I've been trying to remember how to plot the points on a turbo map for a while and this kind of helped. Calculating the Volumetric Efficiency on this is tough. Thank you
Oh why not. Video was very very helpful to me. Please explain first part of video with more details if you can. I am ship engineer but it is little bit difficult to imagine what happened inside compressor in any point of diagram when you explaining. Any way thanks alot
Compressor stall (or surge if you prefer) is the collapse of air flow in the compressor. It's very erratic and thus unpredictable. That causes the cyclic loading and eventual failure of the compressor structure. Other failure modes include thermal fatigue of the turbine rotor (leading to cracks and eventual rotor failure), compressor and turbine erosion (from particulates in atmosphere... buy good filtres!) as well as corrosion, both leading mainly to loss of efficiency and eventually capacity. Bearing and shaft failures can occur in poorly lubricated turbocompressors, especially ones cooled by that very same oil. The 1.6HDi engine for example is well known for ravaging turbos in that way (in comparison the 2.0HDi 90/110 is fuckin' indestructible!)
You can see the compressor speed lines on the compressor map. They go from 65000 up to 150000 rpm. You can roughly determine your air flow from the engine rpm. If you also know your pressure ratio, then you can estimate a compressor speed using the compressor map. You can put a speed sensor on the compressor if you really want to know the speed.

When you have 1,88 on your gauge you have 2,88 on the map.The pressure ratio counts atmospheric pressure also and you are removing it.

2JZ research for spool response and heat control brought me here :)

Turbine/compressor wheel damage that results in an unbalanced wheel is not real flash for bearings/shafts.
very nice explained
Nice. So helpful.
How can we figure out for a compound setup?
Thank you
Hi i have a compressor wheel but i cant find its performance graph. Pls help .
Where is video 5. For lb/min
How can one know the rpm of a turbocharger by knowing the rpm of the engine?
You can see the compressor speed lines on the compressor map. They go from 65000 up to 150000 rpm. You can roughly determine your air flow from the engine rpm. If you also know your pressure ratio, then you can estimate a compressor speed using the compressor map. You can put a speed sensor on the compressor if you really want to know the speed.
what is spool?
Can nos be used to get by surge issues...?
No, Nitrous does not increase the volume of the engine. Surge is when the turbo is producing more compressed air than the engine can consume.
Instantly concerned that you are using bing.
Surge and, spike
Downvote for using bing
who uses bing?😆
