13.65 was dial in. and I broke out big time. 13.491 @ 100 MPH clutch slipping in second gear
I’d go again, and take pictures of time slips, for empirical data, but I’m trying to figure out about the delay valve and if anyone has removed it and made some 1/4 mile runs to verify that a clutch upgrade is needed. The delay valve reduces the initial bite or clamp load that the pressure plate applies the the disc and flywheel. so if I shift fast, it slips and burns up a clutch and flywheel. Any clutch upgrade would need to overcome the delay valve to operate without slipping. Leaving the delay valve in the hydraulic clutch line may enhance the driveability of the car for a daily driver.
