Going thru Rocky Mountains like CA, OR, WA

uh, drop down US95 into Lewiston, there are 3 ramps on that grade along .....

I see more escape ramps in the bitteroot range than anywhere in the country.

 

I live in WA so Im not sure why you asked that?? I travel these roads all the time. Loads coming out dont pay good unless you have a good hookup. They just love abusing out of state flatbedders from the easy with a good paying load in and get him to do a backhaul of lumber for 1.00 to 1.25 a mile, tarped and 48,000 lbs LOL

 

Hey moneymaker do you run the northwest maxxi stuff? Im from norcal and idk how you washington and oregon guys do it. I applaud you guys that do it cause that is so much work

 

I started off my career driving maxi loads (105,500 lbs gross) regionallyand in Canada on a 4 axle truck (1 lift axle) and a 4 axle 53 ft flatbed trailer. After 6 months I started pulling a set of joints with the same gross weight. Once you learn the mountain grades doing that weight and in varying conditions it seems pretty easy with only 80,000 lbs and a single trailer, LOL And yes, it can be a lot more work, thanks for the shout out

 

The tallest mountain in North America is 20320 ft .. it is in Alaska..The tallest mountain in the lower 48 is Mt. Whitney in California... 14505 feet.. Then Mt Elbert 14404 in Colorado.... and there are tons of Runaway truck ramps.. 2 on Wolf Creek alone... and 2 dropping into Lake Havasu city.. Hell I can think of 25 right now.Most of those are in Colorado... The biggest difference is not weather it is the length of the grade, wind and awareness... I am sorry but you are completely wrong on just about everything on this subject.. Not everything is on the Interstate Highway System..

 

Same thing my dad told me! Best advice ever!

 

My point....if reducing airflow helped mpg the clogged filter would to. Since it doesn't , it proves higher elevation would not help mpg. Sent from my iPhone

 

Some peoples logic is downright funny.
You are right, if less air was good we could save money on filters and take out the turbos.
Beware of the mountains. There are volcanoes and dragons circling them.

 

Nobody said anything about less air or reducing air flow. I said that less oxygen in the air at higher elevations causes the ecu to lean out the mixture reducing power but increasing fuel mileage. This debate is like the disparity between an engineer and a technician which usually leads to one side trashing the other.

 

Less air flow = less O2 getting to engine

Thinner air = less O2 getting to the engine

SAME THING!!!!


If an air filter is clogged the engine preforms poorly because it needs more air. It reduces fuel to compensate and reduces power.
In thin air, the engine cant get enough so it does the same thing.


Were debating about something that's theoretical anyway since most motors just suck in more air to compensate providing the air intake is big enough. Trucks get poor mpg through mountain though because they burn 10 times the amount of fuel for a given speed on the uphills and you average that with half the fuel used on downhills. The up hurt it more then the down help.
