Which stall converter for spray? What are you auto guys using with nitrous? I am running my 4 year old probably 2,000 passes on it, TCI 3600 $450 converter 
Thinking about switching to a VIG 3600 tripple disk. On the dyno it wont lock or hold the torque worth a damn. Just blows right through the converter. Car puts down deccent numbers in the 1/8th 7.30 @ 93 on a 100 shot 1.59 60' but this torque converter is hating me.

A Vig 3600 is a 4000 converter in the real world. A yank SS4000 would be a nice alternative.
A 4000 Vig is a 4400 converter in the real world and is going to be inefficent on the N20.

A car with a signifigant nitrous hit will be blowing way past the torque cuvre of the car. The extra 200-250ftlbs of torque from nitrous will blow right through the 4400 converter on a stock bottom end car shifting at 6800 or so.
Efficiency and application are the keys to converter selection.
On a stock bottom end H/C/N20 car a 4000 converter is right on the money.
A 4400 converter in that same application will 60" worse and trap slower on an identical application on the bottle.

I sure it physically worked but I guarantee it wasnt the most efficient nor the best performing converter for that application.
