New Times for STS equipt Z71
New Times for STS equipt Z71
For you STS haters please keep my thread clean.
I know there can be more had with a front mount but I'm not ready to swap yet.
I decided to run the truck one more time and see if the water soaking hurt anything. I picked up some C16 on the way there and added 5ga to about 10ga of 91 octane I already had in the tank.
The weather was great and in the 60s most of the day so I knew times would be good if the motor was not hurt too bad.
I got to the track and weighed the beast in at 5100lbs (had over half a tank of gas and my subwoofers inside). So add me in and race weight = 5250lbs
With no adjustments ecept the race gas I went
1st run:
RT: .433
60': 2.14
1/8th:8.41 @ 87.55mph
1/4: 12.92 @ 108.7mph
2nd run:
RT: .090
60': 1.80
1/8th: 7.88 @ 87.5mph
1/4: 12.40@ 108.1mph
Crawled under the truck and turn up the boost by 1psi (hard to tell)
3rd run:
RT: .042
60': 1.85
1/8th: 7.37 @ 87.88mph
1/4: 12.33 @ 110.0mph
The first 2 passes were about 13psi due to the cold temps. When I turned up the boost for the 3rd run I only saw about 13.5-14psi through most of the run but as soon as I hit 3rd gear it hit almost 15psi and stuck there.
Sad this is, the 60' was worse and I was bouncing off the rev limiter on my 2nd to 3rd gear change which hurt a little too.
At that point I felt I still had enough of a cushion to try to up the boost by half a pound and the temps were getting colder so i turn up the methanol for safety and was ready to try again but recieved a call from Rick @ Synergy who had just got a call from Rick Squires and I was told to shut it down and keep it in one piece. Guess there is something going on and I might need the truck to be in working order so I obeyed(sp?) and returned to the pits even though I know I could have went a little faster.
Overall I am VERY excited to finally see some decent #s. I guess the cooler temps and the race gas really did it's work. I can only imagine what I could have done had I used a wideband and some scanning software to make changes and try to max the thing out.
