Test Vehicle Particulars
Procharged '73 Dodge Charger with blow-through carburetion and water injection

  • 440 Chrysler wedge engine.
  • Pocket-ported stock cast-iron heads, 88cc open chambers, 8.83 to 1 C.R.
  • TRW flat-top pistons.
  • Cometic MLS head gaskets, ARP head studs.
  • Mopar Performance Purple Shaft cam, 280-degrees advertised duration, .520-inch lift,and 112-degree lobe separation.
  • Mopar Performance M1 single-plane intake manifold.
  • The Supercharger Store F-1 ProCharger Supercharger System.
  • Performance Carburetor-prepped Holley 4150 HP Stage II blow-through carburetor.
  • One carburetor setup for E-85, and a separate 4150HP Stage II carburetor setup for gasoline.
  • Extreme Velocity carburetor hat by Superior Airflow Technologies.
  • Magna Fuel, fuel systems, Pro Star 300 pump for E-85 and Pro Tuner 625 pump for gasoline.
  • The Supercharger Store Stage I Water Injection System for both E-85 and gasoline.
  • 1 7/8-inch headers with 2 1/2-inch-diameter head pipes into Turbo mufflers, into 2 1/4-inch-diameter tailpipes. The exhaust system was intact during all runs and dyno pulls. System is very restrictive at these power levels.
  • MSD 6 with a stand-alone, boost timing-retard, which we set to "O" for all pulls. Total timing was 32-degrees. This is a lot of timing for 91-octane pump gas running 16 pounds of boost with 8.83:1 compression ratio and iron heads. However, it's ok with our water-injection system, and it's definitely ok with 105-octane E-85 with our water-injection system.
