LPG modding & Valves Tearing?
Hi there guys, I'm running my HEMI 5.7 on LPG and little worried about the valve tearing risk.
Here in Italy there’s a kind of never-ending debate about using LPG as a propellant in HEMI 5.7 engines.
As you may know, LPG is being described as a non-liquid propellant, that apparently has only a unique drawback: valve lubrication.
That is, some engines may suffer from using LPG as a unique propellant, narrowing down valves and seats lifetime; some cases are reported here in Europe about some engines using LPG, tearing down valves after only 30.000 Km. Other engines are being reported to be fully functional after 400.000Km running uniquely on LPG.
Critical factors about using LPG as a propellant, seem to be:
- Global engine mileage
- Engine RPM, where high RPMs engines seem to suffer more
- Engine power, where weaker engines will suffer more
- Valves and seats alloy; tougher or weaker alloys may be crucial, due to exposure to higher temperatures
Having said so, we where wishing to hear from you about this particular propellant usage.
Great if someone could witness it's experience after a long-mid term usage on LPG...
