Is locking out the converter harmful in a mid to low 11 sec car?
Is it ok to do in 3rd only?
I've heard 2mph and 2 tenths but if it's harmful I don't want to try it as I'am not made of money!
It depends whether the convertor was built to take the punishment of locking up or not. If it is a single disk Vigilante then no, it should not be locked @ WOT. If it is a multi-disk, then yes, go ahead and lock it up @ WOT.
