Home made electric blower 

Electric turbo put on the Dastek dynamometer bench. This is very funny experiment with Ford Mondeo and home made electric forced induction. Results are more than impressive!

Idea of this experiment came from some readings on the web. I used to see many ads advertising “magic” electric turbos, chargers, spiral stuff and etc. It’s always mystery if that stuff works, because no magazine or any serious tuning company talks about this kind of equipment.

Few years earlier I owned a very bad family car 1993 Ford Mondeo with 2-liter 16V engine. So I decided to use this car for a particular test. I took this car to the 4WD Dastek loading dynamometer.

In the garage I found electric centrifugal blower that works on 12 volts supply. The airflow at full speed was quite impressive (good thing to dry your hair after bath). To maintain constant power supply I used external 16V car battery. Electric blower was connected directly to the battery and was working on full speed all the time. For additional safety Autronic air/fuel meter with wide band oxygen sensor was used.

I hooked Mondeo to the dyno and started the test. First of all I made few dyno runs just for warming engine, transmission and other components. After that I made first run with completely stock configuration (stock air filter box with usual paper air filter). Max power reached 132.8 hp (documented engine power is 135 hp), so 2.2 hp was lost somewhere while driving 100k+ kilometers. As you see on the dyno curves on the right (yellow line) some over fuelling occurs between 1800-2300 rpm and engine looses its power. This power drop was making me feel crazy while driving on the road, because on low rpm with wide-open throttle the car wasn’t accelerating like it should be.

After the first test run I made some “tuning” work. I replaced rubber hose with special SamcoSport ducting hose and attached my electric blower. As at the first run the accelerator was hit to the floor after 1300 rpm, but at this time electric blower was activated. The green line on the dyno screen shows very impressive results. As you can see additional air fixed over fuelling and completely eliminated power drop al lower rpm. Additional 5 hp was added through all the rpm range. Max power reached 135.5 hp.

Results show us ±5 hp increase, but this is not that simple. Electric blower was located outside engine bay and was sucking cooler air, also dedicated battery was feeding blower with power not loading car generator.
