And if so, does anyone know what the actual top speed is (on a stock engine) I have had a 98' and 01' GXE and they both had a speed limiter but if I remember correctly the SE version in the 98' and 01' had a higher speed limiter. What is the top speed of the 04 before it starts to cut out?

I haven't got passed bout 100 yet I'm trying to do the break in proper.

The only limiter I noticed was the stock tires shaking at 130mph. The engine had more in it, but I backed off before it got too bouncy. I don't believe that there is a physical limiting device on the MAX, just the laws of physics. I think the MAX hauls ***** for a car of its size.

Beautiful, cold (-20deg C) day here in Alberta, I am on the highway and not a soul around for miles, took her up to around 220km/hr (just shy of 140mph) and the car ran like it was on rails, seemed like alot of throttle left, but I will have to wait for the next safe opportunity to try again.

supposed to be set at 140 mph. someone claimed to get it tp 150. (but he had 20's on so speedo probably off) I've touched 120 and still felt smooth.

If you dare test the govenor, please get Z rated tires first.

highest i took my baby up to was about 120, she had plenty left in her but i backed down because im a little b*tch thats afraid to get a ticket SMOOOOTH RIDE at 120

CanadianMoFo

I've had mine up to about 230-233km/h before. I backed off the throttle. I'm not sure that there is a speed limiter. I would think that the limit would be whatever the top speed of the stock tires are. Or that there is no limiter as the car will hit a drag/hp limit at some point shy of what the tires are rated for.

So far I've been up to 130mph and it was a very smooth ride. Saw some cars in the distance so I slowed down, otherwise I would have kept going. Read somewhere that it's governed at 140mph. I've been at around 115 - 120 mph on many occasions and it's always felt like a solid ride. In the past I've seen some SL owners saying after 120 it felt a little shaky. Might be due to the tire/suspension/etc differences between the SE and SL.

To my knowledge, the Maxima is limited to 137mph. I remember reading this somewhere but I can't remember where.

Read that the limiter was 139.

I have Yokohama Z rated AVS100's and have taken her to 120 with no problems...

137 is the fastest ive had it to. was pretty smooth too

fstbusa

had my girl up to 130mph indicated actual gps speed was only 125mph

i got 147 on the dyno, stock rims and tires. in my 04 dyno testing the berk intake

maxxoutt

my 2004 maxima,is pretty fast.i got it up to 155.

lightonthehill

maxxoutt - Is that 155 Kilometers per hour, or were you dropped from a plane? Only other explanations are either you coasted out of gear down a very long, very steep descent, or you managed to override Nissan's speed limiting device.

CanadianMoFo

Yeah, I call BS on that one too. Unless his speedometer is out of calibration in the top end. Actual speed is not always what is shown on the speedometer. Often its off by quite a bit once you start to get over 100MPH or so.

I call total since it's his only post ever.

jaydabee

Cite please? How does this supposed goveneror work? I have yet to see a valid cite for a speed govenor on the MAX, just stories from some unremembered source.

Until then I say there is not one and it makes more sense to talk about where it tops out at.

Dealer told me and it's in the specs released by Nissan to the public. I cannot tell you firsthand b/c I never plan on finding out. Do some research on the net. Or email Nissan. I have read both 137 and 140 in car reviews.

i kept mine under 60 for 1200 miles , then my top speed was on the cross island pkwy coming back from a meet i hit 140 , with like 5 maxima's waaaay back in my rearview lol but dont worry guys wont happen again . since then ive rocked steady at about 65-75 always

SilverMax_04

The most detailed product specs I found that Nissan released is their "2004 Product Guide -- Selling Maxima." I have a copy of this brochure which was issued to car salesmen to help them sell the car. While I've not read every word in this copy, I just scanned to find if there is any mention of a speed limiter on the Max. There is no mention of a speed limiter on either the engine or the car. (I would think that the only reasonable way to limit top car speed would be to limit top engine speed -- ie RPM.)

One thing that did surprise me (had not seen this before) when I did this visual scan was the section on "Demonstrating Maxima." The first topic in this section is "Smooth, Powerful Acceleration." In this instruction, the salesman demonstrating an SE with 6-speed should tell the customer: "We'll keep accelerating, taking the engine to redline before we shift gears." This completely contradicts Nissan's recommendation to not exceed 4,000 RPM until the car is broken in. I have not seen any broken-in demonstrators. They demonstrate on the cars they are selling.

Monotaur

I believe that you are correct with regards to limiting the RPM... I remember reading about this from somewhere that was selling a modified ECU (?), in which they pushed the limiter out another 500 RPM (I think they said that after 6KRPM, the stock system starts to limit the fuel supply and at 6.5K they limit it so that the engine cannot turn any faster - the modified component just pushed this out about another 500 RPM).

I may be slightly off in terms of RPM here, but I know I read this somewhere... just don't remember where.

The C & D figures are off. The Max does 0 - 60 in 6.3 secs. aprox. by adding a CAI and free flow cat and rear y pipe, you could drop that 5.8 secs. 1/4 mile in the 14's. 70 - 0 braking stock is around 160 - 170 for the '05's . If you change to aftermarket brembos you could get around 150. The 05 is about the same weight as an 8 cyl. Mustang cause of all the Aluminum. The Max uses Aluminum , plastics and composites almost everywhere...hood, trunk, doors, Engine, suspension, exhaust. There is aluminum and titanium in the tranny and there is chrome and stainless also in the exhaust. The O5 SE has brushed Aluminum accents in the interior...very beautiful IMO. All this sheded weight means the 5 speed Auto is very very fast. If you are going to add a SC I would recommend upgrading the brakes period.

awesome post , but how does it relate to if there is a govenor? post this for the guy that is foolishly considering an Acura

kart1961

The ECU limits top speed to 140mph. The aftermarket chip removes the top speed limiter, bumps up the rev limiter, adjusts the timing, allows the throttle body to open 100% and adjusts the ecu feedback loops. Nissan is tricky with the feedback loops. If u put a CAI on the engine you will feel the difference initially, but the feedback loop will eventually adjust for it and you will not notice the hp gains. I believe it closes the throttle body. Anyway, had a casual conversation with a guy who's friend reprograms the ECUs in socal.

fixxxer

135, but the road was ****, cant say it was the smoothest experience lol

Who sells an ECU upgrade or reflash which removed the limiter and reprograms the ECU? I thought I read about one somewhere, but cant remember where.

jcton20s

I got mine to 140 on the Florida Turnpike. What a f***in RUSH!

max'n

i think 140-145 is about right.i got mine up to 140 with stock rims and 135 with 20's but i did nt push it too much with 20's but i did push it enough.he he...when i did 140 it seemed like it could go a bit more.so i think 145 seems about right.

Here's a cite for ya:

http://www.roadandtrack.com/assets/d...2003155724.pdf

I've had mine up to about 138 before I had to let off the gas for a curve in the highway, but here's an interesting thing. It seems my speedo reads about 2 MPH high. Here's my reasoning. Took my bone stock Maxima SL on a long road trip recently, 2,500 miles total (about 8,000 miles on the odometer at the beginning). Got on the highway, set cruise at 70 MPH, reset the trip computer (miles, and time reading zero, average speed reading *). Checked the trip computer 20 minutes later and it says my average speed was 68 MPH. This was on a long, flat, straight stretch of interstate in Alabama, little to no traffic, never had to disengage the cruise, speed-up, slow-down, anything. For all purposes my speedo needle never moved from the 70 MPH mark the whole time, so why did my trip computer say 68 MPH? I even did the math, time and distance, and it came up 68 MPH. So then I break out the old handheld GPS. I also says 68 MPH. By this reasoning, I could get bigger tires which would raise my actual speed without increasing RPMs, which would make my actual speed more closely match my speedo. Anyone else experience this?

As far as how the govenor works, it's probably the same as I've had on other vehicles, go above the set MPH limit and the ECU lets off the gas for you. My '91 Chevy Baretta GT was limited to 110 that way. If I ever get my Maxima over 140 I'll let you know. Otherwise I doubt anyone has had their stock Maxima over 140.

rnupetroop

If it didn't have a limiter or governor, is it GEARED CORRECTLY to reach over 139 . Someone from Lake Village, Ark says our Max isn't geared right for those top speeds and would get whooped.

A hit dog will holla.

I've only brought mine to 110mph.....nice and smooth ride....

jaydabee

That link dosen't work either.

Could you at least desribe what they are saying and provide a cite to there source.

russgriz

Well, the link works for me at work, it works for me at home, it works at my friends house...maybe you need Adobe Reader? Anyway, this is a data sheet from "Road and Track". It says that the Maxima's top speed is "140 MPH, electronically limited". Who their source is, I don't know. While they have been inaccurate in the past, (stating a limit of 140 where it is really 120) I'd say that the existence of a limiter is a pretty safe bet.

jaydabee - i copied and pasted the link and it does work. The data sheet states that the speed is electronically limited to 140 mph.
