Formula to convert 1/8 mile time to 1/4: Where is it? Accurate?
Any of you guys know about that 1/8 to 1/4 conversion table? I remember seeing them a while ago, but Yahoo.com isn't giving me anything useful.
Also are they accurate? It seems my car has some stones going up to the 1/8 mile, and then has problems after that. I'm not sure if it's because of the 700r4's gear ratios, or if something else is wrong. So, I'd like to use that formula/chart to see what my 1/4 mile would be, and see how close it comes to what it actually is. Make sense?
Thanks!

Great, thanks, that's just what I was looking for! And yes checking out my slips, it does seem to be accurate.. seems I could be doing 2-3 tenths better on some runs, but the #'s are close.
Thanks again!
