In appalling wet and windy conditions, Walker started in third place on the grid after a fast qualifying session.
‘The rain was really bad, and for the first four or five laps I couldn’t see anything!’ Walker said.
‘There was a lot of water on the course, and I dropped to fourth, but then the leader spun out and hit the gravel, which put me third.
‘I caught up with the guy in front, and managed to get past him, but there wasn’t enough time left to get past the leader, Bruno Senna (nephew of Ayrton Senna), so I just had to protect my second place.
But from being eight seconds behind Bruno I was 1.8 sec at the chequered flag so I was pleased with that.’ He added: ‘After the nightmare of the last round (at Oulton Park where he was taken out of the race by another driver and had to go to hospital for a check-up) the result was no surprise to us.
We know the car is quick, it has been all year.’ But Walker lasted only 14 laps in the second race.
He came fast out of the pits, having qualified in second place, and he and Mike Conway went into the first corner, neck and neck.
But Conway pulled away and Walker said: ‘I spent the next five or six laps trying to pass him, and I was setting the fastest lap every time.
But the driver in third tried to overtake me and we both went out.
I managed to rejoin the race, but part of the rear floor was stuck in my tyre and I had to go into the pits, and my race was effectively over then.’ But Walker was pleased with the weekend’s work.
‘It’s about time we had some success.
I’m reasonably happy with how it’s going, because whenever it’s down to me we qualify quite high up, but when you add the element of the other people it goes wrong!’
