Has anyone used ATS torque converters???

If so any problems out of them?

Did anyone noticed much of a difference with 60 ft or track times or anything else driveabilty?

I am thinking about changing it up and see what else i can get for this thing before more power!

If your signature is correct you already have a PI converter so I doubt you would notice any difference in performance. It would be a waste of $$$ IMHO.
Now if you had a stock TC then yes it would be an upgrade.

:eek: How in the hell.

I'm making just as much power as you can my Coan Racing converter that I had put in 3 years ago when the tranny was rebuilt is holding up just fine.

Fluids is Motorcraft mercon V no problem there!

I am breaking the sprag on the stator everytime, first it starts to make a cirpping noise then i will not have a stall So about like pulling a house in overdrive out of the hole but once it gets past that spot which is about 25 mph the wheels will break lose and carry the truck sideways about 3 lanes of traffic. :doh:

Im looking to upgrade my trans too. My cousin races a 78' Little Red Express TT Cummins and he has been using a suncoast for the past few years with no problems.

Spragless converters shear the fluid faster. It gets darker faster. Doing fluid changes something to the tune of every 7500 miles...

Used to run a cheap racer x torque convertor (X6tc) for about a year with no issues @ 550hp and 6months @ 650 hp.

Then i figured that i should upgrade to a PI since i got more power and i thought my racer x was a weak link. It hasnt been 2 months and 1000 miles and my PI convertor was making weird noises and it had to be sent back to get made into a spragless. I did cut some 1.5 60fts though!

Also maybe somebody can anwser this question.......Why does a PI torque convertor weigh so dang much???....It weighs 70 plus pounds. A suncoast or similar doesnt weigh they much. It cant be helping power.

My suncoast was one heavy SOB... not sure how much but it suprised me.
