Hennessey tunes Ford Focus RS to 405hp with HPE400 kit
US tuner Hennessey has released its HPE400 upgrade for the Ford Focus RS, lifting power to 405hp and promising further performance enhancements to come.
Hennessey Performance has wasted no time getting to grips with the Ford Focus RS, unveiling an HPE400 upgrade that pushes the hot hatch’s output to 405hp. The Texas-based tuner’s first package for the US-market RS lifts power by 55hp over the stock 2.3-litre EcoBoost, and includes hardware and software changes aimed at owners seeking more than the factory 350hp.
The HPE400 kit combines a stainless steel mid-pipe with an electronic exhaust dump valve, a high-flow air filter and revised engine management software. Hennessey quotes peak torque at 425lb ft, a substantial jump from the standard car’s 350lb ft. The company says the kit will be available to order from the following month, priced at $2,995 for parts or $4,995 including installation and dyno tuning at Hennessey’s facility.
Further upgrades planned for the Focus RS
Hennessey has confirmed that this initial package is only the beginning. Work is already underway on further upgrades, with the company developing enhancements to the intercooler, exhaust and turbocharger. No details or timeframe have been given for these additional kits, but Hennessey’s track record with previous Ford models suggests that more substantial power gains are likely.
