2,300-2,400 RPM Stall Speed. This is a dual-purpose converter for customers looking for the best of both worlds. With a very hard lean on the performance side, this torque converter can be used in towing light to moderate loads. Anything larger than, say, 10,000 lb. we would definitely want to use something tighter. This converter really shines with a larger turbo or a small compound setup, however it can be used in stock turbo setups to create neck-snapping launches.
