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.

 

Good with the bad, but at least it was a semi-successful outing.

 

Damn strong sixty foot. Truck is bad *** !!!

 

awesome 60'! 1.4xxs are fun! good luck with figuring out the issues.

 

i'm hoping it's a battery or alternator. the ignition box is reading low voltage. worst case is i have to send the ignition box for an inspection/rebuild. i'm hoping the 60' gets even better once i grab onto the trans brake.

 

Wow man that truck is movin and looks like it's not done , congrats .

I've been there , ready to make a pass and stuff just isn't right , that sucks , but you'll bounce back once ya get the bugs worked out .

Any vid from that night ? I'd like to hear that LS singing around 7k

 

nobody caught the first pass. hanging the front tires in the air on drag radials is a feeling I never thought I would get.

 

That is sweet. Too bad no video.

 

Like your first ******* huh ?
