Engine risk is a combination of engine stress levels, part durability, and operating levels. The best tuners will learn to manage their risk to get the most power at the right times with out blowing their engine.
The engine’s operating level is closely tied to how much damage occurs when something goes wrong. If you have a small safe engine you probably wont break to many parts if something triggers a spike in engine stress. On the other hand, if you are running a maxed-out turbo charged engine, you can expect some significant damage if something goes wrong. The more horsepower you’re making, the higher the stress levels are.
There are many things that can cause a spike in engine stress and lead to damage. Below is a list of things to keep a close eye on.
- High engine compression relative to boost
- Air fuel ratio leans out significantly
- High nitrous levels relative to engine internal part strength
- General internal part strength
- Over revving the engine
Keeping the components listed above within safe tolerances will reduce the risk of severe engine damage. Pay close attention to part specs when purchasing to make sure it will work well with your engine and other parts. Jumping to excessive levels of boost or nitrous without the proper fuel and internals can result in quick damage.
- Always keep track of your engine flow levels
- Make sure your fuel system can support the air flow of your engine
- See that your engine internals have the strength to handle your engine’s operating level
- Do not use nitrous systems that are more than your engine internals can tolerate
- Monitor your air fuel ratios closely with an AF meter
- Avoid using high compression pistons for forced induction applications
