We didn’t set out to build a supercharger but realised that research being done on radial compressors could be utilised for a charger. The GA Projects team was working on a hovercraft when one of our technicians joked that the radial fan would make a great supercharger. The fan he was talking about was 600 mm (24”) in diameter, which wouldn’t fit inside too many engine bays; never the less a seed of an idea was sown. The first proof of concept model appeared the following day and a prototype began testing just one week later. It took another four months before we were happy with the final product but it was well worth the time and effort.


Estimated construction costs = $70 to $130


All prices quoted are in US dollars. $70 covers the approximate cost of constructing our 24 volt base model including wiring and switches (36 volt models cost about $130 to build). Ducting and air filter are not included as theses prices will vary from vehicle to vehicle.

How it works - Engines waste considerable amounts of fuel (e.g. when idling, coasting or braking). By using your engines charging system to break down water into highly combustable hydrogen and oxygen much of this wasted energy can be recovered. OHH gas can then be reintroduced to the inlet duct via a PCV type valve. Similar to regenerative braking only more efficient. It works on diesel engines too !!!
