Has anybody fitted an engine driven air compressor to a petrol GQ Patrol. I have seen a few on toyotas and they fit nicely, but under the bonnet of the GQ there dont seem to be much room ? Ta

Cameron do you mean electric compressors, wired in and mounted in the engine bay, or one actually driven by the engine? If you're thinking electric, there are a number of portable units which do the job very nicely. Mine will bring a cruiser tyre from 15 to 25lbs in 3 minutes or less.

I think he's talking about the modified air cond compressors that are belt driven from the engine and will inflate tyre from dead flat in around 1 minute.

Fred I am talking about belt driven compressors. I have seen some kits around, but they dont fit straight into a patrol. Also a friend has built his own from an air conditioner, but that was in an 80 series cruiser

Sorry to have doubted you Cameron! I just hadn't heard of that being done. Seems like a lot of trouble to go to though when the portable units are available albeit a little slower. I'll be interested to read how you get on with it - sounds like a good project!! Good luck with it!

Hi guys i have an on-board air compressor made from an aircond comp, it cost me $20 for the comp and about $60 on all the fittings, i fabricated a bracket to fit on my MQ diesel, i used a 1000 psi fire extinguisher tank for air storage, a pressure switch, water seperator, ect. you can check it out on my site.

Thanks for the link steve. You seem to have a lot more room in the MQ. There are kits for GQ diesels, but no-one seems to have done it on a petrol (dual fuel) GQ. Anyway, how much air do you need !!!! Thanks

cameron a mate of mine does have a petrol GQ and has the same problem the only way we think one would fit is on top of the air pump, but it is not easy which is a shame, he is probably going to get an electric one. How much air do you need well most air compressors have about 1.5 cfm which seems to do the job they will do 4 tyres from 15psi to 35psi in about 15min's with a standard size tyre (31x10.5x15) i have 33x12.5x15 and it will do it in about 6min's using a 9ltr air tank, more air storage is really for the use of air tools.

Thanks steve. When you say on top of the air pump, is this between the air con pump & the alternator? I had thought about putting something above the alternator, and running it off a third pulley behind the fan, the problems are how to mount it out there and also that it is a long way from the block and might move too much. The top mount could come off the thermostat, but the bottom mount is a little more difficult to imagine. I would be interested in hearing what you friend does. I have an electric compressor (ARB) that we use on the trailer (it runs on airbags) and have already had to rebuild it after about three years. Also electric compressors pull a lot power out of the batteries (they can pull upto 25amps when running)

Cameron i am talking about a 3 ltr petrol, if your talking about a 4.2 ltr i'm not sure about them, from memory the 3 ltr has an air pump for the clutch assistance and i think there is some room above it yes you would probably have to use a small one though. I will let you know about what he does when he does it and i will be able to email you some photo's of it.
