I am curious -
if a turbo doesnt make boost until there is load, how does one load a stick vehicle for drags or pulling?
I would think that an auto would be able to spool faster no matter what the stall, because you are loading the motor from the get go and/or against a t-brake or foot brake?
Sure once underway a stick has a one to one advantage, no slippage unless the clutch is slipping and less hp draw.
However short of the slight hp loss thru friction n slippage, the convertor provides torque multiplication over and above direct imput, and in many cases that is a plus over a stick, especially in a heavy vehicle - makes better 60' usually.
It is also less violent on the drivetrain unless your using a tranny-brake
From experience, with a good convertor, it can and will often outperform a clutch. Thats why there is that Adaptor for a Lenco (brin? brint? brent? or sum such) that adapts a convertor to the stick tranny in pro mods (18-2500hp+)
From what I am seeing and reading, the main issue here is that people are trying to use a transmisison not ever designed for dual duty, meaning street and power runs wether drag or pulling.
From what I read and see, It is the lockup clutches in new style trannies that have issue. Same for the valvebody. Apparently you cant obtain enough line pressue to make em not slip, and still have street manners.
But as we all know, companies build a product that will get the most sales, not necesarily the best use or performance.
