Its a Bosch fuel pump.

Please keep in mind the maps I sent you are much greater than one to one,,,,, So,,, you will be lean up top. Once again AFR tells all,,, think it out and go slow. Cheers.

Thanks I will do that. I will only use it as a base map and then dyno the bike with it.

Let me know how you make out going this way. Also, Curious to what your base pressure will end up being with a one to one reg,,,60 psi my guess ?????

You may run out of injector early in boost though ????? Thinking your Duty cycle will be over a 100% unless you get new fuel rail with bigger injectors.

Also maybe a elbow on the fuel return inside the tank so fuel return is sent away from pump. Thinking suck and return to close as shown. But looks great. Cheers.

Any pics of reg ?

I saw that problem with the return line and I actualy made a new fitting for it. Now the fuel will pass next to the pump instead of onto it.

The supplier I bought the regulator from told me to set the initial pressure to 3bar and in boost it will go up to 6bar.
I will only know once I get the bike starter and up and running.
I'm hoping to at least start it over the weekend!

Who's regulator, looks like Aeromotive ?

If he told you this is a one to one regulator and in boost it will go to 3 bar he will have to explain how ? If you start off at 3 bar 42psi and go one to one with 8lbs boost that would = 50psi correct ???. Your motor at 50 psi may Not survive Dyno Session.

IMO,,This will never work with your stock injectors and you will lean out in a hurry. Only getting one shot at this,,,, recheck, I could be wrong but ???????

Love where you mounted Reg. Will plastics cover & hide.

I will defiantly make 100% sure of the pressure at initial startup and once the bike goes into boost.
I have one problem that I cant get sorted out. How did you wire your new fuel pump? I connected myne the same as the standard one but for some reason all the engine lights and traction controlles are ON on the dash. I even tried it with a relay and the lights still come on. There is also only 5.57V on the wires if I connect it direct without the relay and with the relay connected it doesn't energize. This is the only thing holding me back now from starting the bike up

100% sure of the pressure at initial startup and once the bike goes into boost.

This bike will go into Boost Fast. This is when damage can occur. Should check before start up testing.

hmmm, I can't remember any issues. Maybe Boch wires reversed ? Do you have a meter ? Hard to help on the net. pull pump hold in hand confirm it's starting to prime than shuts off. Start here. Going to be something simple.

Also keep in mind that is a big pump and will draw more current. Where is your turbos oil pumped wired in ? If your on same circuit, fuse will blow as soon as pump has to push 90 psi. This will be when the Current draw becomes greater than fuse. I learned this at wide open throttle under full boost. Scary, thought I should give you heads up.

Thats the thing, when I turn the ignition on there is no prime sequence.
Yes I have a meter. When I check the supply voltage it is 11.65v with no pump connected. There are three wires in the plug, I checked and one is the positive and then there are one negative and one ground, the ground is connected to the plate mounted to the tank. I did check the polarity of the pump by connecting it streight to batery power.

I did have the oil scavenger pump connected to the same positive as the one from the pump but have since disconnected it to get the fuel pump problem sorted out first. I will just check the fuse to make sure it did not get damaged but I still get the voltage on the plug.

Do I need to connect both the negative and the ground wires together? I also saw that my fuel indication shows full but flashing. Why will this be as there is a seperate float and wires.

Yes I have a meter. When I check the supply voltage it is 11.65v with no pump connected.

With pump un plugged you should voltage drop out after prime,,, Does it ?

Place your meter on ohms scale and confirm negative wire is not open ? Pump will never fire if DC voltage has no path to ground. This has to be it, if you have voltage on the positive. Get this confirmed then plug pump back in.

I finally got the problem sorted out! Thank goodness I downloaded and printed out the manual I found on Bikeland!
The main ECU fuse was shot. It must have happend when I was trying to make ends meet of whats going on lol.

I also started up the bike just on idle rpm to see if there was any leaks. She sounds supper good!!!
I just need to find a beter vacuum as the one I'm using is not a good one I think. I T'd off the idle solenoid valve and my boost gauge is jumping all over the place!
Where and from what point did you T off? I see there is some small gray with white stripe tubes thats on the back side of the TB, is that also a vacuum line?

Also one quick question, do you have a restrictor in your oil supply line to the turbo?
I have the oil scavenger pump that I bought from Cyclelogic on the return side back to the oil filler cap.

Ahhhh, you said you were hot on the red so I move forward. Must have blown afterwards. Glad you got it.

What are you doing with Vacuum signal ?

Where and from what point did you T off? I see there is some small gray with white stripe tubes thats on the back side of the TB, is that also a vacuum line?

You should see one hose from each throttle body T together with hose going to map sensor. Not sure about where idle signal is sent from on the new bike. You must place a one way check before map sensor so Map sensor does Not see Boost. Important step.

Also one quick question, do you have a restrictor in your oil supply line to the turbo?

Yes, with out it, Turbo fills with oil and takes a long time to clear.

The vacuum is used for the dump valve as well as the fuel pressure regulator. I had my boost gauge also on the vacuum but its all over the place under boost.

Thanks I managed to find out that there is a restrictor on the inlet of the turbo. I also removed the flange on the drain side to see the amount of oil coming out the turbo whilst running. The scavenger pump will be more then adequate to remove the oil from turbo.

I loaded one of your maps and took the bike around the block. I kept it under 4000rpm just to see if every thing is in order for the dyno. I'm taking the bike to the tuner tomorrow to get set up. There is a drag meeting I would like to attend over the weekend so hoping that it would be done and ready

Well,,,, do tell

Every thing seems to be going good untill the rpm pick up, the oil scavenger pump can not keep up with extracting the oil from the turbo and starts pushing it past toe seals and out the exhaust. I made a small "oil catch tank" with a big inlet so the oil will firts come out the turbo with a 16mm tube then into the oil tank. The scavenger pump will then remove the oil from the tank back to the motor. Dyno to continue after instulation. Will keep you posted.

Need more of a restriction.

Even with the catch tank the oil flow was still to much. I brought the bike home again today to start stripping. I will post a pix of the restrictor thats in there now. The guy that I baught the turbo from said I could go down to a 2mm hole in the restrictor. I want to send the turbo off to him just to have a run through it to make sure the seals are still fine. Luckely he suggested it and at no charge. He also said he can get me a scavenger pump with a 16mm inlet and outlet. So I think I'm gona go for that option as well just to be on the safe side.

I hope your taking lots of pictures ? I was debating a catch can for the crank case vent tube,,, would love to see what you have come up with. Cheers.

Just as a bit of additional info for you I did some tests some time ago on the oil flow to the turbo and from the drain side of the turbo.
I tried different sizes of restrictor bearing in mind the size of the -3 pipe to a roller bearing turbo, (these need less oil than a journal bearing unit), I found that a 0.9mm restrictor did sufficient. I tried without and that gave too much oil. Dont have the figures just here at the moment but from idle it flowed something like .......Ill dig the figures out to be safe!
I have used my bike for the last 4500miles and its no problem.
Im sure it flowed around 1.25 litres per min at idle and about ....2.5ltrs/min at 3000rpm (used this figure because of the blow off valve in the pump it seems as though not much more oil flows beyond these rpms.(thats with a 0.9mm restrictor.
Ill see if I can find the figs but I would say this is the general size that seems to work best for my application.
We have alot of experience with these turbos and even in a motorsport application this is the general size we use.

Romans: The catch tank was for the oil return out of the turbo. It did'nt work so I removed it. I orderd a new pump today with a 16mm inlet/outlet so hoping to get it ASAP!!!

Grinner: Thanks a lot for the info I appreciate all the help I can get!
