What we are discussing isn't a traction issue, it is a launch issue. An AWD launch gets you out of the hole without getting you going as fast as you would be if you came out of the hole (with the same 60') without an actual launch. i have no proof but i have two valid situations i have encountered. First is my friends GSX best is a 31.1 @ 101 yet from a roll he has pulled away from me and i have trapped as high as 104. second is my other friends WRX ran 13.8 @95 however from a roll i do no walk away from him like i would an average car that traps 95 mph. I have raced people that trap at that speed and he is def faster than them.

 

You just can't compare different cars like that. They have different HP/TQ curves at different rpm's than you. So they will pull better at different speeds than you will.

When talking about better 60' times getting you better traps speeds, it has to be compared on the same car. I still stand my the fact that a better 60' time means higher traps.

There are things such as driver error that could make it not work that way though.

oops typo, but you get the idea!

 

Lower 60 ft usually results in lower traps... Not gonna go into physics that would take the whole page. Heres a simple example...

Say we have 2 cars:

One has a running start and retains a constant speed of 60 mph thoughout the 1/4 mile... 60 mph = 1 mile per minute. So the 1/4 mile would take 1/4 of a minute or 15 seconds...

At 60 mph to travel 60 ft it would take 0.67 seconds.

So to simplify the car with a running start trips the light and runs a 60 ft time of 0.67 seconds ans since his speed is constant he would trap 15.00@60 mph with a 0.67 60 ft.

Likewise an average 15 second car with a 2.00 60 ft from a standing start would trap somewhere around 85 mph.

With a good launch you are INITALLY covering more distance faster thus by the time the 1/4 mile ends you are at a lower speed.

Likewise say car A traps at 14.00@101 and Car B traps at 13.00@101.

If we said race for 14 seconds regardless of distance:

Car A would be at 101 mph

Car B would be at 101 mph PLUS the additional speed he picked up during that 1 extra second...

 

it shows if you cover more distance initally with superior traction or in the example a running start you get there sooner and thus have less time to accelerate to higher speeds.
