Replacing R/R for better MPG?

Hahaha!
Disconnect electrically only not much improvement.
Total disconnection belt and electrical can be up to a 10% improvement on a small car.

I know turbochargers use exhaust gas to spin them up, but that's not like trying to spin a generator. Even then, I think turbo chargers draw off some HP to spin the turbo. I understand it works to get more air into the engine for even more HP... an electric generator would be a more demanding load and likely would not give a worthwhile return.

Alternator deletes have been done on drag racing machines where batteries last long enough to do a run or 2. So it works for that. But it just wouldn't be practical for much else. Small dedicated gas generator to keep battery charged on a vehicle sans alternator may free up HP for the vehicle, but then it takes fuel to run the generator. Added complication with little to no net benefit... Back to square one again as far as I can tell.

Currently bikes use permanent magnets spun around a stationary stator. The extra power is just dumped into a big aluminum heat sink. I think if an improvement was made it would be to give us field regulation as opposed to resistance. I would like that a lot.

Some bikes capture the energy in a capacitor, that will rout the power to a LED strip around the bike.
The strip will start to glow, as soon as the battery is charged.
Since it's waste energy anyway, it can very well be used for less necessary mods, like decorative lighting

Well if it's wasted any way why not run a little 12v air pump
Fill a one gallon tank with 220 psi run it to an air amplifier this one would give me about a minute of boost at 5psi

Ironton 12 Volt Portable Inflator — 300 PSI Max., 0.3 CFM | Inflators| Northern Tool + Equipment

Volvo does this to some of their luxury cars, called their 'power pulse technology'.
A small compressor, small squirt of air, just enough to take the turbo lag away on their turbo diesels. As if a diesel didn't already have enough low rpm torque...

You could however, insert a blower on the air intake, resulting in about +1HP boost. Not that you'll notice

5psi is worth 2.89hp to me
That's almost a third more power
Why would I want a turbo if I already have to much power from just the amplifier
My bike only needs 15cfm that thing will output 618cfm @38psi from 80psi inlet pressure
It will only do it for like 10 seconds
But my bike would be all splody by then
