About how solid are these numbers? I already know the HP numbers are bhp, not whp. I'm talking top speed and quarter mile?

Also, what are some things that are known to be wrong w/ 2004 model RX-8's? I hear people say they have "kinks".

Top speed of the RX-8 is around 150 mph for M/T. A/T is governed to 125 mph.

Quarter mile is mid-to-high 14's.

Some ppl got up to 180+ mph, but thats on a dyno. So I dont think our 8 is speed limited to 150

but I dont think we can even hit 150mph, due to all kinds of other restictions (gravity, wind, etc)

Huskyfan23

Oh, I know it's not speed limited to 150, but that's as high as I think the 8 will allow due to RPM limitations (as well as the reasoning you mentioned before).

I certainly don't know from personal experience.... I've never tried anything above 110 in the 8.

Yah. Doing 150 would be ill concieved, considering your probably hitting redline w/ the stock setup and tune. I looked at vids on streetfire and didn't come up w/ much, besides RX-8's getting owned. And one guy hitting 130 mph.... so i was just wondering.

As far as problems w/ RX-8's? What are they? I have found that almost any Mazda car has some kind of "kink" that can drive them crazy.

Like for example the 03.5 Mazdaspeed Protege: 1) their swaybars clunk so people remove them or fabricate brackets w/ newer adj. endlinks 2)their plastic turbo pipes goin to crap and leave people stranded 3)plastic vaccuum hoses need to be replaced w/ silicon 4) along w/ a good ground kit

Same thing happened to all auto companies.

Mazda is not alone.

Don't kill anyone.

good job

There's no drag on the dyno, that helps

RX-8Newb

yeah, it is not limited by a computer to 150, just aerodynamically limited.

NoTears316

Top speed I have seen on a dyno is 184

Rx-A-Ho

The gearing on the 8 will allow a top speed of ~180 mph. But on the road with drag and horsepower the top speed is ~150 mph. I have a friend that hit 147 mph in his 8 on the road.

to bad you are not on the autobahn, then you could really get on it for a few miles and not have to worry about anything

CarAndDriver

Ticket.....

bigal_miles

Ive to got 140mph then crapped myself so slowed down still had alot of poke left though just got to scared !!!!

RX-8Newb

I have been 170 mph drafting behind a friend of mine on an R1 ( on my bike ) And 150 mph in the wrx

636

Top speed runs on the bike is fun. Lucky im still alive i usually went 165 mph with my zx6.

funspork

150 on my CBR1000, and hit a raccoon and died,,,,,,,,,, well that was why I sold it after I did it, and looked at my new born baby.



150 in my RX7 in 1988.

I think 150 is perfectly reachable in a stock car. I've hit 143-144 in mine twice. I dont belive you would get much farther than 148-152 but i do think you can hit 150 with enough road. after 120ish it start to get sluggish, after 130-135 it comes to a crawl. but i still had just a little left at 143

your thread fails. 146 gps.

I'm no expert, but I hit 150 in my 98 Volvo S70 T5- 5 speed. It was 236 HP and a .32 drag coefficient. The RX8 has similar HP and a .31 drag coefficient. The Volvo's top end was 155. Same in my S80 T6. (both times on a 4 mile banked oval track mind you) So, I would assume the RX8 should be around the same 150-155 drag limited top end.
