non lock torque converter
By its nature you will not transfer as much power as a lock-up. All 1st gens have non-lockup converters. An aftermarket non-lockup makes ALOT of difference and the harder you spin it (more RPM's) the tighter it gets.
They're more reliable because there's no clutches to burn up, but a burned-up lock-up converter becomes a non-lock-up converter...
Lock-up isn't desirable in a lot of car racing applications because it adds sprung weight, and at 7500 RPM and 500 foot pounds of torque it's a lot easier to get a very efficient fluid coupling than at 2700 RPM and 1200 foot pounds of torque.

Its a give and take. In our applications, a lock up would be better. But that involves a transmission swap and some wiring. To some its worth it, to others an aftermarket non-lockup will work wonders!
