Remember piston speed is and average for your stroke and RPM Your piston velocity and acceleration will change and at some point in the cycle each will be zero Also as your rod stroke ratio changes your max Velocity and acceleration will change but your piston speed will not for the same stroke and RPM Your piston velocity starts at O at TDC it will be at its max Around the point the crank and rod are at 90 degrees which for a 3 25 stroke and 5 7 rod is around 74 degree ATDC Wrist Pin Crankshaft Centerline Offset The crank centerline is moved in the opposite direct as you would move the wrist pin to get the same results In the 2 examples below we are at TDC is the wrist pin offset or is the crank centerline offset In both of the examples below it can be either which is offset 0 CARFOR Performance Software by Stan Weiss World Wide Enterprises 17 CE Compress ion Height Piston Deck Height Rod Block Length Deck Height CRANK lt M Stroke l m x NGL World Wide Enterprises c 18 CARFOR Performance Software by Stan Weiss World Wide Enterprises Piston Travel Rod Angle Major Minor Thrust Thrust World Wide Enterprises c CARFOR Performance Software by Stan Weiss World Wide Enterprises 19 Graph Piston Velocity at various RPMs tux qui ven wr equipe aee quet qe tnm

133. 5004 starting point If you change the Intake centerline or valve lash you have to recalculate your dynamic compression ratio Your Dynamic Compression Ratio DCR can never be higher than your Static Compression Ratio SRC But in a racing engine your DCR is generally much lower than SCR Like the SCR the DCR is fixed when the engine is built But unlike the SCR the DCR can change during the operation of the engine Thing like pushrod flex and timing belt stretch can alter the cam timing events and that will change your DRC For street and street strip motors a DCR in the range of 8 8 5 1 is normal This should work well with pump gas and yet not have any detonation problems use dynamic compression ratio to calculate cranking pressure If have an engine at sea level and than take it up to Denver the DCR does not change Let s say have an engine with 7 6 1 DCR and at 70 degrees no humidity and Barometric Pressure of 29 92 it cranks 186 4 psi Then change locations and have 25 95 Barometric Pressure it will only crank 161 5 psi Dynamic compression is the actual physical compression that takes place after the intake valve closes and this generates the cranking pressure NOTE this is all happening at starter motor RPM s Roughly this is how do it 1 Calculate displacement of one cylinder 2 From CR and displacement of one cylinder 1 above calculate volume above piston at 3 From IVC I calculate piston position and then dynamic
