Homemade Inline Electric Supercharger

Electric superchargers, inline or otherwise, own a doubtful term at blessing. Though electric supercharging has been encompassing for decades, it has peerless been quite recently that automotive applications retain met with any degree of benefit. On the other hand, contemporary off-the-shelf parts can fabricate for a different experiment for those with immature displacement engines.

Wiring

Extend from the blower's black wire to your battery's ground terminal. Run an extension from the red wire to a switched power source in the cab or engine bay. Some people run a jumper wire from the power-on side of their fuel pump relay, which is often conveniently located in the black fuse box right next to the ersatz air filter. Doing so will ensure that your electric blower is running whenever the engine is on.

Mounting

You could use 4-inch aluminum tubing with rubber or silicone connectors for your intake tract, or you could go the cheaper route, and use aluminum drier ducting of the same diameter. Begin by removing the rubber air intake tube that connects your throttle body (main engine air valve) to the air filter box. Fabricate an adapter to fit the 4-inch diameter tubing to the throttle body, and measure out between 12 and 18 inches of tubing. Attach the output side of your Turbo 4000 blower to this tube with large hose clamps.

At this point, you could either connect the input side of the blower to the stock airbox (which some cars will require to retain the airflow-sensors), or you could simply mount a cone-style aftermarket air filter to the blower. Cars that use a mass-air flow sensor (you'll see a wiring harness connected to this sensor, which is attached to the air-box) must retain this sensor. You can install the sensor up-stream from the blower input with a 3-inch length of tubing, and secure the air filter to the sensor itself.

Blower CFM

Defective facts head: no electric inline supercharger currently available with off-the-shelf parts is going to refreshment an engine with enhanced than 1.5L of displacement and brew any competency. At 6,400 RPM, all the more a 1-liter engine needs approximately 125 CFM (cubic Feet Per Minute) of airflow. At 2 pounds of boost vigour, that character shoots up to approximately 180 to 200 CFM, which is correctly on the limit of what a comprehensive 4-inch breadth Turbo 4000 marine blower Testament push while delivering 2 psi of impulse.On the acceptable side, 1 psi of boost is normally value approximately 8 percent escalation in potentiality, idea that the aforementioned 60 horsepower, 1.0L engine might stand to cush as all the more as 10 horsepower; not an insignificant development for a 2000 lb motorcar. So, hardihood with the Turbo 4000 marine blower ($35 as of 2010) for any desire of manufacture power.
