I just got finished testing my stock OS 91 PS with 30 % coolpower. I tested Bone stock withth the exception of my 3rd needle. Man this thing has the stock shim ( 8 thou ) and the PS Head. Powerfull , Crazy power. I tested the Magnum fuel and I found it to run better with the head shimmed out to 12 thou on the stock Head and on the VH I went to 24 thou . I will note that it ran great with both applications but the cool power is better at 8 thou on the stock just as it comes. The VH setup I feel runs the best on CP @ 16 thou, now this is in GA with thigh humitity and Temps up to 105 with 115 heat index. Nasty but the motor still makes the power. I usually don't fly when it is this hot but I have suffered to help the cause. The needles will be available in the US in a couple of weeks. I will be at Macs this weekend and i have a temp. fix until the needles are here.
