Why our Cummins Towing Compounds 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 works with its bypass ratio). Much cooler EGTs
  • It has more complete combustion in the cylinders because there’s more air in the cylinder to burn all of the fuel.

EGT TEST RESULTS: The following test results were to test different single turbochargers against our towing twins.  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).
