GearheadGrrrl Posted February 4, 2007 Share Posted February 4, 2007 Looks like the only thing that could beat the ol' dog was that Freightskaker cabover, and it looked to be running an Allison. Quote Link to comment Share on other sites More sharing options...
fullfuel01 Posted February 4, 2007 Share Posted February 4, 2007 all these truck are from Quebec. The blue R-700 got a 375 V8. the year after that he put twin 6'' stack and turn the screw a bit. maybe twin 12'' stack would not even be enough to breathe that black smoke. He's now racing a blue Superliner with a 450 as a base. It was amazing to see that Mack doing it start. The cabover isn't equiped with an automatic, but the guy got a nice hand as you can see. he's the brother of the international with the Detroit. the burgundy Superliner was r is now twin turbo. they call him Big Mack Attack!

Firemack Posted February 7, 2007 Share Posted February 7, 2007 Wow-That is some Mack Power and durability! That Mack takes a beating and comes back ticking, incredible that much horsepower and torque and that Mack just lifts the wheels right off the ground! R models are incredible tough, no wonder we see so many in New York and Phildelphia getting the S**T beat out them on the road everyday and they keep going day in and day out!Thanks for posting the videos!

Lmackattack Posted February 7, 2007 Author Share Posted February 7, 2007 If you count the gears it looks like its a 5 or 6 speed? He did a2nd gear start. 3rd gear and the wheel comes up a little again!!!!.I wonder how that driveshaft was built to with stand all that torque.
