IS this new TC better than DTT? OR at least in theory (since it hasnt been tested in the real world yet. )
Here's the deal. You've got two (and more) different companies with two different philosiphies about torque converters.
The conventional way to think about a torque converter is to make the converter a "Low Stall" and then make a Strong clutch that has enough holding power to not slip,, even at very low RPM where Diesel's make a ton of torque,
Bill K's way of thinking about a Torque Converter is a little different, and yet the same. He makes his Torque converters "Low Stall" and rates them in %,, the 91% transfers all but 9% of the power. goes to the ground 100% of the time, and when in lockup 100% goes to the transmission.
The difference between Bill's Converters and other converters that use lockup for the majority of power transfer is longevity.
The shock loads that are put upon the transmission when the torque converter is locked up, and the transmission shifts to the next gear is to say "Large". The idea is simple enough, SOMETHING HAS TO GIVE, either the engine lugs down to the next gear, the tires slip, something slips in your transmission, or something breaks.
Bill's philosophy is simple, and yet unique to the transmission industry.
He makes his TC's as tight as possible (91% is extremely tight) and uses lock-up only for cruising and medium acceleration.
At WOT he makes his TC's un-lock. His philosophy,, SOMETHING HAS TO GIVE, when the transmission decides to shift and the Torque converter is NOT LOCKED-UP the torque converter's fluid coupling is what gives!! You don't have to worry about WOT shifts destroying any bands, clutches, input shafts, drive shafts, or anything else( although Stefan K. tells me that his tires will still spin into oblivion on the 1-2 shift @ WOT). His converters offer a "Buffer" so when the transmission shifts the thing that gives is the TC, not something that will cost you big $$$$ to fix, or leave you stranded somewhere.
Buy what you want, or buy what you need.
I drive a 5-speed manual transmission, and I still like DTT because of their outstanding Customer service and the "Tell it to you straight and true" philosophy when buying, fixing, or selling parts.
Anybody set me straight on any of the opinions and thoughts I have in this message, otherwise I am assuming I'm correct from what I have heard From Bill K. at the Texas Rally 2001.

P. S. 91% of 500HP is 455HP.
