new Torque Converter

[stevesrt8]

Just browsing and caught this post in the vendor area....

Looks interesting if Hal will allow it.





New Performance Torque Coverter

New for the 5.7L and 6.1L LX Bodies and Grand Cherokee SRT-8. We are now a APS Torque Converter Dealer and look what we have helped bring to the market for you. 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+!

Features of the APS Converter:

American Made Ticker Taped Torrington Style Roller Bearings .
Fully Brazed Impeller and Turbine Fins .
Input Splines are Heat Treated Chrome Moly 4130 .
Drive Hub is Heat Treated Chrome Moly 4130 .
Full High Carbon Clutch with Flat Apply Surface for comfortable apply but 300%+ Gripping power over the OE Paper clutch .
Fully Rollerized .
Wider Material then stock .
Thicker High Carbon OD .070 Clutch .should outlast the vehicle.
Anti-Ballooning Measures taken
Stealth Finish for “Completely Stock Appearance”
Upgraded Stator rather then for massive additional torque at launch!
Typically 50~75 + Lb feet torque additional at 0-mph for most applications .
2 year racing warranty.
600+ HP capacity .
Available in 2600 Stall . The 2600 stall will not set a Check Engine Light.

Pricing:
$525.00 Converter
$100.00 Refundable Core Charge
$45.00 Shipping
Your cost after core return $570.00

Sounds promising.... last night MadCharger posted a first impression of the APS converter on the LX forum.

This is likely my next major upgrade.

i saw that, but it looks the same diameter and a 2600 stall is not that high. what is the stock stall? i've been happy with 3000 stall converters in street cars before.

a 3000 stall on a 9 1'2" lock up converter would be fun.

Thanks Steve.

Why haven’t more done this mod….as this member asked on 11/24?

Converter, why not???

same reason i asked the question a week ago. not much out there and personally i think a 2600 stall is too low for this size car with our gearing.

Ok, let me help try to clear up a couple questions that have been raised.

Stock Stall:
The stock converter has a variable stall, as in the actuall stall can change depending on conditions. The materials used inside the factory converter allow it to stall out at different speeds. For the most part, it stalls anywhere between 1800 and 2100 RPM's. This allows for a very comfortable driving experience for the normal everyday drivers.

Higher Stall:
This converter has been designed to stall right at 2600 RPM's everytime. APC had to go through several testing phases and redesigns to get the converter to always stall right at the desired RPM. The results is clearly night and day between this and a factory converter. When you want to nail it, right on the mark as designed, it stalls out at 2600 RPM's. Being as consistant as this was designed is one reason the computer doesn't seem to have a problem with it. Most others who have made higher stall converters are experiencing problems with the computer systems. APC does have another one that they have been testing at 2800 RPM's. As far as we currently know, they have not been having any computer problems with this level, however this is borderline. Anything else higher than the 2800 seems to give the vehicle computer system hell, they don't play well together.

Size:
The APC converters are actually factory housings with reworked insides, so the size has no change. There are billet converters available as well, but these are also aproximately the same size as stock.

We've had this discussion in detail before, and when I challenged the variable stall theory, someone pointed out that it is possible with variable pitch stator blades as used in some older converter technology. I'm fairly certain that we do not have the variable pitch technology in our converters, and therefore the stock unit is a fixed stall (like 99+% of the converters out there). Do not confuse electronically variable transmission shift points with a variable stall speed. They are different (i.e., changing stall speeds does not change shift points).
