TTS in the UK has a supercharged Rocket 3 kit, and even one for the 'Busa. 226rwhp/200ft-lb of torque anyone?

The kits use a Rotrex supercharger that is a belt driven turbo compressor with a planetary gear/ball drive to step up the rpm. This SC is almost silent from drive noise. It would make for a very compact kit on a Speed Triple.

Something to think about (IF I wasn't already working on a similar kit). :wink:

Ummm, no. They require no power from the crank to drive, but also kill any type of chamber scavenging. The peak adiabatic efficiency of most turbocharger compressors is well under 80% (some well under 75%). AND the compressor has heat translation from the turbine side of the unit.

What if I told you there is a type of supercharger/compressor that is better than 90% adiabatic efficient, takes 10 hp to make 10 psi, and COMPLETELY vaporizes fuel in the compressor so that even on gas/petrol the discharge temps are below freezing? This requires NO charge cooling. On alcohols (methanol/ethanol/E85) it is absolutely amazing! It is also very light.

It's coming!

If boost is tied to rpm, then power is easier to modulate with the throttle - unlike a turbo. This makes a shorter wheelbase bike much easier to control and driveability is not altered at lower rpm/cruise. But 50-100% more power will require restraint. :cool:

I need to order a parachute and an airbag suit!! Jesus , when can we hook this dude up??
Think it will top 200mph at Maxton (need a fairing?)

Well I've never heard of that before!!! Sounds pretty f'n sweet. I was talking conventional turbo's and supers. Turbo's are more efficient, produce less heat than supers, and are much easier to adjust power with (up boost wt control vs. changing out pulleys).

Trust me, I really like turbos. But there are trade-offs with all forms of forced induction. The main problem I have with turbos is the lack of new compressor technology. In many cases, the same 40 year old compressor wheel is given a new name with only a .010 change to the backside clearance, and everyone thinks there is a new compressor on the market.

Even the BRAND NEW (last couple of weeks) inducer technology from Turbonetics is old school info. It is just new to most turbo users. Turbonetics NEW stuff

LINKS TO INFO PLEASE! :hammer: :hammer:

i REALLY want to like superchargers...

the turbo's that would work great for the bike are the ones from aeroturbine. It's an internal oil cooled turbo so there's no need to run oil lines. It spools almost instantly, the only downside is that they only can hold about 8-10psi before they've reached their limit. 8-10psi on a bike is more than enough. They also have kits for cars, but they top out at around 230whp on 4 cyclinder 2.0L.

I posted this in the Rocket forum last summer. My dealer built this and I took the pics at our Triumph track day:








Link:
Echo Cycle in Edmonton

Custom designed one of a kind low compression JE forged turbo pistons with full floating pins. Custom designed H Beam Carrillo conrods. Cylinder liners and Head O ringed. Custom copper head gasket. Custom clutch work. Custom hand built tuned length mandrel bent turbo manifold. Garrett T04 Hybrid water & oil cooled turbo. JGS external wastegate. 2,1/2 inch wide open exhaust (Yes the turbo whine even at idle sends chills up your spine), JGS Blow off valve. Custom Air to Air Intercooler with Custom C02 spray bar. Custom hand built polished Inlet plenum with 3 additional Injectors fed by a 5/8 custom fuel rail. High Flow EFI Bosch fuel pump. Bosch EFI rising fuel pressure regulator. Ignition controllers w/boost retard, Secondary injector controller w/ boost sensitive control. PC3 Powercommander for first stage injector control. All laptop programmable, which is done in store on our DYNO.

Rear Wheel HP @ 16 psi boost: 335 hp @ 6500 rpm on pump gas (300% increase in hp over stock)

Rear Wheel Torque @ 16 psi 302 ft @ 5300 rpm on pump gas (300% increase in torque over stock)
(Wait till we fill it with race gas and turn the boost control up......)

This custom turbo Rocket makes more hp @ 3700 RPM then the stock Rocket 3 makes at redline! (6500 rpm)

To put this in kind of power into prospective, lets take the new Ford V8 GT Mustang which makes around 230 hp at the wheels, and around 250 ft of torque at the wheels……. Now take another 100+hp and add it to the wheels, and then take another 50+ ft of torque and add that to the wheels, now shred over 3000lbs of weight, hmm.... mind boggling isn't it!



Even with all the above modifications the bike starts and idles smooth like a stock Rocket 3, and still gets over 50 miles to the gallon. The owner of this motorcycle still uses this bike to get bread and milk in the morning, and takes it in all the local toy runs and rallies..... but when push comes to shove and you roll the throttle on and bring the engine above 3000 rpm, that's when this animal comes alive, the ear piercing whine from the Garrett T04 turbo spooling up to over 100,000 rpm cramming 16 pounds of boost into the intake plenum and the fury of a 2300cc (141ci) pouring out of a 2,1/2 inch wide open exhaust lets loose and has NO mercy for the rider or anything in its path, smoking and tearing the 240mm rear tire apart at any speed, the insane G force trying to drag you into the future as your eye balls sink deep into there sockets trying to exit out the back of your head, while you hold on for your life as telephone polls blast by like a picket fence, you now know what a cannon ball feels like when it leaves the cannon! After running out of gears at redline in top gear at around 180 mph (290 kmh) you roll off the throttle and the loud blast from the blow off valve releases the intake boost, your mind starts to catch up with the earth again and you realize you are still alive, a smile stretches from ear to ear which couldn't be slapped off your face if you tried, and all you can think about is how incredibly fun this motorcycle is!

During testing at the drag strip, the bike has sent the front wheel sky high at over 130mph (190 kmh), I guess you could say this bike is not for the faint hearted! The bike has run 9 second passes during this season with ease, this is with a stock rear street tire and no wheelie bar. There will be no problem taking this bike into the mid to low 8's next season!

Bike built, tuned and DYNO’d by Echo Cycle.

You dream it, we build it!
