Holden VL Calais Turbo - Wet lap sandown (very slow)

1987 VL Calais (factory turbo, factory manual) FMIC, normally 12PSI boost (8 for the wet). Very slow lap. Running 205 GT Radial road tyres allround - putting power down and getting grip through corners was nigh on impossible. See 'hairy moments' video also in my channel for a taste for how low the grip was. Excuse the a/v quality. My normal camera mount broke so I had to resort to a piddly little point and shoot on an ebay (rattly..) bracket. Apologies again.
