As we mentioned before, every racing torque converter built today (even the $8,000.00 billet aluminum lock ups used in Pro Mods) has its designs rooted in an OEM torque converter.
The popular 8" torque converter is based on design from Opel that is more than 30 years old, and the popular 10" 258mm and 265mm billet converters are based on designs used by Cadillac for its Northstar series vehicles.
Using these platforms as a core, we build upgraded component parts that increase strength and modify the torque multiplication and stall speeds.
How do we do that?
