Backyard built 8-second Holden

In Drag, Video by fullboost

After running a string of 9.2-second passes, Mark Drew was again piloting his wife’s Holden HR street car at Heathcote. Recent changes include a larger 4in exhaust, Dominator stall converter and a custom inlet manifold which saw the turbocharged LS V8 make a touch over 800hp to the ground at MPW through street radial tyres. The old Holden still retains the factory style column transmission shifter and stock style rear leaf sprung suspension.
