We are getting ready to test some of the components
 of a turbo compound engine. What we plan to do
 is install a gear box on a turbo charger mounted
 on an engine and connect the output of the gear box
 to a generator to act as a turbo charger dyno if
 you will. We want to make sure the gear box works.
 We will also instrument the turbo charger
 for TIT and RPM.

 The air output of the compressor will
 be connected to a valve to simulate the intake
 system. In other words the engine will not
 be turbo charged. We are merely using a normally
 aspirated engine to drive the turbo charger.

 This is done to prevent a turbo charger
 turbine or bearing failure from generating scrap
 aluminum that will find its way into the engine.
 We don't want to be overhauling the engine
 every time a turbo charger fails.

 My problem is: what do I use for a generator
 that will handle 50 HP or 37 KW.
 Also what do I use for a load.
 I could use 37 one KW electric room heaters.

 Anybody have any ideas?

Hi Paul

I would suggest you test with an electric turbo compound unit from Bowman
first.
Fast rotating generators are naturally smaller. See
http://www.bowmanpower.co.uk/power_generators.php
Then you can also use their electronics that is well adapted.

Then if you need compact electric motors for taking the power back to
the crankshaft I suggest you contact Light Engineering through

Thanks Randolph. The first one is too big for our purposes
and probably too expensive but the second one looks promising.
Do you know the procedure or method for feeding the power back into
the grid?
