Interesting motorcycles, not XS650

The tail wrap of the frame looks kinda like an XS
Like the bobbed look of the fender too
Pondering
It's a Trackmaster Frame, they were basically the model for the 72 on Oil in Frame BSA and Triumph and very similar in many respects to the XS frame. Basic single backbone, twin down tube, twin shock frame.
A fender support loop on a XS frame would give you a very retro bratish look. While true Bates seats are pricey anymore, there are multitudes of knock off combos at the various chopper suppliers and of course e-bay. I'm building a vintage track bike based on a BSA 250 single and have purchased a similar seat combo there pretty reasonable. There's all kind of options for color and pattern of upholstery if you want to alter it some.

Confederate Hellcat, there were a few different versions that I know of and you could choose what kind of motor S&S I think. Here's Jet Li on one in the movie "War". The Chinese accents sound different for some reason though.
 
Airliners use engine bleed air (robbed from the engines) for pressurization. They feed that to an Air Cycle Machine (ACM...a glorified turbocharger) and then into the cabin. Boeing designed the 787 Dreamliner as an "electric airplane." The ACM's are electric and so look very much like this Honda contraption. By doing that, they no longer rob engine power, and they make the pressurization system much simpler... no bleed air ducting, Pressure Regulating and Shutoff Valves (PRSOV), overpressure valves, temp sensors and a whole host of other stuff... Kinda like how a turbo does.... waste gates and ducting and such. Boeing's version generates about 9lbs of pressure (boost in turbocharger parlance). When I trained on the system 10-15 yrs ago I said to myself it's only a matter of time until that tech filters down to the auto/motorcycle industry.

Honda ain't shooting in the dark here, it's already a proven technology.
 
I like the idea of the V3, but I'm not sold on electric superchargers. It takes measurable power to spin a blower, centrifugal aren't as bad as roots, so it seems like you'll still have loss from needing a stronger charging system. I think kawasaki got it right with the blower being built in on the H2, can't kill the blower from not changing its oil when it shares the engine oil.
 
here is what ChatGPT says on electric turbos:

Electric turbos are generally considered more efficient than traditional gas-driven turbos for several reasons:

  1. Immediate Response: Electric turbos, powered by an electric motor rather than exhaust gases, can spool up almost instantly, eliminating turbo lag and providing faster power delivery. This responsiveness can improve overall efficiency since the engine doesn’t need to wait for optimal boost.
  2. Independent Operation: Electric turbos can function independently of engine speed, meaning they can provide boost even at low RPMs, improving efficiency in a wider range of driving conditions. Traditional turbos need high exhaust gas flow, which typically only occurs at higher RPMs, limiting their efficiency at lower speeds.
  3. Lower Emissions: Electric turbos help reduce the load on the engine, which can improve fuel economy and lower emissions. They can also run in conjunction with hybrid systems to recover and store energy, further enhancing efficiency.
  4. Better Control: Electric turbos allow more precise control over the amount of boost, which helps the engine operate more efficiently by matching boost to demand rather than overboosting or underboosting.
  5. Cooling: Gas-driven turbos rely on exhaust gases, which generate significant heat. Electric turbos run cooler, reducing the need for extensive cooling systems and making them more efficient.
However, electric turbos require a robust electrical system (often 48V or more), which is more commonly available in modern hybrid and fully electric vehicles but not in traditional gasoline-only cars.
 
The ideahas been around for a while. You have been able to buy one off ebay or amazon for a long time, but they were really more of an intake restriction.

I remember seeing a roots style that had 3 or 4 starter motors powering it. It was supposed to work well, for about long enough to do a 1/4 mile pass.

Newer brushless motors and speed controllers make it more viable, but like pointed out above you'll need a stout enough charging system that you'll put more drag on the motor. If it takes Xhp to spin a blower, that's what it takes either off the engine or an electric motor has to provide. Now generating electricty is full of losses, so to not drain the battery you'll end up losing the same if not more power to keep up.
