This simple but effective package allows owners an easy solution to hugely improve the performance of their Mk3 Focus RS, but retain the OEM feel of the car. With a Devil Developments / Motorsport Developments map, our own uprated fuel pump solution and our Devil Developments big turbo kit, this package will transform any Mk3 Focus RS with 490-510bhp and 656NM of torque achievable from any healthy car. Supporting modifications required are an uprated intercooler, exhaust system, a forged engine build, with Stage 3 camshafts optional to see a further increase in power of around 10-20bhp & up to 40NM of torque and our own 4bar map sensor solution which allows for boost cut safety.

No other modifications are required – original fuel injectors, standard clutch and and OEM transmission all remain but we do recommend uprating the clutch and fitting a Quaife front differential if Stage 3 cams are fitted as power can peak at over 530bhp. The result from our package is a genuine 490-510bhp and 656NM of torque from 1.9bar of boost that arrives very early with full boost at just 3,000rpm. It drives just like a standard car but with a lot more usable power and responsive torque to improve general drivability. We can offer this conversion as a drive-in, drive-out package fitted at our work shop (or at Motorsport Developments if preferred) from £7,499 fully fitted, mapped and dyno proven.

Devil Developments is now offering a complete uprated head gasket package, with warranty. This includes a better gasket, stronger head bolts for a superior clamping force along with all associated machining and parts, including an oil change and filter.

We’ve built more of these cars than anyone else in the UK at present, including the UK’s most powerful. The forging process takes 3-4 days start to finish. To make a booking, please give us a call on 01903 731194.
