VHP Series 2 to Series Four Conversion

INNIO’s VHP* Series Four* upgrade packages offer the latest technology with field-proven Series Four heads. 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. With these upgrades, you can expect to see increased uptime, reliability, and performance.

What can this upgrade do for you?

More uptime due to longer intervals between overhauls. Up to 60% longer intervals between top-end overhauls; up to 32,000* hours on L7042GSI S4 vs. 20,000 hours on existing L7042GSI engines.
Lowered lifecycle costs through lower oil consumption. S4 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.
