What psi do turbos run at?
6 to 8 pounds per square inch
The typical boost provided by a turbocharger is 6 to 8 pounds per square inch (psi). Since normal atmospheric pressure is 14.7 psi at sea level, you can see that you are getting about 50 percent more air into the engine. Therefore, you would expect to get 50 percent more power.
How do you know if your turbo is going out?
If you notice that your car isn’t accelerating as powerfully as it used to, or is slow to react to your input, this might be a sign that your turbo is failing. Similarly, a turbocharged car that struggles to maintain high speeds or isn’t able to reach speeds it once could may be experiencing turbo failure.
What happens if your turbo is too small?
If the turbo is too small, you are not running the compressor in it’s “happy zone” of low heat/high efficiency. The same can be said for a turbo thats too large, but because of the low boost pressures there is low heat, so too large rarely has a heat problem.
Why is my turbo losing pressure?
If a turbocharger doesn’t produce enough boost pressure, it won’t work. Low pressure can also be caused by leaking lines or gaskets (allowing pressure to escape before driving air into the cylinders, improper filter maintenance, and a worn or sticky poppet valve can also cause this condition.
What does a faulty turbo sound like?
A loud whining noise – Often, a failing turbocharger will make a loud, distinctive noise when under boost – a bit like a dentist’s drill or police siren if compressor wheel damaged. If you start to hear this noise from your engine, it’s definitely time to have it checked out!
How do I know my turbo size?
A larger A/R will take longer to spool (boost lag) but will be able to flow more air. In short, a small A/R has high response with limited power; a big A/R will result in slow response but with bigger power.
Can a turbo be to small?
Choosing the right Turbo. Each turbocharger is designed to support a specific range of horsepower and engine displacement. If a turbo is too large for your engine, you will have a lot of turbo lag, and if a turbo is too small for your engine you may not reach your horsepower target.

How big should a turbocharger be for a supra engine?
Now that we have talked a little about the pro’s and con’s of each let’s talk about why picking the smallest turbo for our power goals isn’t necessarily the end all advice to turbocharger sizing. Since we need a specific example to talk about let’s go with a mid size turbo and a mid size motor like a 3.0 Liter Toyota Supra motor (2jz).
