623679 发表于 2019-11-22 14:45:51 Um nope that’s not how that works bub, the higher the rpm’s the lower the fuel economy 😂, I can assure you, you are not getting better fuel economy going 85 from 70, you’re just getting from point A to point B quicker, assuming you don’t pull over to take a break every hour

","text":"you misunderstood. I'm not driving 85mph. the truck was governed at 70mph. I opened the threshold so it can breathe. when I drove 40 miles at 75mph my mpgs did in fact increase. my last truck, a 2020 KW T680 could get 10mpg out the factory. when they governed it to 64mph you could get 8mpg on a good day. KW will tell you the same. I'm a numbers guy and I'll take mpgs over mpg any day. my motor was bogging down at 1500 rpm and it took longer to get up to speed. increasing the band allows me to stay in a gear longer which decreases my time to get up to speed from a dead stop. these motors are built to RUN not putter.","replyToPid":259796}

462372 发表于 2019-11-22 15:17:16 yeh, facts and science be damned. I hope your fuel economy keeps getting better and you drive 100mph and rates keep dropping. when you finally go bankrupt we'll all be better off.

670777 发表于 2019-11-22 15:42:06 I’ve heard all this stuff for years. There are scientific facts such as gravity and drag that you cannot avoid. There are studies done that prove the sweet spot for drag vs resistance vs coefficient effect is about 58 mph. Anything over that is a negative effect. Especially on non aerodynamic trucks. And the higher the speed numbers, the more of a negative effect goes, in a snowball effect. Do I suggest driving 58? Not necessarily. But don’t tell me you’re going to drive 80, then complain that you’re going bankrupt.

","text":"never said I was going to drive 80. I drive the speed limit or less. I drive for mpgs.  at the end of the day 40 miles extra is not substantial enough to lose my mpgs.","replyToPid":259817}

173189 发表于 2019-11-22 15:42:29 Every engine has a sweet spot where it is programmed to operate at optimum power, torque, and fuel economy. Different trucks have different gear ratios to do different jobs. For example OTR trucks typically are designed for 70-75mph for long hauling. Dump trucks are typically designed for a top speed of 60-65 for short distance. Swap the roles and neither one will get good fuel mileage. With a Classic Freightliner I consistently get between 6 and 6.5mpg at 71-72mph. Slow down to 60-65 I’m immediately under 6mpg and watching the boost tells the story 15-1700 rpms = 29-34lbs. 13-1500 rpms = 18-29lbs\nWith my computer setting the most efficient power is generated at 1550rpms 30lbs of boost

173189 发表于 2019-11-22 17:21:37 I don’t bid for that weight. Anyone asking for a rate gets the price I have to have at 23.5t. If I load heavy it has to be worth the money
