Whipple supercharger takes a GT500 to within reach of 1000 HP!
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.
