A company specialising in performance has revealed… performance. This is Boreham Motorworks’ ‘TEN-K’: a lightweight, four-cylinder petrol engine it intends on bolting inside its continuation Mk1 Ford Escort RS.

So, yes, yes and very much yes. We’ve known for a while now that BM is planning on building a limited number of these Mk1 RSs – as proper continuation cars rather than restomods – and we’ve known they’ll be powered by four-pot screamers.

Indeed, this one gets lightweight internals – the crank, rods, cradle, dry sump, even the cam cover have all been on a diet – along with a 16v cylinder head with “F1-inspired port geometry” said to “optimise gas flow and power delivery”.

And there’s a fair bit of that. BM is targeting some 325bhp – up from the 296bhp we first heard about last year – at a heady, screamy and likely very pleasing 10,000rpm. Been a while since we’ve had a high-revving, naturally aspirated four-pot.

It weighs just 85kg – a really, really big dog! – thanks to 3D printing tech that allows for a ‘sculpted’ engine block that wraps closely around the internals. BM reckons that its developments over the past six months have given this engine “immediate and direct throttle response”.

“The Boreham TEN-K is the result of relentless effort from our engine development team,” said boss of DRVN Automotive – under which BM sits – Iain Muir. “A demonstration of what can be achieved when passion and precision come together.

“With the engine currently installed in the car and mated to the bespoke, all-new, ultra light weight fully floating rear axle I can’t wait to see it fired up for its first test run.”

Neither can we. More as we get it.
