Tim Harvey set the pace at Thruxton today (Tuesday 15 April) as teams in the Porsche Carrera Cup GB tested at the high-speed Hampshire circuit ahead of the races there on 17/18 May.Two 40-minute sessions allowed drivers and teams the chance to tune the cars to the unique challenge of Thruxton and it was Harvey (Red Line Racing) who set down the benchmark with two laps in 1m14.5s in the second session. With all the cars running new tyres in the second test session, Harvey used his experience and knowledge of Thruxton to great effect to run a pair of laps that were nearly four-tenths of a second faster than his rivals."Thruxton is a proper circuit and it's great fun to drive," said Harvey, who currently lies second in the championship standings, just one point behind Michael Caine. "It's been a very productive day for us," continued Harvey. "We've been quick all day, which is good. I wish all the races were at Thruxton!"Second fastest and fresh from his double win at Rockingham over the weekend was Tim Bridgman (Team Parker Racing). "That was okay," said Bridgman. "We were concentrating more on race pace and the car is fine."Third and fourth fastest were Phil Quaife and Sam Hancock for Jota Sport as the team posted one of its best days of running so far. Quaife did extremely well to run competitive times despite a badly cracked windscreen, while Hancock was very close to his team mate's best time. "Thruxton has not always been my favourite track," admitted Quaife. "But I'm really pleased with today and I couldn't fault the car." Championship leader Caine (Team Parker Racing) was fifth fastest, just ahead of Nigel Rice (Red Line Racing) who set a scorching pace to head the pro-am1 category times. Rice's best lap was less than a second away from Harvey's best and left him just ahead of Charles Bateman (Team Parker Racing).Just behind Bateman was single-seater racer Duncan Tappy, preparing for his debut race in the PCGB entry. Tappy had been part of the British A1 GP team over the weekend at Shanghai and only landed back in England late on Monday afternoon, so spent the first session just getting a feel for the 911GT3 Cup car. "I instruct at Thruxton, but this is totally different and it is not as easy as it looks. But I'm getting my head round it and I'm definitely improving."Despite having never raced anything other than a single-seater before, Tappy made excellent progress and ended the day within reach of the leading times. He will race the car at Thruxton in mid-May, while the other contenders will now prepare for rounds five and six at Donington on 3/4 May.
