Gtech the car as an alternative.

Gtech the car as an alternative.

wouldn't that still be subjected to the rev cut?

i don't think so. from what i understand, the rev cut at 6500rpm occurs because the front wheels aren't spinning when the car is dyno-ed.

the gtech device estimates power/torque based on the car's acceleration while being driven along a normal road, so all 4 wheels are spinning and in contact with the ground. the only catch is that adliz has to accurately determine the weight of his car first to calibrate the gtech device.

wow! cool! if that's the case.. the problem can be easily solved.. just drive the car to some shops that have weighing machine for the car

Or.. go to metal scrapyard at defu lane 12

There is more to it. You than have to look at many variations like gradient of the road, tarmac's quality, ambient temps, air density, etc.
