I have just got my hands on our first 4 (thats right 4) disc Torque Converter. I will be installing this converter in our shop on Monday or Tuesday. We are using a special stator setup. The stator setup is found in industrial forklifts. The torque multiplication properties of this stator are awesome, this will allow us to lower the stall / tighten up the converter w\o sacrificing any low end acceleration. The converter clutch steels will be of the square design, PRT never uses any with the round tab deisgn as they are prone to wear and rattle. To my knowledge we are the only company in the country that is producing a 4 disc converter. We are putting an unlimited horsepower and torque rating on this converter. We will warranty it to the original owner for up to 5 yrs, if a reman HP / Towing Valve Body is purchased or if the converter is purchased with our Stage III Trans. I will post my initial impressions of this converter Wed. or Thurs.....
