CHRIS Woodhouse took his fourth victory of the season in the Oulton Park Monoposto 1200 - beating last year's champion by 41 seconds.

Woodhouse also set another lap record to go with the ones he has previously set at Silverstone, Pembrey and Castle Combe.

Colin Stone retired with a puncture on lap two, while Geoff Jones finished fifth despite losing his front wing early on.

There was also victory in the 2000 category for Kidderminster team Magic Motorsport with driver Mark Harrison leading from start to finish.

Harrison, whose brother Neil was second, leads the championship with 70 points.
