After some late night racing the last few nights, I hit up the track today. The stock th400 didn't like me all weekend, and won't give a 1-2 WOT shift at all, can't complain too much, I paid $250 for the transmission. Drove it about 500 miles this weekend, beat the crap out of it, and drove it to and from the track...

First pass, 8lbs, 16 degrees timing, 91 pump gas, soft launch, lifting for a 1-2 shift

1.69 60ft
7.24 1/8
97.22
11.26
122.05

Next pass, 8lbs in 1st, 10.5 lbs in 2nd and 3rd, 16 degrees timing, 91 pump gas

1.64 60ft
7.088
99.68
11.009
125.27

Next pass, hot lapped, tranny really hated me

1.68
7.197
98.56
11.146
124.61

I then had my electric waterpump die on me. I went to a buddies house, pulled his off his car, and swapped it out at the track. I put in 110 gas mix with the 91 octane, threw on a new tune I wrote...bumped the timing to 24 degrees, added a little fuel so I could up the boost.

Still 8lbs in 1st, and 10.5 in 2nd and 3rd, lifting pretty good to get my 1-2 shift, running a little rich on the top end.

1.60
6.999
99.91
10.90
125.64

Final pass, hot lapped it, 8lbs in 1st, 11.5 in 2nd and 3rd, lifting for my 1-2 shift

1.56
6.94
100.07
10.80
127.82

Here is a video my buddy made from the track today...

That et and mph on the stock heads, stock cam, stock tb, stock pcm tuned by me, and stock intake makes me really happy, especially since I run the stock wheels and the car sounds like a stock lt1 with a catback when I'm not wot. Oh, plus it's currently my daily driver. I think had the tranny shifted correctly then I could've ran the 11lbs in 1st and went a 10.6x without much issue, not shabby for a 3500lb car.(weighed it at that)

I don't think adding the 8 degrees of timing really helped me much honestly, it's going back to the super safe 16 degrees and staying there.

I wish I could've found some 60lb injectors, I made these passes on 42lb ford green top injectors, 68 psi fuel pressure at wot, maxed out. Plus the maf is maxed out rather quickly, I'm still on the stock pcm tuned by myself also.

I have megasquirt sitting here to go on the car, then it will get some 96lb injectors, and a complete fuel system. Hopefully spring time it will go 9's on the stock heads/cam/intake/tb....in a STREET CAR

 

amazing, you know 10..maybe even 5 years ago I would have told you that was impossible.

 

WOOP WOOP.... ltx pwn... haha

 

Nice work Justin!! Get a rebuilt tranny and click off 10.5 @ 130mph as it sits.

 

Very impressive!

 

Congrats man that is really hauling the mail.

 

Damn impressive!
