Buell Engine Performance Mods?

[LeFox]

13psi boost should give you 120hp(easy) on a xb9, when set-up correctly

 

[mrdozer2you]

That sounds perfect [up]

You have got me rethinking my whole system of beliefs.So basicaly your saying maybe with little modifacation,except the turbo and a lower compression ratio,you could gain +/- 40% power increase? Is this cost efective versus just increasing displacement and the usual mods.to acomplish the same goal? In other words,best bang for the buck.Also has anybody rode a turbo bike before? would it be reliable? Run well on pump gas?One last question,can the whine of a turbo, no matter how powerfull, invoke the same emotional response as the roar of a big Harly?

Pump gas: yes, 93 octane
Bang for the buck: maybe, depending on how much of your own wrenching you do.
emotional response to turbo whine: I like it, plus you still have the Harley roar at idle and low or no boost conditions (boost whine is only there when accellerating)

just my $.02

i'm no talking howlong your engine will last, but considering the powergain, i think the turbo would be cheaper.

Also has anybody rode a turbo bike before?

yep...watch the throttle, cause you'll see nothing but air!

Run well on pump gas?

why wouldn't it, it just pumps more air into the engine.

One last question,can the whine of a turbo, no matter how powerfull, invoke the same emotional response as the roar of a big Harly?

look & listen to this and tell me what you think!

Damn I can't wait until my warranty runs out![cool]

 

[Das Bolt]

That was impressive!Looks like I will have to give this some real thought.

 

[BuellPastor]

Wow. That is incredible.

 

[mnbuellman]

ok so tell us were do we get this kit or have this done at?

thanks

 

[Das Bolt]

Hillbilly motors has some nice stuff but most of the web site seemed to be in german,look at the gallery if you check them out some real nice bikes there.

 

[LeFox]

will have a look if i can find some in the u.s.

 

[mnbuellman]

Hey his and hers- Is that your bike? Lefox any luck?

 

[His_and_Her_Buells]

Hey his and hers- Is that your bike?

I wish! Mine's all stock except for a Special Ops pipe. I've got 4 years of warranty to wait out until I do anything major like a turbo. But it will happen eventually

 

[LeFox]

Lefox any luck?

i got some links...

[Das Bolt]

Thank's LeFox,you realy have a knack for finding links.The best I found was called mr.turbo,they seemed to mostly work with Kawasaki though.I checked out your links,looks like 130HP is about average before you get past the point of reliability,past that they talked about water injection and race fuel mixes.Now ,I understand you can make the the same power with a turbo 900CC as a 1400CC f.i. motor but is it the best way to go?I haven't priced it out yet but a big bore kit from zipper's performance seems more practical,if less unique.The price of the turbo kits looked like about $4000. on average without engine work,if I can get performance/price info from zipper's I'll post it.

I sent an email to Hillybilly motors and here is the response I got.

Dear Eric,

my staff quote me your e-Mail about the Turbokit.

Turbo or Supercharger is one of the things I still do personal. In the past all Kits I builded were one of a kind, customized what the customer like to do with it. From show to race.

We are in a discussion to build an XB Turbokit in an issue of 10 or 25 units this winter.

If we do that, the launch of the Kit will be on the Fighterama Bikefair at begin of November. The Price will be around 5000 US$ as a bolt on assembly.

The Kit will be able to deliver 0,8 bar pressure and comes with a overpressurevalve what will open at 0,3 bar. That means you can use it with the original Compressionratio. The increase of HP will be that way not more than 10 HP but there will be no extra enginemodifications nessecary. The enginelifetime will not go down. For show and a bit Tuning this is a good solution.

If you like the full power, with rising the pressure the HP rise, but there you come quickly to point were you have to build up a real turboengine wit low compression pistons etc.

Best regards

As cool as it looks I'd for that kind of money send the motor to Brian Nallin at Revolution Performance or Terry Parsley in California for there cam's a 1250 kit slight head work and Direct Link system let them tune it. It would be a solid turn key reliable package and net you 105-110 tire HP. And you'd have alot less in expense.

 

[LeFox]

but no whistle

 

[zombieBUELLer]

just add one of these .. problem solved!

 

[mnbuellman]

I say its only money!
