The Holset H1C turbocharger increases the compression rate of air flowing into the cylinder. This increases the amount of fuel injected into the diesel engine, which in turn increases overall engine performance. The Holset H1C turbocharger consists of two parts: the turbine wheel and turbine collector, or housing. The Holset H1C turbocharger was installed in Dodge Ram trucks from 1989 to 1993. In 1994, the H1C was supplanted by the Holset W1HC turbocharger.
The Holton H1C turbocharger has an engine capacity of 10 liters per turbo. The H1C generates between 400 and 500 horsepower, depending on engine configuration. The H1C has an output range of 90 kilowatts to 240 kilowatts. The turbocharger has an airflow output rate of 0.46 kilograms per second, a 54 mm compression inducer and an eight-blade turbine wheel. The spool speed of the H1C is 20 psi by 3,500 rpm.
The Holset H1C is identical in size and dimension to the Holset HX35 turbocharger. The Holset H1C turbocharger is 224 mm long, 250 mm wide and 169 mm tall. The Holset H1C has a minimum mass of 9 kilograms and a maximum mass of 11 kilograms.
Holset recommends the use of Holset-sanctioned service tools when attempting to repair or modify the H1C turbocharger. These tools can be purchased from any authorized Holset dealer. Holset recommends using circlip pliers, wastgate airfeeder adapters and an E-clip tool when repairing or servicing the H1C turbocharger.
