Very interesting Ed, so what r we looking 4 in performance wise with this bi metal sleeve and the new crank as well ? Yours original BRB set was placed into Mark engine and i was getting similar lap time with 16 % and 25 % nitro. Hence with the latest crank and sleeve...where would the engine benefit from ?
P.s any more news or test results with crank or sleeve....email me as racing is soon around the corner !!!

Hi Phillip.
As you know our engines are chain of interuptions ( friction, flow restriction etc). By using bi-metall construction we are achiving better friction coeficient on top and bottom part of sleeve ( temperature on top and bottom are different and required different expention rate). Till now we were sacrifising some of the benefts because it wqasn't possible to make sleeve out of 2 different alloys and hopefully now this will be solved.
