I read the posts about the aftermarket converters...any one have any comparison numbers? Seems like a great thing to do, I was just curious if anyone monitored the difference.

 

Your question is difficult to answer because there are several factors that can affect how a TC operates. Just like in the MT you can customize pulleys, flyweights, etc to modify how you want it to perform in given situations. With the exception of the valvebody, the whole TC is designed as a unit. Stall speed is the most common design change on a TC. Generally, higher stall speeds will put you in the power band more quickly buy also makes the TC more jerky. The next most common thing is torque multiplication. The higher the setting the more power and acceleration you get at the cost of velocity and MPG. There is also cooling, lock-up, etc.

Determine how you want your car to perform first then ask how the changes are compared to the stock TC.

 

A high stall does not really make you gain hp. It helps you at the track helping you get into the powerband faster.

 

That is what I said.

 

You can have the same stall speed with a greater STR: stall-torque-ratio and put more power to the ground.

 

Yup, you can adjust torque multiplication to adjust how much power gets transferred to the ground.
