I’ve
made a few flights now with the new turbo and finally have the engine
re-tuned, so it is running great.
The down side of the new turbo is, that my cooling, which was a bit
marginal is worse with the new turbo.
I did
plan on making some inlet adjustments, but finally decided to just go with a
customer built aluminum radiator.
I found a company here in NC that makes them to order, and it should
arrive tomorrow. It will also
have the aluminum shroud with it to mount a cooling fan, which I did not have
before either. With the pusher,
anything over about 10 minutes of ground operation would have temperatures
over 180 before the takeoff run.
I also
had ¼” NPT fittings put right next to the AN16 inlet and outlet, Since I already have a sensor on the
water pump outlet, I’ll use the inlet fitting for a limit switch to operate
the fan. I’ll also put in a
switch on the instrument panel to operate it manually as well.
In the
next couple of weeks, I’ll remove the old evaporator cores and plenum, build
mounting brackets for the new radiator, and build a new inlet plenum to the
radiator. I had them put a ½”
flange around the perimeter of the core on the inlet side for easy attachment
of the plenum to the radiator.
