It's not gearing you run out of, it's power. It takes quite a bit of it to move all of that air out of the way.

What track can hit 155mph in the US on a NA 370z? I hit 150 or so in my Corvette at VIR, I think about 155 or so at the Glen.

Daytona?

Do you live next to the Autobahn? If not, who cares what the top speed is. You won't even hit 165mph on a track.

hehe for some reason i had it in my head that the z could do 200mph + but couldn't due to the limiter... the difference between the 155 and 165 is so minimal, why limit at all...

Does anybody know the magic incantation (button/key sequence) to disable the above. I'm assuming it must be possible, or it's a bit of an oversight on such as wonderful car.
Sick to death of watching the back end of a 911..!
(I have mega-speed rated racing-spec. tyres on order).

Better still, is there a full list anywhere of known parameters the user can tweak stuff with?

I have the one that seems to re-arm the SRS after routine maintenance (fitting of parking sensors) to start the thread off:

- Sit in drivers seat with key.
- Without foot on brake, press start button twice quickly to turn on ignition, all lights on dashboard illuminate.
- Wait until all lights go out, and BEFORE SRS light starts blinking (gota be quick), then press start button again one more time QUICKLY.
- Repeat above 3 steps 3 times. voilà! Re-armed SRS.

(There might be more to it, but it worked fine for my new 2010 GT 370z)

Failing the usual 'front door' config, does anybody use products such as this with an luck; seems to be just the ticket for a lot of things:

So what was the rpm at when you hit 155? I assume you were in 6th gear

It's because it's there, I'm talking about an hours fun on a track once per month. On open roads I'm a staunch safety nut.

It's all relative and what you are used to. I lived in Germany for 6 years working on the US Airbases (i'm ex Forces), and used to drive to work at 195mph, and that's only 'cos my BMW topped out there. I used to get overtaken at that speed. You'd slow down to turn off the Autobahn to 120mph.

Their 'slow lane' would typically average 110/120mph, and the fast lane whatever you liked as long as you were in control of your vehicle. You'd get arrested for being rubbish at 70 far more likely by the Police who would ignore you at 200+ - they'd even pull over to get out of your way.

However, the price for that fredom was a driving test that was very hard to pass, probably the hardest in the world IMHO.

So, I can 'park' at 130, whereas you chaps have to suffer having an infrastructure set up to the lowest common denominator. Don't get me wrong, your system is GREAT, and I love it ever time I come over, and yours is miles better than any other I've been on particularly the UK system with it's outdated lane priority model. But it does tend to over-sensitize you chaps to a few extra MPH and have your eyes glued to your speedos instead of looking out of the window.

Regards,
Al.

It's simple math. Weighing in at 3300 lbs and having 332 hp means you aren't going to get anywhere close to 200 mph. You would need almost 600 hp.

It could be worse, in Japan all new cars are factory limited to 180 km/h, (111 mph).

Thanks for the programmer tips. L8a.

I guess you don't know much about air resistance!

What model BMW did you drive that hi 195 mph? Oh, maybe you mean kph?

Slow lane average on autobahn 110/120 mph? Bullcrap. What drugs are you on?

Maybe your engine is dirty? Try the Engine Scrub [ESCRB1] - $9.99 : KaleCoAuto, Hard to find automotive items! to clean your dirty engine!

Also, your engine is probably too hot...it's a simple matter of physics that energy is lost through heat! The Radiator Insulator - $199.95 : KaleCoAuto, Hard to find automotive items! should take care of that.

And if all else fails, try this Flux Capacitor [FLUX62] - $175,000.00 : KaleCoAuto, Hard to find automotive items!

Good Luck!

This is truly an amazing product. I bought one. I can do 0-60 in minus 4.7 seconds!!! Yes, -4.7 seconds. And the neatest thing about that? You can look in your rearview and see yourself at the start line! It's for sale becuase my Z is too fast for this planet. PM me and let's talk price!

Hey just be thankful we have that high-performance lightweight paint, otherwise we wouldn't be able to break 140mph.

Vegitto-kun · 03-17-2010, 09:29 AM

I think the TG guys said that for example the Bugatti veyron only needs about 270 HP for 155 mph but it needs the rest to go faster because of air resistance

This isnt where I parked my car
