![]() If you're going to be racing the car, the lock-up converter will give significantly better performance down track. With a Lentech style valve bocy, you can bring in lock-up after shifting to third. At that point you've removed all slip from the converter (1:1 drive ratio), transferring the engine power to the transmission in the most efficient manner. If you've got a loose converter, this can be pretty substantial. My converter shows about 17% slip at 7000rpm, so when I activate lock-up I'm going from 17% to 0% slip. ET and MPH are significantly better (like 3-4mph) than if I don't activate lock-up.
