EGT temps are monitored by an ECU on board. Guessing 600 degrees or
more. The problem with this install is not so much the tailpipe
design but the inlet design. Where did they hack a inlet for this
turbine? The tank is right in front of the turbine inlet so the
efficiency of this one is probably pretty lousy but enough to get it
up in the air. Most of the turbines are 10 to 17lbs thrust which is
more than enough for a 4 or 5meter salto.
