I just wanted to see how many people have their compressor mounted in the engine bay like I do. I have caught a little bit of flack for it on some other forums because the heat will kill the compressor. As some of you may know, I have the TRE kit, a Chinese copy of ARB. I am still waiting on a response from TRE about temperature tolerance.
I found out that the max ambient temperature of the ARB pump is 212 degrees F. It has an automatic shut off at 239 degrees F.
I decided to get some temperatures on my pump for myself yesterday. I drove for an hour in 90 degree heat and took a reading as soon as I got to my destination (130 degrees F) I also did this again after getting home (115 degrees F). So it seems while driving, temperatures remain pretty cool. Keep in mind, I did install a hood scoop. The hottest temperatures I got were at idle, not moving which got to 138-140 degrees F. Still Well away from ARB max ambient temperature. So hopefully it is staying cool enough.
Running a trail will probably cause more heat too. Vehicle is working really hard but not moving fast enough for maximal airflow. More information to come!

I got some data for everyone. During intense off road at 90°F, I got temperatures between 135°F and 178°F. On the highway, it stays cooler in the 80°F range.

I've been running a compressor in the engine bay since about 1999 and I've only had to replace two. CoSport rebuilt my first QA I - electrically it worked fine, but wouldn't build hardly any air pressure. The second QA I died an untimely death through circumstances I can't prove. Neither died because of engine bay heat, though. I now have a new model ARB compressor which works better than either of my old QA I compressors. It's been installed for a couple years now and not a hitch. If the compressor is built to withstand engine bay heat then you shouldn't have any issues. Unless you're airing up a tire, a compressor barely runs and then only for very short bursts. If you were trying to air up while the engine bay was closed up and driving it might be a different story. Edward
