I have only seen a few of these around but just at Car Shows although that changed on Saturday at the Geelong Revival Motoring Festival.
When I was watching the 1/4 mile runs the fastest was a 10.8 BUT the Trackhawk did a 11.2, the guy driving it said it was his tow car and it prob went faster later on in the day but not bad for a heavy beast.
This was on an unprepped near the Geelong Foreshore.
The people calling the event on the loud speakers lost the plot with talking dribble and not calling out ALL the times when there was a run so I am not sure what car went the fastest on Saturday
