Drivetrain loss will remain the same no matter what horsepower.

Think of it this way, adding forced induction to your car doesnt magically make the drivetrain more efficient. Losses by friction will not dissappear or get better.

If anything the loss will increase due to the movement of additional parts such as a blower or a turbocharger turbine.

Side note, 12% loss can't be right for a stock S2K. I'm thinking 15% is right. C5 vettes have a more efficient drivetrain and they lose 13% from crank to wheels.
Church's dyno reads high.

Yeah but (like in Jurassic park) hold your hand flat and drop 2 droplets of water on your hand at the same spot, they will most likely go in different paths.

Nothing is recreatable hence why it will never be constant.

And yes adding stuff like SCs / turbos will increase loss.

Yo Spec...i dont quite understand the reference to the water droplet taking two different paths...

Well in the movie it was about "randomness" I'm more referring to it as no situation in fluids (or anything for that matter) will ever be EXACTLY the same even if you try to make it the same.

i wonder once you get the diff kit, does it make you loose mroe power to the wheels because everything is larger

Not necessarily, it just depends on the gear design and mechanical advantage within the differential

Sounds to me like the force needed to move driveshaft , wheels, alt, ac compressor will be pretty constant but other factors will vary.

Since increasing the speed of something through water requires more force as speed rises, I would imagine the same holds true for gears submerged in oil.

So the only way to know true hp at the crank after FI is going to be engine dyno or a really lucky educated guess .
