Motor Racing continues to call for unique products and ideas, one
of the latest being the OZRACE PRODUCTS Fuel Doctor, a fuel regulator and 
distribution system that has the great advantage of controlling pressure 
without restricting the flow.
	OZRACE PRODUCTS Proprietor, Robert Madden ran up against the 
problem with his nitrous equipped drag car of losing fuel pressure during
a run. As there is no fuel reservoir or fuel bowl on the fuel solenoid 
this then meant that the mixture was not consistant for the whole run, 
also meaning that to have correct fuel pressure at the finish line he had 
to run a higher pressure at the start line - thus losing horsepower. Rob 
tried using the readily available range of regulators, but continued to 
suffer from problems. In the end he concluded that since regulators work 
by restricting flow to reduce pressure at idle, when the engine requires 
more flow at higher rpm, such as at the end of a quarter mile, fuel 
pressure is cut dramatically because of the restriction in the system. In 
Rob's case he was losing 4 to 5lb of pressure by the end of a run. 
	The idea for the Fuel Doctor came from fuel injection, where a 
compensator or pressure relief valve bypasses fuel back to the tank to 
govern volume, so that the volume is maintained subject to the bypass 
being correctly tuned beforehand. The Fuel Doctor system is adjustable, 
to as fine as 1/10th. of a pound increments, something virtually impossible
to achieve with standard regulators. Fine adjustment of fuel volume enhances
tuning, especially with nitrous equipped vehicles.
	The Fuel Doctor both single and twin four barrels plus nitrous 
applications, and Rob stresses, the Fuel Doctor is produced from machine 
grade aluminium, that is X-Rayed for maximum quality control. 

	We also manufacture a Booster Spring (Part No. 40050) for the Holley Electric Fuel 
Pump. And with this item installed into the Holley Blue it performs just
short of the latest Holley Black Pump - Check the price, you will see it 
is a more economical than the alternative.
