Currently running 15psi but have it tuned as high as 19psi. The old clutch slipped under full power so I turned it down temporarily. I have a new clutch setup in there now that I will exercise on the dyno in the new few weeks to see what it will hold.

Kevin Norman It's actually an EGT thermocouple in the front header pipe. I have gone through many clutch setups trying to get things to hold. I am currently using a Barnett Scorpion clutch with CF plates and 540lbs of spring. It has held the most but still slips under full boost. I have 600lbs of spring but the lever pull is just too difficult for the street. Yes, hydraulic was considered but I'm holding off until I finish my new design for the clutch setup. Should give me easy lever pull and huge holding capacity.

Thanks! The front mask is from Shoyomoto. They are a Canadian company

Thanks! Stock fuel system can support ~110whp. There are several ways to give the fuel system additional hp capacity which your engine management strategy should define. My stock 2005 bottom end handled ~187whp/149ft-lbs without failure, but I can't say how long it would have lasted. The failure was due to operator error. Your 2009 has a better crankshaft & rods too. Forged pistons are a great idea, but no need to drop compression. I just built a turbo XB12 with 150whp/137ft-lbs with 9.6:1 CR + 13psi boost using the same crank&rods you have + off the shelf forged pistons. Tuning and proper design are the most important factors! Cometic MLS head gaskets are necessary too.

ezracing900 , thanks for the reply, that's very helpful. You are definitely the best resource for turbo xb's. It's hard to find go information on these bikes anymore.

I used an electric oil scavenge pump, a Marco UP2, to pull the oil from the turbo drain and pump it into the oil tank in the swingarm.

I haven't painted them. I have just kept them very clean. Even I am surprised with how glossy they have stayed. I have seen many other well cared for XBs with black plastics that are not nearly as glossy.

Cheers, mine have stayed reasonably good although I don't think that come anywhere near your standard. I hit them with some cutting compound and it took scratches out of the rear seat cover. Didn't want to get stuck into them too hard in case it actually took the gloss away.

I sold it a few years ago. After building the 1st turbo setup for it in 2006, I put over 25k miles on it over 13 years. During those 13 years, I upgraded/changed the setup several times. initially, the setup ran ~12 psi of boost, but the final and most recent/powerful build ran 22psi. Each of the build phases used the same Garrett GT2252 turbo with a few different turbine housings/wategate setups and some minor compressor cover modifications.

They are a pair of Gloworm X2 LED lights. Not DOT approved but fit well within the fairing openings and throw a lot of light. They require additional electronics to drop the bike voltage to ~7.2V as well.

I sure did. I mounted the turbo below the motor around 2008 and it keeps evolving. I have modified the factory ECM to adjust fueling based on manifold pressure and use an electronic boost controller. There are no piggyback systems on the bike. I am currently working on reprogramming a newer DDFI-3 ECM to work with the cam position sensor. Once I have that working, I will have much better control over fueling and ignition timing, not that it is bad now. It currently runs great with the modified DDFI-2 ECM but the newer DDFI-3 ECM will offer some major refinements.

When you get your maps figured out, I'd love to have a copy, I'll even pay you for them.

I don't think I'll share my maps but if you have any specific questions, let me know

Very few options to change gearing with the belt drive. The chain drive sprockets were much easier to find and gave me far more final drive ratio options.

This was from showyomoto.com, but this was ~10 years ago! Not sure if and where you can find this mask these days

I have LEDs for check engine, oil pressure, neutral, and low fuel on either side of the gauges. I dont have a speedometer but I know approximate speeds based on gear and rpm.

ezracing900 dude that's how I'm driving my car right now, just rpm baby, getting tired of it though😁

ezracing900 But maybe a little tiny digital speedometer would fit in the middle of the handlebars?

no need for it and extra gadgets add complexity, extra wires, and more hassle. I only have what I need

No, they are Gemini Duo led lights in a custome fairing and electrical setup

This is my old system. Fuel system was 80 lb/hr injectors with Walbro 255 lph fuel pump and Turbosmart FPR. New fuel system will be 2x 60 lb/hr primary injectors + 2x 80 lb/hr secondary injectors + ECM controlled PWM fuel pressure regulation + Racetronix turbine fuel pump. Old system ran ~22psi of boost and new will be about the same but lots of other changes/improvements.

ezracing900 Thank you very much fpr the reply! i actually live near East troy WI where buell is. My v rod uses stock fuel pump and injectors. tapped a reference hole to the backside of the FPR and ran a line to the compressor side of the turbo. injectors are maxed out but keeps up with the 9psi. garrett T3 of a 89 saab rebuilt by Precision 36 rear ar turbine housing 60trim front of svo 4cyl mustamg t3 turbo. kind of. a frankenstein but it works great. Stock engine is 11.3 compression so 9psi is about as high as i can run without less compression n its fast enough. I am very interested in turboing my new XB12scg. be great to here your take on what turbo , wastegate, ect to run with a certaim goal in mind. New bike is an 09 xb12scg. Thanks again for the reply. love buells coupe other buddys have em. rschlieve454@gmail

That big disc

Me permite ir al bano por favor

This kit is not available. It is a custom 1-off setup that I made.

ezracing900 Hello friend, some time ago I got in touch with you regarding the transmission kit that rode his Buell. Could I pass the material specifications used in crowns (or are other bike?), And which motorcycle drive chain is? I am here in Brazil with my stop Buell, and would like to know how did is adaptation. If you can give me all I thank you. If I can put this kit on the market here, give you a percentage on each sale, Ok?

Hit 186hp a while ago at 19psi with a slipping clutch. I have a new clutch setup in there now that I will test in the next few weeks. It should put 200+hp to the rear wheel

damn... a lot hotter than I thought . how much did all the mods end up costing you?

Depends how far I go back:). If I were to build what I have now again, I think it would run around $15-20k

damn.. I got 2 XBs 9SX modified and 12R modified.. I actually like my 9SX better than my 12R on the street.. Im thinking about bumping up my 9s horsepower though.. maybe heads and cams or something.. not sure what it would all cost.. I really am only looking for like 110hp at the rear wheel..

Cool. I've read your posts on BuellXB.

no gauge, just a low oil pressure light

ezracing900 still a badass build. Well done.

In its most recent format, she put down 181 whp & 172 ft-lbs
