4) At 90% efficiency, the alternator is handling 1,067-Watts of shaft energy ( 1.43-hp ).
5) Extracting 8,000-Watts ( 10.72-hp ) at the shaft would require 8,888-Watts (11.9-hp) of input energy from the belt.
6) 9,070-Watts ( 12.25-hp ) from the engine-to-belt.
7) Definitely a cog-belt system as freebeard has mentioned.
8) Clearance to the radiator/ shroud / radiator bulkhead would now be an issue.

Personally, I'd be looking for a way to shave '12 1/4 hp' from mass, rolling- resistance, and aero.
My starting car is a Lotus Europa Special.
Basically a go cart with a fiberglass (flat bottom) body.
Not easy to shave more weight of 640kg - 1410lb.

It's also so low that there's a mad rush to get the windows closed when a Great Dane's thinking about lifting its leg against the car! (1.080m - 42.5 in)

So pretty aero, but some room for improvement.

I don't want to nerf the car's looks or performance when you put your foot down. (worth more original, with removable bits)
A motor generator would help in that dept, as well as fuel efficiency.

So ye; efficient alternator, led bulbs, ram air intake, tuned length exhaust with anti reversion and a Pressure Wave Termination Box, etc is where I'm looking.

Aero:
I'm thinking headlight ..? fairings? what they called?
Side mirror delete with cameras.
Aero hub caps.
Perhaps some kind of rear deck fairing and rear wheel fairings.
The front spoiler alo looks like it could be improved.
