I've heard that APS precision offers a torque converter that is much more efficient than stock ones that suck away our rwhp. Anyone know anything about this converter or others? It's not supposed to be a high stall converter, just more efficient.

Some have the APS torque converter, and others are using the EDGE torque converter, and I have not read any bad press on either. Use the Find feature on the top of the page and type in torque converters (may have to type in APS, or EDGE) Maybe that will help answer your questions.

The APS Torque Converter is very streetable as it relies on a different impeller to not just spacing the members further apart to get additional stall like so many rely on. We also use a Hardened Input Shaft Spline Insert, upgraded friction from paper (OEM) to Kevlar or Solid Carbon-Fiber depending on stall, as well as machine the slight taper off the apply surface for a firmer lock up...resulting in increased top end efficiency. We also increase torque multiplication over the stock unit, meaning we multiply the amount of Torque the unit will put to the back tires delivering EXCITING performance. This is done by using a higher stall stator and a negative raked impeller...these are not just a simple, modified, factory converter with loose tolerances to give you a higher stall effect.

These factors all add up to give you the APS EDGE! Getting the EDGE in performance while maintaining efficiency for fuel economy and peppy around town driving. We increase the efficiency of the torque converter over the stock unit by a full 6% (stock rating is approximately 14% parasitic loss just from the converter). This means that you don't get that "spongy" feeling under light acceleration found in other high-stall converters. Our converters can easily handle horsepower ratings of 600+!

Yes, you read it right. APS now has the ONLY aftermarket performance torque converter for the 5.7L "Hemi" trucks. It offers much closer tolerances than factory (very sloppy) and a 200rpm higher stall as well. With the closer tolerances, you get more power to the rear wheels which, in conjunction with the slightly higher stall, equates to quicker acceleration and faster ET's at the track. Again, we are the ONLY ones who offer this converter. The stators we use are all brand-new custom manufactured, not modified factory pieces. This brings the efficiency factory from the factory 82% to 93%. This can allow us to guarantee you a minimum 25-30 rear-wheel HP increase.

This is from their site.

Now then. we all know that these help but why does it never show on a dyno!

Now that's the money question!

I agree! it would be my next mod if I could get an answer to that question.
