HeavyGunner Posted June 13, 2019 Share Posted June 13, 2019 2014 Coronado 122sd. I think part of the problem is it’s specd with a 10 speed and fairly tall gears. 1340 or so rpm at 60 in 10th. It doesn’t pull very good at that rpm, constantly down shifting even at the sight of a hill. If it’s not completely flat with no crosswinds or headwinds it’ll hold 60 mph. If there is the slightest hill or wind you’re done. That’s where I think an 18 speed would shine. I think a 250 rpm split would make a world of difference instead of the 500 rpm split of a 10 speed.

Bullheaded Posted June 13, 2019 Author Share Posted June 13, 2019 Ya, that's why mine didn't seem under powered. I have an 18 speed and 4.30 gears. I was at 1650 RPM at 60 MPH.

Maxidyne Posted June 13, 2019 Share Posted June 13, 2019 HG, sounds like they geared your truck for the usual 80,000 pound federal weight limit, no wonder it's a dog at Montana's much higher weight limits.

Bullheaded Posted June 14, 2019 Author Share Posted June 14, 2019 Yes, I'm lucky Mack Tech. I'm not in the big cities. I get to play in the bush and see wildlife. I tried long haul for a couple years on the big roads and I HATED it! LOL. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/57448-new-4900-star/page/2/#findComment-425273 Share on other sites More sharing options...
Bullheaded Posted July 6, 2019 Author Share Posted July 6, 2019 More shameless self promotion, LOL. Don't have a Mack to post any more so this will have to do.

Bullheaded Posted November 30, 2019 Author Share Posted November 30, 2019 Got a free (well I guess not really, LOL) gift from Western Star in the mail today. Got a key chain too but almost threw it out when I didn't notice it taped to the coffee mug bubble wrap. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/57448-new-4900-star/page/2/#findComment-436964 Share on other sites More sharing options...
HeavyGunner Posted December 2, 2019 Share Posted December 2, 2019 Very cool, understanding that the gifts are not actually free I think it’s a really nice gesture from WS to show a little thanks to a customer while marketing their product.

Popular Post Bullheaded Posted December 18, 2019 Author Popular Post Share Posted December 18, 2019 So far so good. Still loving this one. On my third week of snow hauling in the city, and still not one parked regen called for. My 2013 DD15 would have had to do one every night. And this truck will easily outpull it. So don't know if this is a result of going to the smaller displacement, or if it is improvements that have been made to the emission system over the last couple years? But the DD15 was more forgiving if you let the RPM's drop on the hills. This DD13 is stronger as long as you stay on the boost. If you let it fall off the turbo it won't pick up like the DD15 did with it's two stage turbo. I wonder if the new DD15's still have that same bottom end power now that they went to the normal VGT turbo? That 2013 505/1650 DD15 would actually out accelerate our ISX 600 that had with the exact same gearing from a stop light with 140,000 pounds on. But of coarse on a hill at highway speed once you started downshifting, then the ISX would wave ba-by and disappear. 3 Quote Link to comment https://www.bigmacktrucks.com/topic/57448-new-4900-star/page/2/#findComment-438274 Share on other sites More sharing options...
Maxidyne Posted December 18, 2019 Share Posted December 18, 2019 The fortunate lack of regens jives with what I'm hearing- The smaller and harder working engines run hotter inside the combustion chamber and thus need less supplemental regens.
