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

weight=agirlik
ET=yaklasik zaman

TORQUE = (5252 * HP) / RPM

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

VE = volumetric efficiency =emdirebildigin hava

VE = 0.78 std motorlarda , 0.85 hi-perf cadde motorlarinda

0.97+ for full yaris motorlarinda

Tire height (inches) = {[(section widşŸ * 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

tire=lastik
radius=cap
gear=disli
ratio=oran
rear=arka
height=yukseklik

CID = Number Of Cylinders * Bore * Bore * Stroke

cylinder=silindir
bore=piston capi(yuva)
stroke=alt olu nokta ust olu nokata arasi fark

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 şŸickness * 0.7854 * Bore * Bore PDV = Piston Deck Volume = Volume of Piston Dish + Volume of Piston Dome

CARBURETOR CFM=

BIGGER IS NOT ALWAYS BETTER

WE MUST KNOW THE THEORETICAL AIR CAPACITY TO DETERMINE THE VOLUMETRIC EFFICIENCY

THEORETICAL CFM = RPM X DISPLACEMENT ǃ· 3456

VOLUMETRIC EFFICIENCY = ACTUAL CFM ǃ· THEORETICAL CFM X 100

STREET CARB. CFM = RPM X DISPLACEMENT ǃ· 3456 X .85 bu cadde makinalari icin karburator hesabi

RACING CARB. CFM = RPM X DISPLACEMENT ǃ· 3456 X 1.10 buda yaris

CAM LIFT vs. GROSS VALVE LIFT

CAM LIFT OR LOBE LIFT X ROCKER RATIO = GROSS VALVE LIFT

THIS LEADS ME TO THE NExT FORMULA TO DETERMINE MY GROSS VALVE LIFT IF I CHANGE MY ROCKER RATIO SUCH AS , INSTALLING 1.6 SBC ROCKERS WITH A COMP. CAMS XTREME ENERGY # XE 268H CAMSHAFT. CURRENT LISTING STATES .477/.480 LI9FT w/1.5 ROCKERS

VALVE LIFT ǃ· ROCKER RATIO = LOBE LIFT [ CAM LIFT ]

LOBE LIFT X ROCKER RATIO = GROSS VALVE LIFT

EXAMPLE: .477 ǃ· 1.5 = .318 [ LOBE LIFT ]

.318 X 1.6 = .5088 [ GROSS VALVE LIFT ]
