HAHAHA... *deep breath* HAHAHAHAHAHAHA...
Doesn't work that way. On cars that are are fuel injected are all equipped with ECM governors that limit your speed to 155 mph regardless (North America only). There is no way around it except reflashing the ECM. Cars with carburetors had governors that were attached to the flywheel and pulled back the flaps shut once the airflow got high enough.
Plus if there really was a "trick" to allow your car to go past the 155 mph... and make it that easy... the car companies can easily be sued because it's very illegal to sell cars in the USA without a rev limiter. Cars are rev limited to 155 for good reason. If you go past 155 mph on stock tires... they will burst... causing a massive accident.
So no, there is no "trick" around a rev limiter or governor unless you disable it yourself.

Removing it isn't supposed to be hard, if you really want to hit those speeds. However as TMR(N) said,get racing tires mkae?

its very possible its a trick designed for the soft limiter, i live in jersey and have yet to have a road empty enough and without worry of cops enough to hit the soft limit of 144/5 on my g35 ive only been able to find space to get it up to 130 and im stuck dealing with other assholes whilst doing that.

The G35 (I'm assuming coupe?) is electronically governed to 155 mph. You cannot go past 155 mph no matter what you do. There is no trick, there is no "method" or anything like that. Trust me, if there was a trick, people would figure it out and post videos on youtube of them doing it. First proving that there is actually an electronic limiter still in effect, then doing the "trick" to show that they can get past it. The only way to get past 155 mph is to remove the limit completely.
BTW, you know if don't have Z rated tires on your car (I know you definitely don't have W or Y rated) then I wouldn't recommend going past 135 mph. Your tires can and WILL burst if you use lower rated tires and try to achieve 155 mph (especially on NJ roads...).

Uhm, I'm not trying to be a wiseass, but since I am a Performance Car enthusiast and a Racer, I would like to explain some things, because it seems some of you are rather misinformed or are basically spouting urban legend.
A "Rev Limiter" and a "Speed Governor" are two totally different things. Yes, they might or do work in cooperation or one might be activated by the other, but they are different things with different functions.
A rev limiter only prevents your engine from reving over its red line. Let's say you are brake torquing for a hole shot at a stop light like some dipshit teenager that just got their license, if the engine revs over its red line, there are strong chances that the engine will shoot a piston, rod or valves through the hood or spit the crank mains through the oil pan. YES, things like that are funny to see, usually when some nooby gear head chips the car and/or removes the valve body inhibitor and tosses a Nox shot into the manifold, without bothering to build the engine to withstand the much higher stresses or strains. Now, the primary reason for the rev limiter is if the engine red lines and blows, guess what? That would fall under warranty and the manufacturer would have to fix it.
As far as speed governors are concerned, those limit the top speed of the car. Where ever you got the 155mph governor is nothing but a random #[*EDIT* actually 155 is only the most upper extreme in Speed Governors in N.American Production cars]. The top speed limit is not only given from the production equipped speed rated tires which unless are extremely high end sports cars with tires having Z or ZR rating, Z being in the 165+ range and the ZR being in the 186+ range, the next rating below 165 is for speeds below 149 (which is what the major majority of production sports cars are equipped with, so 155 would be too little too late). The majority of speed governors on passenger cars are between 102 and 145.
Aside from the tire speed rating, a much more important factor in deciding speed limitations is aerodynamics. Take the Buick Grand National for example, its Speed Governor was set to 124mph. That car can be easily made to do 200+mph, BUT since it has the aerodynamics of a retarded shoe box, when the car hit 130+ there was enough air lift underneath it to lift it almost completely off the ground, which as anyone could imagine is not a good thing. To be able to withstand higher speeds, there has to be a lot invested in aero mods. If you've ever been in an unmoded car, that doesn't have good aerodynamic design, going 100+ mph, it's very easy to feel the car starting to get lift, like a plane at take off.
If you have even remedial knowledge in gear headin, ditching rev and speed limiters is a Sunday picnic, BUT those things are there for reasons that usually surpass just remedial knowledge.
As far as street racing goes, yeah, daytime on crowded highways is the god please kill me or send me to jail prayer.
As far as "fun", hell yeah it is and the "illegality" is part of that fun. I've been a racer since I was 6 years old when got my first minibike, BUT any self respecting street racer, does not endanger "civilians". I mean when I was in High School, there were a bunch of Street Racing crews, but we used to do it on freshly paved roads in the middle of cornfields (farm land) in the middle of the night. Barren and empty is how we liked it. You could see car lights coming from miles away, so the only people in danger were our own dumbass selves and our idiot friends that were in for the ride.
Where I live, going 29 over is reckless endangerment, racing is instant suspension/revocation, both with possible Jail time so the big fines are the least of your worries. Plus if you get into an accident, there are charges like attempted negligent homicide, awaiting you which is a nice felony record. Things are not quite like they were 20 or more years ago, when I was getting speed tickets for doing 2-3 times the speed limit and only getting a 50 dollar fine as well as maybe once every few months I couldn't sleep in on the weekend, because I had to go another "traffic SAFETY school" course (god I went to so many of those I think I got a Doctorate in traffic safety school).
As with all things there is the right and wrong time and place to do things. What those kids were doing were both the WRONG place and the WRONG time to be doing those things.

You are quite wrong. The Speed Governor,as well as the Rev Limiter, on the Infinity Gs are programmed into the ECM chip (very common on all modern ECM cars). There are aftermarket chips, specifically for Make&Model, like Infinity G35, that can add up to 50HP and the also remove the speed limiter. You can also get chips and warez where you plug your ECM into a laptop and specifically program your chip for your requirements, which is usually what is done by diehard gearheads, because you program for things like the variable valve timing to correspond to the turbo boost spectrum and for things like running Nox or Nitro Meth fuel mixtures or for mods done to internal engine components like Cams and Valves, etc. These "tricks" have been around since about the time these ECMs and Chips started being used in production.

I don't want to sound like a dickhead or anything... but you are pretty misinformed about cars...
Understanding the Rev Limiter
--- Quote ---Ford installed a Rev Limiter (a.k.a. RPM Limiter, a.k.a. Engine Governor Assembly in Ford speak) in the 1969 and 1970 BOSS 302 Mustangs and Cougar Eliminators. The Rev Limiter's function was to limit the engine RPMs (pretty obvious by the name) below 6,150. Go over 6,150 and the engine started to misfire.

--- Quote ---Take a look at the drawing (schematic) below. It shows the basic ignition circuitry including the Rev Limiter (Engine Governor Assembly). The Rev Limiter monitors the "DIST" terminal on the coil. The discrete and transistorized circuitry inside the Rev Limiter picks up the ignition pulses and "calculates" (without a microprocessor!) the engine RPM. When the Rev Limiter determines the RPM is greater than the limit (6,150 for BOSS 302) it switches (using solid state technology) a load onto the "DIST" line. The power is shunted away from the "DIST" terminal to ground. This causes a misfire or, actually, a no fire. Grounding this terminal prevents the high voltage build up and release from the secondary coil (HV) to the center distributor cap lead for the spark plugs. Maybe you have seen or heard of the same effect caused by one or both points in the distributor stuck closed or a bad distributor capacitor (condenser) providing a path to ground.

Don't believe me? Or that diagram too "simple" for you?
(click to show/hide)
Look for the Overdrive Relay and the Overdrive Kickdown Switch... Then follow the "White" wire out from the Overdrive Kickdown Switch to.... OMG! The Overdrive Governor! Wait... this is an entire electrical diagram? Where is the Rev limiters?
Governor = Rev limiter... ::)
Most modern cars though have the "Rev Limiter" or "Governor" installed with the ICS (or Ignition Control System). That is why it's really easy to reflash your car's ECU to remove the electronic governor on your car... and also why it is extremely easy to reprogram the actual limit the engine will rev to.
EDIT:
If you don't know... ECU is Engine Control Unit.
