- Designed to fit your Cummins engine in a Ford conversion
- Designed to clear the heater a/c core
- Wastegated, allowing boost adjustment
- Performance 3-Piece Exhaust Manifold included
- Pre-tapped pyro ports
- Super high flow air filter
- Kevlar/Nomex lined silicone low pressure charge pipe provide superior flow and fitment compared to steel
- High pressure metal charge pipe.
- Cast hot pipe, not welded thin steel.
- Flexible Steel braided oil supply lines
- Stainless oil drain lines
- S400 Atmospheric Borg Warner turbocharger
- Diesel Power Source S300 High Pressure Wastegated turbo w/360 Thrust Bearing support bracket for Lower (large) turbocharger.
- Lower EGT's by 250-450 degrees, over a single turbocharger.
- Increase horsepower by 22% to 30% depending on your turbo selection.
- Excellent for towing
- Computer Flow Model Tested for unmatched air and exhaust flow.
- Tight to the block fitment
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.
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).
**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 onto it. We also do offer for $175 our 2nd Gen Dodge downpipe which is a close fit but may need slightly modified.
Our Fummins Compound Turbos, fit Ford Cummins conversions including Ford 6.0 conversion to Cummins, 60 to 12swap kit, Ford Super Duty Cummins Swap or a Ford Cummins Twin Turbos on Ford Gas engine to Cummins projects. Whether using a Ford 6.0 to Cummins conversion kit, a 6.4 to Cummins conversion, or any other Ford Cummins conversion. Our Fummins Twin kit will fit awesome, and run amazing.
Please note: Ford/Cummins, 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.
