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

ET = Elapsed Time
HP = Horse Power pi = 3.1416 fpm = feet per minute rpm = revolutions per minute cfm = cubic feet per minute mph = miles per hour g = the force of gravity cg = center of gravity Anything else?

That looks amazing. I don't even care if there's a subscription if it's a decent website like that.
