Since a Honda from the factory is not designed to be used with a turbo, there are certain things that need to be done to prepare the car to accept boost. The Honda motors are very stout, and can take a good amount of horsepower absolutely stock. The trick is all in the tune. We a...
allowing for a much more powerful combustion process than is possible on naturally aspirated engine setups. Many of the turbo system's components, such as the intake and exhaust manifold, will replace the engine's
Contrary to popular belief this is certainly not a straightforward bolt on part. As you will discover from this article there's lots of additional things needed to make it work. Adding a turbo or supercharger is a fairly complex modification and one which regularly comes up in our forums so...
How a Turbo SystemWorks Engine power is proportional to the amount of air and fuel that can get into the cylinders. All things being equal, larger engines flow more air and as such will produce more power. If we want our small engine to perform like a big engine,...
Turbocharger Design The turbocharger is bolted to the exhaust manifold of the engine. The exhaust from the cylinders spins the turbine, which works like a gas turbine engine. The turbine is connected by a shaft to the compressor, which is located between the air filter and the intake manifo...
Twin-scroll turbos You could opt for a twin-scroll turbo to save the hassle of using two turbochargers. This system is effectively two turbos crammed into one casing, with the exhaust manifold strategically split between the engine’s cylinders. In a standard single-scroll turbocharger, the ex...
The N55 is equiped with a TMAP sensor (temperature-manifold absolute pressure) on the chargepipe before the intake manifold and by reading its output values compared to what is requested by the car's ECU, we can learn more about potential boost leaks. We can also look at wastegate duty cy...
Several things come to mind: Benefits: Heat is energy. If you need the energy of the heat to power something in a car (for example, a turbocharger), it makes sense that you want to keep as much of that heat as possible. This is one of the reasons why you’ll see heat-wrapping ...
Scott started by fabricating a custom tubular exhaust manifold to channel the high enthalpy gasses from the exhaust ports into the turbine inlet of a GarrettGTX5009Rturbocharger. The gasses leaving the turbine discharge then flow into the...
For example if your turbo boosts 12 psi stock, then you don't really want to put more than that while doing the boost leak test. The motor in the pic was built to handle 30 psi of boost. So before tuning it, I wanted to boost leak test it to make sure there were no leaks. ...
