I seriously doubt a 6.7 Cummins under the hood of Mack CH tractor would make one complete trip across the country at 80,000 pounds GVW all else being equal. The power density of the light duty diesels way too high for the type of longevity class 8 engines are expected to get. Exactly! They are meant to pull much lighter loads. Imagine a 400-500HP gas-burning High Performance Hemi V8 trying to pull 100,000 pounds? At 75mph? Not for long! The class 8 diesels are meant to last. Turning them up to max output can only shorten their life expectancy. Quote "Eagles may soar, but weasels don't get sucked into jet engines."

mrsmackpaul Posted October 19, 2023 Share Posted October 19, 2023 There was only one Superliner sold with a E6 in Australia A few had Cat motors, dunno if any had GM 2 strokes and probably a Cummins or two The rest were E9 The E9 was the most popular big powered truck motor in Australia by a long long way None Mack trucks had big powered motors 8V92 GM's were probably next, a few K19 Cummins, only a few, as in less than a handful of 12V71 and the same for the 3804 Cats Australian requirements are very different, much bigger tonnages at not as higher speed That been said the blokes on the Hume and Newell hwy would of given any U.S. truck driver a run for their money The Hume, and the Newell were high speed interstate runs that probably peaked in the mid to late 80's I reckon the Pacific hwy was a rat race until a couple of big bus (coach) accidents that killed and mamed a lot of people I never traveled the Pacific or Hume much so can't really comment them much Come to think of it I reckon that was what made the government change the laws and stop booking people for rubbish and started cracking right down on the industry Sort of the begining of the end of all the owner drivers Way off topic now The first E9 I ever heard was in western QLD Pulled up on the side of the road and all's quite, next thing I heard, bop bop bop bop that slowly got closer and over the rise appears a Superliner with double deck crates, just bop bop bop past me standing there with my jaw on the dirt Probably only doing 50 - 55 MPH gross out at maybe 130 ton, no weight limits on volume load trailers Made a little 320 feel positively out of date Was between Longreach and Winton and I was heading west, made the hair on back of my neck all stand and gave me goose bump type of deal Dont think I'll forget it Paul Quote Link to comment Share on other sites More sharing options...
JoeH Posted October 19, 2023 Share Posted October 19, 2023 I've only heard one once here in PA, he pulled in next to me at the fuel island. There's no mistaking it's sound for an inline 6. He has it turned up to 600hp IIRC. Quote Link to comment Share on other sites More sharing options...
Freightrain Posted October 19, 2023 Share Posted October 19, 2023 I always loved my 2000 Ford 7.3 Power stroke with a straight pipe. It sounded like a baby E9. I liked running with my rear slider window open as I pulled hills with my race trailer. 1 Quote Larry 1959 B61 Liv'n Large......................

doubleclutchinweasel Posted October 19, 2023 Share Posted October 19, 2023 Yep. The Ford and the Mack had a different sound than, say, a 903 Cummins. Even the Cat 3408 didn't sound quite the same.

mrsmackpaul Posted October 19, 2023 Share Posted October 19, 2023 A bit more useless none accurate information I reckon back in the day when Mack was on top of the world in road train sales, 8 out of 10 road trains were pulled by Mack, later it probably dropped to 6 out of 10 in the 90's when Ccummins and Detroit caught upto the E9 hp, this when the E9 was well over 600 hp in Australia A well tunned E9 will destrot a Mack 12 speed on road train work pretty quick, the road train work is a unbelievable endurance run for any truck, full power shifting huge tonnage for 12 hours straight, it really sorts things out, thats why I never chase more hp, it just won't last under those conditions I would maybe 3 or 4 out of 10 road trains are Mack now, the Kenworth maybe has about the same, maybe slighty more, then the European makes and Volvo would be the most popular Paul Quote Link to comment Share on other sites More sharing options...

mrsmackpaul Posted October 23, 2023 Share Posted October 23, 2023 Australian Macks are a bit different than Yanky ones, a little more hairy chested and less Tesla like lol Australian trucks sit higher and have more exposed none slippery stuff like gay mirrors on the bonnet that all U.S. trucks seem to have Even the Anthem doesn't have all gay pride crap that the U.S. ones appear to have Paul 1 Quote Link to comment Share on other sites More sharing options...
