What makes your turbo spool louder?

What makes some turbos louder than others?

On is the blade count some wheels have funky harmonics they create the their blade spacing etc. The other big thing is pressure ratio. Running 50psi on 2-88s on a small block is way louder than 30 psi on 2-88s on a big block making the same power. Compressor cover makes a difference.

What affects turbo spool?

Also, the turbo spool is determined by the size of the engine and the turbocharger. It can also be increased with things as an improved turbo impeller, for example.

Is it normal to hear turbo spooling?

What is a spool up sound on turbo?

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.

How do I make my turbo spooled?

One solution to turbo lag is to keep the engine rpms up. If your car has a manual gearbox, you'd keep to a lower gear or purposely downshift while at speed. If you have an automatic gearbox with manual override, you'd use the function to downshift to kick up the rpms.

What RPM does a turbo spool up?

Most turbos will begin to supply boost at engine speeds of around 2000 RPM. Other turbos, the larger kind installed on bigger engines won't begin to spool up and produce boost until 3000 to 4000 RPM in engine speed.

Do smaller turbos spool faster?

A larger, more efficient turbo can produce more boost, but will spin up more slowly and will not work as well at low rpms. A smaller turbo will have fast spool-up but weak high-rpm horsepower.

Why are turbo cars so quiet?

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 bigger turbos sound louder?

Smaller turbos have a higher pitch whine at much lower RPMs, but higher frequency noises are easily blocked by solid obstructions such as the hood.

Does cold air intake make turbo louder?

Quick answer – Yes. The sound of your car will be louder and more aggressive with a cold air intake. Instead of loudness though, a cold air intake changes the sound of your car engine. You will clearly hear the sound of air flowing into the intake – especially when you rev up the car and then release the throttle.

What makes a turbo flutter?

Turbo flutter, also known as compressor surge, occurs when there is an abundance of pressurized air in the turbo system. When the engine is not able to combust the full amount of air pressurized by the turbocharger, this excess air will build up in the intercooler system.

How do I know if I have a boost leak?

Listen for any hissing noise—this will indicate a boost leak. If the air pressure gauge indicates no buildup of pressure or does not hold for less than a second, that's a sure sign that a major leak exists within the engine.
