Last weekend at a big Ford vs Buick event, one of my 'tamer customers went 10.34, 10.32, 10.30, 10.36. Final round slip was 10.362 @ 127.89 with a 1.415 60' for the win.
Another 'tamer customer was out testing some 26x8.5 radials on his Mustang, 10.09 @ 128.98 with a 1.334 60'
Yet another had just installed my new all hydraulic system on his C6 Corvette. He got 5 1.43 60's in a row but didn't get a full pull due to power cut problem. Turns out the car's torque management system cuts the power output until a clutch pedal switch senses the pedal has fully returned after a shift. Next time out he's going to tape the switch down.
Did I mention Pat Norcia of Ram Clutches just picked up one of my new hydraulic systems for a 2019 Mustang :)
All the above cars have diaphragm PPs.
