The partnership of Injector Dynamics and Bosch Motorsport was formed to combine the unique abilities of two industry leaders, and offer the resulting technology to a new breed of racers.

From import vs domestic drags, to time attack and airport racing, these high boost alcohol fueled engines exceed the capabilities of re-purposed production car parts, creating the need for a purpose built high flow motorsport injector.

High Impedance
The complexity of modern engines often exceeds the capability of aftermarket ECU’s, necessitating the use of OE based hardware and strategies. Peak and Hold injectors, being decades old technology, are not supported by modern hardware, and so the X Series injectors are based on the high impedance Bosch EV-14 architecture.

High Flow
While achieving high flow may seem easy, it poses significant challenges if the resulting dynamic response is to be useful.

Much like the heads on your engine, the valve in the injector can only be opened so far before other problems arise. The challenge then becomes balancing flow against acceptable operating characteristics.

A study was conducted to quantify numerous modifications to the flow path, and resulted in a unique valve and seat assembly, parts of which are manufactured in house by Injector Dynamics. The end result is increased flow without the need to “open the valve” excessively.

At the end of the nearly two year development process, eighteen different variations had been built and tested. Combined with numerous “tunable” parameters, more than 100 variations were tested, and the results speak for themselves, with the ID X Series injectors being used on record setting cars in nearly every form of racing.

Broad Operating Range
If there is one requirement that stands out above the rest, it is the capacity for a broad operating range. Unlike OE applications, where an injector is designed for specific operating conditions, a motorsport offering requires that an injector serve everything from a twin turbo V8 on alcohol, to a 14,000 RPM Hayabusa engine on gasoline.

This requirement is met by offering consistent operation across a wide pressure range, allowing the end user to change the effective flow rate.

While most injectors will run static at high pressure on a test bench, few will perform well dynamically at those same pressures, and even fewer at high temperature with less than ideal battery voltage.
