mackcat12 Posted April 18, 2022 Share Posted April 18, 2022 Has anyone heard that Mack is doing away with the Maxidyne engine’s and having only one engine? A friend of mine ordered a new granite dump truck with a MP8 455M engine and it came in with a MP8 415C and the salesman said that you couldn’t get a Maxidyne engine anymore, this engine doesn’t have the low end torque that mine has, mine is the MP8 455M I can run off and leave him on hills,he has complained to Mack and they sent a guy to program the engine to 455hp but it still doesn’t compare to mine and he told him the same thing that Mack was going to offer only one engine and it would be the maxicruise engine. Has anyone else heard anything about this? Mack is famous for the Maxidyne engines for construction trucks I hope this isn’t true.

Onyx610 Posted April 19, 2022 Share Posted April 19, 2022 To answer your question, no I haven’t heard anything in regards to discontinuing it. Although Volvo does like to do sneaky shit and make good things disappear…So wouldn’t surprise me. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/69560-maxidyne-engines/#findComment-495609 Share on other sites More sharing options...

Taking mp ten out Mack and leaving them with no big power to sell was a dummass ignorant move as well! It wouldn't surprise me if they pull Maxidyne as they are pushing the Mtrash trans all this comes down to EPA by the way Maxidyne does not fit the bill when it comes to Emission! the rpm target is small for emission engines hence lots of gears which the mtrash is limited also! We will see! Edited April 19, 2022 by fjh 2 Quote Link to comment https://www.bigmacktrucks.com/topic/69560-maxidyne-engines/#findComment-495634 Share on other sites More sharing options...
james j neiweem Posted April 19, 2022 Share Posted April 19, 2022 Do current Maxidynes still pour in more fuel at low RPM's like the original engine concept.

67RModel Posted April 19, 2022 Share Posted April 19, 2022 (edited) Not that it means anything but the Mack Website still shows 3 "performance specifications" for the MP8: Maxidyne, Maxicruise, and Econodyne. Honestly if you look at the horsepower and torque curves for the Maxidyne and Maxicruse there is almost zero difference. Actually, the Maxicruise makes slightly more peak torque at the lowest HP setting (415). If they are doing away with the Maxidyne I can see why. There is almost nothing different about it to justify its existence and affect on Volvo's bottom line. I'm sure their marketing people did a study and concluded those customers who wanted a Maxidyne would just take the Maxicruise if it was the only option.......

I doubt it. There is so much torque limiting programming going on that you will probably rarely ever get to use the engines "rated output". Emissions. Emissions. Emissions......

The guy that came from Mack said that the Mack marketing team was behind updating all the publications online, he said that they were selling more maxicruise engines than anything else and that’s why they were going to only offer that one, he also said they could program the engine to perform like a Maxidyne so who knows Quote Link to comment https://www.bigmacktrucks.com/topic/69560-maxidyne-engines/#findComment-495679 Share on other sites More sharing options...

Greasygrunt Posted August 5 Share Posted August 5 I drove on weekends and holidays for Alman Construction back in the early eighties. They were hauling rock and dirt where Jones Brothers was doing the road bed for I-440 in Nashville. Alman had Mack’s with the Maxidine in them. They only had 5 gears and part of our route was on I-40. Fortunately the entry ramp was downhill and that helped to get up to merging speed. I don’t know much about trucks any more except how to drive them. The talk on here about the Mack’s is very interesting.
