Title: !/8 Mile To 1/4 Mph
Post by: Billyisgr8 on September 07, 2006, 10:42:18 PM

what does a 89.57 mph in the 1/8 mile convert to for a 1/4 mile mph.

I'm looking forward to an answer...... :rockon:

I wonder if any calculation would be accurate in a turbo, supercharged or nitrous application.

I remember I was racing a 240z turbo (punched out motor) at mission. I was ahead of him till the 3/4 mark of the track. I spanked him in the 1/8 mile. BUT next thing you know it he caught up to me and did a 11.80 or something at 115 or 116mph while I did a 12.1 ish ET.

MPH is mostly a function of Hp & weight. While the gearing certainly has an effect it's much less than you might think. The turbo cars are much faster because they generally have more horsepower. wayne

Quit speculating and just get down here and run the 1/4 mile, your starting to sound like James
