Injector Dynamics X-Series Injector Set – S2000

Description

With the Injector Dynamics Series X injectors setting the current standard for high flow injectors, and the recent release of the ID1050x, many are asking what makes these injectors perform at such high levels.

The simple answer is intent. It is no surprise that an R-Compound tire designed for track use will outperform a standard street tire, even if both come from the same manufacturer.

The same can be said for the performance of the ID1050x, ID1300x and ID1700x, which are designed specifically for motorsport use.

Combined Expertise
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.

Solutions
Technology is nothing, until it provides solutions. In the case of the ID1300x and ID1700x, our customers made the needs of the market clear. Our job was to pay attention, and develop solutions that would meet those needs. Those needs, and the solutions are described below.

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.

In the case of the ID1300x, all available parameters were fine tuned to achieve the best results, with the ultimate flow limited to ≈ 1300 cc/min to avoid degrading the characteristics critical to operation in a motorsport environment.

Namely, voltage sensitivity and pressure sensitivity described below, and low flow linearity and minimum fuel mass.

At the time of its release, the ID1300x was the highest flowing all fuel compatible high impedance injector on the market.

Racers being what they are – they quickly ran past the limits of the ID1300x, requiring even higher flow.

The ID1700x came next, incorporating unique solutions to the challenges encountered during development of the ID1300x. Namely, the problem of achieving higher flow without degrading critical operating parameters.

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 ID1700x 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
