The recommended idle speed for a 5.7 Hemi engine is 600-650 RPM. However, this number can vary slightly depending on the specific make/model of your vehicle as well as any modifications that have been made to it. Additionally, if you are using an aftermarket computer chip or tune for increased performance, then the idle speed may be higher than what is considered ‘normal’.
Generally speaking though, you should expect your 5.7 Hemi to idle at around 600-650 RPM when running properly and without any significant modification or alteration.
The optimal idle speed for a 5.7 Hemi engine is usually around 750-800 rpm. This range is ideal for allowing the engine to maintain its performance and efficiency, while still providing enough energy to keep all of your car’s accessories running smoothly. It’s important to note that this number can vary based on your specific vehicle so it’s best to consult your owner’s manual or a reliable mechanic if you’re uncertain what idle speed should be used in your case.

What Rpm Should a V8 Idle At?
A V8 engine typically has a higher RPM range than other engines, so it’s important to know what the correct idle speed should be. The standard for most V8 engines is between 500 and 800 RPMs when idling. If your vehicle’s idle speed is consistently lower or higher than this range, you may want to have it checked out by a professional mechanic as it could indicate an issue with the engine.
Idle speed can also vary depending on the ambient temperature outside–as temperatures increase, idle speeds tend to drop slightly. It’s important to make sure that your car isn’t too cold or too hot before making any adjustments to the idle speed yourself; even small changes can have big effects on performance and fuel economy over time.
What is a Healthy Idle Rpm?
A healthy idle RPM is the number of revolutions per minute (RPM) a vehicle engine runs at while it is not being accelerated and is in neutral or park. The ideal idle RPM can vary between vehicles, but generally ranges from 600 to 1000 RPMs for most cars. This range keeps the engine running smoothly without overworking or stressing out components like spark plugs and other internal parts.
An engine that idles too low may cause stalling and poor acceleration, while an engine with an excessively high idle speed will waste fuel economy and generate excessive heat that could damage components over time. Additionally, modern computerized systems built into cars help keep the engines operating within their optimal range which helps maintain good performance overall.
How Long Can You Idle a Hemi?
The Hemi engine is a powerful and reliable engine that can last for many years if properly maintained. But how long can you idle a Hemi? The answer to this question depends on the condition of your vehicle, as well as the type of maintenance it receives.
Generally speaking, most modern Hemi engines are designed to be able to idle safely for up to an hour or two while still providing adequate performance. However, more prolonged idling with no driving involved may cause unnecessary wear and tear on parts such as spark plugs and other components which could lead to potential repair costs in the future. It is best practice then, when possible, not to leave your car running for extended periods without driving it; however, there are some exceptions depending on what reason you need the car idled for (such as waiting at a drive-thru window).
In any case though, make sure that you keep an eye out for signs of overheating or smoking from under the hood so that any problems can be addressed quickly before causing further damage or issues down the road.
Should My Rpm Be at 1 When Parked?
No, your RPM should not be at 1 when parked. Your engine needs to idle at a certain speed in order for it to operate properly and stay cool. When the engine is idling too low, there may be a lack of lubrication which can cause damage to the internal components of the engine over time.
Additionally, if you leave your car running with an extremely low RPM while parked, it could potentially lead to carbon buildup and clogging within the combustion chambers due to unburned fuel that remains in these areas. This can create further problems down the road if not addressed promptly and properly. If you want your vehicle to remain healthy long-term, make sure its RPM is set according to specifications provided by your manufacturer or mechanic; doing so will ensure optimal performance from your car as well as prolong its life overall!
5.7 Hemi Idle Adjustment
Adjusting the idle on a 5.7 Hemi engine can be done in two different ways: manually or electronically. Manually adjusting the idle requires disconnecting and reconnecting the throttle cable, while electronically adjusting it requires accessing your vehicle’s onboard computer system to adjust settings like spark timing, fuel injection, and air/fuel ratio. When making these adjustments, always make sure you have read up on any safety precautions that may apply as well as consult an experienced mechanic if necessary for best results.
Normal Idle Rpm Dodge Ram 1500
The normal idle rpm for a Dodge Ram 1500 is around 650-750 rpm. This means that when the engine is running and not under any load, it should be at this speed. It’s important to keep an eye on your truck’s idle speed, as too high of an idle can cause excessive wear and tear on your engine while too low of an idle can lead to stalling or misfiring.

The 2004 Dodge Ram 1500 4.7 liter V8 engine has an idle rpm of 600-650, depending on the condition and age of the vehicle. This is a bit higher than some modern vehicles, but it ensures that you get plenty of power when you need it while also providing optimal fuel efficiency at low speeds.
In conclusion, the ideal idle rpm for a 5.7 Hemi is between 600-750 rpm. It is important to ensure that your engine does not idle too low or too high as this can cause various issues for you and your vehicle. Additionally, if the issue persists after adjusting the idling speed then it may be necessary to have a professional conduct further inspection of your car’s engine in order to diagnose any underlying problems.
