I'll try and explain my goal and why, and I'm hoping that you can tell me where my thinking is incorrect or help to work up an idea of what you can build.
I'm looking for maximum driveability for a 99% street driven truck. I've been stressing of the poor drivability of this jasper TC for a couple of years now, I've even had them replace it twice because I couldn't believe that they actually designed it to be this loose. It's a 2800 stall with the triple disk lockup. I've measured the output vs. input and get as much as 18% slip before the lockup occurs which I find completely unacceptable. I'm wanting to go the opposite direction, from looser to tighter.
Based on my understanding of torque convertors I think I'm looking for a larger diameter, It's my understanding that this will reduce my torque multiplication factor a little but will increase the overall efficiency. I would like it to be as efficient as possible for towing, driveability as to not heat up from excessive slip, and the stall speed setup so that it will stall in the 2200ish range, just a little more than stock. Can this be done by adjusting the sprag setup without compromising on the efficiency? Reliability, My ultimate goal will be to put about 650hp to the wheels (that's a little ways off) right now I'm only around 420 at the wheels but I want it to hold up so I don't have to worry about it when I do get there. Does that mean getting a multi-disk lockup or would a single would be acceptable because of the larger diameter and higher efficiency that there will be less stress on the disk?
Thanks for your help.
