Hi Jamie
You might be able to procure different seals , its a popular Brand so finding out if they're available shouldn't be too difficult .
Yeh , just keep an eye on oil supply at the turbo , you could add a pressure switch (at the turbo oil inlet) to deactivate the fuel pump if lube pressure drops below 40psi .
Cheers
John

mcmaster carr would be a good place to find the replacement seals
I was looking at a different shurflo pump but yours is better, odd how it's nearly impossible to find an electric pump designed with oil transfer in mind...
It will defiantly move it when it's warmed up though...

more work completed on the turbine. got most of the custom hydraulic hoses mounted. Also, ordered the replacement diaphragm for my oil pump so it will work with oil.  Will probably mount the gauges/switches this weekend. Jamie |

Over the weekend, I broke out the plasma cutter and knocked out holes in the instrument panel for the switches and LCD panel. I still need to cut holes for the gauges. Coming along nicely. I still like my friend's idea of putting 4 risers in the corners and putting a piece of glass over it and making a coffee table out of it.  Jamie Attachments:

Hi Jamie I notice you have a "rubber" hose for your lube supply to the turbo , not a good idea , the radiant heat from a red hot turbine scroll with have it catching fire pretty quickly , always use metal plumbing for pressurised lines anywhere near the hot bits , you'll need heat shielding . Also its advisable to read oil pressure at the turbo lube inlet port in case there is a restriction to flow between pump and turbo resulting in acceptable pressure at the pump but unacceptable pressure at the turbo . Is that lube tank breather still connected to the comp inlet  .....................not good, as it'll "wet" the comp wheel and combined with dust particles degrade your comp efficiency . Otherwise , she'll looking a sweet build :-)) Cheers John |

John - I will most likely add some heat shield material to the turbo oil inlet. As for the pressure reading, I am using one of the ports on the manifold to read it. As for the tank breather, sigh... yep, it's still on the intake. The way my tank fittings are welded in, I would have to weld in a new one on the back side requiring removal of tons of stuff. If I decide to put on a free power turbine on the backside at some point, I will upgrade that. "Otherwise , she'll looking a sweet build" THANKS!  Jamie |

VERY close! I got the electronic oil temp gauge in the mail yesterday... will probably mount that tonight and get the last of my oil/pressure hoses. I plan to sort out the electronics this weekend. Then, the only thing left is the propane inlet to the rig... and then, getting up the cajones to start it up without skidmarking my pants |

Good luck with the startup! |

Got the omron sensor and lcd readout hooked up. Also, most of the wiring is done. Ordered some header insulation wrap for the exhaust tube that goes into the turbine. This will help keep the heat away from everything else.

Hi Jamie
You may need to wrap the entire turbine scroll housing to prevent radiant heat from getting to vunerable parts .
Cheers

HI JAMIE NICE WORK. YOU MIGHT TRY A WATER INJECTOR IN THE EXHAUST JUST AFTER THE COMBUSTER. IT HELPS KEEP THINGS A LOT COOLER AND YOU ARE GET SOME FREE STEAM POWER. AUTOMOTIVE FUEL INJECTORS AND WINDSHIELD WASHER FLUID WILL DO THE TRICK . A SUNDSTRAND OIL FURNACE PUMP WORKS OR YOU COULD JUST USE A SMALL TANK WITH AIR PRESSURE ON TOP OF THE LIQUID. I DID TRY TO USE LIQUID PROPANE A FEW TIMES ONCE I EVEN RAN IT IN TO THE OIL TANK BY WAY OF SMALL STEEL COIL IT DID HELP COOL DOWN THE OIL . I NOW RUN A MIX OF 75 PARTS DIESEL TO 25 PARTS METHANOL. AND CAN RUN FOR AS LONG AS I WANT WITHOUT OVERHEATING . KEEP UP THE GOOD WORK
