I'm interested in peoples opinion as to where to permanently mount an air compressor, two schools of thought, under the bonnet or in my case under the drivers
seat. Pros and cons for both, air cooling issue under the
seat and water and dust contamination under the bonnet, this is going in my "Bush Hack" Rangie so it will be spending the majority of it's time in the scrub.Keep the shiny side up

Martyn, you're obviously a better bush
cook than me, because under the drivers
seat is the last place I'd be looking for clean air. I have ARB's mounted under the bonnet of the TD5 and LX470 - no problems with dust or water so far. On the last trip we also had an ARB in a box. It worked
well but the box was an unecessary extra occupying valuable invehicle space.

I also meant to say that the closer the compressor to the baTTERY, THE LESS THE VOLTAGE DROP, and the easier the wiring.

Bob,
I'd also heard about the voltage drop issue all I can say about that is I've had the compressor mounted under the passengers
seat in my GQ and never had a problem with voltage drop, not that I would be able to notice the voltage drop anyway, how would I spot it, would the compressor go slower? I just did a beach run recently and when i got back there was sand under the engine bay, not what I viewed as a good place to store an air compressor. Keep the shiny side up

There shouldnt be a problem with voltage drop no mater where you put it.
To over come voltage drop use larger diameter cables !

Wherethefugawi, I think it does about 20L/100km around town and about 16 on the hwy. On the recent trip (of about 6000km) my mates took it upon themselves to fuel the V8 and I fuelled the TD5. Despite its larger capacity they were always filling at every stop whereas the TD5 was regularly returning over 900 witout the trailer and 700 while towing. Sorry I can't be more specific. Don't get a petrol 100 series or LX470 if you want good fuel economy - its pretty expensive to run.

Martyn,
I wouldn't mount a compressor under the bonnet mainly because of all that heat. If a compressor starts when it is allready sitting in an engine bay with an ambient temperature of atleast 60 degrees or more, its just going to reach its thermal cutout switch that bit sooner. Its like going offroad in a Toyota; your allready that far behind!

Heat hasn't been a problem in Pajero, LX470 or TD5. Even in hot desert conditions. Nor has sand dust or water.

MInes under the drivers
seat, as the last 2134 threads on it.
another option is under rear seats, or INSIDE the rear 1/4 panel.

I have
mine mounted under the bonnet opposite side to the exhaust
find it out of the way no probs with dust (comp has replaceable air filters)and makes it easyer to clean inside my cruiser.
I end up with enough stuff inside my car with out bolting stuff in.
But probaly is better for the comp in side the car.

Martyn,
Put it wherever you don't need the space. I find under the
seat a good place to store lots of things that I need in a hurry so I wouldn't put it there. Under the bonnet is fine if you have the space 'cos there is not much else to put under there. The only problem is dust in the fittings so just put a bag over them if it worries you that mauch. I don't bother and I have had
mine under there without a cover for several years and no problems. If you want to get really fancy secret mount it behind the trims in the back but that is a lot of work but looks neat.We have so little time to enjoy our land

Like a lot of the previous responses, I also have it under the passenger
seat of my GQ with no prob's. This location also makes it easy to add an extra air tank directly underneath next to the chassis rail with just a short pipe through the floor (sealed of course) between the two.

Buggeded if I know my super cheap model comes with it's own bag and will put 20psi into my patrol tyres in 3 mins flat, I hope i'm never in that big a hurry that I cant reach into the back of the wagon and get the compressor bag out.

Wal,
You are right, I suppose I just like the easy way, I've been stuck in rain when yes there has been a bit of a rush, and also when I've rolled a tyre the convenience of being able to plug the air line on and flick a switch has been nice, it all comes down to personal choice.

Mines under the bonnet on a GU 4.2.Turbo & I'm moving it. I recently stopped to help a guy at the side of the road after running at highway speeds for a while and the thermal cut out was hard at work. My last car GQ 4.2 with turbo had the same model compressor under the front passenger
seat and never had a problem.
As has previously been mentioned, it's also easier to reach the trailer tyres from further back in the car.
No there were no problems with dirt, kids feet or wives handbags and there was the added advantage of fart jokes for the unsuspecting mate.

I'm surprised no-one has suggested you chuck it away and mount up an old a/c compressor. Supposed to be mega fast, cheap as dirt simple to set up, etc. But that's probably a whole new thread........... Me, I've got the Blue Tongue under the bonnet - never a problem.

Likewise - Blue Tongue under the bonnet - fan cooled. I use a rubber grommet to stop dirt getting into the air connector.
Had it in the back before that - good location as long as you use substantial wires (say 8gauge) going thru to the back. These pumps draw the best part of 20 amps.
Best way to see what a difference voltage makes is to run the pump under load on one of your tyres, then start the vehicle up and note the difference an extra 1.5 volts makes. The pump pumps about 20% faster with the motor running.
