stroker_2 Posted June 19, 2009 Report Posted June 19, 2009 (edited) A longer rod will lower the port timings. Using the torqsoft piston position calculator for a rodlength of 110mm, stroke 54mm and an exhaust port opening of 89 deg atdc the piston position is calculated as 29.89 mm from tdc. Now if a longer rod of 115 mm is used the angle calculated for the piston position of 29.89 mm is 89.31 deg atdc. As the exhaust port now opens 0.31 degrees later, the power at lower speeds will be increased. http://www.torqsoft.net/piston-position.html Edited June 19, 2009 by stroker_2 Quote
