E&H WRX BACK ON TRACK
Following a lengthy three-year hiatus from the track, the E&H Motors V11 WRX is back better than ever and with its sights set on the world stage. The last five years have seen the car develop into a very competitive platform at the hands of Carl Ruiterman, but with his focus now on competing off-road, younger brother Hans is about to step into the driver seat, and development is set to be taken to the next level with aero refinement on the cards, which should hint at what event his eyes are firmly fixed on.
One of the biggest projects with the hatch has been the development of the new stroked 2.1-litre engine, which produces 650Nm of torque from 3600rpm and all the way to redline. Carl told us they stopped at 29psi (two bar), which produces 597kW (800hp) on Gull E85, but there is plenty more in it with the new BorgWarner EFR 8374 twin-scroll turbo. The block itself features HKS pistons, and Carrillo rods join custom E&H-spec camshafts, oversized valves, and extensively ported heads, and it has also received extensive oiling modifications, with ported galleries, a ported oil pump, a cross- drilled crankshaft, and a specially designed catchcan that uses vacuum to keep oil from storing in the heads and returns it to the custom gated sump quick smart. A new inlet manifold has also been developed, shifting the trumpet location and also moving the traditional throttle-body position to ensure even distribution across all four runners. Carl told us that, over the coming months, he will start to really lean on the engine to find its breaking point, and see exactly how much power it can really make.
In addition, the radiator has been shifted to the rear with a water-sprayer system, side air ducts, and a Davies Craig EWP 150 controlled by the Emtron KV89 ECU. “This is the single biggest improvement we have made to the handling of this car. Both the balance and the braking have been greatly improved by shifting the radiator,” said Carl.
The addition of flares has meant 18x11s with 295s at all corners to provide plenty of grip, and Carl is eager to see how Hans goes behind the wheel and where the aero development can take the already potent hatch.
