[QUOTE="Charles, post: 1565974, member: 103"] I have run a whole lot of 38R's over the years and never run into this.... until my current 02 as of a few months back when I replaced my 38R due to a nozzle going through the turbine years ago. The new one surges like an animal. This is with the 1.15 housing mind you. It will try to build 30lbs at 1550 to 1600rpm or so while surging hard enough that it would certainly break the shaft if you stayed in it. By 1750 it will finally clean up run a stable 30lbs of boost. I see you have moved on and I'm dragging up a dead topic but found it interesting that you had the same experience. I would be interested in a non-biased report on comparative EGT while towing. [/QUOTE]
