this might help you with a pump Electric Oil Feed and Scavenge Pumps

did you tap into the correct oil pump? there are two pumps. one pump supplies the oil tank and the other pump supplies the oil from the tank into the engine. that oil pressure seems a bit on the low side.

Yes I did. The scavenger pump returns on the other side of the motor.

ok good. my yfz450 has the pumps back to back on the same shaft.

mine only has the one pump in the motor, thats why I was skeptical, about using it.

instead, I used a scavenge pump, a oil cooler, with a seperate oil tank, for my secondary oil system.

Im using the scavenge pump, to pump the oil to the turbo, then drains back into the tank, I might switch it to pull oil from the tank, to the turbo then to the pump, back to the tank.

the way it is now it has to much pressure, it blows the lines off when its on...lol

I think switching it will work better?

post your pics any class900, mine looks jaked up also and I posted mine....lol.

Its really easy for me to plug into the scavenger pump.But the problem is the Cdale is a dry sump,so it also pumps a lot of air. On top of that its not filtered oil so.

Guys with a 400 cc Honda there is no such thing as too small a turbo,make sure that the turbo is mounted as close to the head as possible or you will lose too much heat in the pipework dropping the turbo's efficiency leading to a laggy unresponsive setup that will be almost impossible to tune properly,Our Team Rocket factory Explosive racing Turbo 700 raptor uses a garret gt 2560 hybrid modified from a Sanyong Musso Turbo Diesel 4WD but it runs methanol an measures 804cc with a full Stand alone EFi system.
It also cleaned up at the 2009 Four Stroke Association 4 stroke wars at Glammis taking outright king of the hill ,650 power adder and stock chassis classes ran 11 passes back to back you guys tried to break it and many there considered it dirty tricks thanks to all those who gave us Nitrous bottles to cool the Inlet system between passes it hung together and made our trip from Aus worth while, we will be back.

Thanks Coxy. I had also heard with a single cylinder that the intake volume has to displace at least the same displacement as the motor cc?

Heres so info for the Carb guys. DIY turbo bike (and car) basic questions

I wanted to give this a bump and see how your build is going?
