Hi all
Has anybody ever used a variable vane charger in there build, ive managed to pick up a good condition working one free and am about to embark on my first small jet turbine project. Any info will be greatly appreciated.
Many thanks.

I've used one, from a nissan patrol 3L turbo diesel.
The turbine is a bit small compared to the compressor - for jet use.
I ended up removing the variable vane setup to increase flow through the turbine side.
The engine ran really well, but exhaust temp was fairly high (around 700°C at 1.5bar or so boost)
I then replaced the turbo with one from a mitsubishi starion, which has a similar sized compressor but much larger turbine, and had EGT of around 550°C at up to 2bar.

Thought about removing the vane body myself seeing as the operating temp is much lower on a car. Wasn't sure if i should leave it in in-case i could utilize it at a later date. Just as long as i can get it running n dip my toe in the world of jet propulsion, then with it running i can make alterations/modifications etc.
Many thanks.

I think if the compressor and turbine sizes are about right there's no need for the vanes, so you may as well remove them for better efficiency.
