This compound kit is the most unique and innovative Twin Turbo Kit available today, with features like:

• Direct bolt-on application, no cutting or fabrication needed.
• High Flow 3-Piece Exhaust Manifold included in kit.
• The absolute largest air filter on the market.
• Our kits now come with two separate oil drain lines, except for 12V engines that have only one oil drain port.
• Low pressure charge pipe is silicone with Kevlar liner (which is easier to fit than a steel tube). Silicone tubing uses fewer clamps and has better flow characteristics than steel.
• High pressure charge pipe is strong chrome plated aluminum.
• Small turbo has a 150% greater wastegate capacity
• Cast hot pipe won’t crack like welded pipes do.
• Flexible Steel Braided Oil Supply lines.
• Diesel Power Source 64/71/12 Turbo (small turbo)
• S480 Borg Warner (S400 with 80mm compressor wheel) as large turbocharger.
• Support bracket for Lower (large) Turbo.
• Adjustable boost pressure, with spring gate.
• Perfect for the 5.9 cummins turbo upgrade.
  Other upgrade options (Upgrade options include increasing the S480 turbo up to an S483 (83mm compressor, call for pricing).

Diesel Power Source, 5.9 cummins twin turbo kit, performs excellent when Racing, Towing, or Sled Pulling, but is very driveable. SPOOL UP IS SIMILAR TO STOCK, while raising airflow significantly. Customers are amazed at the spool up, and driveability they get from such a high performance kit. **SPOOL UP IS APPX. 1500-1600 RPM RANGE, VERY QUICK FOR THIS SIZE OF KIT.

EGT's are typically reduced by 300-500 degrees, over a single turbocharger.

Boost pressure will typically exceed drive pressure, which can't typically be done with a single turbocharger (with a single turbo, drive pressure is typically about double boost pressure).

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

Specifically tuned for 400 to 850 horsepower applications.

This Twin Turbo diesel Kit was designed on CAD Software, using CFD (Computational Fluid Dynamics) Testing. You will not find a more high tech kit on the market today. Everything fits like it was built from the factory.

Kit includes: Air Filter, Cast Iron Elbow (carries exhaust from the secondary to the primary turbo), Support Bracket for S400 Turbo, 3-Piece Exhaust Manifold (pre-tapped ports for pyro), Complete Air Intake including Air Filter, Silicone Charge Pipe (on Low-pressure end), Chrome Plated Aluminum Charge Pipe, 1-DPS 64/71 Turbo (small turbo, 64/65/12),1-S480 Turbo (large turbo 80mm compressor wheel/ 96m turbine wheel, 1.32 A/R Housing), 2-Steel Braided High Temp Oil Supply Lines, 2-Oil Drain Lines, Turbo & Manifold Gaskets, Oil Line Adapters, Mounting Bolts, Exhaust Adapter (from S480 to exhaust pipe), V-Band Clamps, High Torque T-Bolt Clamps, Low Torque Clamps, Installation Instructions.

Reasons Why Our Compound Turbos Work So Well

The air entering the cylinders is cooler, because dual compressors work together within their most efficient zone. The boost air is typically over 100 cooler 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.

** On 2nd Gen trucks, head studs are highly recommended for boost pressure over 48 psi, and fire rings recommended for boost pressure over 55 psi. This system is capable of well over 60 psi, but is adjustable to below 50 psi, depending on truck.

** On 3rd Gen trucks, head studs are highly recommended for boost pressure over 55 psi, and fire rings recommended for boost pressure over 65 psi. This system is capable of well over 60 psi, but is adjustable to below 50 psi, depending on truck.

** Most S300 and S400 turbos can be used with this kit.
