I took my AEM EMS out last night and did some datalogging and with it I can see what my speed is plotted out over time.

I ran 0-60 in 5.12 seconds and 0-100 in 12.95 seconds.

I don't have a direct way to calculate distance but I probably could with some work but I thought you guys might give me an estimate of what I would do the 1/4 mile in ???????

have you tried using the hp/tq calculations that are posted up somewhere on the ems forum? im trying to rember some high school physics to get ur times but it aint workin

<~~ wadzii from the aem board

Yes, I am getting something like 225 whp and 166 tq using the internal datalogger at 7.5PSI. I'm pretty happy with that and the car is pulling like a MF'r up thru redline which is a real blast. My friend almost **** his pants last night taking a ride with me.

Anyway, the maths calculations do not have a distance calculation in them, only HP and TQ. That is why I am asking for some guesses as to what my 1/4 would be.

My guess is about 13.5 seconds, but I really don't know which is why I am asking.

d = 1/2 * a * t^2

Assumes constant acceleration, use an average of acceleration between your 1st and 2nd measurement to take away the accel advantage of the lower, earlier gears. Probably want to use a 'minor' correction factor and throw in some known #s in order to tune the correction factor.

using the 0-60 and assuming constant aceleration i came up with 12.44

averaging the 0-60 and 0-100 i came up with 13.6..

by doing some more math it looks like the aceleration starts falling off really fast after 60mph..prolly when you hit 3rd ger.. but id guess it to be close to the 13.6 number
