I would be seriously disappointed with this car if it couldn't even reach 140MPH. Seems like later RX-8s have better top end performance.
I got my old 1994 Acura Integra with 170HP and 8200RPM redline up to 130MPH at least once so it'd be pretty sad if an RX-8 couldnt top that.
I do hope that anyone who attempts to find the top speed of their RX-8 does it in as safe a manner as possible mainly not hitting anyone or anything else in the process.

From what I've learned about the Subaru STI, it would do 155 stock, and if you installed an ECU chip, would remove the limiter allowing for a top speed of around 170.
Now I found this same type of chip for the RX-8's and would assume it would remove the limiter.

Anyone here have this?

First off, the car has no speed limiter. I have had it to 185 when the car was on the dyno.
I've done 154 mph in 6th on a long flat road.
As mentioned above, 6th is really too high for top end and 5th is too low. A gear in between the two would provide best top end power.

On my trip back from picking my RX8 up in dallas, tx I was upto 110 in 4th gear and it was around 8500 I think. This was in passing someone and I soon slowed down as I don't need a ticket thanks

I find 144 to be pretty fast. Some years ago I had my 390 HP vette up to 145 at CMS on a track day. 6500 RPM. The big blocks break valve springs much above that so I held back. Besides the front end gets so light in the vette it's downright dangerous above 120 anyway.
