OAKENSHAW'S Enzo Mucci endured a disappointing outing at Knockhill in the British GT Championship.

And the Redditch driver says his Atlanta Motorsport team will be unable to compete in the British GT Cup until a planned-for new engine arrives.

Mucci ended with a Did Not Finish and sixth in class from the Scottish double-header.

The Redditch driver took the first 20 minutes of Round Three only to hand over to Rick Pearson who went off the circuit five minutes from the end.

Mucci was given the second drive in Round Four and guided the Renault Clio V6 home sixth.

He heads to Silverstone for Round Five in a fortnight.
