I plan on ordering a Vigilante torque converter in the next day or two. I'm on the fence between the single disk or multi disk units? I'm told I can lock up the multi disk but not the single. Do you guys see advantages by locking up your converters on Procharged cars? I'll be running a D1SC at full boost in the near future and praying this 4l60 holds up for the season. What kind of stall speeds are you guys running? I was thinking 3600

 

3600---multi disc. you got it. I started out with 3200. but went to 3600. Just call PTC man. great converters. his son drove an ls1 camaro (the owners) and they are all about drag racing.

 

It was my thought that the single will lock up but not at wot and the multi will. I started with a multi 3200 as well but moved up to the 3600 to help my 60 ft. jeff

 

3600 circle d single disk in my 4l80e. Unless you are wanting to go 175mph in od locked then multi disk is not needed.
