1958 F.W.D. Posted February 28, 2013 Share Posted February 28, 2013 Next time you see Jim, tell him Ken (from Lubrizol) says hello! And we miss him at TMC! Jim and Tom are both good guys!Ken next time you are in town, for Macungie or whatever, get with me ahead of time and maybe I can arrange lunch or dinner. Due to medical issues Jim does not venture very far from his home, but he loves to entertain guests. 1 Quote TWO STROKES ARE FOR GARDEN TOOLS Link to comment https://www.bigmacktrucks.com/topic/30184-all-eyes-are-on-the-new-maxidyne/page/2/#findComment-168427 Share on other sites More sharing options...
rsb502 Posted February 28, 2013 Share Posted February 28, 2013 Has anyone looked at the new Super Econodyne package? Most people dont even know it exists, Mack sets up a pinnacle axle back with all the smart way aerodynamics and Michelin X-one tires, then puts in an MP8 445 Super Econodyne engine and M drive 12 spd transmission with a .78 OD, some 2.66 rears, yes 2.66 rears. the Super Econodyne package has its own engine programming to get the power band down low, it makes 445hp from 1500-1800rpm and 1750 tq from 1080-1380. It looks like the new setup will be pretty good for OTR fuel mileage getters, Oh and the new econodyne engines now have Econoboost torque curves. The MP8 505 Econodyne with Econoboost makes 1500 ft lbs under 1000rpm and stays over 1500 all the way to 1700rpm peaking at 1750 ft lbs, holding over 1500 ft lbs. for over 700 rpm, thats a pretty good toque curve for a 13 liter with emissions on it. 2 Quote "Any Society that would give up a little LIBERTY to gain a little SECURITY will Deserve Neither and LOSE BOTH" -Benjamin Franklin"If your gonna be STUPID, you gotta be TOUGH" "You cant always get what you want, but if you try sometimes you get what you need" Link to comment https://www.bigmacktrucks.com/topic/30184-all-eyes-are-on-the-new-maxidyne/page/2/#findComment-168592 Share on other sites More sharing options...
slpwlker Posted February 28, 2013 Share Posted February 28, 2013 Now how does the trans hold lugging that low and having that much torque on it. I've read the article and it is impressive to say the least. I know it should hold up just throwing it out there.

Please don't insult the former Mack Truck company as Volvo does by associating Mack Trucks and its legendary proprietary engineering inculding the high-efficiency Econodyne engine range with the Volvo D13 (rebadged as MP8) and and Volvo I-Shift (rebadged as mDrive).Mack Trucks pioneered the dieselization of heavy trucks in America. With the introduction of Mack first diesel in 1938, the fuel-efficient Thermodyne engine in the fifties, the high-torque rise and still more fuel efficient Maxidyne engine in 1967 and the Maxidyne V-8 in 1969, Mack revolutionized the heavy-duty diesel engine concept in the trucking industry.Building on that extensive background, Mack Trucks then introduced the Econodyne series engines, which included both Maxidyne and conventional torque rise versions. The heart of the Mack Econodyne was advanced turbocharging and Mack's new chassis-mounted charge-air cooling system offering increased horsepower, improved fuel economy and engine durability. The Econodyne engines were the most efficient engines Mack Trucks had yet produced. The service-proven Econodyne engines emphasized Mack Trucks' decades of leadership in fuel-efficient diesel engines.

I didnt even make a comparison I simply posted info on a new Mack Product if you hate the new Mack go away cause unfortunately Volvo parts are here to stay, dont give me your crap I am getting tired of you basically bitch slapping people on here for their opinions, guess what they are personal opinions let it go, do not quote me again on anything period or respond to my posts. 1 Quote "Any Society that would give up a little LIBERTY to gain a little SECURITY will Deserve Neither and LOSE BOTH" -Benjamin Franklin"If your gonna be STUPID, you gotta be TOUGH" "You cant always get what you want, but if you try sometimes you get what you need" Link to comment https://www.bigmacktrucks.com/topic/30184-all-eyes-are-on-the-new-maxidyne/page/2/#findComment-169336 Share on other sites More sharing options...
RFCDrum Posted March 3, 2013 Share Posted March 3, 2013 I've seen R Models that had the duel element air cleaner and the hood scoop. I know originally the scoop went to the tip turbine but what was the deal with these that had both?

RobThe 300 series had either the scoop (early models '73-'75) then the 2 stage (later models).You may have seen trucks with both,Rob,but they could possibly already been converted to the 2 stage(leaving the scoop useless). The Canadian trucks used the scoop longer in production,and had a foul weather intake set up like the old oil baths,so it used the upper intake tube to return just under the hood .

Yeah,they were gussied up pretty well,couldn't miss 'em! I remember my Dad (on one of our many trips to Upper Michigan),stopped at LaCombe Mack Sales of Green Bay,Wis.for me (I was Vinny's age at the time) and they had "300 Series" coasters and napkins by the coffee pot,as they must have had a visit by the gold trucks! Dad said,"ask if they'll let you have a couple for your MACK collection?".Mr LaCombe said "take as many as you need".Took a couple of each. Nice people they were.
