    Re: Pipe size

    I would contact Tam's to find out. He designs oversize pipes for jets based on turbine size.

    Re: Pipe size

    Well grumania said they wouldn't make me a pipe cause it was to small, so I double checked with Gaspar. Here's what he said....

    Well, I’m using a 85mm on a 160N.



    Pipe diameter depends a lot of the plane, a fast plane with small intakes, like the BVM Bandit need small pipe, while a slow plane with big intakes would need bigger pipe, both with same engine.



    68 is the minimum, as you asked. Ideal would be around 75mm. But 89mm looks too much to me. Probably the problem is that grumania don’t have a intermediate size.

    So I think I'll get Tam to make me a pipe

    Re: Pipe size

    I measured the inlet: 62mm
    Exit was larger at 69mm but could have just been me.
