Top Speed?
 

What's the top speed you guys/gals have reached on the freeway in your H3?

Last night I did it 110 mph, it was awesome!!!!!! 35's rocks!!! :jump:


btw, everytime I'm on the freeway, I usually go 80-90 mph. :giggling:

Re: Top Speed?
 

Liar, it's governed at 94.5mph.

Re: Top Speed?
 

Ok, I'm gonna try it with my GPS next time, plus my tires are not calibrated which mean I'm going a little faster what my speedo is showing. :excited:

Re: Top Speed?
 

Ok, but you just said you did 110mph (obviously according to the speedo) when you couldn't possibly have. Why would I believe you next time? :twak:

Re: Top Speed?
 

95 MPH so far. Fully loaded (the truck not me), going down hill.

I backed off due to load, stray cows and potentail authorities radar. It may have gone to 100 MPH?

The H3 sure felt smoother than my Wrangler at 90MPH:)

Re: Top Speed?
 

I got an H3 up to about 90MPH once on a back road. It got there a lot faster than I expected actually.

Re: Top Speed?
 

Speed limiter is set at 98 MPH and resumes at 95 MPH.

Re: Top Speed?
 

76 mph with the cruise on. why are you guys in such a hurry?

Re: Top Speed?
 

Just trying to keep up with traffic.

Re: Top Speed?
 

If I remember correctly, that is correct. But going downhill you can exceed that speed:jump: Not that I would ever do something like that...(only in KY).

Re: Top Speed?
 

Because life is short! :D

Re: Top Speed?
 

It could get short in a hurry at 100 mph with off road tires on pavement.
I prefer to live long and crawl slowly over rough terrain.
But we all get our thrills differently, so to each his own.:p

Re: Top Speed?
 

Because we drive fast in Cali.............85-95 is a good cruising speed!:dancingbanana:

Re: Top Speed?
 

Sadly, I cannot tell you how many times I have hit the limiter. It sort of is freaky when it kicks in though. It is like you totally lose power until it reaches the lower speed.

We have a lot of two lane stretches where one lane is filled with big trucks and the other lane is littered with the performance cars. It can be a pain pulling out into the fast lane to pass a truck and in seconds there is a Porsche on your butt.

Before I bought the H3, I was trying to decide on the H3 or go crazy and get a 6.1L Dodge Charger. I went with the H3 because I liked it better, and I thought slower would be better too (you do crazy things at those speeds).

For those passing times, I would like the extra power. However, normally I run it in the 70-90 mph range (the norm for autobahn traffic around here).

Re: Top Speed?
 

I have had my H3 up to 80 so far, keeping up with traffic. Going down 35-E, one has to get over 70 to keep from getting run over.
What I do like is seeing some nut coming up fast on my left. Once I turn on my left turn signal he backs off. :jump: Got to love it!!

"When this baby hits 88mph, you're going to see some serious $hit."

Re: Top Speed?
 

BTW- You may want to look at the rating of top speed on your tires. I'm not sure if they are speed rated over 90mph? CAn someone verify this?

Re: Top Speed?
 

Looks like they are "Q" rated:

http://www.bridgestonetire.com/tires...r/index_bs.asp

"Q" speed rating denotes 99 mph as the maximum sustained speed.

Re: Top Speed?
 

I've never really push mine!
top speed I've reached? about 85! :D

Re: Top Speed?
 

I believe, and the chart at Bridgestone verifies this, the 285 tires do not have a speed rating. Speed ratings symbols are not required on light truck tires. Therefore, they probably fall under the R rating which is 206 mph (used for HD truck tires). This would seem logical, since GM caps the top end of all their vehicles about five miles under the tire rating (unless you have a ZO6:clapping: )
H rated tires are usually capped at around 125.

In addition a tire is good shape will not blow up if pushed past the speed rating, and a tire that is not in good shape (especially under-inflated) may blow lower than the speed rating.

Re: Top Speed?
 

43 ............. and why are people passing me on the right:confused:

Re: Top Speed?
 

Is that kph or mph? :giggling:

Re: Top Speed?
 

Last week I went 123 MPH


Down the 60 degree water slide in Orlando

Re: Top Speed?
 

Nice quote!

Re: Top Speed?
 

:giggling: What about off a cliff?
Would the limiter keep you from falling faster than 98mph?

Re: Top Speed?
 

One time trippen on the highway between a lamborgini and a LT1 Vette. I was just pulling away and the dam limiter kicked in. Those pink slips would have looked nice on my trophy rack...:D

Re: Top Speed?
 

mine was boucing off the limiter at an indicated 98

Re: Top Speed?
 

I did a little over 90 mph about a month ago in Md. I too wonder what was the top speed on the Hummer H3. Drove pretty good too at 90 mph.

Re: Top Speed?
 

Well I did honestly do 110mph in mine a couple of weeks ago, I have a reprogrammed pcm with no speed limiter...... :fdance:

I had an Avalanche riding my bumper at 90 and so I punched it, he stayed with me until about 97 when his limiter kicked in.......:giggling:

That was with the 33" duelers and not my 35" STT's and the truck was surprisingly stable at that speed. It was still climbing when I let off the gas...

Re: Top Speed?
 

Did it look something like....



:beerchug: :jump: :excited:

Re: Top Speed?
 

Why yes it did........:jump:

Re: Top Speed?
 

I think you did a typo on the R speed rating...shouldn't it be 106?

Let the rest of us know if you find the 5-star crash rating to be accurate.

Re: Top Speed?
 

Over here in Bahrain, we are limited by the "government" to 170kph... that's 110mph for everyone else, and I hit that limiter quite often ... The H3 can perform, the biggest issue is everyone thinks that 'coz its a 3.5 then it must be crap... well, believe me, it outperforms everything else.. The Range Rover with 4.4 V8, Lexus etc.. the car is GREAT.

Must admit, if they bring out a V8, it'll be adios!!!

Cheers!!!

JFF ;)

Re: Top Speed?
 

Well I hit what appeared to be 99mph, and the limiter kicked in and dropped the motor speed and subsquently the truck back down to about 96mph.

Then it roared again until 99...motor speed drop... truck speed drop...96.
I tried this three times, and then laid off the gas.

Is there a way to change the Computer setting to disable the limiter?

Re: Top Speed?
 

Nice... :perfect10s:


I have been to about 90+ but thats as fast as it would go.. Now that I know ther is a limiter. How do I get ride of it?

Re: Top Speed?
 

I've had mine up around 97 - 98 on a few occasions. Never had a limiter kick in. How do you disable the limiter?:dancingbanana:

Re: Top Speed?
 

You have to have the pcm reprogrammed......

Re: Top Speed?

Re: Top Speed?
 

I have had her at 90 mph. That was quite fast enough for me in an SUV :clapping:
