Hey guys been working with One Off Customs on a turbo Idea.
So far we are gathering parts and planning this out.

I will be posting pics and updates as time goes on with an eventual dyno run.

heres is my bike currently.

selected a turbo for the bike

and just received my power commander and exhaust gaskets

still waiting on a few parts before we dig into the bike. (boost gauge, turbo flanges and gaskets, and air filter)

had some sweet flanges show up today

started tearing into it today.

making a custom exhaust is going to be fun.
harleys stock exhaust has a flare on it and made the exhaust guy get a little creative

Pics didn't show up on my end... But ****, you actually went through with it... If I could see the pics I would give some input... and of course keep me posted as I would do the Turbo kit myself, but I don't do autocad or 3d printing, I am a caveman welder, auto mech with degree and certs, but that only goes so far...

injector swap is probably gonna be mandatory, pump maybe, compressor bypass/blow off valve, internal wastegate I assume, turbo oil feed line, and coolant lines if you are tapping those as well, refuel map and tune for 93 octane at least (turbos hate detonation and exhaust back pressure), exhaust will be fun to create some bends... Stainless or mild steel for the manifold? and what turbo did you guys decide on?

How ever I've switched it all over to photo bucket pictures.

I can tell you that they survived a pressure washer with out letting water in lol.
But i had to pick up plugs from my local hardware store to plug up the holes in the bottom. They must have used those holes for a different mounting point.

I like this mod for the 750. Somehow, eveything on this motor screams "Feed Me!" Let us know how it progresses. I'm working on suspension mods ar this point, before I pump any more H.P. Changing wheels so I can run a 120/70/17 on the front, and a 190/50/17 on the rear. Also changing over to chain drive. When that's done, I'll be ready to handle more get-up-and-go.

NICE! i look forward to see pics! 190 series rear!? Thats a big jump over the 140 series. Going for looks or drag racing? lol

Also you might want to think about a brake upgrade.

side note, why a chain drive? looking at changing gearing?

Hated the 15" rear tire since it was new. It's profile is too flat for good road handling. They used that size because it's light, cheap. and gives better "urban experience" with the stock final drive ratio. The skinny front is just to give the Street series the flick ability for city usage. I wanted some thing more like you find on other touring bikes (R1200RT, etc.) Get's the back end up a bit and improves lean angle. Also, a lot more options on tire replacements, and longer tire life. The right compound in the sizes I'm working with should go for up to 15,000 miles.

Already got Brembo's front and rear. That was one of the first changes I made. And I replaced the front brake line with braided for more rigidity. Wheel change gave me the option to go 2 discs on the front, but decided that I don't really ride it that hard, so I stayed with one. Am also changing the forks. Found a basket case Buell with some really neat forks. Just need the bucks.

Chain is to have more options on gear changes. With the larger rear wheel it changed the overall ratio, and without a turbo, it's a dog off the line. If your turbo works out then I'll probably go that route (when $$$ is available). That will give me the low and mid range, without increasing cc's, and still have a good road bike. I love the belt drive for smoothness, quiet, and lack of chain maintenance, but you're limited on belt size, and pulleys. With chain I can make it any size I want, and there are an almost unlimited options on sprockets. That's the trade off. Check out Chapelle Customs bikes, the factory flat trackers, and any of V & H's drag bikes. All chain.

Pics in the first post don't work for me either. They didn't in the second post, but do now, so whatever you changed is good.

GOOD! brembos are a huge upgrade over the stock ones! I'm using the 4 pot Nissin off an F4i/CBR600.
So much better!!

Hmm chain drive may not be a bad idea now that i'll probably have the power of an SV650 or Hyosung GT650R. Lower the gearing for better highway gearing, doubt it will adversely effect my MPG.

Which buell front end are you going to use? xb9?

I actually just bought a set of OEM wheel with brand new tires from Chapelle for $260 shipped to my door! seems like a great company to deal with.

Clean those welds up lol... looks like ARC welding to me... mild steel of course MIG and ARC are great for, but I prefer TIG if I can... I figured that's where the turbo is going... Be sure to make a manifold setup for a bolt on kit, I can do everything myself except the pipe bending, or mandrel bending whatever you guys are using... Looking good Adam and Nick... Great job guys, not get the ball moving on the 2016+ Brake caliper brackets so I can upgrade my shitty so called 300mm big brake kit from Harley...
