Passport G-Timer comparisons

[T-Mac]

Bought a Passport G-Timer this summer and thought I'd share some numbers at 80 degrees and 38 degrees F. Both calibrations and runs at the same location. Although they are not track times, I use this for comparing numbers as I add mods. Both were with Vector's tune and CAI, and the 38 degree run was with the hsrk kit added. Both runs started just after engine was up to temp, so at 38 degrees I'm not sure if the hsrk came into play or not. Also, the 80 degree run was with 1000 mi. on the odo, and the 38 degree run had 3000 miles on it. That could be part of it too.

.....................80 degrees..................38 degrees.

60 ft. ...............2.20............................2.0 0
0-60 ................6.00............................5. 25
1/4 mi. ............14.48...........................13.82
mph ................92.9.............................9 8.5

Pretty amazing what temps do to the performance. Hopefully next week I'll take the one hour trip to the track for actual numbers, and I'll run the G-Timer to see how accurate it is. Anyway, thought I'd share. :)

Good numbers. :yes:

Do you have the GT1 or GT2 and what are your impressions?

GT2. It's easy to use. Suction cup mount to windshield, one button calibration, and one button to start run. Also gives 1/8 mi. times, 0-10,0-20, 0-30 etc. Will give you HP but the parameters you need to input might not be that accurate to actual dyno HP. I haven't seen a G-Tech, so I can't compare this to others. I'm looking forward to comparing the results with the track slip when I go to see how accurate it really is. I'll post that when I go, hopefully next weekend.
