What causes turbo lag and slow turbo spool?
Here are some of the most common causes of slow turbo spool and increased turbo lag. A boost leak or an exhaust leak is the most common problem when it comes to turbo lag. Exhaust leaks are affected if the exhaust leak is at the manifold before the turbocharger.
How can I get my turbo spool up faster?
If you are using a standard control system, they can often be re-tuned to get a faster spool up also. If your engine is upgraded with adjustable camshaft timing gears, you can often move them a few degrees in advance and retard. By adjusting these, you can often get a faster spool up.
Why does a jet engine take longer to spool up?
Jet engines take much longer to spool up (i.e. increase RPM) than piston engines, especially at low RPM because of the pressure ratio/increased airflow necessary to keep the compressor from stalling/surging/blowing up every time when changing power settings. The (simplified) jet engine cycle contains a compressor…
What causes a turbo to fail after a hard run?
There’s also the issue of heat soak from exhaust gas. The worst thing you can do to your turbo is switch the engine off immediately after a hard run. “The number one cause of turbo failure is oil “coking”.
