HI all, I go about getting the correct CG on most of my jets a bit different than most builders, buy placing the important components where whey are most serviceable, and then moving the turbine . Example is my Futura, which the turbine was moved 2'' forward, and my T-33, about 1.5'' forward.It helps that I make my own Pipes.

PS. i would not hesitate to remove the restrictive air intakes.
