Why We Use PCM Engine Heaters on Every Competitive Performance Race Engine
When youâre dealing with a purpose-built race engine, cold starts are one of the harshest conditions the engine will ever experience. Thatâs why every engine we build and service is plumbed for a PCM (Power Cool Manufacturing) engine heater before it ever sees the racetrack.
Hereâs why:
â
Brings the engine to operating temperature before startup
* Aluminum blocks, cylinder heads, pistons, bearings, and valvetrain components are engineered around operating-temperature clearances.
* Preheating allows these parts to expand much closer to their intended running dimensions before the engine is started.
â
Reduces cold-start wear
* Cold oil is more viscous and takes longer to reach every critical engine component.
* Preheating promotes faster oil circulation to the crankshaft, rod bearings, camshafts, timing components, and valvetrain, reducing metal-to-metal contact during startup.
â
Reduces unnecessary idle time
* Race engines are built to perform under loadânot to sit and idle.
* Long idle periods can contribute to increased engine hours, fuel dilution of the oil, carbon accumulation, and unnecessary wear while producing very little useful work.
* Using an engine heater allows the engine to reach operating temperature with far less idle time before heading to staging or the racetrack.
â
Warm weather doesnât eliminate startup wear
* One of the biggest misconceptions is that an engine heater is only beneficial in cold climates.
* Even if itâs 90°F outside, the engine, coolant, oil, bearings, and internal components are still well below their normal operating temperature of roughly 180â200°F. Ambient temperature does not replace proper engine warm-up.
* The goal isnât simply to make the engine âwarmââitâs to reduce cold-start wear and minimize the amount of time the engine spends idling to reach operating temperature.
â
Improves consistency
* Starting each race day from a repeatable operating temperature provides a more consistent baseline for tuning, diagnostics, and overall engine performance.
â
Protects your investment
* Whether itâs a fresh engine or one with many nights of racing, reducing cold-start wear and limiting unnecessary idle time helps maximize reliability and extend engine life.
At Competitive Performance, we donât just build horsepowerâwe build reliable horsepower. Every detail matters, and proper engine preparation is one of the biggest contributors to long-term performance.
Maximum reliability starts before the engine ever fires. Thatâs why we trust PCM Engine Heaters on our race engines.
