Why is it not a good idea? I know there's Bren a few people on here to do it and pulled off some much better mph's...circle d is who I'm going with, I need to lock it up for the mile runs

MPH doesn't win drag races and most people that do have WOT lockable torque converters don't see any ET benefit to locking them so they just don't. Lockup prevents the converter from doing what it does best, torque multiplication and shift extension and it's USUALLY only there to give better gas mileage and prevent heat buildup in most converters and it's going to be very rare that you find a manufacturer that would warranty any type of converter doing WOT lockups at 1000+ rwhp because of the wear and tear on the lockup clutch. That being said in the mile runs maybe a manufacturer would spec a WOT lockup converter for something like to reduce heat buildup, or they might not that would be a much better question for the converter builder as they are the expert.
