Re: Car Math. Calculate anything!
Here, this should make up for that:
1/4 mile ET = 1/8 mile ET x 1.5832
1/8 mile ET = 1/4 mile ET / 1.5832
1/4 mile ET = ((Weight / HP)^.333) * 5.825
1/4 mile MPH = ((HP / Weight)^.333) * 234
HP = (Weight / ((ET/5.825)^3))
HP = (((MPH / 234)^3) * Weight)
NOTE: pi/4 = 0.7853982
cylinder volume = pi/4 x bore^2 x stroke
stroke = displacement / (pi/4 x bore^2 x number of cylinders)
compression ratio = (CylVolume + ChamberVolume) / ChamberVolume
cylinder volume = pi/4 x bore^2 x stroke
chamber volume = cylinder volume / compression ratio  1.0
displacement ratio = cylinder volume / chamber volume
amount to mill = (new disp. ratio  old disp. ratio / new disp. ratio x old disp. ratio) x stroke
piston speed in fpm = stroke in inches x rpm / 6
rpm = piston speed in fpm x 6 / stroke in inches
horsepower = rpm x torque / 5252
torque = 5252 x horsepower / rpm
theoretical cfm = rpm x displacement / 3456
volumetric efficiency = actual cfm / theoretical cfm x 100
street carb cfm = rpm x displacement / 3456 x 0.85
racing carb cfm = rpm x displacement / 3456 x 1.1
effective ratio = (old tire diameter / new tire diameter) x original ratio
actual mph = (new tire diameter / old tire diameter) x actual mph
drive wheel torque = flywheel torque x first gear x final drive x 0.85
wheel thrust = drive wheel torque / rolling radius
g = wheel thrust / weight
weight transfer = weight x cg height / wheelbase x g
lateral acceleration = 1.227 x raduis / time^2
lateral weight transfer = weight x cg height / wheel track x g
centrufugal force = weight x g
rpm after shift = ratio shift into / ratio shift from x rpm before shift
driveshaft torque = flywheel torque x transmission ratio
actual mph = 3600 / seconds per mile
speedometer error percent = difference between actual and indicated speed / actual speed x 100
indicated distance = odometer reading at finish  odometer reading at start
odometer error percent = difference between actual and indicated distances / actual distance x 100
mph = (rpm x tire diameter) / (gear ratio x 336)
rpm = (mph x gear ratio x 336) / tire daimeter
gear ratio = (rpm x tire diameter) / (mph x 336)
tire diameter = (mph x gear ratio x 336) / rpm
percent of weight on wheels = weight on wheels / overweight x 100
increased weight on wheels = [ distance of cg from wheels / wheelbase x weight ] + weight
center of gravity behind front wheels = rear wheel weights / overall weight x wheelbase
center of gravity offcenter to heavy side = track / 2  [ weight on light side / overall weight ] x track
cg height = [ level wheelbase x raised wheelbase x added weight on scale / distance raised ] x overall weight
