still working out the 60' on the 87 ttop at low boost before stepping it up
the 86 has some upgrades since last runs and should go faster but for now i'm working on the 87ttop
murphsters been taking video of the launches so i have something to see and a couple things need some tweaking , and looking over the logs to see the little things i might overlook and its getting better.
still only running 1/8 passes on a 1/4 track (etown racewaypark) . lifting at 1/8th and grabbing the brakes all runs so far have been low 10s at under 90mph
last wed was the first time the new setup had been down the track . after the first test run pass of 1.43 110mph 1/8 mile everything felt good so i held through for a 1/4 mi on second run and it went 1.47 6.3@111.7 9.82 @ 139 ... at 20.6psi
i replaced the gate spring from a 6# to a 3# so i could lower the launch boost to 5psi. i got 2 passes tonight before the rain came . 1.44-1.43 60's ,. and still running low boost.
1.442
4.035
6.218 @ 112.27
second pass i managed to keep my foot down but i left early at 5psi and didnt have the rpm up , still ...
1.435
4.013
6.183 @ 113.27
should run out 1/4 in the 9.6s but want to work the 60' better before i turn it up and let it go a full pass
109 , 235cu, 71hpq 4bolt , GN1's, xfi 2.0, th400, 93 and alky
faster times to come....
