Turbo charging my B12

[vizman]

it'll be ok....it just won't boost very well........if at all....just make sure your oil feed/return is working.

[majortom4]

That's the first thing on my list to fix, going to a hydraulic shop tomorrow to get a new oil feed hose.

ill try and fix the leak then.....

so happy it runs tho!! Didn't think it would start as easily as it did. Was worried it would flood or not start at all.

Where did you find your Busa pistons eventually? 

[majortom4]

Got them off Eblag eventually.

not putting them in just yet as can't afford the bore and gaskets and everything will get them in soon enough.

Let me know if you'd like to free up some funds haha

Hi guys. Need to pick your brains.

bikes all built and running.

going to take it to a dyno and get it set up but the dyno near me hasn't set up a turbo bike before. 

Any help with this of how I would set up the jets and stuff for lean or rich running??

All help is much appreciated :-)

[vizman]

I'd have thought it pointless if you still have holes in your manifold...or have you fixed that?

[majortom4]

I have sorted the holes as best I can, maybe a tiny one here or there.

want it rideable now while I save up for a professionally made manifold.

Been a while since last update.

bike been on the dyno thanks to @1260pete. All set up and running 188 bhp at 8 psi of boost. Going to take it for a spin tomorrow with GoPro on so hopefully get some forage.

Again want to say a massive thank you to everyone who has helped me out with info for my build. Has been great fun. 

Next thing on list to do is forged Pistons and up the boost!! No doubt will be needing people's wisdom again :-)

[Captain Chaos]

188 bhp @ 8psi is not bad at all. 

 

[majortom4]

Need some advice again :-)

so after finally getting it out for a trip to the shops and back. When I return to my bike after getting some more oil for it. I come back to a puddle of oil that had dropped out of my air filter. Can't figure out why!!! It happened before and thought my pump was in a bad place and not drawing the oil back down the return. But after moving that closer and checking it works well it still is doing it :-( doesn't leak when running tho...... 

Any ideas guys???

[vizman]

you need to let the pump run for a bit after you stop.....still a fair bit of pressure in the oil system when you kill your motor.

As viz says,run the pump for a few seconds after you stop to pull the oil away from the turbo,I run my pump from a stand alone switch so I don't need the ignition switched on to do it.

[slingy1157]

As has been said, it takes some time for all the oil in the gallerys above the main oil gallery where the turbo feed is taken from to empty after shut down, and while this is happening oil will still be siphoning into the turbo. It is actually better to have the pump as far away from the turbo as possible to give a bit of volume to fill with oil while this is happening. And let the pump run a little after shutdown or fit a check valve of some kind. Oh and Merry Christmas everyone

[majortom4]

Thanks for the replies! 

I have the pump fitted with a separate switch. Will run it for longer next time after running and see how it goes. 

Merry christmas everyone!!

[majortom4]

Thanks! Not yet unfortunately as the weather has been awful and it's still leaking oil. Will get some soon hopefully!
