2003-2007 5.9L Cummins Stealth Mach 1 64mm Drop In Turbo

The Cummins Stealth Mach 1 64 is an upgraded, drop-in, replacement turbo for the 2003-2007, 5.9L Cummins. It is designed to bolt in and require nothing other than removing the factory turbo and dropping this one in its place. The turbo features a custom profile, 64mm (actual measurement 63.5mm) billet wheel perfectly mapped to a modified compressor cover and 65mm, 10-blade turbine inside the HE351's 9cm housing. The Cummins Stealth Mach 1 64 is one of the quickest spooling turbo's we have tested for the 5.9L Cummins. Even the most experienced enthusiast have a hard time telling the difference between a stock HE351 and a Stealth Mach 1 64 during light throttle, daily driving. This is directly tied to the tight exhaust housing and light weight turbine wheel. If you are going to daily drive your Cummins, consider a quick spool-up a "must have". Stock injector / built transmission trucks can expect an easy 100+ RWHP (Rear Wheel Horse Power) gain with no tune adjustment required. With the quick spool and improved top end power, this is a great turbo for towing performance. If you like use your truck for work and have to tow something the Stealth Mach 1 64 is up to the task. We have measured excellent EGT control without sacrificing performance. This charger is the perfect fit for those of you with future plans for a twin kit. Take your time and put the build together in stages. Start by upgrading the factory charger with an easy drop-in and build off it down the road. In a compound or twin kit we have many customers making 950-1,000HP! Of course those builds include a more extensive list of supporting modifications. Still it is nice to know there is a proven formula to follow. On the other hand, if you want street-able power out of a single turbo, we have tested that too. When really pushed, this turbo is capable of over 700RWHP! Calibrated Power tested 100% over Exergy Injectors with a 12mm Exergy Cp3 pump on a 2007 Cummins while sporting the Stealth 64. The truck produced a whopping 722RWHP and made one mean machine on the street! Supersedes models DM1552050202000, DM1682050202000
