View Full Version : Speed Limiter info needed...

Long story short (and to keep within teh rules), I got "involved" with a car on the freeway that was much faster than mine, and as I was trying to catch up, I (rightfully so) got pulled over. He was a ways in front of me by this point, so he got away. The officer does his deal, I'm polite, he asks me how fast I thought I was going. Speed limit is 65, by the way. I say "around 90, I'd guess." He comes back with "I clocked you at 119". I politely told him that it must have been the other car, because there was no way I could have been going that fast in my car. He didn't believe me, and I have the ticket now. I KNOW the limiter is like 107 on SE's so when I go to court to fight this, is there any place I can get something that shows that my limiter prevents my car from going that fast, therefore I could not have possibly been clocked at this speed? I have no problem paying for a ticket of 90 in a 65, but no way will I admit to doing 120.

Seems like a logical argument to me, it would be stupid for the people to not believe you....Also, most of the time from what I've heard, the cops don't even show up for half of the court cases for speeding.

Yeah, man, you'll have to be able to prove that you didn't have the speed limiter removed, but even then it seems like it'd be pretty tough to get a regular 2.4 (or even one with a WAI and exhaust, like yours) up to 119. I'd definitely try to fight it, but it can get expensive (I've fought a few, and you might end up paying more, but you can plea bargain down, and get points reduced). If your license is at stake, go for it.

'twas a late 80's Mustang. I know the guy, I know he's done some work to it, I know it's faster than my car by a lot... I just saw him on the highway and started screwing with him.

If I could get a dealer to say that it's the stock, unmodified PCM, and then something saying that I can't go that fast... I should have it.

It'd take a SC or TC to get 120 in a 2.4 GA.

I dont think the limiter is 100% accurate imo. GT's limit at 127 and ive never gotten over 121..unles it takes like 10minutes to get 6mph when ur going that fast...

Is the GT governed or drag limited at 127? I thought that it didn't have a limiter, but I might be wrong.

107 on the SE is correct. Before I had DHP I verified that several times. My Speedometer was fairly accurate, it read 2mph high at those speeds. I could read actual speed with my Scangauge.

It's in the service manual if you get a dealer nice enough

but your big mouth screwed yourself... never actually admit to speeding, if they ask you if you knew how fast you were going, you should have just said "yes".. around here, 25 over is wreckless, I can't believe the dude wrote you for 117, what a ****

DrFabulous
02-07-2006, 08:16 PM
I know, I should have said nothing, but I figured I was already screwed, ya know? I'm going to head into the Pontiac/GMC/Saturn dealership tomorrow for a copy of the service manual... our family has bought 4 cars from them in the last 4 years, so hopefully they'll help me out. I don't even care if this ends up costing me more to fight this, I will not admit to something I didn't do.

Don't you run out of gear after going 125 anyway?.....you'd have to mod your tranny and have other supporting mods to achieve 135 and over....

Just a guess...I don't even know how fast someone has gone with their GT....

Does anyone know?

DrFabulous
02-07-2006, 08:40 PM
The limiting factor on GA's is the aerodynamics. Once you hit around 125, it takes WAAAAYYY more HP to get faster.

Haha, defintely not gear limited, at least not undergeared. Overgeared, yes. 4th gear isn't good for much acceleration, you've basically got to the top of third, and then you're out of steam unless you're built way past stock power levels. My SE, with a 3.08 final drive will do over 140 in third. It won't climb in 4th, too steep, but with enough hp it would top forth at like 220 or so. A GT has a 3.29 final drive ratio, they shift at something like 136... I'm not exactly sure, but it the same thing, not enough power to climb in 4th. Bad for the tranny too, heats the torque converter a LOT in 4th gear w/o lockup with full power being fed to it.

GTs go higher than that. I've been to 115, the car was shaking like Muhammad Ali, but it got there.

Matt if your car is capable of those speeds then the trade is back on! lol

Back to your ordeal. I got pulled over for 71 in a 40 over the summer. So I decided to fight it, even though i was actually doing 71, and I just went in with the "feel real bad" attitude, saying how i know if someone would have pulled out that i would have hit them or if a kid would have ran out i would have never stopped in time and probably killed them. The cop (since i knew him) helped me out by saying that he thought i learned my lesson and what not. So she [the judge] dropped it to 50 in a 40. So just go in there and be sad, and also defintly get some records showing that your car doesnt go 119 (or whatever he wrote). If anything go in there, show that you cant go that fast, then say that you would plea guilty to 80mph.

im not sure what everyone is saying about the speed limiter on the GT is... but i have a stock 2001 GT and i've had it up to 125 (on a flat road) before with 3 other ppl in the car on more than one occassion. Without that extra 500 lbs of passenger who knows... I live in East TN and all it is here is long highways, interstates, and backroads. I raced my friends Oldsmobile and i have had my GT pushin around 135 on a downward slope so i disagree with all the rumors of the GT speed limiter

GrandAmGT1996

Around 135 is all you will get out of it, they are governed. Just like my '96, except it cuts me off at 106mph.

Yea, not rumor, defintely fact. Stock speedo's are known to get in-accurate at those speeds. Reading up to 5mph high isn't uncommon.

Uh no, if he can't possibly have been going that fast, then the cop doesn't know how to use the radar gun, and he should get off completely... simple argument

Anyways

Governor has been covered on here a million times, it's a fact what they are governed at... Your speedo might not be showing it exactly, but the speeds for SE's and GT's have been listed in this thread.. case closed. no more discussion on governors or how fast you think your car got up to on a flat road with ideal conditions :erika:

IIRC, the highest possible speed is determined by the speed rating of the tires your car originally came with. Since it is an SE it probably came with S rated tires which are rated for 112. GT's come with tires rated at 149 although the car probably will never reach that speed.

That probably won't help you since you would have to prove that you never modifed the pcm.

In NYS getting convicted of going over 40mph or participating in a "speed contest" will get your license suspended automatically.

Never admit that you were speeding. You have the right to remain silent!!!!

I dont think he will have to prove anything about having a stock PCM. All he has to do is prove that the car is governed BY GM to not exceed a certain speed. That should be fairly easy.

I cant believe that they would take your liscnence for contesting a speeding ticket. I just cant believe that.

What SE's and GT's are limited to has already been said in this thread. You are right that they are limited by tires, but off on your #'s.

I don't care what right I had, I screwed up by speeding, and I was honest about it. If I had said nothing, would it have made a difference? No, cause the ticket is for 119.

Yes but if you can prove that your car cant do that speed you will most likely be let off totaly. But yeah you broke the law, but if you can beat the system then do it.

If the ticket is for 119 and you can only possibly acheive 107mph, its bogus, he obviously got the wrong cars speed. So, it wasn't your speed, so the officer doesn't actually have an idea of how fast you were going. There is your defense. Like everybody else said, admit nothing, thats the whole idea behind "Anything you say can and WILL be used against you in a court of law."

If you tell the judge that the car can't do 119 because its limited to 107 from the factory, he can ask you if it has been altered in any way. He can also ask the officer if the car looked stock. If the officer noticed a fancy aftermarket exhaust or custom gauges on the dash that defense might not work.

I got pulled over last year and the dumb bitch said I was going like 70 or something like that in a 45 and in all actuality I was going 60. Needless to say I said "you're wrong cause I had my cruise set to 60." She gave me a warning, but regardless I was furious. I will admit when I do wrong, but if you're going to blatantly lie about me doing something I wasn't, then we've got a problem. Oh and she made up some other crap about how I blew through a yellow light honking my horn as if to let people know that I wasn't stopping... Yeah...

Yup, just like the reason why I couldn't take my '93 Saturn past 80mph -- it shook really bad (and barely had enough HP to make it up to that speed in the first place). My GA, on the other hand, is perfectly stable up until around 110mph.

This whole thread is a very interesting read. Unfortunately when it comes to traffic court the burden of proof is on the accused rather than the officer. Though its certainly possible to get off with the right proof. I knew this guy who had a 03 Grand Prix who got pulled over for "reckless driving" because his trans was slipping and dropping into gear suddenly causing the tires to chirp. He got a statement from the dealer saying as much and got off so it'll be interesting to see how this turns out.
