Finally got to open up my car last night. A little disapointed that I could go past 210 kph (130mph). I was only reving at 4500 and I know there is room for more. Anyone know how to get around this limiter.

Also, a question ... What's faster for takeoff TCS on or off???

Ive heard you can't get around the limiter without getting an aftermarket ECU or something....I dunno someone else should know.

Your launches will be faster with the traction control off.

130mph? that's it?

that's weird...

i got mine up to 145mph, and it was still going, but i was too afraid to get caught by a po-po.

I believe the 3.5 auto's are limited to 130 mph but the 3.5 manual's are not.

Has to do with the tire speed rating. The OEM auto tires are only rated to 130 I think (hence the limiter), but the OEM manual ones are V-rated which is pretty high.

If a vehicle is capable of speeds higher than the OEM tire that a manufacturer is equipping a vehicle with, then they must install a speed limiting device...

If you are a good Driver TCS is going to be slower.
The only thing it can do is cut power to the engine, and that screws up the power curve.
Turn it off and push the pedal to the floor as quickly as you can without spinning the wheels. If you let up on the pedel and hit it again, it is no better than the TCS.

TCS is only useful in the rain or snow and you have the windows up and can't really tell if the tires are spinning.

I'll bet there's a way to remove the speedlimiter on the Auto's. There's a similar problem with 2nd generation FWD DSM's. The AWD's didn't have a speed limiter, but the FWD's did. Upon further investigation, there was an extra resistor that was missing in the FWD ECU. Adding the second resistor to match the AWD ECU removed the speed limiter. I would wager the same can be done to the Auto ECU's for our cars. Find somebody with a 5 speed ECU and compare it to your Auto ECU. If the differences are nothing but a resistor... VIOLA!

Just make sure you upgrade those H-rated tires before you make any banzai top-speed runs. Blowout at 141 mph = Bad.

I didn't say I was going to make a top speed run! I just said, "I'm sure there's a way to remove the limiter." Damn Nissan and their Bridgestone Turanzas.... sheesh!

The last time I went 150+ mph in a car, I blew the motor in my Talon. Ain't doing that again......

Disappointed??!! WTF!

How much faster did you want to go? Seriously, how disappointing is it that your car can ONLY go 130MPH.

If you are driving even close to this fast on public streets on a fairly regular basis, this whole thing becomes a non-issue. Soon you will be dead or in jail and the top speed of your altima will be the least of your concerns either way.

I don't know how much per tire Nissan saved by sticking the H-rated jobs on the automatic 3.5s versus the V-rated tires on the manual 3.5s, but I'll bet I could count it in dollars on one hand.

*Way* cheap.

They ran out of corners to cut and money to save on the interior so they had to look elsewhere...

a cheap shot, yes, I know

 

[jkwright]

Oooohhh, that's a cheap shot indeed. It's true, yes, but very cheap.

The good thing is that Ghosn didn't scrimp in the sound-deadening department. That would've been a real bummer, Steve.

Speed Rating basic.

Speed Rating is not how fast the tire will spin and not fall apart.
Speed Rating is more of a load rating/heat dissipation.

A fully loaded tire will run at the Speed Rating constantly without overheating and thus seperate the plys.

An H speed rated tire will handle 140+ on the altima because it is not fully loaded. (4 * approx. 1200lbs = 4800lbs)

How often do you drive above 130, and for how long?

When I replace my tires I will be saving the $160 and buy the H rated tires.
