Len's opinion was, it was the power drain to make the shift so hard that it spins the tires that was costing the e.t., not the wheelspin, itself. I'm sure you're right though; the wheelspin couldn't have been doing anything good for the elapsed time. :angry7:

He (Len) would back the main line pressure off until it began to have a really soft shift, and then increase it in small steps until it was just satisfactory, but not harsh.
That minimized the power it took to make a sufficient amount of main-line pressure for efficient operation.

Len has won 3 Divisonal Chanpionship in Super Stock (NHRA's Div. VII), was runner-up for two others, and I have won zero, so when he talks, I listen.... LOL!
