While it’s fair to say that Germany has more performance tuning houses than the entire world over, when it comes to the game of hot hatch tuning, the UK pretty much rules.
With 224 kW, the Ford Focus RS probably has all the grunt you’ll ever need for the street legal scene, but British tuner BBR have released not one, but four tuning stages for the Focus RS.
After almost two years of meticulous testing and development work, BBR is more than confident that no other Ford tuner around the world will be able to provide such a complete range of performance conversions, which have been properly road, track, and dyno tested so as to offer the best possible driving experience.
If you’re going to tune your already hot Focus RS, you may as well do it properly and go all the way. BBR’s ‘Phase Four’ state of tune unleashes a potent 301 kW and 552 Nm of torque. Those are big numbers for a small car and, in power figures at least, starting to get close to far bigger players like the Audi RS4, BMW M3, Porsche GT3, all of which the BBR Focus RS beats hands down on torque!
At the heart of this package is the BBR developed high-flow motorsport turbocharger, which replaces the factory spec RS unit. This of course, also requires a high flow fuel pump, as the flow required exceeds that of the standard spec Ford item.
“The BBR Hybrid Turbocharger is a fully overhauled unit, with extensive modifications including; all bearings and seals replaced, a CNC re-profiled compressor cover, a billet motorsport 360 degree thrust bearing and thrust washers, a billet larger diameter inlet compressor wheel, central core rotational housing balanced to motorsport spec, ported and flowed compressor cover, turbine housing and wastegate valve.”
The BBR Focus RS Phase One package includes an ECU remap using BBR’s StarChip software, which is said to deliver a dramatically more linear throttle response and boost map. That improvement also extends to mid-range power and torque but with no visible mechanical changes to the car. Initial testing found that the original Ford air intake hose was distorting under full load, and has therefore been replaced with a silicone induction hose. Phase One power output is 255 kW and 499 Nm of torque at 3 350 r/min.
Phase Two of the BBR program sees a new high-flow intercooler, and all inlet air box hoses are replaced with high flow silicon versions. In addition, there is another software remap to get the maximum power from the standard RS fuel system, but without any increase in inlet temperature or air-fuel-ratio. The standard paper air filter is replaced with a motorsport unit. The BBR Focus RS Phase Two package produces 264 kW and 511 Nm between 3 000 – 4 600 r/min.
Phase Three adds a BBR-spec turbo, sports catalytic converter with high-flow sports exhaust. The exhaust system is made from high quality aircraft grade stainless-steel, finished with quad-tailpipes nestled within the Focus RS’s original rear bumper. BBR high flow fuel injectors replace the original Ford parts, but with a special calibration, which is optimised for the increased power level. This third state of tune extracts 285 kW and 525 Nm between 3 000 – 4 650 r/min.
