Sifting on time instead of RPM
I have a BBC super comp dragster with a powerglide. Right now the transmission shifting is being controlled on RPM (7400) by my Biondo Mega 450. I would like to figure what time interval I should enter into the box, for a starting point, to allow the shift into second gear when the box is controlling the shift by time. I am not using the throttle stop at this time.
