Squirt EFI Controller, you need to select and install fuel system components appropriate for your engine. Most important is that you have fuel injectors that are the correct size in terms of flow rating. In fact, most injectors are a similar size physically, though there tends to be more variation in throttle body injection injectors than in port injectors. Typical dimensions for a port injector are The manifold injector bungs are 0. The fuel supply rail bungs for the top of the injectors are the same size. Here are two TBI injectors. One the left is a Holley 8. TBI injectors apparently similar to some Chrysler TBI injectors, on the right is a GM TBI injector from a 1. Corvette. Injectors that have too large a flow rating will make it difficult to tune the engine at idle and cruise. Injectors that have too small a flow rating can starve the engine of fuel at full power, and seriously damage your engine. To determine how big your. HP of your engine by the brake specific fuel consumption BSFC and divide by the number of injectors. Injector. Size Horse. Power BSFC Injectors Duty. Cycle. for example, a 1. HP 0. 5. 5 lbhrHP 2 Injectors rated between 4. BSFC is the amount of fuel your engine uses to make 1 horsepower for one hour. It is usually between 0. Normally aspirated engines with efficient combustion processes are at the lower end of the BSFC scale 0. To save a bit of calculation, you can enter your engines estimated brake horsepower at the flywheel and the total number of injectors in the form below and press the Compute Flowrate button. Or you can use the following chart to select. Injectors Rating Required for Specified Horsepowerin lbshr and ccminNumber of Injectors. Horsepower. 12. 45. BSFC and 8. 5 duty cycle. Turbosupercharged engines should add 1. Injectors are usually rated in either lbshouror ccmin. The accepted conversion factor between these depends somewhat. You can use this converter.
