When you spin you get to the same speed in less distance but more time, basically gives you more road to hook and go real fast.

 

why would you think you're at the same speed though? if im racing you from a dig, and you are spinning at the launch while i pulled ahead of you, i am clearly moving faster than you at every distance, which is why i am ahead and still gaining ground. You wouldnt start gaining on me because you launched bad, assuming otherwise perfect shifting and identical cars. you're actually just wasting distance by spinning over X feet instead of hooking and accelerating over the same X feet.

 

this is 100 percent correct

basically look it as you "have more time on the track" to gain speed.

every .1 reduction is about 1mph give or take depending on the car...if you dont believe it go to the track and launch at 2000, 3000, 4000, 5000 and compare your mph with your 60's

 

...

No.

You're not understanding it. You're sacrificing ET for trapspeed.

 

explain to me how spinning over the first 20 feet will mean you are moving faster than one who hooked and is accelerating over those 20 feet.

 

look at it this way, the tires have more time to spin and travel at a higher mph.

for example: these ar egeneric numbers not exacts:

lets say a car takes 14.0 seconds to travel 1/4 mile at 100mph. this is with a 2.0 60ft. now imagine that the tires rotate around 450 complete revolutions the hole 1/4 mile.

now that same car has a 2.5 60ft. the 1/4 mile will be 15.0 at about 105mph. this is because the tire gets to make more revolutions the whole 1/4 mile. - about 480 compete revolutions. (30 more)

the more revolutions a tire gets to make the more speed it will obtain..

 

Uh..... I like Yo-Yo's

hehe.. i get it.

 

this is the problem. This bolded part is not true when spinning.... If what you said were true when spinning, then a stand still burnout would be best way to achieve a higher trap speed

 

Hunter, whether any of us are capable of putting the physics of it in to text for you doesn't matter.

The fact is: When comparing similar cars with the same transmission ratios driven as hard as possible the one with the better 60ft time will usually have a lower trap speed and win while the one that spins more will have the higher trap speed. If you had spent enough time at the track you wouldn't be pestering people about it and would just accept it as fact because you would have seen it enough already.

Also: consider the person spinning usually takes longer to get across the finish line (assuming similar power outputs). Longer time to finish=more time to accelerate=higher trap speed.

D bag

 

it was a joke, obviously

 

The better the 60ft the better the trap speed. It's always worked for my cobalt and mustang for all 300+ passes down the track.

If you spin you waste land for the car to accelerate. You may consider the better 60ft time has a lower trap speed becasue you're bogging or taking it too easy off the line.

Coming out of the hole at idle:

13.35@110.1
2.2 60'

 

...................... poor 60' means better trap. news to me.
if you switch to bigger tires such as a set of slicks and get a better 60' but will trap less, thats the only way the better 60' would mean less mph.thats only b/c of the bigger tire takes less revolutions.
So if you take same car, same tires, same everything @ 105mph with a 2.2 60' would run you say 13.5 but a 2.0 60' would yeild you a 13.1 @ 105
