Speed Govenor

I read a while back that Mazda put the limiter do to the tires. The start to shred after 155...though I don't know how long it would take.

Our stock tires are Y rated. Y rated tires are tested to endure up to 186 mph (300 km/h)

So I doubt they will shred at 155 mph

also the engineers that create these tires over engineer the s*** out of them, im going to share a moment of stupidity with you, the time i hit 135: i hit it with my snow tires on, which are rated for 99. (doh)
 
Tires shredding? Dont beleive everything you have read. These tires on also on some Porsches capable of speeds much higher than 155
 
yeah Y tires are rated to around 180 MPH. After that, you gotta buy Z rated tires. Thats why those fancy super cars that can go 200 MPH come w/ Z rated tires...

and it's not shredding, it's the rubber cant stand the centripical force over a certain speed.
 
Automobile Mag said they got a stock car to 163 in Germany.

I've been 135 in the MS3 on track and it was very smooth and still pulling reasonably well. Longer straight and I have no doubt it will run as fast as Automobile said. If I remember the article correctly, I think they ran out of road before they ran out of acceleration.

PS - I can't believe you guys trust public roads enough to push much past 100mph. As bad as our interstates are with road debris and other random fluids, critter parts, trash, etc. I know our local interstates are worse than average, but trucks are always dumping sand, rocks, cinder blocks - you name it.
 
i knew the conditions of the section of i90 i was on, because i was driving it very consistantly, and believe me i didnt stay that fast for too long ;-) but he handled it like a champ
 
Cars now can handle highway conditions you are naming at 100 with no problem. Cars are built a hell of a lot better than we think.
 
According to Motor Trend and Automobile magazine, the 155 is not actually enforced. Both report getting a US version of the MS3 over 155. (162 to be exact.)

That said, has anyone actually hit the 155 mark and noticed the electronic limiting? I have been in my car with a cop driving it at 148 and we could have gone faster, but like so many have posted, why in the name of sunny Jesus would you need to go faster than 155? (Or even 120+?)

lol, how in the world did you get into the situation of having a cop drive your car at 148 with you in it!?
 
He is an old buddy of mine. He actually is one of the top drivers for the DC police. He has taken several professional driving courses including specialized combat driving classes. I figured if anyone could drive a car in a straight line, he could. Plus, if we got pulled over... it is all on him.
 
Like I said we had more left, but we were running out of clean, straight space and I didn't want to go any faster. The car felt pretty smooth though. I was never frightened.
 
They just feel crazy light to the driver at those speeds. Definately doable though. There are a couple stretches by me (10 - 15 miles worth) of straight new cement that at 4 or 5 in the morning you can open it up on. At that speed if you see lights turn on, keep going, they will never catch up!
 
Off topic but I had an old 92 Nissan Maxima SE. Loved that car but the tranny protested after 200k miles. It had a 3.0 V6, had it up to 143 and it was so smooth but that's simply all the motor had. That was a great interstate car.
 
I wonder why the drivers at car mags did not? I have the issue of Automobile where they published the 162 findings.

And why not? You aren't serious are you? You don't have to answer this, but on a weekly or monthly basis, how often do you drive over 120 when you aren't on a track?

Carter banned the creation of the neutron bomb in the 70s. Sure we could build it, but isn't a 155 Megaton bomb enough? Why would you need a 165 one?

LMAO, great point. Defeats the purpose of ever buying a higher performance car than the one you drive regardless of income then though.

I live 10 minutes south of Columbia.... we need to go drive together!!

I was racing around with an IS 350 (and winning(glare)) and when I finally looked down I was at 145. Seriously scary though. I can drive all day at 85, but I almost never pull up past 100 unless I have a good reason.

But on topic, you gotta be crazy as s*** to need your limiter removed.
