I did
have the privilege of seeing Steve Brooks’ rotary installation in his Cozy mkIV.
Looks great. He is using the stock turbo option. Does anybody know if the stock
turbo will hold up for continuous duty? I have heard the bearings and
lubrication is a problem. Maybe I heard wrong?
I sure hope it holds up, or I'm in trouble. The stock
turbo holds up very well in the 2nd gen RX-7, and "continuous duty" is sort of a
relative term. The turbo is always turning, but not at super high
rpms. I'm certainly stressing mine more than it would be in a car, but
it's tough to say how much more. Buying an aftermarket turbo doesn't
guarantee longevity either. Then you have to worry if it will take the
heat of the rotary exhaust. At least we know the stock one
will.
BTW- I'm not trying to sway you either way. There are
certainly better size choices for aircraft use, than the stock
turbo.
