I have one of these jets that I bought partially built. It came set up with BVM T-33 turbine intakes grafted on to the JMP intake openings (surprisingly good fit) so that the previous owner could use a BVM Bypass shroud for a RAM750. I have installed a Ram1000 in the same bypass and it seems a little tight for airflow over the outside of the turbine. I am also using a Tam pipe which slips over the rear of the BVM bypass.

I am experiencing what I would consider an excessive amount of heat on the surface of the tail of the plane. I would describe it as like touching the hood of a black car that has sat in the summer sun all day (very hot). So far there is no visible damage to the fiberglass. It does not seem to have been hot enough to soften up the fiberglass.

What are you other owners of this plane doing to minimize the heat transferred from the pipe to the upper fuselage?

What pipes and bypasses are you using? Especially with a RAM1000 setup?
