It’s interesting how “turbo” has had so much semantic drift that people don’t even know it’s a specific component in an engine. They just think it means “fast”. Wouldn’t be surprised to eventually see a “turbo” trim levels for EVs someday.

Or it can be used to amplify as in "Turbo Clippy":
(The turbo button slowed the clock rate down for old games and some ISA cards that didn't like faster clock rates.)
But we all have stories of a friend whose machine was slow because they hit the button not understanding what it does. For them it did become the turbo button.
Kept it on except for one ninja game which was unplayable on turbo, using fixed cycle count as delay mechanism. So all enemies and movements were crazy fast on turbo.

Split the turbocharger into a recovery unit, genset, a supercharger and a battery and no more lag.
There are better things you could do to increase engine performance that are lighter, smaller, and cheaper.
Also of you really really want to defeat turbo lag. The easiest way is to seriously delay ignition timing so the fuel is still burning as it enters the turbine leaving more energy for it to extract and therefore staying spooled up.
edit: Not to say your idea wouldn't work, indeed I'd love to see it. Its just not a practical solution. Not that In ever let practicality stop me.

So, ya know, disregard everything above.
Part of it is that there’s another reason besides a turbo to have a little extra energy left in the exhaust: thermal catalysis of noxious chemicals in the exhaust flow. So there’s a bit of unburned fuel going to the cat for emissions control and people have wondered if we can take some of it back after the converter. For a while every time there was a breakthrough in solid state heat recovery someone mentioned vehicle exhaust.
Like, producing 1 bar of boost for a 2L engine is somewhere between 30-70 hp! Turbos extract that energy from otherwise wasted, extremely hot exhaust gases, which is what makes them efficient. That's also what made them an improvement over supercharging for the majority of applications, because in a supercharger that energy cost comes direct from your usable power.
What "fixed" turbolag in any engine that isn't an 8L diesel is things like variable geometry, lightweight turbines, better bearings, better engine management, and just smaller turbos for the same boost.
It's also massively impacted by driving behavior. My GTI with a teensy tiny turbo still has a half second or so of lag if you try to go from no throttle to full throttle, like if you are really bad at "launching", but if you know what you are doing you will be holding some revs such that the ECU can slap open the throttle plate and dump fuel in just a few cycles and get full 1 bar of boost by the time your clutch is fully engaged. I have done this accidentally more times than I would like to admit, which tends to spin the tires :/
Formula 1 adopted the exact system you are describing, but it's stupid expensive for minimal benefit and I would bet is used more for energy recovery from waste exhaust gasses than actual lag reduction, since F1 cars should be able to almost never be in a regime that would result in lag, and if you have spare joules, you can just throw them directly at the wheels instead of the turbo. It's called the MGU-H system.
I'm not sure most people knew what a turbocharger was to begin with.
There are many ways you can make an engine faster. To me the choice of "turbocharger" implies some parallel to the turbochargers actual function, extracting energy from a waste product to process input material at a higher rate.
So this isn't too terrible. It's a bit more like overclocking than turbocharging.
A typical ICE turbocharger is a recycler - the exhaust gases are used to spin the turbo which in turn forces air/oxygen into the combustion chamber (cylinder) at a faster rate, which can be tuned alongside fuel intake for increased power.
Of course, this tends to be harder on the engine and must be accounted for in engine design. It's not free, and you don't want every engine to be turbo.
And rather than be good for endurance it's really good for bursts of power.
In automobiles, if they are powered by something other than exhaust (e.g. electricity) are called "superchargers."
Ah quick web search, I believe they do run off exhaust using "pre-burners" that burn before the burn.
The Raptor is the first operational Full Flow Staged Combustion rocket engine. https://en.m.wikipedia.org/wiki/Staged_combustion_cycle#Full...
SpaceX's advance was going from oxygen rich (where all of the oxidizer and a fraction of the fuel run through the preburner and turbine, as used in the Soviet/Russian engines) or fuel rich (vice versa, used in the Space Shuttle) to full flow (which has both oxygen- and fuel-rich preburners and all of the propellants flow through one turbine or the other).
There is one type that comes closer to a turbocharger's operation: the "tap-off cycle" runs the turbine on gas drawn from the main combustion chamber rather than using a separate combustor. Tap-off cycle engines aren't common but Blue Origin and Firefly are using them.
imagine if i said something like, "after removing all extraneous weight and safety features, my car has been turbocharged."
kinda nonsensical imo, if someone said this i'd just assume they lacked a thesaurus
we put a turbo in your turbo
Biology is crazy, man.
