Building on the potent GT-500 plant, there are many possible ways of creating more horsepower, from basic bolt ons, to upgraded superchargers, to oversized motors… This is a great article by MM&FF showing three different power stages that are possible for your GT-500:

Stage 1:

JLT cold-air intake
Single-blade throttle body
Supercharger and crank overdrive pulleys
Bassani axle-back race exhaust
Everything else was left completely stock.
Result 580 rear wheel horse power (rwhp).

Stage 2:

(In addition to the existing stage 1 upgrades)
eaton TVS supercharger
Afco heat exchanger.
2.6″ supercharger pulley
720 cc/min injectors
Kenne Belle boost-a-pump
Result 720 rwhp.

Stage 3:

0.020″ overbore
9:1 compression ratio
ford GT Supercar camshafts
3.4L whipple supercharger
Result 800+ rwhp.

The 3.4L Whipple Supercharger crowns the power hungry 5.4L

If this is what I think it is, you can see here a racer 'secret' modification. The four bolts in the center of the supercharger pulley break up the pulley into an inner sleeve and an outer ring, which allows for a quick change of supercharger gearing to change from low boost to high boost pulleys for race days, and then swap back easily back to a low boost pulley at the end of the race day. Very neat.
