the acceleration figures seem to be OK. You can definitely see the effect of launch techniques (clutch/wheel spin, rpm etc).

Very good is the braking distance measurement as well.

The HP measurement, I do not bother. The actual weight of the car is required and unless you have access to a weighting scale you simply do not know it!

THe way G-Tech works (measures longitutinal acceleration & integrates wrt time to find speed) makes it makes it easy to fool it & display wrong numbers:

If you do your test in a slightly uphill G-Tech thinks you go (accelerate) actually faster than you you really do, and displays very optimistic numbers!

It is a nice gadget to have, but requires very much attention to detail to get meaningfull results. The same is, however, true for all performance measurement devices, no matter their price!

Nice fun to get your friends together and see who can post the best acceleration on the same car / same conditions!
