How do you convert your 1/8 mile time and speed to 1/4 mile time and speed?

you can't acuratly. Your going to have to spring for a 1/4 mile run. There are to many variables. You might have a car that does 13 sec. at 100 mph and a car that does a 13.5 sec. at 110. It is very car dependent and driver dependent

multiplying your 1/8 by 2 would only work if you stayed at a constant speed, which is the total opposite of what you want to do, you want to accelerate =0.

There are 1/8mile to 1/4mile tables out there on the net, you just gotta search for them.

It is pretty darn accurate if you do this:

Multiply by 1.53 to go from 1/8 to 1/4, and divide by 1.53 to go from 1/4 to 1/8

For me, that usually gives a number .2-.3 quicker than what I ran. 1.55 fits my car better.

Yea, sometimes you can juggle that figure around a littl, but from my experience, 1.53 works in most cases. I guess ifyou can run your car at a 1/4 mile track a couple of times so you can record both 1/8 and 1/4 times you can see what variable works best for you.[thumb]
