Rev happiness usually refers to how quickly the thing revs

this
very high redline matches the definition "screamin' " a lot better
like a screamin v8 would go past 8 grand because it gets so high pitched at the top end

this
my 2004 sentra base model was more rev happy than my current car, but it only revved to 6500rpm, my current car revs to 7k, but it takes longer to rev up to redline

This, as well as how "nice" it is as high revs. An old cad like mine with an ancient engine design sounds and feels like disaster at 5500 rpm, a small modern screamer will just be singing.

Dude I loved my 1.8 Sentra but I would not say it's rev happy. Power died off after 5500 rpm pretty much. It was more of a grunty torquey engine than a rev happy one. That thing actually had some real grunt from like 3k to 5.5k.
It did have a fairly light flywheel though

So you can turn any engine into a rev happy one by installing a lightweight flywheel?

This and how smooth the engine feels at high speed and how much power is in the high end IMO.

stay mad pistoncucks

You're a fucking retard. No, you can't because that only affects behavior at basically zero load. You have to put some load on the engine to go anywhere and that's when stuff like cam choice, VVT tuning, VVL tuning, harmonic balance, turbo sizing, intake design, exhaust design, component balancing, valvetrain inertia, and bottom end component inertia like the conrods come into play.

I'm sure you're going to find some stupid nitpicky bullshit in response but a lightweight flywheel does jack fucking shit to improve response in gear.
