  1. Never seen it done and if not trying to do anything clever are you gonna really see it when pushing it at speed and concentrating on next corner come up. If take it too pub fair enough you probably will see it.

  2. Got to say Clive thats looks awful.

    At end of day the scavenge tank needs to be big enough for when you shutdown as there is still pressure in the system that pushes into turbo for quite some time. I used check valve on flow pipe and along with sump stopped any smoking on start up.

    I'm totally impressed with my home made mechanical pump too.

    Happy days.

  3. Clive i could not see why up would want to vent scavenge tank at end day the pump always needs a head of oil to work there best, mechanical pumps certainly need this why wouldn't the little electric pumps be the same.

  4. I must got unlucky with last on i did as had use carbide in the lathe, but it did tap ok after so just must been hard spot after hearing about your results. 

  5. With ya springs Greg I looked at charts and got confused as nothing seem to match colours for what psi i had so I connected wastegate direct to compressor using a simple air reg with gauge. As you see piston start to lift as you wind up air pressure that gives accurate psi reference for spring or springs. Worked for me especially as raided friends box springs. Sadly I only found 1 bar and 19 psi, the 19 made fueling proper lean out, which found confusing as 1 to 1 boost reference reg I Would have thought would sort this. Anyway still learning alot when comes to these hair dryers.
