I run a stock drum with a Turbo Action non LBA VB in my car and have for many years with no issues so far, but I know I need to upgrade to a better drum. I talked to Rick Allison this year about his drums and my VB and he said the drum is definitely needed but the VB is ok. I start my burnout in 1st gear but shift it right away into second. I also have a bolt in sprag and Lofgren blanket. BTW the VB is a forward pattern. Makes me think I need to upgrade the sprag when I change the drum.
