Does a lower STR also mean a converter is tighter?
Looking at buying a Yank SS3200 and one of the selling points of this converter is that it is very tight, and designed for 3.15 gears. STR for this converter is 2.1, and I've noticed that the larger the convereter, the higher the STR seems to be. Is a lower stall ratio a result of a tighter converter (down low), the result of not spinning up as high in the rpm band before hitting a one-to-one ratio, or some design parameter in the converter itself?
The basic question: Does a lower STR indicate a converter is fairly tight?
Thanks for any input.

The SS3200 was designed for the C-5 corvette with the use of 3.15 gears and will drive very close to stock as the factory C-5 converter has a low 1.88
STR the step up to The SS3200 will give you that great feel at low speed and will make you when you push the the throttle down.
You have made a very good choice for your car with the mod's you have listed in you posts
The STR is the extra leverage that you get from a dead stop take off
it is most usefull when powerbraking or jack rabbit starts, that is where you will get the max number 2.1 to 2.2

Stall Torque Ratio - the amount the torque converter multiplies the torque from your engine. Hence a 2.1 STR will multiply your engine torque by 2.1.
The looseness or tightness feel of a TC is imparted by the angle of the internal fins which also determins stall speed.
