Super TurboFuelCell as shown in the picture that can be fitted to a Diesel or Petrol engine. The designer of fuel cells is a designer of Jet engines and he had a contract with the American military to both redesign a jet engine to increase power and fuel efficiency. This type of HHO gas unit was used in part to help achieve those desired results. Apparently fuel cells have been tested on jet engines to enhance power and fuel performance. If it has helped in those extreme conditions it can potentially create the desired result of making your engine more green by saving fuel on both petrol and diesel power units. Installation with a little tweaking can reduce fuel consumption by up to 50%. Depending on diesel spend weekly for trucks there is a potential to save up to £400.00 out of every £1000.00 spent. The installation is very simple as the Super TurboFuelCell comes with a graphic installation manual. Remember one litre of water produces a staggering 8,000 litres of HHO Gas....
