast. are we comparing straight line or track time? stock or tuned? feeling or records on paper?

[90LAN]

oh well carrying less weight and still goes slower than a eg with i/h/e
but the thread is about a EG WITH A B16 BEATING A RX8!!!!
doesnt matter what else bullshit u come up with
thats the fact ........
TAKE IT FROM SOME ONE THAT KNOWS
ps mate i was replying to VTIR that his claims were not correct
thats all if u read that part

im not making up bullshit. you're trying to compare a stock rx8 with a tuned civic. thats like comparing a stocko ferrari with a 1000hp gtr, its a stupid comparison.

mate read what the thread is about ....
stop being in denial
55k + car compared to a 12k car i think that is a good comparsion

have u got a eg with a b16 ????

any thing esle u can come up with mate .........

by the way a stock enzo ferarri would give a 1000 hp gtr a good run for its money ......

Not really. 1st gear in the RX-8 is still shorter than the 2nd gear of the Civic.

rotary motors are also more efficient in that more of their power gets to the wheels. a stock b16a jdm spec might produce 125kw at the motor, but it produces like 80fwkw (correct me if im wrong), where as the rotary puts around 110-130rwkw (correct me if im wrong again). these are going by the dyno results people seem to put online. factor in weight and the power to weight of the rotary is still slightly better.

Power to the wheels is a function of the transmission and drivetrain. Not the engine.
B16a puts down more power than 80kW atw. And I've seen stock RX-8s put down anything from 109kW to 122kW (both on the same day and on the same dyno)
