‘Aussie Dave’ Grubnic has once again proved he is the speed king tuning Brittany Force to a ground pounding 343.16mph record run just now – that’s 552kph for those playing at home.
After recently breaking the 340mph barrier, Grubnic unleashed the Monster Energy Drink Top Fuel Dragster during Q2 at the Denso Sonoma Nationals today.
After a .819 sixty, Force rocketed pass the 1/8th mile timers at 304.94mph in 2.94 seconds stopping the 1000ft clocks at 3.64 seconds to qualify #1.

When asked where that came from? Grubnic simply quirked, “Uh, the engine.”
