Good 60ft + shit MPH = good ET??? WHY?

This ones for the String fans, lol.

So in general, as your 60" time gets better, this is increasing your acceleration. Hence your total time will go down with your mph.

Acceleration:
a = (vf - vo)/t

a - acceleration
vf - final velocity
vo - original velocity
t - time

So for the drag strip:

A (the lower your 60ft time the larger this number) = mph/et

dont get it..

if i accelerate quicker wouldn't my top speed also be higher.. and not lower?

that unless my acceleration was determined from an initial speed at the 60ft time and not ZERO

lol yeah, doesn't make sense now that i think about it, but the formula does show that if your acceleration increases how the other too are affected.

100mph / 13.5 ET = 7.4
98mph / 13.0 ET = 7.5 (better 60 foot)

The shitter my 60ft the better my MPH...

Does it sound weird.. or am i driving strangly..

I have notice this on other peoples runs too.

should have just stayed on the track...
kinda addictive

Hmmmz..
i tend to think of it like logically....
quicker 60ft = end of line sooner... therefore car dont have to accelerate that much to reach the end...
60ft (time it takes from start to the end of the first 18m)...

yeah.. i reckon if you get a crappy launch, car takes longer to reach the end. therefore you have more time to gain speed..

blitz my way of explanation was kinda right lol.

I just didn't involve the equations and maths into it.

Just get your 60ft down then worry about the rest later.

**barefootbonzai** · 13-10-2006 04:06 PM

now if you did maths b at school and rearranged the equation. we get something useful.

ET = mph/A(lower 60ft = bigger A).

man being technical is gay, just wanna make String proud, ahahahahahahahah

hqhah lol at the tech info.. damn e-mechanics haha

I know just being a tyre kicker...

not sure if i should stay on 18psi and get a better 60" or increase it and practice on 20psi and get a high MPH..
