Turboprop smoke injectors
I'm getting ready to install smoke on a Wren turboprop, I'm trying to find out how to install the smoke injector. Do you just drill a hole into the exhaust stack an insert the standard type nozzle or install some kind of threaded fitting.

RE: Turboprop smoke injectors
Roger at Wren did mine before I got the engine. He put two (looks like about 2.5mm) SS pipes into the rear of the exhaust stacks about 2" away from the centre. I have not used it yet so I don't know how effective it is. The two pipes go back to a brass "T" piece then back to the pump.

RE: Turboprop smoke injectors
I installed one injector as close to the center as possible and we adjusted the direction of the oil spray until we got even smoke from both exhaust stacks.
here is a video of the first flight with the smoke installed after the flight we adjusted the injector.
