And Thanks to guys from Twinmotocycles.nl
Guys from HammerPerformance, they make a good job.
 
Wow! Lots of work I see! I bet you are excited to get it cranked up!

A few of questions:

Is the turbo CHRA positioned upside down so the oil supply is fed into the oil drain port of the turbo?

Is that an EGT thermocouple right before the turbo?

What is the part below the AEM water injection controller?

Is there a turbo support bracket coming off of the oil cooler subframe?

I've never heard of a Garrett GT2522 ball bearing turbo. Where did you find it?
 
I plain to get about 180-200HP at wheel

Hi EricZ
Yes, really a lot)
I remember your words in pm - "LOTS of work and EXTREMELY expensive"

"I bet you are excited to get it cranked up!" - ohhh yes, i start the engine 2 days ago and i was really happy.

1. Yes, exactly, i will use scavenge oil pump to help the oil cool the turbocharger.
(http://www.turbowerx.com/Scavenge_Pumps/page1/page1.html)

2. What termocouple? blue one? It is Silicone, that is gearbox breathing hose.

3. That is intake solenoid. I have japanese model. Offcorse i have no mufler control system, but anyway i am still not sure what that solenoid no need me.

4. Here is detailed picture of turbo support:

5. Oh, yes, I was wrong, it is GT2554R
I chose between them, confused in the names.
 
Cool. A couple of comments and suggestions.

The turbo is mounted to the exhaust which is mounted to the motor. Unless you have a flex coupling in the exhaust between the motor and the turbo, the turbo needs to move with the motor and not be mounted rigid to the subframe. The motor is rubber mounted so it is allowed to move relative to the frame and subframe and, as a result, the exhaust system will crack or break very quickly.

The turbo CHRA always needs to be positioned so the oil inlet is at the top and the oil drain is at the bottom even if you have a scavenge pump. Otherwise oil will leak into the exhaust and intake of the turbo.

It looks like you have water lines hooked up to the turbo too. Where is the radiator mounted to cool the water? You don't need to run water through the turbo, especially since the turbo is as exposed as it is. The electrical demands of an electric oil scavenge pump, water injection pump, and a turbo water cooling pump sounds like it may overload the charging system.

The sensor I was asking about is shown mounted right before the turbine inlet on the turbo. It looks like a compression to 1/8NPT fitting that holds a thermocouple. If it is a thermocouple, it should be mounted much closer to the engine. The exhaust will lose a lot of heat between the cylinder heads and where you mounted the turbo and so any EGT you read near the turbo won't tell you anything useful.

Just trying to help:)
 
I will be very glad for your comments and suggestions Ericz.

About the flex coupling, i am allready think about it. I will do this for sure.
If i will no use flex coupling i think my frame wich hold turbozcharger will be cracked shortly.

Thanks for suggestion about the oil drain. I will rotate oil drain, i am glad what that's easy.
Oil hose is not connected to the turbine yet, so I do not get thi8s problem yet.

Water radiator is mounted at the bottom of the bike. You think turbocharger will work without the water cooling?

Turbowerx oil pump is only 5A nominal, water injection will work only at maximum rpm and pressure, so i hope the electric system of the bike cope with that.

Oh yes, now i understand what do you mean.
Right after the engine i have one sensor. That one is for pyrometer, especially i want to try control temperature of the turbine first. I want to control temperature changes first. For example if all the time this sensor will show 1,5F... i will think that thats standart temperature, if the temp will rise up i will think what something wrong, with the cooling for example.

Extremely grateful for your advice Eric, it is difficult to engage in such projects in the place where I live, no one to consult.
 
Absolutely sick sir. [up] Looks like you've put a LOT of work into this. Looks great and I'm sure it will be a beast once it gets up and running. Best post some vids of it in action

I like the frame paint. Very subtle. :D
 
I'll give you an A+ for effort...but...I'm very curious how you're going to route the exhaust from the exit flange. Your left leg is going to experience a whole new level of frying that will make Colonel Sanders jealous.
 
Damn in the living room?!

A-ha-ha))) Thats two story house.The back wall of this room is a sliding glass windows. So, is Ok. Outside is too hot):)

Yes in the living room, that buell just made itself feel right at home.

Yeah, exactly!:)

When i seat on the bike distance from exhaust pipes to my leg is about 20-25cm, is more then enought. Also that 2 exhaust pipes maded from titanium. Not so hot as steel maded.

A\F is not ajusted yet, next week i will go to the Dyno...I promise to shoot a little video...
