Big Bang Injection | BBi Injectors

BBi injectors are an entirely new breed of Cummins Common Rail injectors, hand built from the ground up with the absolute utmost attention to detail. BBi set out to perfect the common rail injector by identifying plagued issues and improving upon them with extremely strict tolerances utilizing brand new components to surpass your performance needs.

If you are looking for the cheapest performance injectors on the market, these are not them. As stated earlier, no compromises are made in the building process of these injectors. The first testament to this is the fact that BBi will never sell injector nozzles separately from the entire injector. Perfect quality can only be achieved with a highly trained skill set under a laboratory like environment that will not allow outside impurities to affect the quality of the injector, followed by each injector being balanced within a set against one another. Above and beyond the physical aspect of professional assembling, simple nozzle changes cannot lead to the maximum power output generated from altering the injector parameters, such as how BBi builds their injectors.

Now what does all of this mean to you, as the end consumer spending your hard earned cash on a set of BBi injectors? First and foremost, most Cummins owners are familiar with the all too common injector rattle, and have written it off as a byproduct of stock injectors that gets increasingly worse with larger displacement injectors. BBi has discovered and cured the root of the issue with their injectors, thus eliminating injector rattle. Secondly, because each injector is tested at various pressure levels under numerous amounts of load and at different injection events, you can be assured that the injector operates perfectly under any circumstance. Third, BBi ensures that each and every injector has the exactly correct spray angle as well as consistent hole diameter and shape. By doing so, the high pressure fuel is properly able to atomize within the piston bowl for a complete and efficient burn, minimizing any unburnt fuel that would otherwise result in smoke and heat. Finally, because BBi builds complete injectors, as opposed to simple nozzle modification, you are sure to get a properly performing set of matched injectors that has any imperfections and bottlenecks eliminated that will not only reduce power output, but also limit the life span of the injectors.

Here's an example dyno graph demonstrating the power differences that can be made with standard injectors compared to BBi injectors that feature modified injector bodies. Notice not only the increase in top end power, but mostly the sustained power further through the RPM range.
