VHP Series 2 to xCooled Conversion

Experience increased uptime, reliability, and extended lifecycle intervals with INNIO’s VHP* xCooled cylinder head upgrade. Offering enhanced cylinder head cooling by improving the flow of coolant to critical cylinder head components, upgrade options include an upgrade to the scuff-resistant Series Four* piston and a full Series Four power upgrade option with up to an additional 200 bhp. Each of these product features can be combined or used separately to upgrade your existing VHP Series 2 gas engine.

What can this upgrade do for you?

  • Improved reliability when operating on high BTU fuels. With enhanced cooling at the exhaust valve and guide the component temperatures are reduced by up to 40% to reduce stress that can cause unexpected cylinder head failures..
  • More uptime due to longer intervals between overhauls. Up to 60% longer intervals between top-end overhauls; up to 32,000** hours on L7044 GSI engines operating up to 1,680 BHP @ 1,200 RPM continuously. 
  • Lowered lifecycle costs through lower oil consumption. Series Four pistons feature increased scuff resistance and three-ring design, which can reduce oil consumption by up to 67%, reducing makeup oil cost and catalyst masking. 

**Intervals may vary depending on factors such as fuel quality, maintenance practices, and operating conditions. Engine

configuration must be verified for upgrade opportunity.
