FORD folk hero Dick Johnson's V8 Supercars team faces an uncertain future after plunging into another financial crisis just a month before the start of the season.

Without major sponsorship and having lost a key investor, Dick Johnson Racing - the longest established and one of the most popular teams in V8 racing - is on the brink amid claims that it doesn't have enough funding to make the first event in Adelaide, from February 28 to March 3.

Despite winning the V8 championship in 2010, DJR has barely survived in recent years; it has been rescued from the verge of collapse three times since 2008.

Johnson, 67, remains one of V8 racing's most popular figures 13 years after his retirement.
