Went to the track today to test out my new posi i put on saturday. I'm at 5800FT. A lightning ran a 15.02 with a couple mods. I hooked well. Here are the results with the TrueTrac:


60'..... 2.232
1/8.....9.581
MPH....75.26
1000...12.457
E.T....14.918
MPH....91.73



My previous best before Truetrac was:

60'.....2.517
1/8.....10.031
mph.....74.31
1000.....12.930
1/4.....15.407
mph.....91.22


by the way it was with 20" centerlines

 

Woo, thats the kind of gains im looking for when I take mine to the track!

 

Congrats on the new best, that mountain air really puts a damnper on it.

 

Wow, nice improvement, so the only difference was teh TruTrac?

 

Yes, on the previous best i ran the truck with the stock wheels. This was with 20" centerlines

 

Good run, I wonder what it would do at, or near sea level?

 

I went to the correction table and it shows it would be at 14.0. I still need to tune it more, Don't have the wideband yet.

 

Nice improvement with the true track. I plan to eventually get rid of the G80. Got 56,000 miles on my truck and I'm on my second G80. Did you have G80 before or was it open diff, my guess would be open looking at the difference in 60ft times. Now that you got new posi, you can replace that TB Stall with say a 2800 - 3000 converter and get those 60ft better.

 

nice gains!

 

it was open diff. yea i plan on replacing the stall with a bigger one. it only stalls up to like 1900
