Figured you turbo guys may want to see this early turbo mod and some purely home made engineering

xbob that was already answered shortly after you asked
"The rear rotor is a piece by Braking Under Control, an English company I believe."
i'm guessing that eric was on the comp at gainesville hd and buell and thats why it ended up as saying it was a post by buellgator i could be wrong though |

"Do you mix Isopropyl alcohol with your water injection?" You gotta be kidding me, that kind of alcohol will mess up our injectors. You have to use denatured or toiline. (sp?)
I think the best thing about this turbo bike is the way he using the existing headers and made it pretty much bolt-on. He made the whole thing a lot more marketable by doing so. |

I have hardly used my 05XB12 due to work and, er, Bad Weather! I have been 'made an offer' for it...but now I've seen this I'm not so sure I should sell!
Will a 'howto' be posted on this bike. I'm certain it would be well received!
Top stuff. It's Phat. It's 'sick'. In a good way! |

That was me on the Gville hd computer. The saved passwords suck on this forum if you are someone else trying to post.
I have just thought of some new designs for the turbo kit that will make it MUCH more simple and space saving too!!! I will be working this weekend to see if I can make the changes and, if they work, will be super!!
I am sorry but at this point there will be no "how to" for the kit. I have too much time invested into the design and I think that even if I spelled it out there are certain construction qualities that must exist for the setup to be as reliable and functional. |

Hey Eric maybe try out the plain blue windshield wiper fluid in your water injection. My friend has used it for about two years now in his water injection on his talon. He runs a hefty jet because he runs about 26 psi with a 50 trim turbonetics, I dont know what size jet you use though. When do you have the injection turn on, is it boost sensitive? Try to get some video on the dyno I would love to see and hear it. |

These are two of the first dyno runs. I had a different wastegate actuator on that didnt allow boost to come on like it does now. It also only peaks at 5 psi and now I see a consistent 6 psi. |

Looks awesome! I met a guy at Jennings this past Sunday who told me about it. Said he was a buddy of yours. |

MAN THAT THING IS NUTS!!! and really clean too. Are you goin to make it over to biketoberfest at all? Gainesville is real close, I might have to ride up there and check it out sometime. |

That spool up sounds awesome - didn't really hear much from your BOV - you only partially venting? Is your waste gate actuator electronically controlled? |

What did the whole setup set you back?, and how long do you think the motor will hold up to the boost. Did you use any different head gaskets. Sorry about all the questions but I'm curious- The whole build up looks tempting, right up my alley. Was that 5th gear you made the dyno pull with, because I could not believe how fast it pulled to top speed. I'm impressed . You might start a new group like the chain gang but with turbo's |

I had a few friends that went to jennings last weekend. Brian with his DRZ400SM, Greg with his Duc 999, and Matt with his RC51. They are all nice guys.
I would like to make it to Biketoberfest but since I work at the H-D dealership here in Gainesville I think I will have to work a bit extra!!
My BOV was working fine. Since I was still boosting pretty low and it was set on the stiff side it did not want to open much. Now that I am boosting to 6 psi and much earlier the BOV sound is more prominent. The wastegate actuator is mechanical.
I am still investing in the project since it is not actually "done" but currently I may have spent 7-8k on it. There has been several redo's for certain parts and designs and I have also been purchasing some things in quantity so if I wanted to do another setup it would not be as difficult to round everything up. I have tried to design this turbo setup to work on a completely stock XB engine and maintain reliability. As with every power increase you shorten the life of the mechanical parts but I believe that the stock internals are capable of supporting this level of performance. |

I think Greg was the guy I was talkin' to. He had his son there? Was sandbaggin' in the novice class?  |

Ericz, I didn't mean to indicate that there was something wrong with the BOV, I was mainly wondering if you had it set up to vent completely to atmosphere or if you vented some back into the intake tract. I found that only venting partially help deal with some stumbling when I let off the throttle. |

Dave-- It was Greg. I talked to him today and he said he met you.
Joele-- Oh, no, it is all vented to the atmosphere. I didnt think you had indicated something was wrong. How the BOV vents can play a big part in how the motor responds after a quickly closed throttle. Since the fueling is only basically based on the TPS and RPM values, any air that is vented to the atmosphere by the blow off valve is not a problem. The motor would normally see such a pressure drop when the throttle is closed and drop the fuel. If the engine management relies on an AMM or MAF to meter airflow to the motor then the presence of a atmospheric BOV can cause the A/F ratio to momentarily run rich and can falter. |

I realized, after having posted that, that our bikes don't have a MAF... duh me. It also helps that you don't have to deal with variable valve timing 
I bet that bike bumps against the red line a little too easily. |

Absolutely beautiful!! Anybody done any research on a turbo XB9? Can't they handle the higher rev's a little better? Keep up the awesome work and mail me an order form when you decide to market these. |

Red line comes on real quick. I am going to a chain final drive and will gear it taller so that I can stay in front of my fellow riders with the liter 4's past 120mph. Right now I walk away from them up to around 80 then they start to even up till 120 or so when I am about out of gear and then they pass me. I feel left out at the top end!! I think it will also help acceleration in 1st, 2nd, and 3rd gears since right now I shift through those three so quick the bike does not have enough time to build the really good boost!! |

Isn't that the story of the Buell. I can always run with the japs til 80-100, then pin it and creep to 120-125. I've had my bike up to almost 140, but now I can barely get it to 125. I'm feeling ya though. I need more top end, but I don't want to sacrifice too much low end in the process. |
