Default PDR video at Palm Beach drag strip



the pdr system still amazes me . this is a run where I raced a lightly modified white c7 . he pulls a .184 0-60 to my horrible 2.04 but we run by him on the high side to finish 11.39 z06 to 11.60 c7 .

For whats its worth I am certain z06 will run 10 stock with stock tire . no question . I am certain I will run tens next time out just not sure when that will be .

I ran again and got a 1.969 60' still lots of spinning but turned 11.34 in that run

enjoy

Good job. Yea u had the rpms right when u held at 2500. Then some reason u carried it up to 3500. That blew your launch. I tried many many 0-60 runs and found my best at 2500. Car still spun on the street but i got 3.1 sec times.

Looks like u had a blast

OP: Out of curiosity how accurate was the PDR compared to your time slips?
I see the PDR says 11.70 in the video but I wasn't sure if that was your 11.39 run.

Nice! Thanks for posting the vid... tough to hook but as you said 10s are achievable! C7 Stingray can still haul big time!

Yes i believe you are exactly right . After reviewing some of my other 0-60 runs 2500 rpm have netted 3.0 - 3.1 on the pdr system . This run at 3500 netted 3.7 0-60 on the pdr system . i was being aggressive thinking the track prep would help but not for my runs .

i am confident next time at track this car stock with stock tires will turn tens and thats in florida .

Nicely done, hardhattg.
1-2 shift sounded clean.

I agree, you'll be in the 10's in the near future.

Very cool, nice driving!

I can't believe that with the kind of burnout that you did the car actually hooked at 30MPH to where you could stand on the throttle! Was there any evidence of wheelspin at this speed?

Interesting, so the PDR is off some, but at least in the good way it appears, and by that I mean your actually a little faster then what PDR is saying.

Thanks for posting the video. PDR is very cool even if not completely accurate. Based on your posts, sounds like you're feeling much better about the Z. Great!

The PDR shows 100% throttle from just after launch through trap. Did you use No Lift Shift or does the PDR throttle display not respond that quickly?

I thought that was pretty 'ballsy' pulling up to the starting line between those cones at that speed! Looks like a blast. Was that last week at the super cars event?

I thought that burnout was WAY too short and that it definitely contributed at least a little bit to the traction issues.
Most people warn against heating stock/OEM street tires too much as it makes them 'greasy' and only hurts sixty foot times.
I'm not one of those people.
Yes, John Force burnouts do cost A LOT of money when you're on $500.00+ (each) tires.
And yes, too much burnout can heat up the clutch/trans/coolant/IATs as well but you have to find that balance.
It's worth a shot to attempt it, on one pass at least.
Waiting/idling/heating up all of that time in both the staging lanes, waiting for the previous cars to clear the track and for those guys standing around the tree to move out of the way didn't help either but no real choice there.
Pick a cool night, keep those coolant/IAT temps down, do a longer burnout (without riding the clutch) and the car will go a 10.9 at over 126mph.

I agree with you and have had my best runs after putting some serious heat into my c6z cars tires . icing down the intake and pushing car through staging .

my first c6z I eventually got to 11.19 bone stock , stock tires florida track n the summer . this car is definitely faster in quarter mile the c6z.

This was basically a " fun " event next time we will get serious . !!
