Turbo build!!!

[moodyvalk]

             
                   Moody, From the first look on psychobike that is what I liked. The slam bam in the face look. As far as the
            exhaust note, here in Ga. not a problem. This baby will sound like music at rpms compared to the straight pipe HD guys.
            In your video when you fire her up, sounds stock, not the loping idle of the blower bikes.

                   IMO you have created one awesome variation of a Valkyrie. Makes me wonder what Joe Boyd would think
            about your mod. Hope the owner will make a video of her on the road. I have enjoyed all of your post.

Thanks so much!  If it wasn't in the 20's this week i would have videos on the road with it...crazy how it was in the 70's last week, dang Kansas weather...

i could build which would be installed turn key and go setup with probably around 4500-6000 depending on how many turbos and what quality of parts.  Of course you could save a lot of money and run a journal bearing turbo or a used turbo but I don't like going cheap on stuff like that especially if its gona have my name on it when it's done....

and I forgot to mention that with a blow through turbo you don't loose that nice factory part throttle drivability like you do with a draw through setup (that's how supercharger kits are).  And another great point worth mentioning is the fact that under unboosted driving such as cruising in town or highway your fuel mileage shouldn't change from where it was at prior to turbo.  this should go without saying but I will say it anyways, the more you boost the more fuel you will use.  more horsepower is more air plus more fuel....

My part throttle performance is quite good. It sure wasn't when I purchased the bike (with the blower already installed) as the air intake design and jetting was a mess. It's also the 2nd gen blower setup which is a good improvement over the original J-tube design. That said, the engine and blower has to be warm before things settle down to get a good smooth idle and throttle response. The throttle response is a bit touchy with the available power as it's there from idle on up. My mileage is right at 30 mpg whether it's city or highway so I'm about 17% less mileage than a stock setup. I'm running with the larger Interstate tank to get decent distance between fill ups.

What boost are you using and are you using the stock ICM and timing?

[moodyvalk]

With the right spark plugs gapped at my specs the stock ignition system will work fine for my street setups. Every bike I have nitrous injected or turbocharged have never needed an aftermarket ignition system.  This particular setup is boosting 12 psi at redline. Realistically 12 psi will not be reached very often.  I had not planned on building more than 8 psi.  In the taller gears the clutch won't hold much more than 8 psi. So we could build 20 psi and it wouldn't matter if the clutch will only hold 8 psi...a person can easily adjust the desired boost pressure via the wasegate, whether that be 4 psi or 12 psi or anything in between. No regearing  for different boost levels. Use a 4 psi wastegate and an in line mechanical wastegate controller to adjust to desired boost pressure.

A stronger clutch spring and boost ignition retard controller would be required along with possible race fuel if someone was wanting to race a valk.  As far street riding and wanting to show off a little here and there and maybe to leave a crotch rocket sitting in your dust from time to time, 91 octane, my plugs set at my specs, and proper fueling is all you need

really the only accurate way to get great throttle response on carbureted bike and to get proper fueling to each cylinder evenly is with 6 carbs...with one carb mounted a ways away from the intake valves, no way to insure proper fueling.  

im not against superchargers. I love the design of procharges!  centrifugal supercharger blow through 6 carbs would be my preferred method....but as they say, there is more than one way to skin a cat.  and one thing for sure is in common between us and that's the fact we like horsepower and living on the edge.

I forget most people that are not familiar with turbo's wouldn't know....you don't need silencers with a turbo.  the turbine wheel acts like a muffler.

nope, would never have known that. Fantastic job.

Thank you sir!  yeah actually if you were to put a muffler/silencer in conjunction with a turbo that would make one heck of a sleeper!

we want as little to no back pressure after the turbine housing, this would hurt the effeciency of the turbo.

Got about 20 hours invested in a nice laminated 16 page turbo owners manual. Also have it in digital copy in pdf format...I'm very proud of this!

[moodyvalk]

Wonder if you get this with a supercharger kit????

[Bighead]

Kinda looks weird with no exhaust running out the back

As well you should be ! Very interesting write up. I learned a lot. (Didn't know the turbo impeller acted to muffle the exhaust noise)

A trade off that is well worth the outcome! 

[dago mooserider]

Man, this turbo thread is making me foam at the mouth.... I am a full on horsepower junkie and will start saving my pennies for a turbo now.... I recently had my valk "tuned up" by attic rat and she runs so good it'd be a shame to mess with it but I may not be able to help myself.  A second valk may be the answer. Moody, think you'll still be doing turbos for the next couple years while I save up?  I definitely would want to go a more subtle approach and stash that turbo under the swing arm/behind the tranny but I do get the "in your face" style of this one. Love it.

Thanks bro! I am up for any project. We need to exchange contact info! I would like to work something out with another valk build, although I do have 2 new turbo builds next in line that are not valkyries...my current email I use is moodysuzuki@hotmail.com

[moodyvalk]

HOLY CRAP!  Tonight was the last good evening on decent weather to fine tune the carbs in before I load up the bike and head for Colorado. and I go the carbs set perfect.  I about crap myself when in 1st gear the valk as soon as it started boosting power wheelied high enough it scared me and i chopped the throttle and slammed the front end back down. I was focused on the air fuel ratio gauge so the last thing I was expecting was the front wheel to power up....and when I say wheelie, I'm talking about a serious wheelie.  As you can see from my list of bikes below, you can tell I am very familiar with the 12 o'clock position on a sportbike.

so I slowed down and started from a roll in first gear again, punched it and up the front end came again.  This time I was expecting it so I was able to ride it out for a bit.  Now I know I need a video to prove this too the internet folks, but I was too excited not to come post this.  My hands are still shaking!

wish I had time to video one, hopefully I can try too before I load the bike up tomorrow after work....

[moodyvalk]

I have the give a shoot out to the member Red Diamond for helping my out with a nice used cover! this one blow off and I just got the new one back from the pin stripper tonight just in time...

[specialdose]

                     

                                    That is what you would call " must see video " 

[Jess from VA]

Better eyeball your forks..... many tend to seep fluid even without big wheelies.

I agree,, strange looking,,  maybe some saddlebags, floorboards and aux fuel tank down under........  still makes your mouth water thinking about it.

[pancho]

Really like the professional looking manual you put together Moodyvalk,,,  shows some serious investment of your time and effort,, it adds a lot of credibility to the project.

[Skinhead]

Interesting project!   Do you have/could you post some pics of the boosted side plumbing?

I'd like to see what you did for a manifold/plenum.

Nice work.

Thanks sit and yes I have some pics, most the time those kind of pics start to bore up the tread but since ask I will show some of my secret work.  To save alot of fab time, I just modify the factory air box and converted it to a plenum...

Well I'm using my phone to post this reply and I can't seem to figure out how to post pic off phone, so that will have to wait till I get the computer setup tomorrow or Sunday in the hotel...

Could always do what a couple of the Harley bikes do; put on a fake muffler...     Hey, I could not make that up.  Google it.  Goofier than hell.

BonS - Good looking bike.  Do you know if they (anybody) are/is still making the supercharger?  A couple google searches has only turned up with some guy in Oz wanting literally stupid money.  Something like $22k AUS, or a paltry $19k US dollars.  Seriously?

You should contact Bill at magnacharger.net. They're certainly not $19k!!!

[jimmytee]

I'd be curious what the costs would be. I like the power, but not sure I wouldn't miss the aesthetics of the 6 Cobra pipes coming back. I got an e-mail back from the guy who has fabbed up a turbo kit for the F6B and it's pretty salty.

Turn key, drop it off and pick it up when it's done I think you would end up around $4500-6000 depending on the extent of the fab depending on what kind of details you would like on the build...It's $1200 for a brand new ball bearing garrett turbo so keep that in mind...

[moodyvalk]

Unveiled the Valkyrie last Saturday.  Here is the owners reaction....
in a couple of days the weather here in Colorado will warm up a little and we are going to fine tune the carbs so I'm sure we will have a few more videos...

[specialdose]

                                 So he liked it... He sounded like one of the people that just got their
                            car back from Chip Foose on Overhaulin. I know you told him all the feed back from VRCC.

[moodyvalk]

I sure did tell him the responses! And thank you everyone for your responses and opinions! It was an awesome project for me and looking forward to my next turbo build which is a 1965 Chevy C10 with a straight six engine...trying to talk Ryans dad into letting me bring his valkyrie home for a hair dryer!

BTW  Ryan asked me after his first ride of the valk, "why nobody else has a turbo valkyrie????"

[specialdose]

 
                     Moodyvalk, is Ryan a VRCC member ? I am sure folks on here would like to hear hear from him about

               his experience with his " Nasty Phat Gurl " 
                     
                     

[moodyvalk]

No he is not a member...I thought he was at first. He might register now though

[moodyvalk]

Here is a video of my conversation with Ryan while he was taking me back to the hotel.  He had no idea I was recording...this video might be boring to most but others may enjoy his animation and excitement!  

http://youtu.be/m9dqdEEjd_I

[The emperor has no clothes]

Very cool

[specialdose]

   
                      Pretty cool hearing his excitement about his new ride. Now we need on board video.

[moodyvalk]

project update...

currently adding coolant temp and voltage gauges as per Ryans request.  Will update detail pics shortly...

also added a heavy duty clutch spring to keep the clutch locked up at higher boost pressures in the taller gears.

And I'm excited to share that I am working Factorypro.com to develop a shift kit for the Valkyrie!  I have ran their shift kits on all my drag bikes and they sure quicken the shift process and makes for a quicker, more positive shift feel...  stay tuned for details

[F6BANGER]

Any new updates?

[moodyvalk]

Yes, I finally got the shift kit parts back from marc @ factorypro.com, took longer than I expected and like anything else I had to work out the bugs...also got voltmeter and water temp gauges installed and operating...now working on finishing up an intercooler setup on the valkyrie. 

Adding an intercooler to the charge tube is like adding free horsepower. The cooler the intake charge the more dense the air becomes therefore the more horsepower it will make...

[Skinhead]

Nice work.

You never posted pics (at least not that I've ssen here) of the plenum, I'm sure that will change if you are adding an intercooler.  Also I didn't go back to re-read all the posts, but did you install forged pistons?

[moodyvalk]

I will post pics of updates this evening when I get out of the shop.  If I have time and feel up to par I will post up pics of plenum. I'm feeling a little under the weather today but still trying to he productive in the shop....
