This compound kit is the most unique and innovative 6.7 Cummins Compound Turbo Kit available today, with features like:
Diesel Power Source, 6.7 Cummins Compound 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 VERY SIMILAR TO STOCK TURBO.
EGT's are typically reduced by 300-500 degrees, over a single turbocharger.
Boost pressure will typically exceed drive pressure. This can't typically be done with a single turbocharger (with single turbos, typically drive pressure is nearly double boost pressure).
Horsepower and torque are increased throughout the entire RPM band, and significantly increased in mid and upper range.
Specifically tuned for 350 to 800 horsepower applications.
This Twin/Compound Turbo Kit was designed on cutting edge CAD/CAM 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 to be there.
Kit includes: Air Filter, Cast Iron Elbow (carries exhaust from secondary to 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 62 Turbo (small turbo, 62/12/65),1-S475 Turbo (large turbo 75mm compressor wheel/ 96m turbine wheel, 1.32 A/R Housing), 2-Steel Braided High Temp Oil Supply Lines, 2-Oil Drain Lines & Fittings, Turbo & Manifold Gaskets, Oil Line Adapters, Mounting Bolts, Exhaust Adapter (from S475 to exhaust pipe), V-Band Clamps, High Torque T-Bolt Clamps, Low Torque Clamps, 4" Exhaust Downpipe, Installation Instructions.
Note: The following test results are on our HT3B Twin Kit (the S475-S483 Twin Kits yield even better results).
EGT TEST RESULTS: The following test results were to test different single turbochargers against our Twin Turbo Kit (this test was on our HT3B twin kit which has less air flow than the S400 series kits). Each test consisted of a sustained 400hp dyno pull. The test truck was brought up to a 400hp on the dyno, and then loaded to hold a sustained loaded pull, equal to pulling a trailer up a grade using 400 hp. The EGT's were read pre-turbo. The results follow:
Test 1 Stock Turbo: Max EGT's reached 1700 degrees, (Test Time: 13 seconds, operator ended test due to excessive EGT's).
Test 2 Competitors Stainless Steel Housing Turbo: Max EGT's reached 1700 deg (Test Time: 17 seconds, operator ended test due to excessive EGT's).
Test 3 Diesel Power Source Twin Turbos: Max EGT's reached 1290 (Test Time: 1 minute, EGT's did not ever exceed 1290 degrees).
FAQ's:
Question 1: If you already have a competitor’s turbo (ie. BD, Phat Shaft, Arora) or an HT3B, can you use it on this kit?
Answer 1: Possibly. give us a call and we can let you know.
Question 2: Why is the kit more than the 3rd Gen kits?
Answer 2: Because 2nd gen kits require the included downpipe.
** For 6.7 L Cummins owners. This kit requires a DPF delete, and removal of the EGR, as well as a programmer with a turbo delete, such as Smarty. For all 6.7 L Cummins this kit is for off-road use only.
** The standard kit is a DPS 62 over an S475. (Add $400 for and S480 (80mm) Upgrade, Add $100 for DPS 64 Upgrade)
** 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.
** On trucks with automatic transmissions, some trucks require relocation of the transmission oil cooler on the side of the engine block, but not all 2nd gen trucks require this.
** Most S300 turbos can be used in this kit.
