I have a 2009 ram 5.7 with 35s. I want to add on-board air compressors with a max amp draw of 35amps. Does anyone know if my truck will be able to handle the electrical load? Theres also another compressor with a 26amp draw. Thanks

 

bump. anyone know if the amperage will be ok?

 

DO NOT run that much of a load of the factory canbus.

Run a hot lead directly off your battery with a 30-365 amp fuse and relay. You will be protected twice. The fuse and the battery. The fused hot lead runs into the relay. When you flip the switch the relay flips over and provides power to the compressor.

Easy cheasy ..

Now, when the time comes, show us pics of which compressor you chose and where you mounted it .. i'm interested..

 

yes i was going to run it fused right off the battery using a relay, not sure what you meant by running it off the canbus?

The compressor I plan to mount between the fan shroud and airbox. The tank will fit behind the front bumper underneath the fan shroud. I choose to put them upfront to run a shorter hot wire.

I'll post pics and how well it fills 35s, suppose to fill them in just over 2 mins.

 

I highly doubt you'll be able to constantly run the compressors, but it should be fine for small bursts.
