The gurus over at
www.TurboDodge.com can answer some questions. If its running good expect low 16's high 15's. If its running great, 14,s are common. Tweeked a bunch and 10's have been reported.
The cams in these are VERY mild. 240 In 244 ex with 0.430 lift. Just advancing them 5 degrees helps some. I was running a 260 deg at 0.460 lift. Was quite a wake up for that car.
Some 85's did have Turbo issues, agian TurboDodge has answers.
If its a 5 speed, it has an A-525. Killer OD with 3.56:1 Ring and Pinion gears. Not enough tire, you'll find out.
