OK we are talking about a pure stock C6 Z06, OEM tires(Goodyear EMT). I am getting closer to the sweet spot.

60' 1.95 sec
1/8 7.61 sec
1/8 98.74 mph
1/4 11.60 sec
1/4 121.72 mph

Launch 2500 rpm... A quick full release of the clutch.
Rpm drop to about 2000 rpm(Bog) Full throttle.(no wheel hop)
1st to 2nd shift 6900 rpm (58 mph)
2nd to 3ed shift 6900 rpm (88 mph)
Both shifts resulted in a drop to 5200 rpm.
Crossed the line a fraction of sec before hitting rev limiter(lost 3 mph)

I need to have car dyno'ed to see what HP & TQ curve is.
I may need to adj shift points.
I will try shifting to 4th to see if it gains or loses.
A 3000 rpm launch may get me down to a 1.8 60' time.

11.6 on run flats

outstanding and no wheel hop.i guess its the heat getting into the tires.what psi on the rear tires

 

[METERSF]

YOUR NUMBERS LOOK REAL GOOD. AND GOOD ADVICE TOO:thumbsup: KEEP UP POSTED

AT this time I am running 28 psi in the rear. When I find a good solid launch rpm then I start changeing other factors. I have been trying to change to many thing at a time and screwing my self up. Back to basics

It was 80 deg's today 30 deg's hotter than the last time we were out so less HP and less tire slip.

Very good numbers, you are on the right way!
Don't do more than 2500 rpm launches on stock tires. Do shift to 4th, it helps. [per Ranger and IMHO].
Try shifting at 7000 rpm... I know is awfully close to the rev limiter (7100 rpm) and it is hard to hit it precisely.

We get enough people driving these things and we may learn to drive them.

I drove my uncles Z yesterday with a few bolt ons, its putting down 472hp. Wheel spin was heavy even with my 2300 launch, I believe that is what it was I went by feel trying to concentrate on the tree. I had to feather it for the first 15 feet or so resulting in an [email protected] there is so much more in this car its not even funny. This was the 2nd time I ever drove it so I'm not too disappointed. D/R's will be on next time out so expect low 11's or if we are lucky a 10.99

I was shifting into 4th maybe about 50 feet before the finish line at 7000rpm

I forgot to add that all runs were done in Competition Mode, T/C off would've been a nightmare.

iburke, your 11.6 run was done at a 1/4 mile track and was not recorded on a G-Tech correct? Just for clarification thanks.

This run was made with a DashHawk which was dead on with the 12.2 run I made at the track last week. Will hopefully get to the track next week and have a time slip to show the nay sayers...:thumbsup:

Oh ok cool, I wish my cousin would of brought his G-Tech yesterday when I went to the track to compare it with the 20 odd runs that I made.

Those meters are very accurate, I was not doubting your times, the car has the potential:thumbsup:

Good luck next week at the track:cheers:

COOL VIDEO! THE Z IS ONLY BUT HALF THE PRICE OF THAT BENZ... IF THAT. GOOD KILL:thumbsup:

The DashHawh gives you a graphical out put and you can see the fluctuations is the rpm and speed when you go into wheel hop. As it works directly off the car like a data gathering unit, you get exact read out of rpm while shifting and speed loss when hitting the rev limiters. Its a great tool. Some day I will learn how to use its 120 or 30 some outputs.

I also have a G-Tech it is great on the track as it can capture lap after lap of acceleration, breaking, and lateral turn G forces. that you can isolate to a time and turn. But it uses the alternator signature for rpm so the accuracy depends on how close you can get your rpms and how level you can keep the accelerometers in it.
