Electric SuperChargers Mythbusted - Summary

Here is a concise summary of the transcript:

**Title:** Testing eBay Electric Superchargers on a Daihatsu Charade (Mighty Car Mods)

**Objective:** Evaluate the effectiveness of a $300 eBay electric supercharger in increasing power output.

**Key Findings:**

1. **eBay Electric Supercharger:**
* Promised 50 HP gain and up to 5 PSI boost pressure.
* Actual result: **No significant power gain** (only 2 kW increase initially, later revealed to be a loss of power).
2. **Alternative Experiment:**
* Created a "Twin Leaf Blower Charger" using $150 worth of materials (leaf blowers, AG pipe, etc.).
* Result: **Minor power gain** (27.6 kW, up from 24.4 kW stock), but attributed to increased airflow, not compression.

**Conclusion:**

* eBay electric superchargers are essentially **ineffective fans**, not true superchargers.
* They lack the energy and compression capabilities of traditional turbine-driven turbochargers.
* Minor power gains from alternative experiments are not noticeable in the real world and are likely due to increased airflow rather than compression.

Facts

Here are the key facts extracted from the text, numbered and in short sentences:

1. **Vehicle**: The test vehicle is a 1-liter, 3-cylinder Daihatsu Charade from the early 90s.
2. **Initial Power Output**: The stock Daihatsu Charade produces approximately 24.4 kilowatts (first run) and 23.5 kilowatts (second run) on the dyno.
3. **Electric Supercharger Details**:
* Cost: Over $300 for the tested kit.
* Claimed Features: Works on any engine, adds power on top of existing mods, and can reduce turbo lag.
* Claimed Boost Pressure: Up to 5 PSI.
* Claimed Power Increase: Up to 50 HP.
4. **Electric Supercharger Test Results**:
* First run with the supercharger: Gained 2 kW.
* Subsequent runs showed no significant power gain, and at times, a slight decrease.
5. **Alternative "Twin Charger" Setup**:
* Components: AG pipe, Tee piece, silicone joiner, leaf blowers.
* Cost: Approximately $150.
* Test Results: Achieved up to 27.6 kW, the highest figure of the day.
6. **Comparison to Conventional Turbos**:
* Turbos spin over 100,000 times a minute to create usable boost.
* Require significant exhaust energy (heat and pressure).
7. **Conclusion on eBay Superchargers**:
* They are essentially fans, not capable of compressing air to create usable boost.
* Do not work as advertised for supercharging car engines.
