Leave it to Ny-Trex, the official nitrous system of Diesel Motorsports, and DEI's CryO2 division to design a diesel nitrous system that not only adds quick horsepower, but also takes advantage of every purge to keep your intercooler cool. The Big-Diesel with CryO2, designed for use with any intercooled turbo diesel engine, provides all the horsepower benefit of nitrous oxide with a purge sprayer that will cool your intercooler as you purge nitrous to prevent unwanted gas pockets.
Injecting super cooled liquid nitrous oxide into a diesel engine lowers charge air temps and acts as an oxidizer to promote a clean burn. Purging is part of the advised practice to maintain a safe and reliable system. The CryO2 sprayer mounted in front of the intercooler sprays liquid nitrous oxide directly onto the intercooler core, effectively jump-starting the intercooler. Other systems simply release valuable nitrous oxide into the air during a purge. The Big-Diesel increases intercooler efficiency by reducing incidence of pre-stage heat-soaking that robs power and creates problems in the long run.
