Two C7's duke it out at Drag Strip. VIDEO
 

Auto vs 7 speed at Royal Purple Raceway in Houston. First timers obviously but cool to see them already at the track. Check it out.

:cool: Thanks for the post.

Fresh meat! Lol

Thanks for posting video! :thumbs:

Was the AW the auto

Looks like a ball of fun.

Thanks for posting.

AW kicked ass I bet it was the A6 as it got off without really any wheel spin:rock:

The stick was late off the line...and also spun badly.

For a first timer, that's a really good time he cut in the right lane. They only get quicker from here on out.

Automatics are much more consistent on drag strips...less driver error.

yep

All day

:iagree:

Bet we see some decent runs yet this fall.

The AW was a Z51 and the VY a base model. Wonder if Z51 goodies helped.

So much for a "easy break-in" period ---- Nice!:D

Watched it twice, he (white car) got about a half second better start, just about exactly the time diff.

I don't know if you are a drag racer, but each side of the track has a timer and when the front tires leave the laser the timer starts it does not start at the green light... the first number on the board it the reaction time and when the cars pass the finish line the 12.2 does not include reaction time. The total time from green to finish is near 12.7 but 12.2 from laser to laser.

You can read up more here.
A common misconception of newcomers is that the ET (elapsed time) clock begins when the green starting line bulb is lit. This is a false misunderstanding. In fact, there are two separate time recordings taken on the race track: reaction time and elapse time. The reaction time is the time elapsed from the flash of the green bulb to the motion of the vehicle as it completely leaves the starting line beam. If that seemed a bit too much, let me refresh your memory and elaborate further.

Yeah but wasn't that a heads up race, first to the finish line?

Every Race is first to the finish line. :) If your not first your last Ricky Bobby. The real story is the MPH on each side. The car is the right lane is making big MPH over the Left.

Yeah I know that, lol. Was just wondering how E.t. Came up. :cheers:

You may be correct, I'm not a drag racer and could write a book on what I don't know about it. I was just watching the film and reacting to what I saw. Seemed like the white car had a better time but left 1st by about 1/2 second. But I admit I could be in left field, not my specialty.

Generally more consistent but not always. I'd say my passes are all within .1 back to back to back. 1/8th and 1/4 mph equally similar. T56 w/ a BFG drag radial.

if the guy on the left missed a shift or short shifted he'll kill his trap speeds in a hurry. 115mph isn't monster HP, in fact that seems slow for stock. The left lane was driver error, not lack of HP.

Dave

:iagree:

Traps do not include reaction time, so the time shown was actual time difference through the lights. Physical time from green light would be trap + reaction time.

One could have a quicker time in the quarter, but loose a race due to slow reaction time, conversly win a race with slower time with a quick reaction time.

Manufacturers measure their times strictly on point to point times regardless of reaction times.

A new car requires some seat time, regardless of your experience at the track. There are many variables to think about if you are serious about drag racing. Items like the correct tire pressure, launch RPM, coolant temperature and oil temperature all contribute to a better elapsed time. (and that is the short list)

If you consider that these two runs were rather early in the C7 life cycle, I am sure that we will be seeing 11.8X times in stock trim in the future. :thumbs:

Regardless of whatever problems GM is having with quality issues Corvettes perform very well at the track. :yesnod:

115 mph trap is not slow for a stock car.....maybe on a car that has been modified.

Not too bad by the white car. Would love to take a C7 down the track some day.

almost looked like the a/w front weels left the ground :woohoo:

I disagree. A car w/ nearly 400rwhp should trap better than 115. I'm at 3400# in my C5, have 375 RWHP and trap 120.

Dave

There was a 10 MPH differential. The yellow car owner was new to this, as expected.

Conditions vary from track to track....

In my experience a car that has traction problems usually trap a bit higher. Trap speeds indicate your HP fairly accurately, its been proven time and time again. When I cut a 1.7 60' I usually trap higher than when I cut low 1.6 60' times.
