Before everyone starts throwing rocks at me the 1/4 was measured w/ a g-tech. i ran 5-6 runs in the 13.1-13.3 range and one run at 12.93.
0-60 was 4.43 60ft was 1.75 temp was 62 degrees w/ a strong tailwind.

i have noticed latley that off the line my truck squeals the tires!
i know it's not an official time slip but i don't care!
the next cool day in miami i will take it to the track.

Good Luck getting a cool day in Miami! Where is the local track?

I am up in Boca and also have a GTech. My best 0 to 60 was 4.17 back when the temp dropped to the low 60's. At 3K miles, my times where pretty consistant at 4.8. At 6k, they dropped to 4.5. During the cold snap, I made about 5 runs around 4.2. I have about 60 runs on it and have been amazed at the consistancy in readings during similar conditions.

The one time I had the GTech at Moroso it was registering about .3 under the trap times (13.2 GTech versus 13.5 on the timeslip). Temps were in the mid 70's and my 0 to 60's were 4.6 after the engine was heat soaked.

I attribute the delta to not configuring the GTech to meet the truck's specs (pitch, drag, etc.). I look at the numbers as an indication of performance increase when the road and conditions are the same.

closest is Moroso. but I am dying for a cold day. i usualy just run it on ockechobee (spelling?) road.

That same day i got smoked from a roll (fender length) by a n/a civic. off the line i took him by like 7-8 cars. lol.
i'm still trying to find the best technique to race while at a roll, you'll be amazed at how everyone who talks smack about how their car is soooo fast will only race you from a roll... i wonder why?
