Reasons Why Our Compound Turbos Work So Well

  • A lot more cool air enters the cylinders, because the dual staged compressors work together within their most efficient zones.  The boost air is typically over 100 cooler per pressure made than from a single turbo.
  • The air entering the cylinder is at higher pressure, bringing the boost pressure and exhaust drive pressures near a 1:1 ratio.  The intake stroke can actually produce power.
  • There are additional air molecules in the cylinder which do not get involved in combustion which carry the heat out of the cylinder (similar to how a jet engine is cooler).
  • It has more complete combustion in the cylinders because there’s more air in the cylinder to burn all of the fuel.

Head Studs Recommended For:

  • 1988-2002 engines over 48 psi boost, and fire rings for over 55 psi boost
  • 2003-2007 engines over 55 psi boost, and fire rings for over 65 psi boost
  • 2007.5-2018 6.7 engines, over 48 psi boost, and fire rings for over 55 psi boost 
  • Our Compound Turbo systems are all capable of over more than 55 psi, but are adjustable depending on truck.

  

Our Chummins Compound kits have many unique design characteristics like our S400 Race Compressor housing, with a tight elbos.  Cast and machined hot pipe, special molded tubing, giving our kit alone the ability to fit into the complex Conversion Projects, including Cummins swap suburbans,  12v Cummins swap Chevys, and other 5.9 Cummins engines in a Chevy truck.

Where else can you find a Compund kit for your conversion.  No where, but here.  

Horsepower, and torque are increased throughout the entire RPM band, and significantly increased in mid and upper range.  

 **While a downpipe is not included in this kit, we do include a machined exhaust adapter/reducer which v-band clamps onto the exhaust outlet of the S400 turbo, so that a 4” or 5” exhaust pipe can be welded or v-band clamped onto it.  This makes it very convenient to attach whatever exhaust system you have to your cummins swap.   We do offer a 2nd gen Dodge downpipe which will be close but made need adjustments to fit the Conversion projects. 

** 1-Year, Limited Warranty. 

Free shipping to the lower 48 states.  When shipping to anywhere outside of the lower 48 states, additional shipping fees may apply. 

FAQ's

Q:  What are Chevy Cummins swap problems with Fummins compound turbo kits?

A:  The biggest Chevy Cummins comversion problems, are clearing the heater core with compounds, DPS Chummins kits completely clear the heater core.

Q:  What brand of Chumins swap kit does DPS Chummins compound turbos fit?

A:  As far as we know, our Chummins Compound Turbo Kits fit all Chumins swap kit brands.

Q:  Are DPS Chevy Cummins twin turbo kits compatible with other turbos.

A:  Generally to clear the heater a/c box our turbos must be used.

 

 

Please Note: Chevy/Cummins or any other conversion kit are considered a custom application.  The hardest part of these conversion kits are getting both turbos to fit in the truck and clear the heater core. Our compound kits are specifically designed to get both turbos to fit nicely. In most cases the intercooler hose will fit to a factory intercooler, and will allow the intake to fit as well, however because all of these conversion kits are so custom in nature it is the responsibility of the installer to tie in the intercooler, exhaust and intake tubing into the truck.  This is because the engines, alternators, batteries, intercoolers, etc. can be done in some many different configurations it would be impossible for any single kit to universally fit every swap application.  In most of the conversion applications, expect to do some fabricating to exhaust pipe, intake and/or intercooler tubing.
