What Type of Turbocharger?
The golden rule here is the bigger the better. Something from a large diesel engine such as a 4×4, truck or large generator. It needs to have an inlet of about 2.5 to 4 “, no waste-gates and no bifurcated turbine scroll. I was lucky to find two large Schwitzer turbo’s off E-Bay that were going cheap and were ideally suited as a jet turbine. They are both enormous and dwarf the turbo on my 200 Tdi Landrover. Each weighs in at 25 kg. You can source turbochargers from a scrap merchant, but these are not always in good condition with poor bearings and damage to the vanes. New turbo’s suitable for DIY jet engines are available but expect to pay a small fortune. Construction The essential components required to build our jet engine in addition to a suitable turbocharger include a combustion chamber, an oil circuit and a fuel delivery system.In addition we will need monitoring of the various engine parameters including oil pressure, P2 (combustion chamber) pressure and the exhaust gas tempera
