Rotary-engined car to race in OSS

A rotary-engined sportscar will compete in the OSS Championship for the first time this season.

Scott Couper will race a Juno prototype featuring a two-litre Mazda rotary engine that is capable of producing 400bhp without turbo assistance.

“I’m grateful to Shaun Childs-irwin who has put the car together and made the package work,” said Couper, who started racing in the Castle Combe GT Series and has also competed in the historic Group C series.

“Amongst other things, it’s been tough to meet the noise regulations, but we’re nearly ready to race now.”

The series has very few regulations, allowing more unusual cars and engines to be used.

OSS championship coordinator Alan Jenkins said: “The OSS regs are such that although the rotary is a two-litre engine there is a formula that stipulates it be moved up a class, reasonably so due to the horsepower it produces.”

Tanner: “Firstly, we get a helmet delivered to us. In the modern age, this is usually a carbon crash helmet, which is probably about 90 per cent of the business these days. Then we set about the process of removing all of the periphery bits and bobs that are on the helmet so we can get to work on the design. “
