It would, but they are pretty pricey. I'm sure there are some on this site that have done that and they will chime in.

 

yes, it would make a difference. it would be getting a lot more of your engines HP to the rear wheels. if you can afford it, go for it.

 

losses in throught the stock tranny are among the worst in the industry, about a 28% HP loss from engine to rear wheels. Nissan and Toyotas by comparison are around 16%...

 

A new converter won't change the HP loss. This is coming from the transmission itself and the axle.

 

That's not what APS claims....the say that there's 14% loss just in the TC itself and their TC reduces this loss by 6%. http://www.apsprecision.com/TQConverter.html How much of that is true I dunno..

 

When the converter is locked, there is 0% loss. It depends if you are talking about fuel efficiency power losses or WOT power losses. An aftermarket unit will likely put more power to the ground that the stock unit, but there are grey areas to make the statistics favorable for anybody.

 

Picking a nit; there is "0%" slip when the converter is locked, but there is still loss in just moving the mass of the converter and fluid. However, changing to a different converter wouldn't change the loss due to mass by much/any, although there could easily be performance gains when not locked.
