Instructables

Step 2: Get yourself a turbo charger and hide away in the garage building your insane jet powered contraption!

Use care when selecting your turbocharger! You need a large turbo with a single (non-divided) turbine inlet. The bigger the turbo, the more thrust your finished engine will produce. I like the turbos off of large diesel engines and earth moving equipment. The use of one of these turbos will yield enough thrust output to move a vehicle of some sort pretty well. It is best to buy a rebuilt unit if possible. Ebay is the way to go here, as you can really save some money.

As a general rule, it is not so much the size of the whole turbo as it is the size of the inducer that matters. The inducer is the visible area of the compressor blades that can be seen when looking at the turbo's compressor with the covers (housings) on. Looking at the turbo here will show that the air inlet is quite large at almost 5 inches in diamter, while the visible blades of the inducer are only 3 inches in diameter. This is plenty for creating enough thrust to drive a mini motorcycle, go kart, or other small vehicle.

The turbo in the picture is a Cummins ST-50 off of a big 18 wheeler truck.

okay now I have question on the divided non-divided thing.if I use a divided turbo charger will the amount of thrust acordent to the fuel and burn decrease there for my acceleration ultimately becomes less and more of a hastle or will there be no difrence.also does size make a difrence or is it simply nothing at all because I'm building a tiny little gocart thing and I want the powerXweigt=thrust ratio to be correct so I don't kill my self

Can anyone tell me why it must have a non divided inlet? If I have one with a divided inlet can I just machine out the divider? Thanks
