HE351CW – Cummins 2003-2007 Turbo Upgrade
This Turbo Upgrade 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 / HE341 and a 3rd Gen Stealth 67 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 67 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 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, this is your best option. When really pushed, this turbo is capable of up to 850 RWHP!
