TURBOCHARGER SELECTION

THE TURBOCHARGER:

The principle criteria for turbo selection is cost since there will be more costs involved in other parts of the engine .It is better to obtain a good condition used turbocharger .The second criteria is that when it comes to turbochargers for jet engine conversion projects the rule is always the bigger the better. This is because small turbochargers tend to have low turbine efficiencies and mismatched compressor-turbine which is not good for jet engine conversion.The other important criteria is that the turbo should not have a waste gate and it should preferably have a non-divided turbine inlet.

        The turbo I could find was the Holset HX40 that I found in a used parts market .The turbo was in good condition but needed to be cleaned and lubed for use. However my turbo unfortunately has a divided turbine inlet .I have decided to go ahead with this turbo because it is very hard to find a good used turbo in the used market .I had to reject a lot of turbos with broken blades and other problems till I obtained this.
