STR and Single/Multi Disk on a TC? What is the STR and the difference between a single/multi disk torque converter? I'm looking at a vigilante 3200 stall, but I dont know what the str and single/multi-disk means. Any help is appreciated!

Search around their site more and you'll find all the info you'd ever need. STR is stall torque ratio, by which the converter "multiplies" the torque. The difference in disks just depends on what your application is. 10.7 @ 100, thats a very odd time for 1/8 or 1/4 mile. Typo? Regardless, a single disk would probably hold you and save you some weight as well.

it's not an 1/8 or a 1/4, it's in the 1000 ft. Arkansas is one of the few states with a 1000ft track. that's the actual time too, 10.7@100.45

Single/Multi disk has nothing to do with STR. All OEM converters are single disk and are usually intended for mileage savings when cruising, not for high performance driving. High performance driving will accelerate the wear on the clutch lining. Multi disk converter are intended for forced induction applications or severe NA applications where you would routinely lock up the TCC (torque converter clutch).
As said, STR is the Stall Torque Ratio. This is the multiplication factor fo the converter, usually experienced in when you hit the accelerator on lower rpms. This is what determines the "looseness" feeling mos tpeople talk about when mentioning stall converters. The high the number the hard it hits, the lower the number the "looser" it feels and it doesn't shock the drivetrain as hard.
adamp's time would be about a 12.9 @ 104 on a standard 1/4 mile track.
BTW, a Vig3200 is the best street/strip converter for someone looking for a good converter, especially first timers.
That was my first converter and I loved it!

Adam......take it from me, go with the Vig3600 if you're looking at vig
whatever you do, go between 3500 and 4000......you should come out this weekend and im sure mike will let you drive his car to see how "loose" it is......he has a Yank PT4200.......so thats about as loose as it gets

1000 ft. track, interesting. I see the time on my timeslips here at Beech Bend but I dont ever pay attention to the 1000 ft. times. I figured that was your altitude. Looks like the joke is on me.
Regardless, if you're worried at all about looseness a Vig3200 would be an awesome converter to begin with. If you're not so worried about it I'd throw a Vig3600 in there.
