I know he does go to Irwindale. Don't know how often. He has been in the high 5s in the 8th. More often it's in the low 6s. At the Pinks event, he was having problems. High 9s if I remember right.
Correction. Don't want to get on Jim's bad side. His best was high 9.5s that weekend. John's Mustang was at the 9.20s. Duncan's Camaro was detuned to the area of 9.20s and Jason's belt driven, centrifugal blown, big SBF was in the high 8s. He desperately tried to detune the car, but to no avail.
