and the exhaust valve starts to open. While this is happening, cylinder 2 is ending the exhaust stroke, closing the exhaust valve and opening the intake valve, but there is some overlap. In a traditional single-scroll turbo manifold, the exhaust pressure from cylinder 1 will interfere...
The pressure a turbocharger creates is commonly referred to as boost - to make more boost is to create a greater manifold pressure (the pressure of the intake manifold is roughly equal to the pressure of air in the combustion chamber at the end of the intake stroke). Because compressing air...
We think so. The 2015 S550 Ford Mustang body style utilizes a turbocharged 5.7L Chevy LM7 engine that makes 976 horsepower on 14 PSI of boost. This car has been fully built from the ground up by Shane Whalley, a...
Check out this video from Engineering Explained, which gives you an in-depth look at Turbochargers vs Superchargers, as they choose Supercharging for the ultimate forced-induction method: Do turbochargers increase horsepower? Of course, but how much horsepower you’ll gain will vary on a huge num...
Not a perfect experience then? What's perfection? This is about involvement, and all without smashing speed limits. We drove it for hours and hours and only later realised the radio-cassette was dead. Catching the boost just when you wanted is like catching the seventh wave....
the temperature of the air increases. The temperature may increase enough to ignite the fuel before the spark plug fires. Cars with turbochargers often need to run on higheroctanefuel to avoid knock. If the boost pressure is really high, the compression ratio of the engine may have to be re...
The 6.0 Powerstroke unison ring can wear out and need replacement. In this previous post I explained the6.0 powerstroke VGT problemsand shared how to fix them. If the problem is ignored, the unison ring can wear out as well as the vgt arm. Here is a replacement unison ring: ...
Guys explained me how turbo system works and what had happened to my turbocharger and how to avoid further problems. Very competitively priced and covered by 2 years warranty for service! Highly recommend! Thanks a lot! Date of experience: January 12, 2020 UsefulShare Reply from Best Turbo...
Recovering the mostly wasted thermal energy of the exhaust gas of the IC engine via driving the turbocharger turbine and delivering the demanded compressor power gives the required engine boost pressure. The conventional turbocharger performance measurements on the hot gas test bench are based on the...
