Boreham Installs 10,000‑Rpm Ten‑K Engine in Escort RS Continuation

Boreham details a 2.1‑litre, 85kg design that pairs billet hardware with 3D‑printed castings to reach a 10,000rpm target.

Overview

  • Output is quoted at roughly 325–330bhp, with Autocar reporting 325bhp and PistonHeads 330hp.
  • The 16‑valve four features individual throttle bodies, a dry‑sump system and an F1‑inspired cylinder head.
  • Boreham says the installed engine is being mated to a bespoke ultra‑lightweight fully floating rear axle ahead of its first test run.
  • The Ten‑K has undergone about six months of dyno calibration and refinement, with DRVN saying initial targets have been exceeded.
  • The Escort Mk1 continuation offers two powertrains, with an alternative upgraded Cosworth‑derived unit rated at 182bhp and development led by former Ford engineers Simon Goodliff and Laine Martin.
