Sorry guys, different culture.
I'm French. Almost no car in Europe has this type of governor and I've always been able to try at least once with each car I had what the top speed was.
And you'd be surprised what kind of speed you can reach even with a 1.2L engine!!!
With the type of car below, 60 hp, and ok, I admit it, a nice long down going road, you actually can reach about 127.
All the good aerodynamics lessons cannot explain that.
But I know there is some truth in what you said, engifineer, I'm not saying you are wrong.
However with my TRD suspension, and a lower center of gravity, I'm confident it would drive at 127 very safe.
But not on most highways, at least here in MA: too many cops and too many road hazards/holes/bumps ...
On a European highway, it'd be safe and my aerodynamics would do great.
But thanks to buderic, I also have my answer. Change the ECU is the way. I'll see what my top speed is on a track, there is most probably not so many tracks where I will even have enough length to reach that speed anyway.
Thank you guys.
