Towing Milage Boosted Hemi's
 

ok i am about to tow 4000 miles from wa to ga the long way through la, vegas, st louis.
back to the point.
i got a 07 ram QC 4x4 supercharged hemi with ats diesel tranny and other modds not woth note here.
she can run 8.4 psi, normal driving i see 2 psi accelerating.
i was wondering what boosted trucks see on tow milage
non boosted post for comparision.
need and idea for money need to save
Haulin 20ft car haule with house hold goods aswell about 6k in trailer.
thanks

Ehhh, I have a 2008 hemi same as yours but 2wd. I have CAI, exhaust and tuner, nothing big lol. I pulled a 22ft with my old bodydropped '95 Sierra extended cab shortbed on the interstate at 80 and got like 16. I can haul my rockcrawler through mostly hills and curves on a 16ft trailer at like 11-12 average. Both trucks are in the 5,500lb range probably.


I wanted to mod mine more but I'll get into my lifetime powertrain warranty lol.

I know I'd be lucky to see 9 mpg with that much behind me. I averaged 10 mpg on the interstate towing about 6000 lbs of car (car + trailer weight) with an open trailer.

You may do better than that because you don't need the rpm's to make the torque needed to maintain speed.

It's supposed to be sunny and in the 60s all week so we saved the good weather for you :D

What kind of supercharged do you have?

Can't help you much with the towing numbers, I just wanted to say Hemi + Super Charger + ATS tranny, that's Bad A$$!!!

it is a maggie super.
and i like the setup

i will be there later this month early apr

towing update
just bought a car hauler "enclosed"
9-10 mpg tow home
any data log tranny temps
130-140 going to the trailer shop.
150-169 with empty trailer she did get down to 145 once.
engine temp went from 199 to 212
and on another note wa drivers are idoits cutting off truck they just passed hauling a trailer that may or may not be loaded w/o the trailer brake installed yet.

If you think they're idiots there, wait til you visit so cal and into las vegas. It only gets worse lol. Nice set up by the way. My mega could use an extra boost

Maggie is a good way to go but expensive for 08 and earlier lots of custom accesory work.
