rpm will vary depending on traction, which varies on your tires and the track conditions.

To disable active handling just "hold" button down for 5 seconds until you see on the DIC that everything is off .
When i launch my six speed car i get the best times by quickly riding the clutch out , not popping it or sidestepping it . I start @ around 2500 rpm and release it completely within the first 25-30 feet . Shift right at 6000-6100 rpm . In my car it has produced better times to stay in third as i pass the finish line but i am revving about 6400 by then , if i shift into fourth @ 6000 my time suffers a little .
26 pounds of pressure in tires , one light warm up burnout , dont over heat street radials and stay out of the water . you def. dont need that .
Good luck and have fun

With that said . My latest corvette an 05 black six speed has been the exception to the rule . But everyone here allready knows about that . I will just list my times so far .
Stock . apx. 600 miles on car with traction control off but not the active suspension ( did not know about that then )
several runs in the 13.10s one @ 13.03 @ 114 Dissapointed was expecting 12.6s like the magazines and chevrolet said.
few months later added the TQ / module from cartek and the vortex ram air from BPP . on an extremely humid day car ran several 12.8s and a best of 12.72 @ 117 Note : a friend with an 04 that typically turns 12.7 could not do better than 13.1 and felt it was the weather ( not sure about this )
I am now in the process of adding the fan controller , 160 thermostat and Kooks headers and cross pipe high flow cats . Will go back out to the track 6/5 and post my results .
other than the dissapointing time slip i love this car , huge improvements in every way . Traded in an 04 i only had a few months to get it . paid too much and still happy about it . The last crovette drag raced was a ZR-1 that turned 11.93 @ 119 that was last year .

Last run was about 12.7 @ 114 apx. 2.0 60' . I have tried shifting at redline and lost a little . Maybe i will try it again just to be sure . Now that the car has headers and high flow cats it may be appropriate to move up the shift point anyway .
Have you tried shifting at 6000 ? Wondering what your results were .
Expect to go to track again june 5th . If i can i will try some different shift points . At least with the car being a little louder now i may be able to hear the engine .

My best time has been 12.499 at 114.9.
I tried short shifting my C5's and lost time, have not tried it on the C6. Based upon my times, I'd bet money that I would run slower. I'm already faster than GM or the magazines.

third gear for sure , was waiting for it to bang into rev limiter but must have just missed that , one run was 115 mph !. not sure why you call it short shifting doesnt this engine make peak @ 6000 , Or am i wrong about that . anything i can do to get a better time is all i am interested in . will continue to try different shift points next track day , but i am sure redline shifting slowed me down a bit . there may be a more optimal point to shift at bewteen 6000 and the redline , only more track time will tell .

Z51, 3rd at redline is 101 mph.

Even my explanation is a simplification, I realize, and there are other factors involved. I know that on my C5's if I shifted before redline, I always lost time.

The Z51 is pretty close to 15% lower through the first three gears. I have seen different numbers calculated for the base but in the real world on my car it is right about 115 as your reaching redline in third. Er, on a track of course.

will be making less rwtq in the next gear than had you
just left in it in the previous gear. For Z51 cars, the
1-2, 2-3, and 3-4 shifts are optimally done at 6500
rpm.
For a non-Z51 geared car, the 2-3 shift and the 3-4
shifts are optimally done slightly below redline:
2-3: 6470 rpm
3-4: 6360 rpm
(at least by my calculations)
The problem with shifting 3-4 at 6360 rpm is that you
are probably about 60 feet from the end of the 1/4
mile at that rpm so you may as well stay in gear even
though you'd be making more rwtq in in 4th at that
speed.

Pat ,
That makes a lot of sense . I have tried shifting my car at redline and it clearly did not do as well as pulling back to just above 6000rpm. My track is usaully crowded and you dont always get the chance to make a lot of runs , but i will try shifitng around 6300-6400 next time i go in two weeks . any idea ifor how the headers i recently put on the car will effect shift points , clearly more low end torque .
Thanks

is between about 4500 rpm and 6500 rpm because that
is where most of the time is spent in a 1/4 mile pass. If
your headers increase tq more at 4500 rpm than at 6000+
rpm, that might also lower your optimal shift point. On
the other hand, if the tq increase is similar at the two rpm
points, that argues for staying in the lower gear longer
because of the increased tq mult of the lower gear.
Another thing which might affect your optimal shift
pm is something I haven't seen discussed on this forum.
Environmental factors (especially heat) might reduce tq
at higher rpm more so than at lower rpm, which could
affect the optimal shift point. I don't know if this happens
but a thought experiment suggests it could. 4500rpm
needs less total spark advance than 6500 rpm. If the
car's computer retards timing because of temp or bad gas
or any number of things, this might affect the high rpm
tq more than the midrange tq, which could then affect
your optimal shiftpoint.
