I apologize for the lack of updates lately; I've been going through some major changes in my personal life and could not find the time to post everything. However, I have time tonight, so I will bring you all up to date...


Here's the completed exhaust...



That's an O2 bung for the wideband datalogger. Not pictured here are the tabs that were later welded onto the top that mount the muffler in the same spot as the stock cat. The 4-way split inlet is a snug fit onto the header and, once clamped, everything seals up rather nicely. I played with the finish of the stainless and decided to leave it brushed for that no-nonsense works look.





Everything prepped and ready to bolt onto the bike. That's kevlar-lined thermal shielding and it reflects an extreme amount of heat. I actually had to buy a special pair of scissors just to cut the stuff.





Mounted on the bike. So far, so good...





Crank pulley mounted and belt installed.






Intake tubing in place, BOV mounted, and airbox firmly secured onto the throttle body. The Rotrex canister will go in the empty space on the right. The BOV vacuum reference is sourced from one of the big ISC lines on the front of the TB, since all the other ports are restricted and would not operate the BOV properly.





Here's how the inlet tube and filter is set up. The filter gets fresh, cool air directly from the ram air port, and the filter clears both the steering and the bodywork once mounted. Thermal barrier abounds everywhere, so despite the incoming air running directly behind the header, it should stay relatively cool across that short distance.





The radiator has been spaced out up top and the inlet hose has been spliced with an extension elbow to work around the supercharger.





Priming the Rotrex oiling system. There is a custom curved oil cooler mounted at the top of the radiator to help cool the traction fluid -- Rotrex superchargers do not like it when the fluid gets hotter than 180ºF, so the cooler ensures that does not happen. You can also make out how the exhaust fits on the bike with the O2 sensor mounted up.





The Rotrex oil canister mounted up. Thankfully there is plenty of room under the tank to clear these components.



Now, at this point you might be wondering if it all worked out...



...and that is a story for another day (when I can get some time to edit video)...

Bloody brilliant :)
Have you checked inlet temps yet to see if there is much rise ??
With the bolt together plenum you have now it would be relatively easy to redesign to include a heat exchanger core clamped within the halves

Thanks guys. Since I only plan on running 9-10psi peak, I'm not worried about an intercooler. The time and expense that goes into designing an air-to-water system just wouldn't be worth it. If I feel I need extra protection, I'll add a water/meth-injection setup or run better gas. I don't do top speed runs, so this engine should handle my style of riding and 9-10psi just fine.

Is the stock header with the SET going to get trashed? I would have to think with a motor breathing as heavily as this you wouldn't want to stick with the stock headers.

The stock header should be fine for all intents and purposes. I've left the SET valve in there, but have it fully open. Since the Rotrex doesn't provide tons of power down low, the smaller tubes of the stock header will certainly help keep a snappy feel with the higher velocity of the exhaust gases. Besides, the stocker is not too shabby when it comes to power. Take a look at this dyno chart -- the green line is a full Leo Vince system, and the red line is the stock header with slip-ons. There's only a 5hp difference up top. The purple line is with MR9 race gas, btw.
