SUBSCRIBED!!!!!!!!!!!!

 

I hope you've upgraded your clutch already! If not, that supercharger won't do anything but make a bunch of weird smells come out of your clutch basket... :laugh:
Good luck.

 

Dont forget diapers for the weird smells most likely to come out of his own backside.

 

yeah, I have a heavy duty Barnett plate and spring kit.
The bike will be running in a couple of weeks, we'll see how it holds up. might need to have some extra heavy springs made.

 

Go for it. This should be interesting. Someone not so long ago did a turbo Daytona and took lots of heat from other "experts". I wish you all the best.

 

Yeah many have tried turbo mods. One guy recently got it. Good luck to you. You might find his thread to be some sort of help. I believe he ran a fuel pump from a wrx.

 

Fuck yeah buddy. Keep the pics coming and good luck keeping the front tire on the ground!!!

 

watching :thumbup:

 

In. :thumbup:

 

Double In:thumbup:

 

This is gonna be sick!

The 675 already has that unbelievably nice whine sound. This is even gonna make it whine louder!

Kudos to you man.

 

I was thinking the same thing, but I'm not sure how this one is going to sound because it's pretty much a belt driven turbo charger. It's completely different than the setup found on most supercharged vehicles. We'll see though...

Wow. Nice.

 

Good luck.

 

This should be a fun project. Good luck, and pay attention to the details.


You will have a bit of an issue with MAP since the stock sensor will not like the higher pressures you want to run.

We've done a few Rotrex/TTS kits on Rocket IIIs, and the map that comes with the kit is useless. I suggest using TuneECU or TuneEdit and adding a PC5/multifunction hub and pressure input harness (3bar GM MAP sensor) - part number 76950325. This will significantly help get smooth transitions at the on/off boost transition. Expect to spend a good number of hours on the dyno mapping part throttle fuel and ignition.

You are also going to want to add a boost referenced fuel pressure regulator. An upgraded fuel pump is a good idea as well.

I would also highly recommend some form of active knock system. We use some custom made units that detect knock, in which cylinder(s) it is occurring, and only pulls ignition advance in the specific cylinders - within 12 revolutions. Then the unit continuously attempts to add the advance back in - starting as soon as 20 revolutions later.

The units we use can be switched between 3 and 4 cylinder settings, as well as how much total advance is pulled, and how quickly advance is pulled. There is even an option for a display to see when the unit is pulling advance, and how much. This is CHEAP insurance against bad fuel and atmospheric changes.

If there is anything we can do to help, or any advice I can give, please don't hesitate to contact me.

 

GOOD LUCK!!! Subscribed!

 

We need regular updates and u cant do any other work, apart from on the bike !!!
Plus we need loads of pictures......

 

+1. Subscribed. Can't wait to see how it comes out.

 

Awesome, Awesome project.

I was considering the possibility of adding a centrifugal supercharger to the D675, but I wondered where you could tap power from.

I have a Procharger centrifugal blower on my Mustang Cobra, and it makes a noise very similar to the engine whine on the D675.

Centrifugal blowers, make boost in direct proportion to engine RPM which is perfect for a high revving motorcycle engine. Unlike a roots or twin screw blower that makes peak boost at low RPM and holds it constant across the powerband, dropping off at higher RPM.

There was another guy who was doing a turbo build for his bike, but couldn't find higher flow injectors. But he found out that the bike takes a standard fuel pump similar to a subaru WRX, which is the same as lots of different cars, which can be easily upgraded to a higher flowing unit such as a Walbro 255 LPH pump.

Are you going to use an intercooler? Centrifugal blowers don't make quite as much heat as a turbo, so it's not as critical. But you could use meth injection instead. That's more easily packaged.

Anyways, can't wait to see more progress!

Theres no room for an intercooler, the bike is to compact. If I didn't have to move the radiator forward about 2" then maybe. It'll still produce some heat but hopefully not to much . I am considering a water injection system, but I want to see how its gonna run without it first. If I do ill probably run water cuz its Free!:cheers: and it absorbs more heat than meth. I'm hoping to have the custom mounting plate for the Rotrex some time next week, so ill have some new pix up ASAP!

 

Thanks for the suggestions!

who makes that Knock Detector and how much would it run me?

This isn't just knock detection, it is active knock control. The units are made by J&S Electronics. We have them made specifically for 3 and 4 cylinder bikes, and keep several on the shelf.

You will have to PM or email me for options and pricing.

 

Well my morning just started off pretty exciting!

 

i am happy to say this is the very first thread subscription i have ever done.

 

The need for engine cooling is not as large as some would imagine. Yes, a good coolant mix will be required, but nothing special.

For instance, the Rotrex kits for the Rocket III use the stock radiator, and make considerably more power than stock. Some well over 300 hp - without an oil cooler.

Look at the radiator for the later Hayabusas. It isn't that much larger than the D675 unit. Yet is more than capable of handling considerably higher output levels.

The issue will be the temp of the intake charge -vs- the octane requirement.

Also realize that you will need to find a location to mount the drive fluid reservoir/cooler for the Rotrex unit. I have the dimensions and photos at the shop should you need them.

If you are going to add a drive pulley to the crankshaft, you will need to make sure you drill/tap the center of the crank perfectly centered. Then you will need an extension and pulley to extend out of the cover, and be well sealed.

All are issues you need to consider. I hope this helps.

 

If I ran water injection that should help with the intake charge considerably, the only issue with the Daytona is theres really not much room to mount a reservoir for the W.I.S , maybe under the rear seat next to my custom exhaust. The crank shaft comes from the factory already drilled and taped (M8) and I had a shaft made for the pulley. All im waiting for now is the billet side cover/Rotrex mount. I hope to have it running by the end of the month!

Bump.....WE DEMAND UPDATES!!!!

 

:iagree::iagree:

 

They are a lot easier to map than the turbo as you can do it straight off TPS with no need for a MAP sensor for boost control.

I fitted my Rotrex on the left side of the bike just above the front sprocket on one of my 1050 SP3 bikes.

I'm very close to doing a D675 turbo Aerocharger kit and I'm using a similar type of plenum/intercooler as the one fitted on Bling Bling my turbo Speed Triple, if you would like one of the intercoolers for your project let me know.

The fan kicks in at idle and turns of at 2000rpm and the cooler is very efficient.

Boosted bikes are great fun to ride if they are done properly either on the road or race track.
With mild boost you will have a very tractable motor with reliability, 5 PSI on STD comp and cam timing moved to reduce the overlap will open your eyes. Try that first before you go to big, fitting two head gaskets to lower the comp is not ideal and can set you backwards in performance as the squish is almost lost.

Keep up the good work. :cool2:

 

Have to say that is some sexy carbon fiber.:notworthy:
