Hope santa has a BIG WALLET.
I like turbocharging, heck, I'm a turbo guy but on diesels. For a lot less bucks and I mean a LOT LESS, you could put a set of 3 fogger nozzles in the intakes and a bottle of Nitrous Oxide on a frame tube. All the electronics are already on the bike and while the horsepower and torque gains won't be quite as sensational, considering what the R3 makes stock, the addition of 100 or so horses would put the bike and the end of the spectrum for a mere mortal man. Besides, look at the internal mods on the engine. Carrillo rods, new head gasket (I bet thicker), "O" ringed sleeves and head, custom pistons, heavy duty clutch. Nothing mentioned about the final drive and that's odd. Don't matter. The custom machine work alone would be a couple grand and a Garrett oil/water T40 is a grand alone. Add in the aluminum fab work and the the custom intake and exhaust and I'll bet you double the price of the R3.
I'd be afraid to ride that Echo setup or the TTS unit. A second of inattention or sudden wrist spasm could send you to the hospital or the morgue.
With those modifications you have taken the street bike and turned it into a strip bike. I know the article says the owner takes it to get milk and bread.....yeah, right. That bike is about as tractible as Ms. Budweiser is to a canoe.
It's a nice "dream" bike, but for 99% of us, it's just that.
If, per chance anyone here does decide to build a TTS or Echo machine, I'd like to take it for a spin. 1320 feet would do nicely.

You can hold my R3 as an insurance deposit in case I destroy your bike.
