Registered. IMO, the Hemi is a louder/mechanical sounding engine than say, a BMW or a Japanese engine. At idle, you can tell that it’s running, and it’s not a “purring” type sound. The mechanics of this engine and its design.
Is the 5.7 Hemi noisy?
For others the 5.7 Hemi has a pretty loud ticking sound either on startup or after its completely warmed up. Not to be confused with a broken exhaust manifold bolt(s), this is a metal on metal tick that comes from the internals of the engine, most likely from the lifters although that’s never been proven 100%.
What is so special about a Hemi engine?
What is so special about a Hemi engine? The Hemi engine’s unique design, which features less surface area, results in less heat loss. This means the engine’s peak pressure can be higher, which can result in better efficiency. Additionally, larger valves mean it’s easier for air to flow through a Hemi engine.
Is a Hemi engine better than a regular engine?
A HEMI® engine is composed of a hemispherical combustion chamber with dome shaped cylinders and matching piston tops. This creates less surface area than traditional engine which means that less heat and energy lost, and more power is produced.
Do all Hemis have a ticking sound?
Chrysler/Dodge maintains that a Hemi tick is normal and has not recalled ticking Hemi engines. That does not mean all is necessarily well. We are not engine designers or engineers. That means we will not say that an engine that develops ticks and is considered “normal” has a design flaw.
Why is my hemi so loud?
Fuel. Low quality fuel can cause the hemi tick.

Is a Hemi engine better than a V8?
First, let’s talk about the many advantages. The Hemi engine, by design, does a better job of burning all the fuel in the cylinder. Also, because of its design versus a flat head, the surface area is smaller and that means less heat escapes, plus peak pressure can be higher.
How long will a Hemi engine last?
5.7 Hemi engines are good for 250-300 000 miles and more if properly cared for and regular maintenance is carried out. Early models suffered from valve seat issues which was rectified after 2008. It’s not uncommon to find high mileage 5.7 Hemi trucks running around today.

Does a hemi make a car faster?
The pistons in the HEMI’s block usually have a higher compression ratio, which quickly delivers more power to the vehicle. There’s no doubt a HEMI can significantly increase performance, but some drivers aren’t fans due to its design.
Why was the hemi banned from Nascar?
According to various sources, the Hemi was banned “not for technological reasons, but because it wasn’t readily available in cars from Dodge or Plymouth assembly lines, ‘readily’ being the key concept.” The thrust of the argument being that it was too costly of an option for the average buyer.
