Back to the dealer
Guys
have any of you been back to the dealer and politely (!) asked WHERE'S MY GODDAM TOP SPEED ?
If it was me and I'd had that experience I'd be knocking down the dealers door, on the phone to Mazda, exposing this in the media etc etc.
This is WAY down on what Mazda claim - and if this is it, they are ripping you off big time - this has got to be illegal surely ??

Illegal
Not on a track, not in some countries in Europe...
But that doesn't change the fact that if it's meant to do 150mph (or whatever it is) it should do it ...
If it doesn't then you've been ripped off, period.

not very long at all, and it was a SLIGHT incline too, but dsc was completely off, AC running on 2, and it seemed there was more room to go also
if the top speed is 148, with electronic limitation, it will DEFINATLY get there

A recent Road & Track article states that the RX8 has a top speed of 148 mph, and that the top speed is Electronically limited.
PS I have had my 1990 Miata up to 120 mph. My car has the 1.6 L engine.

Can some one jack up their car and take the wheels off and then lower the suspension onto a floor jack [ on each side of the car ] so the CV joints are at their normal angles, and then procede to see what the maximum speed achieved in 5th and 6th gear.
Assuming the Rx-8 isn't like the M3, where the engine speed is capped to 6000rpm when the front wheels aren't spinning.

...why not just do the math?? in 6th at 9300 rpm the speed would be 186mph spot on (~300kph).

(edit: sorry, that was a nerd joke about the split between theory and application. I didn't mean anything by it

...i'm not saying the car would ever touch redline in six without major major work, i'm just saying you can work out whatever speed you want in whatever gear rather easily, with a pen and paper in minutes.

Governed @ 148
It's funny how people put in their mind that if something is listed as being governed/ electronically limited to 148 that they assume that it's capable of doing that....they might as well have said "electronically limited to 250 mph"?....maybe if we dropped it from an airplane.........

On a deserted highway, 3,600' altitude, 242kmh ( about 150mph) according to the speedo, not a GPS.
I did not detect anything stopping/limiting it, but I doubt I could get it to go much faster.

I thought it was limited too, but then bear in mind speedo, not GPS, so probably a few kmh off reality.
BTW, I was a bit nervous. This car NEEDS a chin spoiler if one would do that much.

The 3rd gen RX-7s were ECU limited to 155 MPH. But if you left off the gas a little then back on, you could get pretty close to 160. Don't ask me how I know this 
I'm sure the speedo could be a bit off at that speed too.

Why didn;t you shift to 6th??
I pulled 244 on Highway 40 at about 23C.
6th gear.
Took a run down the hillinto a valley, leveled off at 225, shifted to 6th, pulled up to 244 before I hit the climb on the other end of the valley.
Came over the top of the hill at 215.
That is when i discovered just how good the brakes are.

3rd gen RX-7s were definitely NOT speed limited, at least not to anything below 180.
I have in-car camera footage of 165 down the back straight at Sebring (full lap after passing NSX).
I have personally buried the 180mph speedo and have seen radar measured 204 from a similarly modified RX-7. Do not do this without a vented hood. Otherwise there will be little to no steering over 150.
And yes, those are MPH numbers.
