Mine's VX ROM (ECU flash) for Nissan 370Z (Fairlady Z34) 01.01.09

Crash · 01-01-2009, 05:02 PM

It's hard to imagine that a car is street-legal these days without a speed limiter in the US. But it's still possible that it doesn't have one.

Even the V6 camaro had a speed limiter!

(Like at 112MPH or something)

GM limits the cars to what the stock tires are supposed to be rated to. The Trans Ams were limited electronically to 153 on Z rated tires (OEM).

These tires that come on the sport package are R rated. I'd like to see if the Z comes with a limiter because of that fact.

when I get my cobb for the G i will let you know if it is drag limited or not it deff did not feel like it was drag when I had it at 156 mph. so we will see give me until feb when it is suposed to be out for the 09 G

RCZ · 01-01-2009, 10:19 PM

hey, where did it say it was drag limited to 156? a car as aerodynamically slick as the Z with 332hp should be able to go faster than that. That would be my guess.

shumby · 01-01-2009, 10:29 PM

^^^^ calm down no one said you did. There was another thread were we were talking about the different types of speed limiting and that was a point that was brought up.

18rgcelica73 · 01-01-2009, 11:05 PM

Well Car and Driver said it was drag limited. Car and Driver sucks in my opinion

Supergoji · 01-02-2009, 08:32 AM

the E46 M3 can hit 175mph drag limited stock.
the new Z should be able to hit between 175 and 185mph.

hell i remember the Z32 was tested and it's limiter was removed and it hit 170mph+.
i believe.

18rgcelica73 · 01-03-2009, 10:51 AM

I really honestly believe that it is governed to 160, not drag limited.

HIGHLY doubtful it will reach 185. MAYBE it might get to 170-175. My stock Trans Am put a LOT more power and torque down, weighed a hair over 3500 and was pretty aerodynamic for a muscle car. It'd get to about 180 before drag stopped it from pulling. We're talking at least 40HP and 90Lbs of torque more than the stock 370. Once the car got better gears and stuff, I was putting down about 15% more torque. Still limited to about 183. If I'd gotten the long-tubes, full exhaust, better intake and a tune, I may have gotten it to 190.

your car also had a V8 which makes it easier to reach higher speeds

the current 911 base model carrera reaches 180mph with 345hp.
so with a less restrictive exhaust on the 370z it should be able to reach that speed. not to mention it has more aggressive gearing and a higher redline with the mines VX ROM. i doubt it will be 3hp. it will most likely be a 10-20hp peak gain with much larger gains throughout the power band.

Crash · 01-11-2009, 06:48 PM

^^^ My point exactly... With headers, better intake, and a good tune, the Z should be able to reach 180.

BTW, my car had 3.73's. The motor didn't work as hard to get me to higher speeds, but I have to admit, around 150MPH I was doing 4000RPM! Not much more room since it red-lined at 6400. I assume I was doing about 5800 when I hit 180... Couldn't tell EXACTLY how fast I was going since my speedo only went to 155.

Supergoji · 01-13-2009, 07:34 AM

now do you have a 300zx twin turbo?
it's much easier to reach those speeds with bolt on's on a turbo Z hhehe.

400whp is still accessible from our little T25/T2 hybrid turbos haha.
im hoping for 450whp from my stockers, im also going to be running the stock compression from the NA (10.5:1)

Crash · 01-03-2009, 01:47 PM

350HP got my Trans Am to 180+. That was a 3500Lbs car! I'm sure that 332HP with 300 less pounds could do about the same. (Not to mention that the Z is a lot more aerodynamic.)

18rgcelica73 · 01-04-2009, 04:07 PM

Yeah I know. I guess we will just have to find out huh?

Yeah the 345hp C5 Vettes topped out at 177mph if I recall correctly. The V8's in the Trans Am and C5 produce more torque than the Z to go along with that hp so I think the Z aint gonna hit anywhere near 180mph. Not sure of the aero on the C5's but the 370z's .29 COD and 332hp should enable it to hit at "least" 165 to maybe 170mph with no limiter. Assuming the gearing and other variables are in place for that. my worthless 2cents

Zick part.. and gues who has it on their website.
