Tuthill Porsche enjoyed a useful day’s testing at the start of October with a pair of newly-built Porsche racing cars. Running on the International Circuit at an official Silverstone test day for racing cars only, the 911 pair enjoyed the dry, bright weather and clocked up some very useful test miles.

The beautiful 1965 Porsche 911 2-litre had raced at Silverstone previously, but was fitted with the latest Tuthill engine spec for this test. The new engine produced great power and ran without issue. “Our in-house ‘Evo’ 2-litre race engine with our very own crankshaft, pistons, bespoke exhaust and many other parts is an exciting project which we are currently testing,” said Richard Tuthill. “It has just been on the dyno and producing figures that back up my initial feelings from driving the car. Before it had even been on the track or the dyno, I had (in typical fashion) declared it as the finest Porsche engine I had ever driven! My love for 2.0-litre SWB cars is well known and I am now even more bias towards them.”

Sharing the garage was Tuthill’s latest 3.0 RSR race car, making its circuit debut on the test day. A brand new car built from scratch, the RSR has a full-spec race engine on slide throttles. Starting the day on treaded tyres, the car moved to slicks when the sun came came out after lunch. Pace was good all day and the new-to-Porsche drivers enjoyed their experience. The owners are now looking forward to some fun racing weekends next year!
