david wild Posted December 19, 2015 Share Posted December 19, 2015 You complain about the Hunts and Swiftys and you want to turn them loose with more power ???? Makes me wonder how we moved Cats around with 237s and 300s ?? and yes for you wet behind the ears and needing 1000 HP we moved 235 cats everyday with 300 Macks. Wasn't the biggest load of logs moved in Maine done with a F model with a 237 ??? 1 Quote Link to comment Share on other sites More sharing options...
Michael Droster Posted December 19, 2015 Author Share Posted December 19, 2015 I'm not into the big power I was just curious why Australia listed the same rig 685hp when only shows 605hp...I started hauling stuff with 130hp gas engine in a 6x6 tractor.. Then went to C60/F600-C70/F700 grade trucks with 190hp gas engines.. wasn't until my old B-Model that got to use a diesel engine Not sayin you older gents did use the same gasser's I did, but when you ran then they were new to 20yrs old for me they were 30-60yrs old when I got them Quote Link to comment Share on other sites More sharing options...

Let's not forget that the same engine in a Volvo puts out 700hp with the same gearbox. So 685hp is still less than the "flagship" Volvo. Mack Australia probably wanted the extra hp for the marketing side (it's around 4th behind other makes) and also for the road train market.

Michael Droster Posted December 20, 2015 Author Share Posted December 20, 2015 Well not sure who is running more power but the other American brands stop at 600hp and that seems to be the limit for them since the late 1970's... So Mack's E9-610, MP10-605, and MP10-685 seem to be the trucking leaders... Quote Link to comment Share on other sites More sharing options...
Outback Posted December 21, 2015 Share Posted December 21, 2015 I think the 685 Mack and 700 Volvo motor are almost identical power. American manufacturers measure horsepower with accessories (eg compressor etc) on the motor where European manufacturers measure without. That's why they have always had ponies.

bbigrig Posted December 21, 2015 Share Posted December 21, 2015 The derate on the engines has everything to do with the emission regulations. Aussie rates will decrease slightly as emissions regs increase. Just like in North America. You need a more complete burn per cylinder for more power. Higher in cylinder Temps produce more NOX emissions. EGR reduces in Cyl Temps which curb NOX emissions. Or like more commonly today DEF/urea treats NOX after cylinder. It's all relative. All while engine manufacturers are trying to keep fuel consumption down. Older EGR engines had to up there RPM operating range to compensate for loss of power in the bottom end caused by EGR induction. Newer engines have reduced use of EGR because emissions are treated after the engine. Which in turn has brought operating ranges back into lower rpm's Quote Link to comment Share on other sites More sharing options...
DSCannon Posted January 12, 2016 Share Posted January 12, 2016 The current US MP10 has enough room for 700 hp/2250 lb-ft torque in the Titan especially with the larger cooling package. Add a CX sleeper (all Mack conventional cabs are essentially the same) and you have the truck everyone wants. How do you get? Beat on your favorite sales guys and if enough interest they will build it. Even the guys sweeping the floors in the Mack factories want it.

Baxter Posted January 12, 2016 Share Posted January 12, 2016 Sweden has 750 hp V-8's and if I have the winning powerball ticket this week so will I. Quote Link to comment Share on other sites More sharing options...
Bullheaded Posted January 18, 2016 Share Posted January 18, 2016 Yep, like David Wild said, I hauled 140,000 gross every day with my 88 R Model with an E-6 350 up and down 8 to 12% grades. It did everything my new DD15 505 Detroit will do. (except engine brake power, LOL)Got better fuel mileage too. And it ran every day. 1 Quote Link to comment Share on other sites More sharing options...
1965 Posted January 30, 2016 Share Posted January 30, 2016 My mp10 likes to be ran to 1400rpm. It only see's 1800 when down shifting.Curious have you had any injector or cup problems with the mp10; or is it just mp8 with the problem Quote Link to comment Share on other sites More sharing options...
220cummins Posted January 30, 2016 Share Posted January 30, 2016 Curious have you had any injector or cup problems with the mp10; or is it just mp8 with the problemIt has been in mp7s as well. Quote Link to comment Share on other sites More sharing options...
Dirtymilkman Posted January 30, 2016 Share Posted January 30, 2016 Never did cups or injectors. 120,000 miles on it and only issue is oil usage. 1 gallon every 2700 miles Quote Link to comment Share on other sites More sharing options...

bbigrig Posted February 8, 2016 Share Posted February 8, 2016 Cup issues exist in the MP10/D16 as well. They are not as common as the smaller version MP/D series issues. Quote Link to comment Share on other sites More sharing options...
