Not a big difference but... I also have not flown the new KC with anything but a P-120 and now the Titan. It is definetly more power than the 120. One of my standard tests is a vertical eight, last weekend I did one then immediately pulled through a second one right after. Plenty of power.

FWIW I ran a MK I P-160 for 230 flights without a problem at 125K when I truned it up to 128 it lasted about 5 flights. When I first got a MK II i kept it at 125 and had a lot of trouble with the turbine wheel rubbing the EGV (seemed to be the common problem) then also had a few fuel manifolds fail. I am particularily hard on engines I fly a lot. From what Bob tells me at 123K the Titan should be just as reliable as my P-120s one had 400+ flights the other 500, before I had new bearings put in them. Time will tell but it seems very smooth and is definetly running a good bit cooler than the earlier P-160s.
