Much like the effect on the intake, this results in a flatter, more sinusoidal tone to the exhaust, which most people would say is less exciting than an NA engine of similar design. The turbo also tends to make the exhaust quieter as a byproduct.
What causes turbo whistle? Turbo whistle is the sound of the compressor inside the turbocharger speeding up (also known as ‘spooling up’, which is why it kicks in at the boost threshold (when the turbo starts to kick in) as you accelerate up the rev range.
Why does my turbo sound louder?
A faulty turbo may result in a loud, siren sound coming from the engine. The louder the sound, the worse the problem could be. Here’s the siren noise that typically results from a failing turbo. If you hear this noise, you should consult your mechanic as soon as possible to get your vehicle checked.
Turbocharged cars also have quieter exhaust pipes. The turbo effectively reduces the amount of gas coming out of the exhaust, so it’s not as loud as a non-turbo car.
Does a turbo make your car sound louder? – Related Questions
At what RPM is turbo activated?
You Spin Me Right Round (Like a Turbo, Baby): The turbine in a typical car turbocharger has to spin incredibly quickly. While your car’s engine revs, at cruise, at around 2,000 rpm, a turbo’s turbine can reach rotational speeds of more than 280,000 rpm.
Why do turbo cars not sound as good?
It’s an exhaust(ing) matter!
Exhaust gases that would otherwise have been sent down the pipes are used to spool turbochargers’ turbines. When you take away a portion of the exhaust gases, there’s naturally less to send into the exhaust system.
Do turbos change exhaust sound?
There is little question that turbocharging an engine carries with it performance and fuel-economy benefits. Most also agree, however, that turbos have a knack for muffling engine noise, lowering the tone of the exhaust note, and layering on whooshing sounds.
How can I make my turbo quieter?
Why are supercharged cars so loud?
Centrifugal superchargers provide the most efficient air compression system, and they’re the ones typically found in most vehicles. The sounds that they make can turn heads on the busy street! When the compressed air leaves the discharge outlet, the supercharger creates a whistling, whining sound.
Why do turbo cars pop?
This is accomplished by adding fuel, retarding the timing, and sometimes electronically interrupting the spark to certain cylinders. These last efforts of adding fuel and dropping spark will place unburned fuel in the exhaust which will ignite in the pipes causing the violent popping sounds.
“Pops and bangs” are created by unburned fuel in the exhaust system. When excess fuel enters the exhaust system it increases in temperature and ignites inside the exhaust instead of the combustion chamber. The noise can be exaggerated by fitting a decat or full decat exhaust system.
Is backfire bad for your car?
An engine backfire occurs whenever the air-fuel mixture in your car combusts somewhere outside the engine’s cylinders. This can cause damage to your car’s exhaust or intake if left unchecked — and it also means that your car’s engine isn’t making as much power as it should, and is wasting lots of fuel.
Why do fast cars crackle?
Poor Fuel-Air Ratio
When combustion doesn’t happen in a timely manner, the exhaust valve opens while the air-fuel mixture is still igniting, causing this explosion to “spill” out of the cylinder, making a loud popping noise. In newer vehicles, computerized sensors help ensure the air-fuel ratio is correct.
Why do Lamborghinis pop?
Supercars backfire as a result of unburnt fuel exiting the engine through the exhaust system, where it then ignites and leaves the exhaust at high speed. This sometimes results in a visible flame leaving the exhaust, and is most often accompanied by a loud bang.
Can any car shoot flames?
What is 2 stepping a car?
Two-step is also known as a stutterbox and is a form of launch control. Essentially two-step works as a secondary rev limiter. Two-step works off of your speed sensor so it knows when you’re moving and when you’re not.
You can increase the exhaust sound by drilling holes in it or by taking off the muffler. You can also remove the catalytic converter or install a cat-back exhaust. Consider putting on a performance muffler, cold air intake, turbocharger, straight pipe exhaust, or aftermarket exhaust if you have the money.
How do I make my exhaust spit fire?
All you have to do is tell the car not to cut fuel at high revs with a closed throttle – fuel will continue to be pumped into the engine, but when it isn’t ignited it’ll make a break for the exhaust. And we all know what happens then. Yep, flames.
