I made the Crankenstein video. I walked up to Randy Muchmore an hr before the big run and asked him how much hp does it have.. His exact words............... well at 175 hp the rear tires start to haze. We can't strap it down any tighter so that's all the traction we can get.. It's a 670 Rotax bored and stroked to a 750.. Kind of off the subject, but that's my story and I'm stickin to it..
The good builders advertise, the great one's don't need to........

All you guys are talking about turboin' a Banshee, well Ive never seen one and Im not sure it can even be done, seeing that its a 2-stroke. Because, at one point, during the 2-stroke cycle when the piston is at BDC and the intake port and the exhaust port are exposed creating 0psi. If anything, a turbo would just waste more fuel by blowing it straight through the cylinder never even burning it.
Ok go ahead and shoot me down. Let me hear something good.
Got a good buddy that owns a company about 1/4 mile down the road that has owned a turbo Banshee for a few years. He doesnt bring it out very often (probably because something is always going haywire with it) but when it runs it runs very hard. It is fuel injected with the injectors being mounted where the boost bottle would go. It's insane to see the guy at Little Sahara ride a power wheelie with a +14 swinger for 300-400 feet.

What does one of those nice triples run for hp with a fairly aggressive build?
Posted by: DaBeechMan
200

careful with what you say yzf, there is a lot of stuff being built that you couldnt even imagine being possible.
Posted by: DaBeechMan
if that banshee only made 40hp both him and your techs need to do a little tuning. Not too sure why he would have a twister crank coupled with a mild port and with t-5s and pj carbs. It doesnt make any sense why he would dump a ton of cash into a crank only to build mildly around it.
Ive also never heard of a 200hp turbo banshee, other then dans monoblock turbo that killed itself. Highest other then that was 186 or so and his dyno reads high.
Sandgod, my cranker blows the tires at 130

just because you dont see it doesnt mean it doesnt exist. There is also a turbo honda putting down 150hp at 16lbs of boost. But since you cant see that im sure you dont believe it either...

there are a lot of billet cased banshee motors out there right now.
Posted by: DaBeechMan
a superflow is about 12% on older dynojets, but only 6% on new dyno jets
really though its pointless to compare superflow numbers because you can put in ANY correction factor that you want.

1st off I guess it depends what you consider "Big HP"

cases and cyls

Porting is the main thing to gain a lot of power on a 2-stroke. You need intake(air filter/air box) and exhaust mods to go with it.

Does Ohton put out a good motor to compete these days???
Posted by: XR650Warrior
He's had one of my buddies motors for 2 1/2 years now, still waiting for the results

"big hp" is definately a relative term. to some people, adding 10-20 hp is big. i've caught wind of a 230hp banshee w/o nitrous or turbo or super charger...
Posted by: CroBiker
i think it's basically a crazy a$$ crankenstein. the cases might be stock...

ahh the mythical trinity claimed dyno numbers. Trinity's dynos are so off i'm surprised they dont try to run the dyno pulls on the front wheels.... Trinity is a myth, their dyno numbers always seem to come off WAY different on other dynos, not saying they dont build fast bikes and make bike numbers cuz they do, just saying put that 248 hp 'shee on any other dyno you wont see that number. On the turbo subject now, you can turbo any motor on the earth basically. KMS has a snomobile puffing around 345hp with the Garret and the NOS. He has a raptor up to 150hp with the tubo, and 180hp while pressing the "go baby go" button" As far as dyno's go dont judge them, they are a TOOL(not a toy) for reading air/fuel and getting some baseline runs. Certain bikes makes some goofy A$$ numbers on the dyno and still scream. Rapfam730 on the same dyno makes almost teh same horsepower as my little stocker, but me in a race with him, ill eat sand the whole way up. Why? A dyno isnt goign to say which bike is faster, and who is going to win. the 40hp 'shee that was supposibly "built" i bet it didnt ride like a 37-40hp banshee. (figured i would give this post a little fire... )
Posted by: CTracingraptor
Like i Said a dyno is a tool and not meant for bragging. Peak is different than overall. If that 248hp shee holds its big power number for 2k rpms its will kill. but if its peak and comes on so fast and drops off jsut as quickly what good is it doing you....none

a quick gain for HP is shave the head, pipe it, port it, and get new filter.....

230 hp? turbo cbr1000's only make about 295hp, it cant be the normal 350 engine modded, had to have a bike or sled engine in it.........

i was just about to post that trinity banshee. That thing is INSANE!
Posted by: sandman99ex
how do people get so much power out of the banshees how much money do they put in them and what are some cheaper ways to get some pretty big hp numbers out of a banshee
Posted by: yzfpilot
be careful of peoples "claimed HP" numbers. They are mostly bogus. We have a Factory Pro Dyno, and our lead tech is building a 2005 Banshee and are dyno tuning it very carefully. So far we have gone with a Welded Crank, Porting, head mod, bored the carbs, Toomey T5's K&N Pro Flow in stock Airbox, and have arrived at 60 HP.... Then we changed our Fuel/Oil to Maxima 927 and Trick 110 mixed at 20:1, jetted it on the dyno, and were able to make a 65 HP run. That's true rear wheel HP. A Dyno Jet Dyno would probably measure it at well over 70 HP. That's a fast Banshee for a mild build. If anyone tells you they have a 230HP Banshee that's normally aspirated, they are yanking your chain.
Posted by: yzfpilot
I am very careful about what I say....... If you read my post I said "naturally aspirated" Our head performance tech built a 200 HP banshee...... complete with a nice handy little Turbo charger. I know in this day and age that there are unlimited possibilities, but my original point was that most people grossly exagerate HP numbers "My sano trick bitchin banshee was ported by Joe Blow and he turbo'd the crank, bored the carbs, 4mm stroker..etc...is putting out 150 HP" is usually bs. real true numbers are hard to come by is all I was warning. We had a customer come into the shop recently with a beautiful banshee. Mildly built, it was supposedly ported, had a twister crank, Keihin PJ carbs, cool head, custom domes, ignition advance plate, T5's etc.... a healthy chunk of change put into it. Bottom line on the dyno..... 40HP..... The person that built this bike for him I'm sure promised much more than it turned out to be. Be careful what you pay for. The nice thing about having a good Dyno, and a very experienced tech is arriving at good combinations to achieve some true - usable HP numbers. Were playing with Cheetah Cub cylinders now and should be getting some good results. We're not breaking new ground here, but like I said earlier, we're not promising our customers BS dyno numbers.
So back to what I said originally, before you jump at anyones performance promises, and trust their Dyno numbers, do some reasearch, call around, and talk to as many different sources as you can. Get a feel for the shop you're considering. Sure big HP in a banshee is possible, ( people have been doing it for years) but be careful buying into things before you give it a considerable amount of research.

I'll post some pictures of the turbo charged banshee. I'm not saying it's the hot ticket, but our performance tech certainly built one, and this is a man that doesn't exagerate HP numbers. As for that 40 HP banshee.... We didn't build it. In fact, the customer brought it to us to dyno tune the carbs, and upon the first sweep, it was only putting out around 36 HP. Not really impressive. We tuned the jetting, experimented with ignition timing, and ended up at around 40 HP at the rear wheels. Still nothing to write home about. My whole point about that Banshee is that there are tuners ( or so called tuners ) around the country that are making some pretty big claims, and even using good components ( twister crank, etc..) but if the porting, head work, piston choice, jetting, and work in general isn't a very well thought out coordinated build, your motor is only going to be as fast or strong as it's weakest link. In this bikes case we believe the porting just wasn't what it should have been in combonation with everything else done to the bike. Little details really matter, as do working with a builder that is realistic. We regularly have customers that think a stock banshee motor puts out 50 HP because some sales person, buddy of theirs, ets said so etc. We get people EVERY day that just can't believe a stock banshee puts less than 30 HP to the rear wheels, or that a Raptor 660 in stock trim tips the dyno at around 27 HP. That in mind, when we build a 70 or 80 HP banshee without getting extreme, and still being reliable, it's a substantial gain. 100 HP plus is definitly possible, but not without forking over some serious cash, or adding a magic button ( Nitrous). I'm not the one building these bikes, but I help facilitate it. The credit goes to our performance techs. 200 HP Banshee? Sure, if you add a Cylinder, Turbo, Nitrous or have some new trick up your sleeve we haven't heard about ( 535 Cheetah cylinders is a good start, but I still don't see that breaking the 200 HP barrier without something like Nitrous, Alcohol, etc. and how reliable could that be.)

i think dasa has a billet case for a 20mil stroker crank and they set up rex cyls for it in 75 mil bore if anything with 2 cylinders and still almost looks like a shee motor could pull 200 horse id say thats it(and inb response to the turbo yes there are turbo shees and yes u waste a lot of gas but yes it goes realy fast.
Posted by: WesternHighPerformance
there are many differnet dyno,s and many different brands dyno jet = true horsepower +10-12%. superflow are much better closer to the truth but unless you spent 1.5 million on your dyno cell im sorry to tell you you dont have a clue what kind of power you r realy putting down however you can tell if what you did makes it better or worse. and as a side note an y backyard idiot can make big peak numbers its the overall power that matters just caude you peak at 55 ponies dont mean your going to beat a 45 hp bike if it holds its power over twice the rpm range and is easier to controll(and waht trinity builds for us is alot different than what it builds for itself)
Posted by: WesternHighPerformance
yah there are to many twisted dyno operators out there and ive never understood why they correct for altitude just a way to make there numbers look bigger
