with stories like these, makes you wonder if Nissan is doing something wrong by not limiting cars such as the GLE's at 131mph (Maximum for the OEM's H-rated tires)

how can i find out the diff in the speedo with my tires?

LatinMax

Most of the cars I think are limited to lack of HP because of the drag factor. I maxed out at about 130 driving to Austin (Texas lots of open highways) and then after the supercharger and bodykit went up to 155 befor I got nervous and let up.
So that is the reason for my thought process. Oh I have a 2000 auto

130 in my '96. 120 to 130 didn't seem to take more than 3 or 4 seconds. I decided to slow down for no apparent reason and got a ticket at 86. Ouch.

I haven't sped in two years now.

I hit just shy of 150 racing a Porsche Boxster (you guys would be VERY glad to know I kicked his a$$!: gotta love beltway driving in DC...). I have an '03 SE with auto. At the time it was bare-bones stock. The best part: we had four people in my car: the boxster: 2.

Oh ya, to all you hatas out there complaining about speed: it was at 4am on a Saturday on a 8 lane highway with nobody else in sight.

is there correlation to the car's trim level, type of tranny, and the OEM tires the car came with?
2000 gxe with stock 15"s I did 135mph once and still didnt hit the limiter....

While this discussion has been discussed before, there is no clear answer. SR20DEN's 6 speed 3.5L Maxima has a top speed that he can't get past, while my 6 speed 3.5L Maxima doesn't. There's no rhyme or reason, except that I have a dyno to prove that my car hit 157 MPH in 5th gear at just over 6500 RPMS and was still pulling. We shut it down because my tires are only speed rated to 168 MPH, and I didn't want to run the risk of anything happening to the car or the shop where I was at.

According to most research, the 6MT 3.5L Maximas don't (or shouldn't) have speed limiters. They have fuel cuts at about 6600 RPMs, but no speed limiter. The 4MT 3.5L Maximas have a speed limiter at (or around) 137 MPH, but there are a few vehicles in both situations that don't meet the rules above.

yes i agree, for some reason there are huge variances, and probably several reasons. I can attest the little things do make a difference, i did my intake, cat back, y-pipe, and test pipe all at different times, and i can guarantee i difference in top speed each time, the cat-back took me from 140 to 142, then the intake to 145, which is obvious because the short ram adds more top end than torque. The additions may only be a couple mph here and there, but you also need to take into account conditions. On a clear crisp night i can hit 145 all day long, i'd put money on it. But then one night a couple hours after a storm, the Barometric pressure was down around 29.5, humidity near 90, and the temp in the mid 60s, and i only hit 137. Even tire pressure, i run better up top with 44 lbs hot pressure, ~38 cold on 235/45/ZR17. And those speeds are corrected for the shorter tire, my speedo on average reads 3mph over actual, clocked in distance, and verified by GPS at 250 ft above sea level.

In that pic I posted above: That speed was held for uphill, downhill, flat, so it is without a doubt the governed speed.Car was pulling fairly hard when hitting the governer, it's limited because the tires are rated to 130 (hence the 129 limit). HP is not an issue

GreenSeMax

do you have 16s or 17s?

I think what he was trying to convey, is that if you want to blast down a vacant road in the middle of nowhere, where you will only be a risk to yourself and woodland creatures, then we can't stop you. But you should NEVER involve others in your irrational and uncontrollable behavior. If you want to have a little "fun" on the street every once in a while, then I think it's ok within reason. But once you involve the well being of others, game over.

If you want an addrinalin rush, go sky diving. It's cheaper and safer.

Mine also, It was still pulling (temperature outside was 5 degree's) and a slight downhill and then I hit a little limiter, the car slowed down a bit, accelerated again and then sustained that speed for a couple seconds before I decided to slow down, it just wouldn't go after 131mph and even held that speed in 4th gear.

dude why do you guys all think that cars should limited at their tires rating. sure it's a logical idea, but those ratings are after an hour FACT. i guarantee you no one on god's green earth will go that fast for an hour. so whoever was on the dyno hitting 150 something...POP THAT **** INTO 6TH!!!

sidenote: one of my friends with a 97 gle hit like ~140 with two other people in ther car (i wasn't one of them) and yes he got a ticket lol i personally haven't even tried going over 120. the last time i even broke three digits was probably last year (gotta get some points off)

It makes no difference. If i was running on 12" wheels, the car would stop at a speedometer readout of 129 still cause of how its calibrated. it reads __ revolutions in __ time = __ mph. If my little dinky wheels are turning with the same rotational speed (radians/second) as my 17's, the car thinks i'm goin 129. Might only really be doin 90 mph, car computer doesnt know the difference

[\QUOTE]

Doesnt matter to your average consumer. The tire is rated for 130, that's all we see. No details on temp, pressure, duration, size of tire (all which would affect the stresses put on the tire). But on a dyno, I see your point... knowing about the centrifugal acceleration tho, i'll continue to play it safe and not push my tires.

Have you seen the kind of people that race at 140mph in traffic

bigdo26

iTrader: (3)

who said there was traffic? 2 am = no cars

GreenSeMax

yeah 384 is sweet at night, and btw i know the wheels won't change the ecu, however you can recalibrate it, and i asked what size wheels because the speed rating is different on the factory equip tires. Personally I find it rediculous that they can limit the car to begin with. And as far as the rating is concerned, some people do sustain high speed, i traveled at 140+ for about 50 minutes once, covered like 2/3 of N. carolina.

Gotta love DC's beltway! I've done about 150 racing a Boxster at 4 am between the Clara-Barton Parkway and 270. We did 100 down the parkway. Scary stuff!

In the law-suit hungry country we live, where american drug manufacturers won't make life saving flu-vaccine because of liability exposure. I'm suprised the major car companies, in fear of liability, don't set the speed limiters at 70mph!!! I can imagine someone being paralized as the result of a 120mph wreck in their riced out civic, sueing honda for letting them go that fast.

just my .02 cents

Was able to get up to 140 drove like that for less than two minutes, did not hit any limiter, the car definitely could go faster, but that was enough for my first time going that fast. i'd like to try to get it up to 150 the next time i'll find enough of the open road.

140 in my 01 5speed more than once. Thats when she shuts down.

yes, yes it is! Rt 89 in NH/VT is awsome too, basically a dead road.
On a side note: I find it is much more fun to push the car on the twisties than pushing it for highway speed. Honestly, 100 doesnt really feel fast, just a quick cruising speed. ON the twisty roads tho, now that is fun. I now realize what "body roll" really is. Need some suspension upgrades

joebangaa

iTrader: (3)

truthfully i think that's partially the reason why they make you look up the stupid speed index and they mess up the order (you know how Y-rated are much higher rated than z blah blah). But in any case, out of all the consumers, how many of them actually look into the top speed of their vehicle and the speed rating of their tire? anyway, i personally wouldn't worry about the tire just shredding into pieces at high speeds unless of course the tread is absolutely gone and you got metal wire shards stickin out. If i had a dyno i'd for sure test out my top speed haha. too bad for me all i get to play with are toll roads

and yes, i'm running h-rated tires right now and i wouldn't hesistate to top out my car if i had the chance (not on open roads)

around 130 on my auto SE

I hit 140 easily with my 2002. I don't know.

All GXE, GLE and SE autos have speed limiters at 130MPH set from the factory.
SE ( and the 20th Aniv ) with the 17" wheels and 5spd manual tranny do not have a speed limiter at all. 3.5L autos have 130MPH speed limiters and non LSD 6spds are at 149MPH, the LSD cars do not have a speed limiter. How do I know this ? I worked for Nissan and when you need to reprogram the ECU, it asks you if the car has V rated 149MPH tires or not. Reason Nissan didn't put a limiter on the V rated tire 17" wheeled 5spd Maxima- they knew it didn't have enough power to do 149+MPH. My car hits a nasty speed limiter at 135MPH indicated on the speedo, and I learned to know that the speedos are not calibrated for speeds over 100MPH as they are for under 100MPH. For everyone who hits a speed limiter, look at your RPMs- where are they at ? I have tried hooking up a Apexi Rev Speed meter to my car, and I was able to go do 155MPH on I355 racing a supercharged 96 SS Impala with a state trooper "trying" to catch up to us in a Crown Vic a while ago. My car feels just as stable with big tires and good suspension at 150MPH as it does at 60MPH. So whomever says they did over 130MPH in their auto Maxima.... they are being lied to by their speedo, or they try to show of on the forum sayn they went 170MPH. 159MPH is Max 3.0L 5spd will do on stock redline, so going past that is currently not possible as no ECU upgrade is avalible for us.
