What does spooling up mean?
thrust
A: As a jet descends toward the runway, the pilot increases the power to maintain a specific descent rate (usually around 700 feet per minute). Jet engines require time to accelerate, so the increase in thrust (known as spooling up) improves the ability to go around should it be necessary.
What does a spooling turbo sound like?
As the name suggests, a turbo whistle sounds like a high pitched whistle or whining sound, heard when the turbocharger kicks in as you accelerate and the revs go up. For some people, a turbo whistle can be annoying, but to others, it’s actually desirable!
What is turbo spool up?
A turbocharger is an air pump that is driven by exhaust gas. A large turbine will pose little resistance to outgoing exhaust gas, so the engine will be able to make more horsepower, but a large turbine will spin up to speed (“spool up”) much more slowly.

What does spool stand for?
simultaneous peripheral operations online
To spool (which stands for “simultaneous peripheral operations online”) a computer document or task list (or “job”) is to read it in and store it, usually on a hard disk or larger storage medium so that it can be printed or otherwise processed at a more convenient time (for example, when a printer is finished printing …
Why is my car whistling when I accelerate?
If the whistling sound in your car is most noticeable when you accelerate, the likely culprit is a vacuum leak. The system that controls the air flow between the mass air flow sensor and the engine pushes air through a hose. If the hose comes loose or is damaged it results in a whistling sound as air escapes.
At 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.
What causes turbo lag?
Turbo lag is caused by low engine speeds. Basically, when the car is coasting or power is not being applied, there are not enough exhaust gases to spool the turbine/s.
Does downpipe make turbo louder?
Aftermarket Downpipe makes turbo louder louder because it’s wider – allowing sound waves to travel easier without collisions. Downpipe comes in two types: catted downpipe or catless.
What makes a turbo flutter?
Turbo flutter, also known as compressor surge, occurs when you step off the accelerator after achieving peak boost. While the engine shuts off airflow, all the pressure from the turbo is still there — looking for somewhere to escape.
