Why does it sound so different than any other engine on the road? … The 2.5-liter Subaru engine makes use of something called unequal length headers, which are exactly what they sound like. The header piping from cylinders one and three are of a different length than those from two and four.
Why are Subaru engines so noisy?
The release of the high pressure combustion gasses entering the exhaust system causes this noise. Depending on several different inputs into the ECU, such as engine coolant temperature and throttle opening angle, this noise could occur until the engine coolant temperature reaches the desired temperature.
Do Subarus have loud engines?
The engine and road noise are a common characteristic of Subaru vehicles. This has to do with the engine design and the all-wheel drive system and I would guess a general lack on noise cancelling insulation. Not that you need a new car but the last Subaru I drove was much more refined and quieter than older models.
Why do Subarus sound like they are misfiring?
Because the cylinders are situated 180 degrees from each other, they fire with a different cadence or timing than in line fours or V engines. This makes them sound almost like they are stuttering. Many different engine configurations are around and each has a unique sound.
Are all Subarus noisy?
Subaru’s can be noisy (I’ve owned many) and some of that is design elements such as frame-less windows, lighter sheet metal and all-wheel drive. And, if you can afford a nice set of touring tires (Michelin are very nice) buy those- you will be amazed at the reduction in road noise.
Why does the WRX sound so good?
Jason Fenske of Engineering Explained says the reason the WRX STI sounds so unique is due to the unequal length headers in the 2.5-liter Boxer flat-four. It’s a love affair with WRX/STI owners who won’t be letting go of the iconic sound anytime soon. It’s part of the Subie culture.
Why do Subarus knock?
If you hear a knocking or pinging sound coming from your Subaru vehicle’s engine when you accelerate, it could be a sign that something is wrong. There are many things that could make this noise, from unevenly burned fuel (due to an improper air-fuel ratio) to unlubricated pistons.
Why do Subaru turbos sound different?
Why does it sound like the Subaru Turbo cars have a miss at idle that goes away at speed? – Quora. That’s because they do misfire at idle, as do rather a lot of highly tuned performance cars. The are designed for optimum tuning in the power band of the engine.
