I'm on a quest for 11.7 or better on street rubber. This trip to the strip resulted in 3 high 11 sec runs, 3 12.0xxx sec runs, and the rest low 12 sec runs. My best time was 11.8479, a personal record in this car. See below for time slip data and video links. Sorry, no GoPro video this time. I only got 6 PDR videos out of the 11 passes - too busy disabling nannies after line lock. Only have 8 of 11 passes on spectator video too - my grandson was doing his homework and missed 3 of them. As always, I don't look to see who's in the next lane until I review the videos so I may have mis-identified some cars.
[UPDATE 20170422] Reached my 11.7 goal with power to spare on 20170405. If I were willing to burn through another set of rear tires I'm sure 11.6 or better is possible. The full story of this track visit is in
Post #52.
[Street Rubber]
I now believe that 11.7xxx is probably the best I can coax out of this street rubber, once I learn to feather the clutch enough to get my 60 ft time under 2 secs.
[Auto/Custom Launch Control]
I've abandoned all hope of Launch Lontrol (LC) getting me any improvements. Nearly all runs in my previous trips were staged with Custom Launch Control enabled. With the exception of the first 2 runs, this trip was all manual launch. While LC does work much better than the one-size-fits-all 5th Gen LC, it still has inconsistent results. It's not easy to determine what parameter to change (RPM/slip) in order to stick without bogging. Even when you get it just right for one pass, the next one will seldom be the same - maybe the track gets slicker or stickier or the temp drops.
To get good 60 ft times on street rubber the clutch must be feathered. Controlling wheel-slip by varying the timing is apparently what launch control is doing. This is just not responsive enough to handle the changes in torque and grip that the tires encounter, especially during launch. If there is any eLSD action employed with LC, I would expect it to work much better. If it sticks it's at such a low RPM that there's not enough torque. If it slips into higher RPM there's too much torque.
[Manual Launch]
I'm finding it easier to modulate clutch release and throttle input during launch to achieve better traction. It's going to take more seat time to get faster with full manual launch. Even with improved skills, however, I believe I'm approaching maximum street rubber times; even with a good burnout. On this trip my ETs were much more consistent. Average ET was much higher too, even with wheel slip I was getting on the launch and/or shifting to 2nd. My last pass saw temps drop into low 50's F. Even with a good burn-out I had to peddle the throttle in 1st, 2nd, and 3rd.
[Line Lock]
Line Lock should be available outside the Launch Control menu. I cursed the Launch Control menu on every manual lauch (9 of 11) on this trip. It's such a pain in the @$$ to press and hold the Stability Control button for 5 full seconds to disable Performance Traction Management (PTM) mode, turning off all the nannies. If I don't do this the engine bogs badly on manual launch. If someone knows a method to enable Line Lock without doing this, let me know. I felt like a jerk making everyone wait for me to stage while I was disabling the nannies, ever so slowly coasting to the staging gate. Doing a burn-out without line-lock does not sufficiently heat up the tires.
I'd be interested to hear other 6th Gen ZL1 drag strip stories. Except for one other guy on the fast list I'm apparently the only one doing this.
I'm always open to suggestions too, so sound off if you've got an idea that hasn't already been presented in one of the threads below.
