Allright, i found the time (and a not so humid day) to do some runs. Mind you the GtechPRO is relativley simple and i can't get 0-60, 1/8, 1/4 mile times/speeds on the same runs. So i did four runs 0-60 and three 1/4 mile runs.
All of these runs began in four wheel drive and ended in two wheel. Also i had 1/4 tank of gas (~9 gal.)
the four 0-60 runs were like this
1st. 10.78sec -only built ~15lbs of boost before launch, switched to 4x2 at ~30mph (i'm going to thow that whole run out
)
2nd. 9.08sec -held brakes untill boost stopped rising switched to 4x2 around 25
3rd. 9.03sec -same as above
4th. 8.82sec -raised throttle to 2250 then engaged 4x4 --launch had a real kick
Average= 8.976sec
the three 1/4 mile runs went like this:
1st. 16.9sec @ 81.0mph -just like 2 & 3rd 0-60 runs
2nd. 16.6sec @ 83.1mph -ditto
3rd. 16.97sec @ 80.1 -ditto
Average= 16.82 @ 81.4
one note of interest; the 2nd & 4th 0-60, as well as the 2nd 1/4 had a slight (2mph or less) tail wind. and the others had a head wind (i was driving back and forth on the same stretch of road)
Ignoring the huge factor of wind resistence my performance caculator says the 1/8 mile would be ~10.62sec
based on e.t. and 7.8K curb weight i'm rolling with 324 hp to the ground
based on MPH and 7.8K curb i'm getting 328 to the ground. The caculator expected 16.22 @ 84.02 with 360hp and 7.8K lbs
next i'll map out the intervel (sp?) times i.e 20, 30, 40, 50, 60, etc and graph them. i also need to take a look at the shift points and see if it would be better to turn on the tow/haul mode at any time.
