FASTEST MINI IN THE WORLD
Dyno testing of the sustainable fuel used in this year’s Fastest Mini in the World race has shown it offers a slight increase in performance compared to petrol.
All of the cars in the annual Brands Hatch contest used Coryton’s Sustain Classic Racing 50 fuel this summer, which reduces carbon emissions by 35%.
But to prove how the alternative fuel is still competitive on track, a Mini A-Series engine was tested by Swiftune on its dyno using the Coryton product and it yielded impressive results.
“The test shows the Sustain Classic
Racing 50 fuel versus the unleaded are virtually the same but the Sustain fuel gives very slightly more power from
7000rpm to 8300pm over the unleaded race fuel – showing a 0.4bhp to 1.8bhp increase,” said Swiftune boss Nick Swift.
“The Lambda indicates the ecofuel does run a very slightly leaner mixture, approx 0.01 Lambda.”
The Fastest Mini in the World race is set to again use the sustainable fuel in 2024 and coordinator Nigel Death believes these test results strengthen the case for making the switch.
“Every driver is always looking for marginal gains and this helps push the agenda of tackling environmental issues and powers you on track,” he said. “It makes me immensely proud of the innovation we’re doing for a club race – the numbers back it up.”
