Why Pyrometers and Boost Gauges Are Essential for Engine Upgrades
When upgrading your engine, one of the most critical aspects is monitoring how your modifications impact its performance. Two key tools for this are the pyrometer and the boost gauge, both of which provide crucial insights into your engine’s health.
Why the Pyrometer Matters
Often overlooked, the pyrometer measures the exhaust gas temperature (EGT), giving you a clear picture of how hard your engine is working. A good EGT reading on flat terrain should be between 700-800°F. However, when hauling a load uphill, EGTs can climb to 900°F. If you hit that mark, it’s time to downshift—continuing at that temperature can stress key components like the cylinder head and turbo, reducing their lifespan.
Monitoring your EGTs helps prevent overheating and extends the life of your engine. If you’ve modified your engine and don’t have a pyrometer yet, it’s a must-have tool. Click the link below to get yours!
The Importance of a Boost Gauge
A boost gauge is equally important, especially for those running turbos. It measures the boost pressure your turbo is adding to the engine. For optimal boost, your system needs to be airtight. Leaks in the charge air cooler or connections (boots) between piping are common culprits for performance issues.
What’s a good boost pressure? It varies by engine and turbo setup, but here are some general ranges:
- CAT C15: 30-35 psi
- CAT C15 ACERT: 35-45 psi
- Detroit 12.7: 30-35 psi
- Cummins N14: 25-30 psi
- Cummins ISX: 30-35 psi
- Cummins X15: 30-35 psi
If your boost pressure falls below these numbers, you might have a leak or a faulty turbo. Maintaining proper boost levels ensures your engine isn’t overworked, leading to better fuel efficiency and less strain on components.
Keep your engine running at its best by ensuring your boost system is airtight. Need a boost gauge? Click the link below to order now!
