Answer: The e-Ram is a distant cousin of the full blown turbo or supercharging system which employs a centrifugal impeller that must run all the time. They have to produce matched engine airflow, with high-pressure air compression (4 to 15 PSI is normal). This requires a tremendous amount of HP to drive the device. For example the airflow needed for a 2.5-liter engine at 6000 RPM is 240 CFM. At only 6 PSI, you would need 10 to 15 HP just to create this type of supercharging. See similar questions...

First of all, there are a couple different types of superchargers (positive displacement and centrifugal). The most popular these days seems to be the centrifugal supercharger which is basically the same design compressor as a turbocharger compressor. These compressors both increase in airflow and efficiency with impeller RPM's. (Which basically means that doubling the impeller RPM doesn't double the airflow, it increases the air flow exponentially. See similar questions...

Turbochargers are powered by exhaust pressure while superchargers are driven from the engine crank pulley. Superchargers allow you to attain boost and horsepower on demand. A turbocharger requires the exhaust pressure to build resulting in a "lag" in horsepower increase. A turbocharger will typically have a higher discharge temperature than a centrifugal supercharger. This higher temperature is a result of the turbo impeller spinning faster and the heat generated from the exhaust gas. See similar questions...

All forced induction devices increase air pressure and density in the intake manifold by pumping more air than the engine would use without it. This concentrated charge of air results in a more powerful combustion stroke in the engine's cylinders, resulting in improved performance over naturally aspirated vehicles. A supercharger is connected directly to the crankshaft by a belt; unlike a turbocharger, which is driven by exhaust gases. See similar questions...

First, lets look at how much power the turbo compressor is using. These figures came from a Cummins/Holset presentation at a TDR rally: Generally, 1/3 of the heat energy obtained from burning the fuel in the cylinder is transfered to the crankshaft in a diesel engine. Another 1/3 of heat energy is dumped into the cooling system, and the last 1/3 escapes through the engine exhaust. See similar questions...

Indmar has not tested and cannot approve the use of aftermarket products like these. Improper installation and/or application of these type products can cause severe engine damage, which could void the warranty. See similar questions...

A turbocharger is really a mechanical device that is designed to pressurize air. We most commonly think of a turbocharger being applied to automotive use, so that is how we will describe it, but there are other uses for turbos that vary slightly in design. Think of a turbo as two fans that are connected to each other by a shaft. Exhaust gases coming out of the engine drive one fan, called a turbine wheel. See similar questions...

Any kind of a supercharger device on an engine—including turbochargers and blowers—produces boost. Many things can cause boost to vary, for example: airflow restrictions, turbo condition, amount of load, condition of ambient air and engine efficiency. Boost is not the only thing that determines whether or not your turbocharger is operating optimally: things like temperature and turbine-inlet pressure must also be considered for a complete picture.

Answer: No. Since the e-RAM is over 3.8 inches inside diameter, even with the motor in the center, and its axial blade design, the e-RAM flows the equivalent to a 3.1 inch diameter free-flow intake tube. Also at part-throttle conditions, this not a factor because the flow rates under part throttle condition are much lower as well. We have dyno'ed the e-RAM when mounted but NOT ENERGIZED at full throttle and measured no losses (see dyno results page for this dyno example). See similar questions...

Answer: Yes! The e-RAM works on all internal combustion engines (Gasoline, Natural Gas, Diesel, etc.). Since the e-RAM is just providing additional air-density to the intake, your engine management system will automatically adjust to provide the appropriate amount of fuel and provide the additional HP gain expected from your e-RAM installation. See similar questions...

Answer: Yes! The e-RAM works on all internal combustion engines (car, motorcycle, ATV, Boat, etc.). You just have to make sure that there will be enough room to mount the e-RAM in the compact area available on a motorcycle. The e-RAM will work with your carbureted engine (see next answer for considerations for carburetors). However, 2-stroke engines with simple membrane style carburetors will not respond to the e-RAM pressure. Your carburetor must have a "float-bowl" for correct fuel delivery. See similar questions...

Answer: Yes! The e-RAM works with carbureted engines. You just have to make sure you follow the following guidelines: An e-RAM-FILTER should be placed on the end of the sealed intake tube that feeds the carb with pressurized air. See similar questions...

A supercharger is a blower that basically boosts air into the motor and makes horsepower when accompanied by a custom tune. But unlike a turbo that utilizes exhaust gases to power itself, superchargers use the engine that it's strapped on to force air into the motors for more power. Thus, it takes a certain amount of HP to get a supercharger going. More details on how a supercharger works can be found here: See similar questions...

The Linux/m68k port requires about the same amount of RAM as the other Linux ports: about 4 megs at the minimum. Even if Linux supports less, the recent versions of the Penguin booter do not. 4 MB is no longer enough to load a 2.2 kernel and a ramdisk. Even 5 MB is stretching it. System 7.0.1 uses less memory than the other Mac systems; if you have a low memory machine, you might try running it. If you intend to run Debian 3.0, you are looking at a more usable minimum of 32 MB. See similar questions...
