Conversion 1 Liter = 61.02 Cubic Inches

HorsePower = TORQUE * RPM / 5252

HorsePower from MPH (1/4 mi.) = (.00426 * MPH)^3 * WEIGHT

HorsePower from MPH (1/4 mi.) = WEIGHT * (MPH/234)^3

HorsePower from ET (1/4 mi.) = WEIGHT * (5.825/ET)^3

ET from HorsePower (1/4 mi.) = (WEIGHT / HP)^.333 * 5.825

TORQUE = (5252 * HP) / RPM

CFM = (CID/2)*(RPM/1728)*VE

VE = volumetric efficiency
VE is approximately equal to 0.78 for stock engines, 0.85 for hi-perf street engine 
and approx. equal to 0.97+ for full race engines.
This gives rather low values for CFM but is probably all you really need.

Tire height (inches) = {[(section width * profile) / 2540] + (wheel diameter / 2)} * 2

60 foot time from ET = (.12 * 1/4 mile et) + .17

MPH = Tire Radius / 168 * RPM / Trans Gear * Rear Gear

RPM = 168 * Trans Gear * Rear Gear * MPH / Tire Radius

GEAR RATIO = Tire Radius * RPM / 168 / MPH

Tire Radius = 168 * MPH * Trans Gear * Rear Gear / RPM

CID = Number Of Cylinders * Bore * Bore * Stroke

Volumetric Efficiency = Actual Engine Air Intake (CFM) / CID

Compression Ratio = Cyl. Volume @ BDC / Cyl. Volume @ TDC = 1 + (Swept Volume / Volume @ TDC) = 1 + (0.7854 * Bore * Bore * Stroke) / (CCV + HGV / PDV)

CCV = Combustion Chamber Volume (in inches) = CC's / 16.4 HGV = Head Gasket Volume (in inches) = Compressed thickness * 0.7854 * Bore * Bore PDV = Piston Deck Volume = Volume of Piston Dish + Volume of Piston Dome

HorsePower = Atmos. Press. * CR * VE * CID * RPM / 5252 / 150.8
