Increasing max speed/removing the governor
Just curious if anyone has tried this or knows how to do it.....
This past weekend I wanted to find the top speed of my 8. So on a 20 mile straight away (yes, more than enough road than I needed) I figured I'd find out. I reached 131 mph in 5th gear ranging in the high 7000s of the rpm range. However, once I hit that speed, the governor kicked in and wouldn't let me go higher. I was a little P.O.'ed since I still had 6th gear to go through.
Does anyone know if there is a way to remove the governor and replace it with a different chip? Or is there possibly a way to change the settings so it is set to cut out at a higher speed or even not to cut out at all?
I am a rookie at all this, so please try and explain to me in simple form.
Thanks for all your help in this.

I can't recall exactly but didn't someone mention it was limited in 5th gear (mechanically or govenor) but not in 6th? Really, how fast do you need to go anyway...

I recall that the US version is "drag-limited", meaning the only limitation is engine power vs. aerodynamic drag. Will depend on how much power you're making, altitude, humidity, how clean the car is, body modifications, etc. You won't reach top speed in 6th gear.

Thank you for everyone's suggestions. If you are wondering why I'm wanting to drive this fast, it is only because I want to find the limits of this superior machine. On the vacuum idea, you think Eureka or Dirt Devil my want to work with me on this? I'm sure it would be great PR.
Thanks again to all, and happy new year!

Here's the real facts:
- In 5th gear, there is NO governor - you should be able to hit the rev limiter in 5th, which is around 148 mph.
- In 6th gear, there IS a limit at 148 mph. This isn't some random number - Mazda chose 240 km/h as the limiter speed, which happens to equate to ~148 mph.
- It's German car manufacturers VW, BMW, Mercedes, and Audi who have a voluntary agreement to limit top speeds to 155 mph (actually, 250 km/h). Porsche has never been part of that agreement. Mazda has nothing to do with it, and as mentioned uses a 240 km/h limit.
Baseballgenius80, there may have been some other factor kicking in to limit your top speed (slope of road, headwind, safe mode in engine if running too hot, etc), but it wasn't the rev limiter.
Regards,
Gordon

Thanks Gordon,
That's pretty much exactly what I was looking for. Thanks for all the information. At the time when I reached my top speed (so I thought) it felt as if a governor was kicking in. Like I said, I'm a rookie at this, so it helps that you cleared that up for me.
Thanks again!
