The convertor is a brand new design, not a reworked and comes with a light weight flywheel. It is specifically for the v6 4.0 mustang and sold/made by supernatural performance. One other person I know has one installed, dropped 3 tenths off his et and allowed a 2800 launch. That car is super charged though. 13.4 is my goal on pump gas, I am shooting for lower with a race gas track only custom tune.
I have everything except the hood in my basement now.

I questioned the stall speed as I know from experience that every time you add more power to a car, the stall speed gets pushed higher as the extra power makes the converter "looser" from the extra torque. My converter was rated to stall at 3400-3600 rpm's, but after a tune it went to 3800-4000 rpm's, and now with a JLT II CAI and tune it stalls in the 4200-4400 rpm range. Peak torque on a 4.6L V8 is at 4500 rpm's, so I'm right on target. Peak torque on a 4.0L V6 is 3500 rpm's, so you will be fine even if your stall speed gets pushed up several hundred more rpm's with more mods.
