Posi lock-up clutch:
Yank Converters has made a breakthrough with the Posi lock-up clutch. By placing proprietary bearings between the lock-up clutch and the housing, while utilizing the highest grade carbon ceramic or kevlar linings, the converter can actually lock-up under the high torque load of a power adder like nitrous oxide or a blower! This positive lock-up action takes place when the engine torque exceeds 475 lb. ft. This will give the racer torque to the tires, close to that of a manual transmission. This is a Yank exclusive!
Pro Yank Series Converters:
Power adders place special demands on converters. It is important for a converter to have adequate "holding power" while at the same time, placing the motor in a higher power band through increased stall. The Pro Yank converters give you the best of both! First, each Pro Yank is custom built around "your" power adder. The stall speeds are rated for use with power adders and will therefore, be right where you need it to be. Next, the Posi lock-up clutch will bring efficiency close to 100% by locking-up under load. Finally, the clutch materials are built to take the higher demands of running on the "juice". The Pro Yank Extremes use the exotic Kevlar linings.

Does this mean that the convertor is going to lock by itself? Pretty cool if you ask me. This one goes for $995 (the 3400 or 3600 Extreme), and is designed for power-adder cars (nitrous, blower, turbo).
Are these convertors for 200-4R's? Anyone use one?
