Although it is not widely known, one of the most successful Porsche powered race cars ever, was not a Porsche. It was a March GTP car, an 83G that, in the hands of Al Holbert, not only won the 1983 IMSA Camel GT Championship, it also won the 1984 Daytona 24-Hour race outright, in the hands of its new owners, the South African-based ‘Kreepy Krauly’ team.
To uncover the history of this great car, we first of all have to take a look at just how the March-Porsche combination came about.
