could a 304 hp gtp realy go that fast riding its limiter

MPH is ment on the topic cant edit that sorry

I seriously doubt it. If you watch the video he has posted the IP cluster is a metric model like used up in Canada. It is reading kph on the outer scale not mph. In order to read above the mechanical limits of the analog speedometer he would need a HUD which has a digital readout that can be switched between metric and English.

BTW - Your post title has been edited to read mph.

Yeah, I agree w/ him^^^^. Theres no way he hit 190mph, he was going by kmph which 190kmph is realy like 120mph. I hit 167mph in my GTP and i didnt have to many rpms left to go before I redlined..at least thats what the Heads-up-display said anyway, and im pushing about 260whp and 330fpt w/ a stock tranny....I know zzp has a turbo grand prix thats close to 200mph but it has a rebuilt racing trans and block and pushing a lot more than 304 HP, its also the fastest fwd 3.8L and runs the 1/4 in 9.01 @ 150mph. Does anyone know how to tell theoritically how fast a GTP will go condiering it has stock tranny and gearing? I know There is a mathematical way to figure it out but im to lazy......:grinno:

It is a simple ratio problem. For example, if at 3000 rpm you do 70 mph, at 6000 rpm you can do 140 assuming you have enough horseporwer and no slippage.

yeah theres more to it than that though...it depends on what gear you are in also....there's a more complicated way that you factor in the gearing the car has, horsepower, redline, ext....

If at 3000 rpm you do 70 mph in high gear, at 6000 rpm you can do 140 assuming you have enough horsepower and no slippage.

I assumed that the redline in the example was 6000 and that the car was capable of reaching the redline with whatever axle ratio was installed ("enough horsepower).

I also assumed standard tires, not racing slicks. There is no appreciable increase in tire size as speed increases as is the case with a drag race slicks.

The funny things is when you watch that burn out, he has the e break on the whole time. That tells me the car cant burn out that far with out it being on.

I watched that video and his car was doing 110 mph. I had a 2005 Saturn Ion Red Line Supercharged 2.0L I4 205 hp. I sure do miss that car but it was a real headache and had nothing but problems, saturn later bought it back from me after I had put 12k miles on it.

Also, is that his Check Engine Light on the whole time he is accelerating? That's got to be good for the car....

100 bucks says the reason his check engine light is on is b/c he has a reprogrammed pcm and he needs a caselearn....wont hurt the engine in anyway...

I don't belive that. It's probably a misfire because the engine is running at such a rich mixture at that high of a speed, my GA SC/T does the same thing around 125 mph. I also had a supercharged Saturn Ion Red Line that did the same thing.

Every 98-03 grand prix will through a SES light when you put in a reprogrammed computer unless you used a powertuner and tuned it yourself.
I had a caselearn done on my car after i put in a zzp pcm and the SES went off....and ive never had the check engine light come on at high speeds on my GTP...go to streetfire.net and watch all the GTP videos that show 0-60 or 0-150mph runs with the camera on the gauge cluster and 95% of them will have the SES light on the whole time b/c of this reason of not having a caselearn...and you owned i Grand am and Satarn hey are both GM but not the same exact cars or have the same pcm programs as a GTP so its going to be different.

Well just to prove a point I've watched 10 different videos. Very time consuming I must say to find some that are decent in length and show what I want to see. But non of these video's show a check engine light flashing. Now what is the point in getting the pcm flashed? Raising the top speed cut out? More hp/torque?? You state the ses light being on. What I am talking about is the SES light flashing. A flashing light is a misfire. A steady light is obvisouly what the car sees as a malfunction in the emmissions. So i think we might be talking about two differnt items here. lol I just wanted to make sure we're on the same page. By the way, I noticed that the speedos only go to what, 120 on the GTP? Must have to use the HUD to see your actually speed then huh?

Also the temp guage is reading stone cold and the tach actualy shows a drop in rpm to 4000 as he accelerates past 175. 190kph=118.06mph. I had my tired old 96 SE 3.1 over 105mph this fall while going thru Montana.

If the check engine light is flashing then yes it is probably something else...but if it was just on then it usually is b/c they had the pcm replaced...And yes i have a Heads-up-display on my car and it will go past 120mph on the HUD but the spedometer only will read up to 120..so if you dont have a HUD you dont really know how fast your going after 120mph...

I think thats stupid! I miss my Red Line, that sure was a fast car. Saturn said they were 205 hp at the wheels but they were actually 235 hp when tested on a dyno. That's 125 hp per cubic inch of displacement. With stage 1 and two up grades you get more hp and a higher redline allowing the car to reach nearly 170 mph but you also pushing almost 7 grand on the tack.

Those cars will get a GTP a run for their money when they're not breaking down. Mine sure was a peice of shit. Here are a few pics of it.

Thanks for looking at my page everyone. And yes...I most certainly was going 190kph in that video, down the 401 here in Oshawa. I was actually doing 196kph, or so the HUD read. I could have gone faster...as you can hear from the engine...but, things get hectic on a Trans-Canada Highway, in the middle of the day. Also, my shift points are at 6200rpm. 6300rpm? Hmm, can't remember.
Of course, if you had actually paid attention...you'd of noticed it was in Km/h....but that's okay, I'll turn a blind eye at your lack of attention to detail.
Don't forget...we use Metric Gauge clusters up here in Canada. You know..Metric...the system that makes sense? The system that the rest of the world uses? It's amazing how many of you Americans forget that point. And I'll say it again, "No, I'm sorry, I can't tell you where I bought a gauge that goes to 190MPH....because I don't have one"

The SES light was going off because of a dirty contact on my MSD coils. "Misfire #3" ...turns out they're garbage. Also, I had a stock DP on at the time, and there was an exhaust leak between the DP, and the Exhaust Manifolds. So...will that $100 be in US Dollars? I accept Paypal, Money Order, and Certified Cheques, haha.
The DP, and EMs, have been replaced with a W-Body Store P&PEMs, and a Hogan DP45 3" DP.
There was Definitely a CaseLearn after the new Delco DHP1.0 PCM, VIP Motorsports, the company that modded up the car before I bought it....did that.

And yes, sorry to say.....at the point when that video was taken, the car didn't have enough torque to do decent burnouts without the Parking Brake on. ...not that it does a whole lot of good, because the car DRAGGED itself.
But that was a long time ago. I'm sure it would do a decent one now, but I'll wait for my Rockers, Intercooler, and 3.0" pulley before I post another.

Oh, and to Mr. American Eagle, with the Saturn.... Nice car! Though, I think a smaller engine like that...2.3L is it? Would benefit more from a Turbo. Even then....it's not really any match for a now near 270whp GTP.

Thanks for the interest guys!

Well after converting its 118mph. I do speak french and i have lived over in france for a little bit, and half og the cars are in mph and some in km/h. I can convert. It was a good video. Do you have to learn french up there in the schools over there? I went up there a few years ago, and they only understood half of what i was saying, and found out they speak more or less hillbilly french, not the real french that everybody else uses!
vous voir plus tard! PAIX!

Andrew

Yeah, the french spoken up here isn't the same as french spoken in France. And yes, from grade 4, until grade 9, a french course every year is mandatory. With certain exceptions.

we use Metric Gauge clusters up here in Canada. You know..Metric...the system that makes sense? The system that the rest of the world uses?

As a programmer, cabinet and furniture maker, I'd have to disagree. you can't divide a metric unit by 3 but you can a yard, a foot or an inch. Powers of 12 work better than 10, giving you much more presicion. Hexadecimal is the only way to go. My house is on a third of an acre, how would you divide a hectacre if you wanted to subdivide it to three equal sized lots?

A mile is 5,280 feet which divided by 3 is 1,760 feet. A kilometer divided by 3 is 333.3333333333333333333333333333333333333333333333 3333333333....

I know up in Canada they did not like me a whole lot because i was not speaking like them. I learned French before English. But on top of french, i have a Boston accent. I dont think that helped the matter! lol

What kind of logic is that?!?! Who divides anything by such an akward number? That's ridiculous! Try Halves, Quarters. Maybe Eighths.
Because your house is a third of a hectare, we should all use the imperial system?
And we aren't talking about programming, or cabinets, or even furniture. We're talking about speed. And how is speed divvied up? in tenths. Like there are 100 centimetres in a metre. 100 metres in a kilometre. ...etc.
Everything is easier done by tenths. Including the temperature outside. Zero......is freezing. 38C is really hot. -44C is really cold.
Don't you think if the majority of the World uses the metric system.....it might make sense for the US to as well. Like...how many feet are in a mile? Isn't it a number of thousand.....with no reaccuring numbers?

Why would you divide a kilometer by three? ...You're going to judge a third of a kilometer? No, a Quarter, or half will certainly suffice. If you divide a Kilometre by 10...it's 100m. Isn't that convenient? If you divide it by a quarter (i.e 25%) you get.....250m! Isn't that simple, and very straightforward?? It makes sense, there are no random numbers.

c'est correct! I use both in my job. I am use to mph, and the way the US does everything.
