my truck is a 6-speed. its my understanding the 6 speed RT's have a different torque converter, while the new 8 speeds use the same tc in all trucks
Yup, well aware
Those R/T 2600 stall TC's have been around since 2009
Although slightly better than the regular 2200 they still have plastic internals (stators)
and the tolerances/clearances are not as good as a custom built unit
Edge or Circle D is still considered a significant upgrade over a stock 2600 stall
I bought my Edge 2800 in 2011 and easily dusted my bud's 09' R/T off the line
Even though he had the lighter truck with 4.10's vs my RCSB 4x4 with 3.55's
(all other mods the same at the time, airaid, magnaflow, BD tuner, 28" DR's)
The Street Edge is used in applications with up to 600+ HP and is limited to 2800-3000 rpm of true stall. A good choice for the performance minded daily driver, or weekend racer. A torque converter built efficient enough to drive in the city without adding unwanted heat. Impeller and turbine are furnace brazed. The lock up is upgraded to the latest "high carbon" friction. Hardened input splines, computer balancing and custom configuration. The O.E. stator is upgraded (replaced), and the cover is upgraded to billet steel.
Andre at Edge can also adjust your stall speed and STR (stall to torque ratio)
based on your mods and what you want to achieve
(as opposed to a once size fits all based on stock HP/TQ)
