Well, Have been on the dyno when I can, trying different cam timing with different boost and what not, along with some fuel testing.
The car has made a best of 757rwhp and ~680 ftlbs STD corrected.. dynocom software was giving me some issues and I did not get a screen grab of the graph but I had to back it down some and go from E85 to E50 so I could sping her a little higher without worrying about fueling.
So I pulled ~5* of timing and set her up for some E50, car made right at 686hp and 640ftlbs on a pretty steady 6.8lbs. Packed her up and headed to the track.
First run of the night was
1.66 60'
6.753 1/8th
105.82 mph
10.477 1/4
130.96mph
It spun a little off the line, short shifted to 2nd at 6100rpm and in high gear, hit boost cut that was set at 8.5lbs and fell on its face on the back half.
So I lowered the boost a little, and nudged up the boost cut to 8.8psi and it netted me
1.668 60' <--I spun pretty good
On this pass its still short shifted to 2nd and held 7.3psi - 7.5psi untill the top of 3rd and insto 4 where it hit 8.8psi overboost and fell on its face again.
Car crashed on the track leading to a long cleanup and no more runs for the night.
All in all, not too bad, I was trying to make adjustments a little at a time, to get it to not boost so much in high gear and not fall on its face from hitting over boost, but only got two runs in. I know its got an Easy 10.1-10.2 in it, and If i can get this 60' down, it would have been seen 9.99 tonight.
Old girl still putting out even with almost 54K miles!
