new best 1/8 time tonight- bitter/sweet
I met up with KBracing and GMCTRK at the local 1/8 tonight. drove in and dropped the tire pressure to 17psi and shot the **** with them for 20-30 minutes.
pass 1:
1.47 60'
6.85 1/8
100mph
I was excited about the 60' time, but it was supposed to be my baseline pass before giving it a little more power (atleast I hoped to give it more power)
I lightly touched the rev limiter on the 2/3 shift so I dug into the transmission table to get it fixed and found that I'm only shifting 6,800 rpm and this combo should hit a sweet spot around 7,200 rpm or so. I got even more excited! bumped the shifts to 6200, rev limiter at 7,500 rpm. I also went ahead and gave it 2* more timing across the board as I am still on my baseline tune that I first started the truck up on (hense the 6800 shift point that I didn't know about)
in the burn box I felt the motor missing. never done that. it **** all over itself and I aborted the pass. didn't even look at the slip. thinking it had to do something with my changes I backed everything back but kept the shift point at 7100. same ****, different pass. my ignition box is only seeing 12.7-13.2ish with the truck running. it's never done this **** before but it has me pissed. I was ready to get a good pass in
oh well, a new best without changing **** and finally dipped into the 1.4 range on drag radials. not bad for the 3rd trip to the track.
