Cummins vgt build

[volvoguy]

For starters this will be my first turbo jet build, ever since a kid I have been fascinated by the jet engine so here I go living a dream of making something that makes cool noises and a possible fire hazard.

For the build
The turbo is a he351ve (veritable geometry)
Inducer diameter is 60mm. The turbo can flow 70lb/min
Oil will be supplied by a gear pump.
Fuel will be propane unless someone changes my mind.
All parts will be stainless scraps from work.

All input is appreciated, come share a laugh and help me make my neighbors happy.

Hi

A 60mm inducered turbo is best flowed at only ~50 lbs/min as a gas turbine , you want to run the comp in the most efficient region of the map rather than right over in the choke region at 70 lbs/min with poor efficiency , with poor comp efficiency the turb stage needs to work too hard to drive the comp meaning more pressure energy is used in the turb stage leaving less downstream for producing thrust/shaft horsepower.

You'll probably find that once you find the sweet spot for the variable control you can lock it in position, better to begin with the variable in the mid position .

What dimensions are the turbine wheel ?

All the best with the build :-)
