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.

Both turbochargers and superchargers are called forced induction systems. They both compress the air flowing into the engine . The advantage of compressing the air is that it lets the engine stuff more air in a cylinder. More air means that more fuel can be stuffed in too. Therefore you get more power from each explosion in each cylinder. A turbo/supercharged engine produces more power overall than the same engine without the charging. 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...

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.

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...

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...

Answer: YES. By using the version of e-RAM with its integral cone filter (e-RAM-FILTER), you mount the e-RAM directly to the intake tube leading to your air flow sensor or MAP sensor. By using the e-RAM with adapters on both sides (e-RAM-INLINE), you can mount the e-RAM in place of a section of your intake tube for cold-air tubes and some MAF equipped cars.

Answer: The only moving parts are the instrument quality rare earth electric motor which is rated for over 800 hours before recommended service (brush replacement) and a metal impeller. It is highly resistant to heat and has sealed no maintenance ball bearings. Because of the low duty cycle (on the race track it is only on for 20 to 40 seconds a lap depending on the road course such as Laguna Seca or Sears Point where testing is done), the e-RAM unit should outlast your engine.

Answer: The 4-6% HP gains are roughly equivalent to 1 or 2 tenths of a second for 0-60, and 2 or 3 tenths of a second in the quarter mile. This may not seem like much but, at the finish line, at speeds of 100 mph (146 feet per second), 1 tenth of a second is 14.6 feet, or roughly a car length. If you beat someone by one car length, that race wasn't even close! See similar questions...
