LOL and you are an auto or manual? 1/8th Mile ET and MPH Calculator: Wallace Racing BACK to Calculators. Alternately, hooking the crap out of the car might show a slightly lower mph, but a nice improvement in 1/4 time. wake the fuck up. Will achieving a faster 1/8 mile give you a higher overall mph in the 1/4? Try our 1/8 mile calculator that provides an accurate elapsed time and speed based on the horsepower and weight of the vehicle. Like at least 8.5:thumbsup: so today just out playing with stock air pressure and using the in-car timer, i launched at 3750 rpms and some-what short shifted and ran a 8.7 (note, this was with the in car timer so not sure how accurate it is). Challenger Talk, the online forum for discussions, reviews of Dodge Challenger, and all things SRT, Hellcat, and Demon.

Rear Wheel HP is assuming a 10% drive train loss. The 1/8 Mile to 1/4 Mile conversion table helps you to calculate the approximate time taken by a vehicle to travel in a quarter mile track based on elapsed time taken by the same vehicle to reach eighth mile (201.168 meter or 0.125 mile… These equations are for recreation only. distance = rate x time. This is assuming horsepower is constant because for turbo cars at WOT @ 3500 - 4000 rpms are at full boost, therefore at full horsepower. You will need to convert the metrics to the same time and distance units, e.g. On oem street tires with 24 lbs air and bone stock 8.6 to 8.9 depending on hooking the tires up. Almost bald? This 1/8 Mile to 1/4 Mile conversion calculator is used to calculate the approximate time taken by a vehicle to run in a quarter mile (402.336 meter or 0.25 mile) track based on elapsed time taken by the same vehicle to reach eighth mile (201.168 meter or 0.125 mile) track.

In order to use the above speed, distance & time calculator, or do such math on your own, you will need to know two out of three metrics: speed, distance, time. So 1/8 mile time and speed will give you a more accurate reading. distance = speed x time. Theres a few tricks we have tried on the bone stock jeeps and they all seen to work. Any thing is possible depending on the cars race wt and DA. i have been told to not really launch but take off just like i would from a red light and the wot, and i have been told to drop clutch around 3500-4000 rpms. miles, kilometers, meters, yards, feet, and hours, minutes or seconds. BTW, that second half charge is the beauty of a turbo car, Okay, traction [at the head of the track] doesnt have much to do for 1/4 mile mph [at the end], but 1/8 mile #s [half way down the track] do.
