Need to know you opinions of streetability and if your happy with it. What are the pros and cons and would it matter thats its a triple disk clutch lock up converter? I have no idea what this means and if I changes the converters charastics. I drive the car 2000K+ miles a year at best and see the track about 6-8 times. The brand I am looking for is a Yanks or precision industries vigilante. My mods listed below with 1.6 rockers and LT4 springs going on soon.

 

I have a 3800 ProTorque lock-up in my car. Also just swapped from an M6 to a CPT Pro Race 700R4. With 4.10 gears in the rear, it revs quickly. The streetability is really pretty good. It is not overly sloshy and on the highway the lock-up clutch only drops the engine speed 200-300 RPM (which means that the converter is highly efficient). I would recommend ProTorque over Vig or Yank (never heard anything bad about ProTorque, and there are mixed reviews about the other 2). Of course ProTorque is the most expensive, but you get what you pay for.

As for the three disk lockup clutch, that is designed to be locked up in high gear at full throttle to reduce losses in the torque converter. Standard single disk lock-up clutches would burn up if you did this, but the three disk triples the apply area, and triples the torque capacity. Unfortunatly this puts a large amount of stress on the input shaft in the transmission since there is more mass from the larger clutch and more torque than the shaft was designed for. I would steer clear of the three disk set up and just get a high efficiency converter.

 

Seeing as your boosted, I would talk to the converter builders and get their opinion on what would work best with your set-up.
