If you're out for dyno bragging rights, yes...locking the converter will make more RWHP. On the other hand, locking the converter in the quarter mile will usually slow the car down, because you lose too much RPM.
Think of it like this...All torque converters slip (stall) to a certain RPM. This is why the car can sit still at a stop light. When the converter spins t a certain RPM it completes the "fluid coupling". All non lock-up converters still have a certain amount of slip, even at full RPMs. Lock-up esentially locks the converter 1:1, which eliminates all slip. You're locking the transmission input shaft of the transmission to the converter front, which is bolted to the flexplate.
This is why you make more RWHP with the converter locked...Because you're now transferring ALL the engines HP through the transmission, because you're not losing any due to slip.
