I'm curious how you shop for a toque converter what things you look at to decide how good it is and how these things effect the performance of the car, I see mentions of high rpm toque converters and have no idea what they are talking about.

 

My best suggestion is to have all your vehicle info and go to a reputable company and ask for their recommendation. You have probably heard of diameter and stall. The most important thing to know is the torque the engine produces and how it makes it's way to the ground. Transmission ratio, rear gear ratio and tire size all matter.
If you look at cam manufacturers rpm recommendations that say 2000 and up it would be sluggish until you got to that engine speed and you would feel it start to pull. With a manual clutch you could overcome this with your foot, an automatic would need a higher stall (rpm) converter to do the same. The same converter will react differently behind engines with different torque outputs. I hope this helps.

 

x2. TQ selection seems to be a "black art"! A bit harder than cam selection. Cam, rear gear, TQ selection, and goal of the car, are all inter-related. Were it me, I would try to involve the TQ techs at the beginning of my build! Tell them what you are trying to accomplish.

 

Have all that data and call someone like Paul Forte with Turbo Action...or Rick Alison with A&A transmission is another good guy...he set me up with a 9 1/2" converter for my 440...it screams
