SR1 turbine, based on Holset

[sven]

Hi,

Today I ordered few pieces for my turbine

switches 5pcs led illumination



Silver solder, high content silver



Laser RPM meter



300w 24v motor for oilpump



Gauges






9-28V 30A DC Motor Speed Control PWM



0.7mm ss tubes



K type probe up to 1200 c and display




Servo tester



Oilfilter couplings



For oilcooler gonna use old AT cooler, also I managed to get couple new fuelpumps for free, that made my day.

it's no fun to just buy everything that you know will play nice with each other...

the real fun doesn't start until after the busted knuckles and the associated swearing fit happen

Hi

I dont have milling machine, its cheaper to buy some parts like this olifilter housing. I dont know, but only thing here on the list, what I may build by myself is pwm controller. I have drawings made for controller, but this box was only 15 eur( same price for only components to buy separately)
I already have fun building this project and thanks for jato forum I have managed to get this far.

Today I refurbished my used powersteering pump, now I have to figure out the best way,how to connet it to the dc motor.

Cheers

Little build progress

I cut vanes into right height and shape, also made vane top ring.

Couple pics





Also bought stainless steel tubes for making oil and fuel tank.

Quik question, Im was thinking about oil lines and Id like to go with AN type fittings and stainless braided hoses, I was thinking about use AN8 size for pressure side, and AN12 for free flow. What you guys reacon?

Hi Sven

The bore of the drain tubing needs to be the diameter of the drain hole in the turbo's centre housing , most a pretty big .

As for the supply line sizing , as long as the pressure gauge reading taken from a pickup at the turbo's oil inlet port is indicating the desire pressure then its big enough .

Then Im on the right way, thanks again John

Need to be careful about the braided hoses, most likely they will not handle the temperatures (the rubber liner not the braid) of the exhausting oil and/or the core case temperature.

Hardlines seem to be the easiest way to go, and with AN fittings, your flare angle will be known and easy to get a flare tool for.

Hi and thanks for reply

Good point, I was thinking about use ptfe and stainless braided hoses(not regular rubber), and turbine side gonna get heatshielded, oil exhausting gonna be stainless tubing. Manufacturer promises 180 celsius for ptfe hose, before going bad, with oilcooler I hope to keep temperature lower than that
Lets see I have so much do to before that, weekends(sometimes even not then) I have only free time to build my projeckt, wish I have more time
Sorry for my spelling, its terrible :S

Cheers Sven

I had free time at this morning, so went to the garage.

Welded clamp holder/turbine leg together.



drilled holes to attach vanes and upper plate together.






My dc motor arrived, so I tried the way how to connect it to my Oil pump.




Cheers

Today my old friends visited me, I showed them my old project(valveless pulsejet engine) they never seen anything like this before

First startup video for you guys, just for entertainment:)
At this time gas valve was too sensitive, fixed for now.
