I've just remembered more : it had a Ford 5-litre engine and was run by SuperSport or SuperPower (I forget which) Engineering or Motorsport (I forget which)
Hang on... I'll dig out a programme ... okay, I'm back with the Spring Trophy 1997 programme. 'Twas SuperPower Engineering who ran it and I was right about the engine.
Hey, just looking at the entrants it is soooooo much more varied. Storm, XJ220, Harriers, Ultima, Venturi, McLaren, De Tomaso, Mirage, Porsche, Marcos, CAE Corse, TVR
. Why can't we have that kind of variety nowadays? It's become too big, I reckon.
By the way, I don't think Thyrring and Vann have been the only ones to have campaigned this monster in Brit GTs.
