Hi i am just trying to get an idea on what ET you would probably get if u can do 0-100 in like 8 seconds?
sorry a bit weird question im just trying to figure out and average 1/4 mile time for the pannie. If anyone could help me out with some good info thanks is appreciated. cheers Nathan |

my exact 0-100 time is 7.93 now but i can do better than that with my pod stickin out my headlight.

well, using the exact value you gave me for 0-100km/h, your car should do the quarter in 14.79 seconds. As i said earlier though, there are other factors involved that may hinder this time

can someone answer me this: cause it might make things easier for me to get an even better figure, am i correct in saying that a cars accelaration would certainly be reduced once it is past 100km/h? I can only work on averages with the calculations i used above, but the average is taken from 0-100km/h, and i assume that accelaration would decrease somewhat after 100k/hr.

as i've said, taking the car to the track is certainly the answer to getting your cars ET. What i have calculated is very inaccurate because I would require more information about the cars accelaration after 100km/h. The other things is, at the track, off the line, you are probably going to get wheelspin and you'll lose time there. So, the answers I am giving are very theoretical.

yeh your doing well though. i need new rear tyres aswell as fronts are going to be done soon but at the moment im going around a corner or round about normally and the back ends kickin out coz of less traction.

thanks mate. how do you guys get your figures to 100km/h? is it with a timer, or something else? cause even those figures would be inaccurate... Oh well, nothing can ever be 100% accurate, there is always margin for error. |

im using a G Tech which has been proven to be real accurate in the past. its been tested on the track in sum cars etc. and came real close like .2 seconds over i think it was. i've tried using timer but alot harder this wil start as soon as the car starts to move then wil stop when u hit 100.

I am going to put the maths down here for everyone to use, it's very simple.
s = ut + (1/2)a(t^2) where: s = displacement (ie 400m) u = initial velocity ie (0m/s) t = time (in seconds) a = accelaration (m/s/s) (1/2) = half (^2) = to the power of 2 the other equation to work out your accelaration from your time to 100 is: v = u + at where: v = velocity (in m/s) a = acceleration (in m/s/s) and the others have the same meaning as above. so initially you use the second equation to work out your accelaration in m/s/s, and then you plug that into the first equation to calculate time to displace 400m. |

so the G Tech doesnt' give you an approximate 1/4 time? I thought some of them did.

yeh it does but i gotta find sumwhere off the streets that goes for over a 1/4 mile first so i can do that time coz i would b travelling fairly fast at the end of it. it gives u a horse power read out aswell
which is calculated at the wheels which has a couple horses off from the dyno run on a silvia my mates had it in |
