2007 Mack Engines
GearheadGrrrl replied to timberhauler's topic in Modern Mack Truck General Discussion
They have said what it weighs yet, but with over 400 horsepower in Maxidyne tune the 13 liter sounds like a winner. Wonder if I could order one in an RB conventional?... Mack's webpage still lists that model. Heck,I'd even tolerate that big Granite cab to get a 400+ horse Maxidayne and put those Cats, Cummins, and Detroits in their place! -
2007 Mack Engines
GearheadGrrrl replied to timberhauler's topic in Modern Mack Truck General Discussion
Given the small volumes in class 8 truck production it makes economic sense for Volvo and Mack to share basic engine castings. However, it makes no sense to have 11, 12, and 16 litre engines each with their own parts when they could have developed a "modular" 2 litre/cylinder engine. That would have given them a 10 liter 5, 12 litre 6, and a glorious 16 liter V8! -
I'm not much up on the finer points of Mack engine uprating, so I'm wondering if this engine can be upgraded to a higher power rating with just a V-Mac I software reprogramming? If more work would be required, what parts would need to be changed? thanks, GearheadGrrrl

Hi, I'm retiring from the Postal Service after many a happy mile driving Macks, with the occasional "kit trucks" like Freightliners thrown in that only made me miss Macks more. Last couple years I've been driving a Capacity spotting tractor after several years behind the wheel of MR cabovers with Allison automatics. I'm looking to buy one of those Post Office Mack cabovers when they get replaced next year, in the meantime I have a soft spot for R models and may give in to temptation. Looking forward to discussing Macks here and "playing with them in my retirement... GearheadGrrrl
