I'm not crazy, the attack has begun.
The engine runs all the time, the Rex only for short bursts. Think average heat displaced versus peak displaced.I think there is some man maths or something going on here. Lets take the NV200 dci - 108hp so 80kW ish. That's only got to deal with around 25kW into the cooling system at peak so the idea of a 34hp genny throwing more out seems a bit off. Infact I make it more like 8kW.
