Re: 2013 Ford Shelby GT500 First Test
Has the GT500 been run around the ring or are there any plans? I haven't seen tough may have missed if this has been done in the GT500. The quarter mile is great, I've got hundreds and hundreds of passes myself running 12's, 11's, and 10's. For me personally running for a sustained period, with a multitude of conditions and situations, using every ounce of capability built into the platform, will showcase everything this vehicle has to offer.
Just looking for something more than a short 11 second straight line blast to evaluate and compare the GT500 and the ZL1.

And yes the title should be 13 GT500 vs 12 ZL1

Where did the 6mph come from with just a short time improvement? If anything the mph should be the same or come down since horsepower is the same and the short numbers are quicker.

Supposedly, the stock run was with the LC. LC will cut back engine power to keep everything nice. A good driver will always be able to outdrive someone using launch control.
This would explain the trap speed differences. As a matter of fact, the mph on the LC stock run is amazingly similar to what was seen in Atlanta at the media event.

If the Launch Control is good, an expert driver will barely make up anything if you have the same amount of grip in between tests.
In the above example you are increasing grip, so you should be able to apply more power. Seems like a lot of mph to gain from that change, which means either the DR's are a whole lot stickier than the stock tires, or the Launch Control is too obtrusive. Perhaps the truth lies in the middle.

The one thing is the computer never has control of the clutch. An expert driver is going to work the clutch launching. Launch Control never has that option. It can simply pull timing and/or work the brakes.

It's a good bet that stock tires with LC will be significantly slower in trap speed than drag radials without LC.

Speed in the 1/4 is always a better indicator of horsepower than ET, which is why a 6 mph improvement would make me raise my eyebrow a bit as well.

Re: 2013 Ford Shelby GT500 First Test
I was always under the impression that trap speeds are relatively unaffected by traction. ETs, of course. Trap speeds, notsomuch. Unless you're doing a slow rolling, 300' burnout at the start of the run maybe.

Yeah but you're forgetting how LC gets you traction. It cuts power.

Re: 2013 Ford Shelby GT500 First Test
Well yeah, but again, 6 mph worth? Just seems like a lot. The LC is cutting power for a second maybe, maybe up to 60' at most? Probably more like a fraction, just to get the car moving off the launch. And MMFF said in their initial writeup that the LC was so good, it was the first time they've recommended leaving it on. Guess that theory has been quickly dispatched.

Trap speeds are affected by traction after you get to a certain point.
If your 1-2nd and 2nd-3rd shift are going to produce a lot of wheel spin then trap speed is going to suffer.

On stock rubber, yes.
But the comparo is between stock tires with LC on vs drag radials with LC off. I would estimate that LC makes little difference on or off with drag radials.
