I'm hoping to get a response from the man himself on this one. I have been researching your topic board on the tranny 's all morning trying to figure out how to choose the right torque convertor for my application. A little more insight would be greatly appreciated on the manner in how they operate. I have somewhat of an understanding, but the tech from someone who really knows these units throughout would greatly clarify this for me. I'm planning on having the tranny done to a stage 4, but don't know how to choose a TC. I am currently running a hot tune, and I am in the process of procuring a TT kit in the future after the tranny gets done. Thanks again.:)

I responded to this thread and it disappeared.:confused:
I'll try again.
For the power you have planned for your truck you will want a converter that is on the tight side and does not multiply too much tq. The LBZ and LLM's make a lot of power plus the fact that you are thinking of TT's a converter with a higher stall will just let your power go out the exhaust and not to the ground.
You want a converter that is loose enough to get out of the hole comfortably and then it needs to start coupling ( efficient ) right away. The tq multiplication should be at a minimum because the engine has enough power and the turbo needs to load up, which it can't do with a loose converter.
The SC 1054 would be a great converter for you and there is a new Precision that I'm testing on a couple of high powered sled pullers.
