HISTORY:

• This A Fuel Dragster was originally the "Budweiser" Top Fuel Dragster from USA, owned and driven by Father & Son Team, Kenny & Brandon Bernstein
• Once the Bernstein's had completed racing the dragster, the car was stored for approx 7 years
• The Dragster was then purchased by Tom Conway, from Conway Automotive based in Oklahoma. Tom Conway has a long successful history with Top Alcohol and A-Fuel Dragsters in the USA
• Tom has also won 2 x World Championship Titles
• Tom chose 2 drivers to drive the A Fuel Dragster:
  a) Mike Lewis - CEO of Schumacher Racing
  b) Hillary Will - Well Respected Female Top Fuel Racer

NOTES OF INTEREST:

• These Nitro Engines are started on Alcohol and once they reach a certain temperature it is switched over to Nitro
• If you try to start it on Nitro watch out "DUCK", especially A Fuel Engines as they are 14 to 1 and a Top Fuel is only 6.5 - 7 to 1
• Once the A Fuel Dragster has completed its pass on the track and the motor is shut down, then the procedure starts: -
• Driveshaft removed before Dragster is towed back (if the driveshaft was not removed and the motor turned over it would blow a cylinder head off)
• Once back in the pits, all 16 Spark Plugs are removed, and all fuel lines removed off the engine, and blown out with air
• Engine is spun over to pump out excess Nitro
• Failure to follow this procedure would have catastrophical results (ie some USA based teams have spun the engines over and blown a cylinder head clean through their transporters)

In the USA A Fuel Cars are known as "BOMBS" because of their Static Compression Ratio
