Going for nines tomorrow
I'm headed out tomorrow night to try to eek into the 9s.
I will still be full interior with cats as I try to get it nudged in there. Last week when I ran I was too busy to give my full attention to my car but this time it will be my full focus. I was able to get my afr reasonable close to commanded in just a couple of runs. this week the changes I will make are:
Installed 315 hoosiers on the c5Z fronts(I hooked dead with my old tires last week so no gain here)
Lowered the 1-2 shift to hopefully 6850 from 7090
Will try to find out where knock retard is coming from even with mild advance
Perhaps creep up to 12.3-12.4 AFR from 11.8
experiment with ***** out launches with the wider tires
What air pressure are those who run this combo running? I ran 20 psi with the 275s(which worked awesome 1.330 60' last week). I don't like how wrapped around the tread is on these wheels. I'm afraid I may have to drop the pressure to 15 or even less to have a shot a the full contact patch...On the plus is that if I do they will be shorter and help with the 3.42s.
Any ideas? If all goes well I will have a 9.97 time slip
