    Porsche Tyre Compressor?

    Does anyone here use the Porsche Tyre Compressor that comes with the 987 as their weekly tyre pressure checker and inflator?

    If so how accurate is it?

    I'm not sure I trust the local petrol station air machine, and usually some dick has parked there to go and buy sweets anyway, so using the supplied unit seems the easy option, but I'm not sure if it's something that's supplied purely as a "get me home" measure and isn't too accurate at measuring tyre pressures?

    Re: Porsche Tyre Compressor?

    I haven't even unpacked mine from the wrapper - i think of it for emergency only, plus the effort to get it out on a regular basis means you are better off buying another compressor to have accessible on the garage shelf.

    The pressure gauge on the compressors is poor and inaccurate - the dials are too small for any sort of accuracy. Buy yourself a half decent gauge, for around Pounds25 - seems a lot, but you'll soon get themoney back in tyre life using the correct pressures.

    Garage ones aren't half as bad as they used to be, but you don't know how they have been treated; people dropping them or even running over them with their car (yes, it does happen ) doesn't do much for their accuracy.

    Re: Porsche Tyre Compressor?

    Interesting - assumed it would be adequate tbh - possibly putting too much faith in the Porsche badge

    So of course the next question is what is a half-decent gauge? Looking on eBay there are lots of generic ten quid digital ones, so what constitutes a good gauge from the one built in on the supplied compressor?

    Re: Porsche Tyre Compressor?

    i bought a tanner racing one from - they are not the cheapest, but they are on my doorstep, so no issues with postage;x=22&y=12

    i'm sure you could find something similar via ebay.

    Re: Porsche Tyre Compressor?

    Just to say thanks - ordered a Longacre gauge from Demon Tweeks.

    Re: Porsche Tyre Compressor?

    From experience, I've found the digital gauges to be "better" than not. As far as your original question, I contemplated doing the same but the Porsche pump is pretty slow, with an iffy gauge, and quite loud. It's also annoying because you have to screw the lead onto the stem.

    Plus a service station down the street from me has free air.

    Re: Porsche Tyre Compressor?

    i got mine out, once...long enough to realize that if i actually had to use it, it would most likely take forever and never fit back in it's packaging....then i ordered a more substantial 12v compressor from griot's garage which looks up to the task....

    Re: Porsche Tyre Compressor?

    The longacre gauge turned up on Tuesday. Looks like one of those "should last as long as I do" items so Pounds20 well spent I think.

    To be honest the compressor is handy to have, but I don't mind bumping the tyre pressures up with a foot pump so long as I have something accurate to measure/bleed down the PSI with when they're done.

    Re: Porsche Tyre Compressor?

    actually thats the one i keep in the car in hopes i'll never have to use it...gave up on convenience stores for all the reasons here and rigged up a home nitrogen filling station
