With more components and a more complex design, turbocharged engines are a little different to their naturally aspirated cousins - which means they benefit from a bit of special treatment when it comes to driving and everyday care. As befits an engineering silver bullet, the turbocharger itself is ingenious. There are many decisions that need to be made when adding a turbocharger to an engine that was not designed for one. It's a well-constructed, good looking and great sounding Japanese rear-wheel drive sports coupe that has stellar handling and more than adequate power delivery in stock form.
On engines where quick spool-up and more low-RPM power are desired, the use of a pair of smaller turbochargers rather than a larger, single unit can help. RPM will save these motors." Right now, at 36 pounds of boost, Morris estimates the engine is making around 5000 horsepower at its 6900 RPM redline—the engine maxes out his biggest dyno, which can only measure to 4515 horsepower.
Just like timing, the fuel system for a turbo Honda is really dependent on the flow characteristics of your motor, the amount of boost you are running, the size and efficiency of your turbo, and so on. We recommend a high pressure fuel pump, properly sized fuel injectors, adequate methods to ensure and control fuel pressure, and always having enough fuel to never have an instance or possibility to run lean (take into account overboost conditions).
When the intake valve opens and pressurized air rushes into the cylinder, the backside of the valve is also pressurized. B16, and all other VTEC motors, will put out more horsepower with less boost than a non-VTEC motor, about 14% on average. Unfortunately, fitting a filter (in an ideal location away from the turbocharger) can be problematic and will require the removal or relocation of some engine bay components in almost every application.
That being said, we must next understand that in the world of turbochargers, the airflow is measured in pounds of mass per minute. This compact engine, along with the very compact, light, and powerful Mazda 13B rotary engine, have both been transplanted into too many different cars to list.
Valve overlap is a situation where both the intake and exhaust valves are open at the same time. There are trade-offs with larger trims, like reduced efficiency on the compressor side and less backpressure on junkyard ls the turbine side. So, while turbocharging is an amazing improvement for petrol engines, its real coup de grace is saving the diesel engine from becoming a smoky relic.
Fortunately, being that most modern turbocharged applications utilize an intercooler (a heat exchanger positioned between the turbo and engine) to cool intake temps, it often becomes the catchall for compressor wheel fragments. This approach generally benefits chassis and engine compartments that are mostly stock and have limited room for a large single turbo, but many builders use twin turbos for aesthetic reasons, too.
An engine is the epitome of the saying that something is only as strong as its weakest link.” Many engines fail because the connecting rods cannot handle the forces that develop in a high-boost, high-horsepower engine. You get more power from upping the boost as that means more air is forced into your engine, and combined with extra fuel to match, means loads more power and torque.
If your blow off valve is weak, or leaks, then you could have problems building boost, or losing boost pressure. For the most part, compressors with large inducers and smaller exducer diameters will flow large volumes of air (mass flow) at lower pressures, while smaller inducers with larger exducer diameters will flow less mass at slightly higher pressures.
With choice mods, the iron block and aluminum head of the over-engineered engine could withstand an output of more than 500 horsepower without changing any major internal components. Boost is the key to your engine's power, but will also be the key to its destruction if you're not careful.
An available GM-exclusive Duramax® 2.8L Turbo-Diesel engine delivers impressive power, including best-in-class† torque, to help give you the push you need to take on steep challenges. Fueling a turbocharged engine always requires more octane than a comparable naturally aspirated engine.
