Precision-Flow Fuel Injectors<br />
FAST Precision-Flow Fuel Injectors deliver the outstanding<br />
idle quality, unparalleled flow consistency and<br />
durability essential for high performance EFI engine applications.<br />
Engineered to yield faster throttle response,<br />
reduced clogging and superior fuel atomization, Precision-Flow<br />
Fuel Injectors are manufactured to the tightest<br />
tolerances in the industry.<br />

• State-of-the-art magnetics improve injector opening times in order<br />
to yield faster throttle response<br />
• Precision ground pintle and wide spray angle both help to produce<br />
and deliver superior fuel atomization<br />
• Redesigned valve body resists clogging & improves hot starting<br />
• High-impedance injector models available up to 60 lb/hr for trouble-free<br />
OEM computer or XFI compatibility<br />
• Low-impedance 1 injectors available up to 60 lb/hr for maximum<br />
performance with aftermarket EFI systems, including FAST XFI <br />

Note: Low-impedance injectors can not be used with OEM computers<br />

Choosing your Precision-Flow Fuel Injectors<br />
1. Take your target peak horsepower and multiply by<br />
• .5 for naturally aspirated • .6 for supercharged<br />
• .625 for turbocharged<br />
2. Take that figure and divide by the number of cylinders.<br />
3. Divide by .9 (for 90% duty cycle).<br />
This will give you the lbs/hr you will need from each injector.<br />
Example: 520 horsepower, naturally aspirated V8<br />
(520 x .5=260), (260/8=32.5), (32.5/.9=36)<br />
This application would require 36 pound per hour Precision-Flow Fuel Injectors<br />
(Part #303608). If the formula gives you a number that is not one of<br />
the injector sizes, the general rule is to move up to the next largest size.<br />

The FAST R&D Fuel Flow Bench is a custom built fuel injector dyno that is<br />
unequaled. Designed by FAST engineers, the one-of-a-kind system & allows<br />
for advanced testing & development of an injector’s flow capabilities.<br />
