I have a Bandit ARF and a P80/120 CF bypass. BUT, I am installing a 3.5" diameter turbine in it which almost is a P60 size....Can someone who knows any negative/positive affects educate me regarding: take off acceleration, top speed, thrust losses and so on when this combo is used. The pipe pipe will be custom built to any size to optimize the thrust of the turbine. My concern is that the bypass being too large will cause more drag than a properly sized bypass for the 3.25/3.5" turbine....Thank you in advance for your educational comments....
