Looking for a bolt-on turbo kit for my XB12S. Anyone know where I could find that? Thanks. /Björn, Sweden | ||

You bet! Walt Sipp - works as an engineer for Pro Charger. He also is a racer on Buells so he really knows the machinery. It is a SUPERcharger, not a TURBOcharger. Better throttle response. http://www.procharger.com/motorcycle.shtml You can PM Walt through his website http://www.waltsipp.com or through Walt221 here on Badweb | ||

Thanks Slaugther, but I am leaning more towards turbo than a supercharger. But will for sure check it out. Never say never... :-) | ||

I'm curious, why do you prefer the turbo? | ||
| Ferrisbuellersdayoff |
because a super charger has parasitic tendancies, it its power to make power sort of thing, as where turbo is power created from waste. I'd go for turbo any day man! Been looking at one for my Jeep for a few months now. | ||

There ain't no such thing as a free lunch. The turbo robs you of power at low rpms because of excessive back pressure until the turbine gets up to speed. There is also the dreaded "turbo lag" between the time you roll the throttle and the time you actually feel the power kick in. For all the "power robbing" noise people make about superchargers they tend to forget those annoying tendencies of the turbo. The supercharger also gives you "instant gratification." Although I've never ridden a "blown" motorcycle I've driven cars with turbo chargers and super chargers and I'd take the super charger any day. | ||

I actually talked to Walt about it when he was out racing at Willow. There really is NO throttle lag... and yes, you MUST use power to spin up a blower - whether by a belt or by restricting the exhaust (and getting that throttle lag) Heck, shoot Walt an email - you'll find he's a really approachable guy. You can also shoot Firemanjim an email. He's got his Bonneville bike in the works and if anybody knows the ins and outs of blowing one of these motors, it ought to be him. | ||

I prefer the turbo over a supercharger mainly because I find it easier to re-route the exhaust to spin the blower rather than having a belt from the crank or where-ever spin it. And since I don't do track racing the turbo lag is not really an issue. Ten years ago I might have started experimenting myself to build a kit. But now I simply don't have the time (or energy) needed. I want something that I can bolt on during a weekend and that has been tested and tuned by someone else. :-) Seems like Hillbilly motors in Germany has done some work; http://www.hillbillymotors.com/html/turbo.html But it looks more like a first trial rather than a proven concept. Yes, i will check Walts blower out :-) | ||

Whatever happened to the guy that was building these?    I remember about a year or so ago, he was posting here about putting them into production, but I was gone for a while and now I see no mention of it. Here's my favorite turbo of all time:    Then again, you could always go this route:  | ||

Eep. The thought of 3 NOS tanks 4 inches from my crotch would not sit well in my stomich. Cool as heck though. | ||
| Ducxl |
Uhhh,this is NOT a knock against but,can the rest of the Buell powertrain handle twice the horsepower a supercharger,or even turbo put out? I'm thinking grenade motor.These engines' aren't engineered for that much power | ||
| Jaimec |
Kitt Carson (yes, that's his REAL name), an MSF Chief Instructor for MANYS has ridden a turbo-charged Thunderbolt for a number of years. Don't know how hard he's ridden it, but with a name like that... | ||
| No_rice |
they seem to be able to handle a ALOT more power then they came with through everything. atleast from my experiance. | ||

The black bike with the Turbo is EricZ. He works at the H-D/ Buell Dealer in Gainseville, Florida and is still working on getting them to production. Give him a shout. | ||
| Ericz |
Here are much more current pictures of my bike. I am currently redesigning the turbo setup and expect to have things put together by sometime in Feb. PM me if you have any questions!!   | ||
| Ericz |
And here is a fun video...this is after I first got the thing running good...  | ||
| Jaimec |
This page (about half way down) has a photo of Kit with his Turbo Buell: http://www.jkminc.com/instruct.html Looks like he's left New York and is in Atlanta now. You Southern Boys oughtta go look him up! | ||
| Clutchless |
this message is for: EricZ ...Holy shit.... looks good so far, I bet its ear peircing to ride it tho. Makes some sense to me because of the bikes natural overload of low-end power, where the turbo is lagging. I imagine that mechanical drag within the tranny/driveline might make this a somewhat limited project. Do you get a little more top-end with that chain conversion? | ||
| Ericz |
What do you mean by "a somewhat limited project?" The turbo does a great job absorbing the harsh exhaust pulses. It is about as quiet as an XB with a D&D pipe. Of course it is on the louder side of the spectrum but I can live with it. Not a bad trade off in my opinion. Plus, the new design I am prototyping now will move the exhaust outlet much farther away from you and will be very acceptable. I think my current gearing makes for top speed around 150 mph and it will get there really fast. With the Lightning front end I don't want to go much faster than that. I have other sprockets for even taller ratios but around town 1st gear becomes a bit too much. The stock gearing makes for 1-4th gear on throttle wheelies with the current power output. It also made it easier when I converted to the longer swingarm. | ||

Beautiful bike man! That kit looks very clean. Does the charge pipe go up through the frame? I wonder if you can fit a air to water intercooler or something under the airbox cover. | ||
| Ericz |
There is room for a very small intercooler under the airbox cover but the intercooler would either restrict airflow too much or not have enough cooling surface, air/air or air/water, to prove efficient. I am running Aquamist water injection which works much more efficiently than any intercooler of similar weight or size. The only downfall to the water injection is that it is one more tank to fill, but lasting 3-5 fuel stops is easy enough. | ||

EricZ, "a somewhat limited project?" I was just refuring to the top speed. like you mentioned. It's limited by the gears, but I'm sure the setup will scream past 150 if the mechanics of the motor were meant for it. Like a 6 speed tranny wouldnt hurt for this kinda project but I havent seen one for xb's yet. that's the limited aspect. But since I dont know anyone that makes a turbo for xb's is you, that is kinda limited for me too. I'm sure you could think of something that will compensate for it judging by the almost factory look of your turbo setup. Great work again BTW. and the exhaust noise isnt bad, I just got tired of the blow-off screech on my car after a while, and driving with the windows down in the car was pretty annoying. now that I look the purge valve is located on the bottom where the muffler used to be? This way everyone else can hear it loud and you can ride comfortabley? (Message edited by clutchless on January 03, 2008) | ||

Hey Ericz is that the same bike with a new swingarm, or a new bike? | ||
| No_rice |
its the same bike with a new swingarm | ||
| No_rice |
only problem is he is going to have to redo things for an xb9. the map wont be the same and i have no idea if what he has done about injectors will work either. | ||
| Barker |
oh crap, completely forgot the whole 9/12 thing. I can get bigger injectors and higher pressure fuell pumps, no problem. It just need a map. Or a dyno and the 12 turbo map. TAKE 2,,, Ericz, Keep me in the loop. I want a kit for a XB9. Let me know about pricing and availability if you ever go that direction. But I might just upgrade to the 12 lump in my NineR. That way i have the cheaper ins. (Message edited by barker on January 03, 2008) | ||

I'd be interested. Be nice to have a turbo Uly. I would need the exhaust to run out lower though. How much does the turbo stick out? Got any pictures from the back or top rear? 3-5 fill ups per mister fill seems pretty good. What does the dyno look like? | ||
| Blake |
Folks selling stuff here typically need to be sponsors. Let's please avoid putting Eric in a position of running afoul of that policy. Thanks. | ||
| Ericz |
Thanks Blake. I am not going to advertise anything on Badweb until it becomes a reality and my business becomes a sponsor. I am happy to answer questions about the current setup. Here is a picture of the front and back:   The new design I am working on relocates the turbo to the front bottom of the motor, right behind the front wheel. That will keep all of the heat and noise away from me and it allows for a shorter distance for the exhaust to travel from cyl head to turbo. The new design will have a larger volume on the intake side between the turbo and cyl heads which will make for even better off throttle response and will extend the life of the turbocharger's thrust bearing. The new turbo placement will also improve weight distribution. The left side setup is not noticeable but having the weight of the turbo more centered and lower will go more with the whole "mass centralization" thing. Here is a link to my dyno chart I posted here on Badweb: http://www.badweatherbikers.com/buell/messages/384 2/220474.html?1160621768 | ||
