The question of how fast the turbo spins in our 6.5td came up in conversation and so far we have not been able to get an answer, so I was hopeing that someone has done all the work of finding this totaly useless info and would be willing to share with those of us too lazy to do the reserch for ourselfs.
Please no guesses, We have enough of our own.
Thanks

All you'll get is a guess. Here's mine 10 psi boost at 2200 rpm = 60,000 rpm turbine speed, 18+ psi boost =100,000+rpm turbine.

Warner-Ihi says 80,000 RPM as max for stock boost.
