According to the Cookbook, Transport Delay and Transport Time Constant should be significantly increased. As a general rule, I have been increasing most LT header equipped engines 10-20% over stock values (both transport delay and time constant). Don LaSota actually recommends more.
These questions are for anyone who has tested the different values on a dyno or someone who is really up to speed on this subject. I am not.
What is the correlation between the time constant and the transport delay?
For those who have tested different values, what range of increase seems to be best with a Coyote with an NA engine? Or a PD blower?
Are these parameters a linear increase with blower engines as LaSota has suggested with NA engines? Or do PD blower engines require less increase in time value over stock values beginning at the point of boost? ie - a non linear progression?
Are the Cookbook's suggestion of 50% increase on both the delay and the time constant in the ball park?
Can the increase in transport delay and time constant be asymmetrical? ie - multiply transport delay by say 1.5 and time constant by say 1.25?
Thanks for providing some clarity.
