Mack V8 E9-525 Super Liner Take Off in MINI ME - HHA's Big Day Cab Power House
Here is a clip of a move I did a while ago back from Adelaide to Brisbane - Pulling a Drake 8 line platform with a 300 tonne mobile crane aboard - we had to use the day cab Super Liner to get our length down to avoid using police escorts in South Aust... It was a long trip but the big girl puts out well!! This truck is running about 700-750hp easy.... I still enjoy driving the 12 speed box - Copy Haul Ass....

Like big V8s? Watch this!
View from the cab of my Kenworth going from Melbourne Victoria to Karratha WA with 46 tonnes of re-bar. Gross train weight 77 tonnes on two 45' trailers. My brother's son came with me on this 11,000 km round trip during the school holidays and was the camera man. First clip is the roundabout at Hay NSW. Second clip going through the S - bends at Gladstone SA on the new road train route. Third clip the Heysen Tunnels in the Adelaide hills. We came through the hills in the daytime so we didn't get to see any of the smic - looking interstate trucks which come out at night. Fourth clip the stacked up roadtrain Coolgardie WA. Power of course is Caterpillar's 3408 18 liter V8. Dyno'd at 550 HP at the wheels, equates to about 600 HP at the flywheel. 16 speed Spicer trans.

Why Do Aussie Trucks Have Bullbars?
Why do Aussie trucks have bullbars? This should give you some idea. Best to watch in fullscreen HD. The first clips were with a pretty ordinary dashcam, the last one with all the cattle wandering around was with my GoPro Hero 3+ (great camera) on narrowest field of view, and the one with the friendly cockatoo at home was with my JVC Everio GR D750.
