HX35 Gas producer garrett style

[turbinenjoe]

I used a VW Golf III style power steering pump as an oil pump for my HX60 turbojet.

This pump was also used in quite a few Audi models.

I powered it with a DC motor of a heater blower (can‘t remember if it was also Golf III or Opel Corsa). A belt drive with pulleys was needed to reduce the rpms of the motor. 

The pump that i use is old and a bit worn out. That leads to the effect that especially in cold weather it needs high rpms to prime the oil flow. I guess the vanes stick close to the center of the shaft and have to be pulled out by the centrifugal force at high rpm before the pump can create enough suction to pump the oil.

If it will help I could take some pictures of the pump.


Best regards

Hi,im also planning on using a Golf pump now but the IV one. Im not sure how similar they are but they look pretty much identical to me. I want to install it properly but since there is not much time left i may even weld the lines if there is no ther option. As far as driving it goes, i was planning on making a little temporary jig for my cordless drill to drive the pulley using a friction wheel (that i just made on the 3D printer and put rubber on it).

Oh also i switched back to a can style combustor because i couldnt rotate my turb housing as i wanted...
Anyways you may want to look at the new hole data:

FT OD: 125mm (around 12.271 sq mm,which is atound 5.3x the comp inlet area, i read that atleast 3x ind. area is required though most guides state 3x ind. diameter)

FT Lenght:27cm


Primary: 16x 6mm holes (8 on front wall)

Secondary: 12x 7mm

Tertiary: 12x 11mm

Fuel will be radially injected propane via a central tube, later i will probably redesign the flametube to accommodate a single burner.
The reason for the 8 holes on the top wall is so i could have a shorter FT, as far as i know its fine to put around a third of the holes on top.

And as usual:

Hi Neo

If using propane you can reduce flametube size , so 3 time inducer AREA for flametube cross sectional area would be OK , it would also be OK with liquid fuel injection if its done to a high standard .

Holes sound OK
