whats a safe # to do a manual launch at without the upgraded input shaft. Im trying to figure out how to launch this truck in 3rd gear and it working pretty good but im having a hard time controlling this turbo when it starts to light. sofar ive been launching at about 30#. got it upto 40#'s once and am pretty sure that too much. any help would be appreciated because i dont feel like pulling the trans back out

 

you shouldn't break it doing launches, pullers have been launching in big gears for years with alot more hp than you have, it is a sudden shock 99% of the time that wipes them out
