Why don't we see if we can find a German Z owner and get him to disable the car's governor and go find an Autobahn? :D

Because at 150+ most factory speedometers are off by what would amount to probably 20 horsepower or more.

Ok, how about some telemetry software then? GPS tracking? lol there has to be a relatively cheap and fun way to do this. :roflpuke2:

Yes. GPS and a digital tach readout for confirmation helps.

I can also just give you the answer this Saturday at dinner, since I've already figured it out.

And if the driver dies during testing, then ImportConvert and m4a1mustang, I owe you both a Coke.

I want corrected DA as well as wind-speed noted. :stirthepot:

For the record, I came up with 168mph. I will stick to that +-3mph assuming a non-NISMO 100% stock, manual trans.

Yes, just punch in the torque across the rpm-band at each rpm-point as shown on a dyno graph, gearing, frontal area, CD, and you will get a number very close estimate of the top speed. I have used a program to do this on numerous cars and it's always within 1-2 mph of verified top-speed testing.

While I can't say how fast it would go w/o a govenor, i can say that it was still pulling decent at 150. Not sure how I know this, but i do. ;) I would have to guess a top speed between 160-180 given the space.

The car doesn't have enough HP to hit 180

:iagree: not a chance. getting past 150 is really hard.
