Turbos in gasoline applications operate at extremely high temperatures and RPM. If the exhaust stream, including the catalytic converter, is even partially blocked, the increase in exhaust backpressure can lead to thrust bearing failure.
Diesels are setting all kinds of records from land speed to elapsed time. So if you're not already dabbling in diesel performance, you may be soon. Diesel engines are a different type of animal when compared to gasoline engines. While both use the same four-stroke cycle of combustion, diesels use...
In the aftermarket, there are so many upgrades for turbos, especially on the mid-size diesel trucks. So how do you determine which one is right for your application?
General Motors introduced its powerful Ecotec 2.0L direct
Ninety percent of all turbocharger failures are caused by preventable problems or adverse operating conditions. Because of the close tolerances and clearances of these units, and the high speeds at which they operate, it is imperative that they are installed correctly and maintained properly.
What started out in the 1990s as an affordable way for kids to bang around with cars that were often handed down from their parents or siblings, later grew into a fledgling market all its own.
It would be interesting to hear what Nicolaus Otto, credited as the father of the first functional four-stroke IC engine, would say after seeing some of the advanced powerplants dropped into vehicles today.
Introduced in 1993, GM's 4.6L 32-valve dual overhead cam all-aluminum V8 engine - housed in the Cadillac Allante, Eldorado and Seville STS - was considered a quantum leap forward for U.S. automakers. Initially rated at 295 horsepower, the Northstar V8 has grown over the years to an incredible 469 hp...
A few months back, I highlighted a project car being built by Z Sport. The car is now back together and running. Charles Damewood, the car’s owner and a principle at Z Sport, has been driving the car to break in the engine, and get an idea of what needs...
A turbo's basic purpose is to boost power, so when an otherwise healthy engine suddenly becomes anemic, it often (but not always) means turbo trouble.
