Being young and fearless is a recipe for disaster or massive fun and sometimes both. Thankfully this video is an example of a great day out. The fun is provided by a Subaru WRX engine that’s been boosted to around 370 kW, thanks to a larger turbo, intercooler and performance camshafts, which in turn is bolted to a lightweight tubular steel chassis. “No fooling around” is the instruction from Dad, but it’s all relative.
