I am going to the track tomarrow night, and I will post times with and without the spray when I get home.

 

LOL

Yeah, my raceweight before the turbo but with basic weight recdution was 4960lbs (I weigh 160lbs) or so, I can't remember exactly. After the turbo and other junk it was 5250lbs for sure. This is for the ext. Z71.

Good luck at the track. Can't wait to see what you put up

 

finally got to the track last night. I will post some vids later, but not to bad overall.

1st pass all motor, shut down early (had trouble seeing the finish line due to poor lighting.
RT .5031
60 2.6762
1/8 10.7266 @ 68.49
1/4 16.6007 @ 73.18

2nd pass all motor, dropped tire pressure to 26 psi.
RT .4542
60 2.4183
1/8 10.3307 @ 69.15
1/4 15.9558 @ 84.76

3rd pass dropped tire pressure to 22 psi and sprayed. The spray hit right after the 60 ft, and broke the rear loose! even with a set of 285/75/16 nitto terra graplers!
RT .1120
60 2.6325
1/8 9.8731 @ 77.84
1/4 14.9409 @ 95.10

4th run also on the spray
RT .5112
60 2.4598
1/8 9.7907 @ 75.94
1/4 14.9856 @ 92.88

5th pass this was the last pass I made on the spray. I noticed the spray was not hitting like it should, as soon as I got done with the run I pulled over and found that I have a pinhole leak in my n2o line that goes from the solonoid to the nozzle. There is nothing there that it was rubbing on so I have no clue how it happened.
RT .2465
60 2.4970
1/8 9.9477 @ 74.42
1/4 15.2827 @ 89.66

I made a few more passes on motor after that, and because it was cooling off, the best one that I managed was a 16.0001 @ 85.11. Overall not a bad night, this is the first time I have had the truck out , and also the first time that I have raced an automatic trans vehicle.

 

ttt...

 

here is a link to a vid of the first n2o pass. http://videos.streetfire.net/player....9-E116A863FBA6 it is taking forever to optimize, so it might not work right away.

 

good times... i think those are normal times w/ and w/o the 100 shot.
Cant see the vids tho.. still being optimized.. hopefully they'll be up later today

im guessing its a stock converter too... what rpm were you launching at? like 1200?

 

link is good now
