Selling my father's Graupner G-Booster 80+ Turbine that produces over 19 pounds of thrust and is full kero start. Basically the same as the Evojet 90 turbines but this has two fuel solenoids instead of the one. These things are tiny but produce huge amount of boost which was often UNDERated at 19 pounds.

Complete kit including the Fuel pump, two solenoids, ECU, Turbine, and all wiring. ECU shows 15 hours of time on the clock but I know for a fact that the turbine was rebuilt which included new front and rear bearings before it was put in storage and the work was performed by Diddi (creator of these turbines and he still services them). I have receipts showing over 350 euro's in parts and labour. I would assume no more than 2-5 hours on the new bearings.

NOTE: I have tried to start this turbine myself, but I keep getting a badg error indicating the glow plug issue. This could be an extremely easy fix, or replacement of the glow plug itself. I was quoted 100 euro's from Diddy, but I don't have the time or expertise to do this myself so my asking price reflects the issue as I am selling as-is.

Turbine has a few dings and scratches on the body (as I tried to show as best in the pictures) but otherwise the blades and everything else looks great! It turns over smoothly with no indication of issue with bearings or anything. Fuel pump, starter motor and solenoids all work perfectly via testing on the ECU menu.

Brand new was over $2500 and I'm looking to get $1100 and I'm located in Toronto, On
