180km/h will get your license suspended and your car impounded, do you realistically need to go faster?? 180km/h on the highway is definitely french frying when you should pizza.

What does the fly-by-wire have to do with it? Any speed limiting is computer-based.

You should be glad it can't go over the designed speed or else you're putting yourself in danger with tires only rated for that speed. The limit is there for a reason.

That being said, eventually there's bound to be a company that will produce a product for you to flash your computer to modify all these limits. After investing in some better tires I don't see why it's not safe anymore (mechanically).

I recall there was a couple of months back there was a car crash dude was racing on the highway in his gf civic si, I believe he died and she was left brain dead.

Oh hope your brother doesn't mind you taking his car our and returning a cube.

Lucky you don't live in Ontario, if you get caught its an automatic suspended license, car is in pounded you also have a 10 000 fine, and I believe they have the option to cube your car if they feel like it.

This is just in ontario, that being said, its pretty easy to avoid, that being said, on an empty highway it would be fun to open the 3.5 up a little.

In Manitoba we only lose our license if we double the limit which would be 200km (124 miles). I dont think they can cube our cars? Thats messed up. Are all your highways 90km?

100km/h but 50 over is considered reckless so doing 90 in a 40 zone will result in the consequences.

If your going 90 in a 40 you deserve a ticket. Simple.

yes but here its a suspended license, ticket, car impounded and the possibility of having your car cubed. Also if they suspect you of street racing then they will automatically cube your car.

doesnt the new law here state that if you're over 50km/h that it's already considered street racing, even if you're not racing someone

Also true its kind of stupid, but yes 50 over is considered street racing.

technosquare (or how ever you spell it) took a look at the ECU and said that past 90 MPH it doesn't allow full throttle, only 80% and the faster you go, the less throttle it allows and at 142 MPH the governor is supposed to kick in and not allow you to go any faster... so after 100 MPH the car gets a little slower, after 120 MPH a stock civic could pass us with ease lol then at 142 MPH you cant go any faster.... i thought they said the partial throttle was because of the wire by throttle but i could be wrong ...

and canadian laws are crazy lol here in California i THINK (not 100% sure) that they can only crush your car if they find you racing with stolen car parts..... where i live the cops don't care too much.... me and my brother got stopped racing in his mustang and the cop just told us to drive safe lol no ticket or anything.... same thing happened to my friend when he was doing 120 MPH in a 45 MPH.....

I haven't yet found the governing point on my 3.5 but I'm sure there is one. I have hit just over 180K (113 MPH) and it was still pulling just fine.

But any governing is done by the ECU. It doesn't matter if the throttle is direct linkage, cable, or fly-by-wire. TCS is a good example of computer control - not all TCS-equipped cars are fly-by-wire.

The 3.5's get electrically limited at 146 (im guessing due to the tires) and the 2.5's at 110. Again, I bet this is most likely due to the tire ratings for each of the vehicles.

Who the hell is going 110 on the road? The track is one thing...but common guys, I don't want to log on and see another destroyed coupe or read about a horrible crash with an a/c in it in the paper...

Never said I did 110 on the road! Who read that into my words?

My concern is the limit on the track - I'll never see 146, even at a track like Mosport, but 120-125 is a possibility there (my 240Z touched 120).

Will the car even DO 146?

But I'd be very annoyed if the ECU shut me down when I'm playing nice on the track. 146 is more than enough, unless the governing eases in from a noticeably lower speed?

Yeah I agree here, I know Ferguson tracks but lets face it I am sure mom and pops pays for the tickets so they don't care how fast they rip it, its not coming out of their pockets. They don't care and when the bank of mom and dad run dry they will learn their lesson.

On a side note a good friend of mine has gotten into an accident, busted for racing and several speeding tickets (many years ago) sufficed to say he is 'uninsurable', but legally the insurance companies have to insure you, so he pays through the nose for insurance. He drives a dodge neon r/t he pays nearly triple what I pay for my insurance.

I don't want to rag on some of you younger members as some one who was lucky enough not to get caught doing 200KM/H on a public highway when I was younger, those speeds are ridiculous and not safe on public roads. Looking back I know how foolish it was, driving is a privilege not a right.

That wasn't aimed at you! I was just making a general comment for some of the posters up at the top of the thread...

From what I've read, and Hussain eluded to it, is that past a certian point, the ECU places a limit on the throttle, not allowing 100% past 110 or so. The car is certianly capable of the 146 goverening speed - however, it seems that it might take a little longer to get there becuase of the limiter...

I don't think the ECU would cause you any issues going around 120.

I've noticed that my 3.5 doesn't pull as much once it gets into the 100's as well. I always figured there was something going on, as it was too much of a difference than the pull up to 100. To 100 is decent, but then you need a decent stretch of road to get up to 120 / 130. Good to know (I guess) that it's that way on purpose. Just wish it wasn't

And please, no "you shouldn't drive that fast" replies. When I do decide to take the coupe's speedometer up there, I make sure I'm not endangering anyone else (except possibly myself, which I accept). I know this isn't a sports car, but I can't imagine not taking this car up there every once in a while! I pity you Canadian drivers..

Disclaimer: I only go that fast on closed courses, as such speeds would be illegal on public roads.

Max speed that I achieved with my coupe was around 240km/h which is about 146 mph. Got a video showing that if anyone interested to see

180km/h is something regular in my country. Most of the people who drive here are speed freaks x.x

So i see you are from the UAE, which 2 be honest with you i know little about.

So you say that 180kmh is common in your country. What are your speed limits? Do the cops mess with you at all?

Yes im interested in the video. What kinda road are you on at those speeds?

First off this is Ontario we are talking about not all of Canada, like in the US, traffic laws are usually governed by Provinces or Territories, so when I, or the other Ontarians talk about the speed laws here it applies to a small portion of Canadians.

Yes but I believe you are from Saudi Arabia or the UAE, which probably means every third car is on your road is an exotic. Considering that every rare version of the Bugatti Veyron (Per Sang etc) are usually spotted in Saudi Arabia first but I am not surprised.
