Considering buying a lockup box for trans for drag racing. Which one is best to buy and when is best time to lock the convertor in?

I have had both the BT box and the DHD box. Both worked well. The bt box is more hands free and the dhd box is less failure prone IMO.

Which brand is it and how much? Still wondering about when to lock it up, after it shifts to 2nd or when?



He's got a BT box for a great price.

Hit the lockup as soon as you take off. It will lock when it shifts to 2nd
