whats RX8 top speed in 6th gear?

i thought my manual says that the car only goes up to 134 mph. how did this guy get his 8 to go to 184 mph before fuel cut off? is this fake video or something?

What page does it say 134mph?

sixth gear is limited anyways. You can get up to 184mph by redlining it in 5th

Mine is a prototype, an it hit 206.9 mph. Then again its a prototype, so no big deal. Stock can get pretty high by "stock" standards. I raced a mustang stock an it wasn't as fast as I thought it would be.

Still, i love my RX-8, speeds differ, witch is no big deal.

Peace yall,

Car is drag limited to 150-55 on the flat and level at 0 elevation. Like on the z06 top speed will be easier to attain in 5th cause you will have more usable torque (at the wheels) in that gear. Cant do this in 4th cause it redlines at 130. No limiter cause we have tires that are rated above our drag limit. the TSR to 180 was real but on a dyno with (obviously) no drag. (on the same topic, there is a vid of a guy on a standard bicycle behind a drag racer, both doing 150. Normally, guys on standard bikes are draglimited to 40 on the flat.)

i believe the AT are electronically limited to either 125 or 135 (can't remember which), but the MT are not limited...the top speed is drag limited, meaning the car doesn't produce enough power to exceed that speed, which ends up being ~155, as mentioned above.

as geared, here are the theortical speeds in 6th...
176mph @ 8500rpm
181mph @ 8750rpm
186mph @ 9000rpm
191mph @ 9250rpm
196mph @ 9500rpm (fuel cutoff)

Untrue - 5th gear tops out, redline, about 155mph.

6th gear is 'not' limted - at least not electronically. On the streets? this car would be lucky to see 140-145mph I'd guess.

Other guys w/ rx8's saw 185mph...before fuel cut. "this guy" (me) just floored the damn car, and that's how fast the dyno got to.

A member in Germany with a US spec car reached 155 mph on the autobaun. This was in a post about a year ago.

I wonder if its possible to reduce drag by putting something on the front bumper to redirect some of that air. Something small of course, don't wanna rice out the 8.

You could always do like NASCAR and tape some of the front up with 200mph duct tape . BTW my car has seen 140mph and only took it about a mile to get there if I recall.

Yeah. Stick a Turbonator right on the hood above the "winged M". That will smooth out airflow, provide a "ram-air" effect for the intake, put chocolate on your pillow at night, and increase top-speed to the "as-advertized' 184 mph.

Hm, out of curiosity....

Anybody knows what the top speed of a chasing police cruiser is?

Living here for fife years now, but still missing the Autobahn... In particular
since I have my RX-8....

police cruisers

crown vic: 0-60 in 8.7 top end 129.
impala: 0-60 in 9.2 top end 124
intrepid: 0-60 in 8.7 top end 135
camaro: 0-60 in 5.7 top end 159

but remember, they are likely better drivers than you, there are more of them than you, you can't out run radio, and there always the helicopter. so don't go getting any bright idea. and by bright idea, i mean extremely stupid. :p :D

So are those with or without light bars? Some of the light bars, even the low profile ones make a huge ammount of drag, esp. at speed

the article that i got those from didn't say. but from what i understand, its more of a weight issue than aerodynamic. most of the cruisers top 4000lbs, and don't get much of an engine upgrade to compensate.

well the only way weight cant affect a cars top speed would be if the weight lowered the car, or made one end (trunk for example) lower/higher than another end, that would end up affecting the aero dynamics.

So for all practical talk, weight doenst matter in top speed, only how long it takes to get to top speed (accel.)

You are right all police cars are heavy, the standard outfit or radios, lights, equiptment is 500lbs, most of those cars are already around 3500 so with an officer and fully toped off, over 4000k isnt suprising. Thats what makes it even more amazing when you see a crown vic rocket away from a light, or fly around the corner, that bitch is 2 tons!!!

Anyway, the only thing that affects top speed of anything, is power, gearing and drag.

Of those cars you listed the camaro is obviously the 'slickest' shape, so it would have the least drag. also has the most power, and probably the least equiptment inside, since its just a chase car most of the time.

I have heard figures that those light bars, the big ones, slow the top speed of a cruiser down by about 20-30 mph, and the smaller ones are closer to 15-20mph slower. It adds a lot of drag. So does the spot light and push bars at the front.

Now I know first had that a crown vic, at least the ones the dallas PD had, can go at least 122mph. So with the figure i mentioned, its top speed should be around 137-142mph, since it had the low profile light bar.

also as long as were talking about aerodynamics, you see the 'coeficent of drag' mentioned a lot with sports car, one thing to note is that most companys test the car WITHOUT side mirrors as they MAJORLY disrupt air flow.

I believe Mazda states the 6 speed manual tranny model is electronically (governor) limited to 148 MPH. I've seen this figure published in several popular car magazine reviews also. Car and Driver states slightly less in their long-term test of the RX-8. Also, I think whatever the top speed happens to be, it is reached in 5th gear.

Top........

Top speed last year (on a runway), was 146mph, this year I repeated the test, could only get 142mph, only difference was 89 octane fuel this year..... :o last year had 93 octane.

Unless you have some major mods (F.I.) you will use fifth as your top gear, sixth just loses speed back to the 130's.

The autobahn certainly helps to find out about top speed.

So far I reached 157 in sixth and 156 in fifth. It takes some patience though, there's not much acceleration above 145 mph. Often the car tops out around 150 in sixth, probably depending on enviromental factors such as wind and temperature.

What kind of cruising gas mileage do you get at that speed? LOL
