The 550000 is a much better unit, comes with adaptors to fit anything and is made out of solid brass rather than molded plastics. For the extra $20 or so (Amazon.com) than the $79 plastic unit, you have a much more flexible and long lived tool.................. It is also the same tool Porsche sells for over $500.....
We use these just about everyday in the shop, and on everything from 986/987's to motorcycles. And, no, the vacuum will not collapse the tank........

What kind of psi and cfm do you need from your compressor?

As it creates vacuum by air flow over an eductor nozzle assembly, it depends more upon volume rather than pressure. As such, any level of flow will do, the higher the flow rate, the faster it develops vacuum; but it always gets to the same level (24-27 inches). The manufacturer recommends at least 90 psig air delivery for optimum performance with larger volume cooling systems, such as Porsche’s. It is a neat tool, and it will pull a totally empty Boxster cooling system down to around 25 inches of vacuum in about 90 seconds, and then refill the system in about 3-5 min., leaving absolutely no air behind. And, as mentioned earlier, it will work on any cooling system. Real time saver around the shop and no “come backs” due to trapped air or coolant levels dropping later.

Yes the cooling system is a little odd. Crazy Germans. Remember that Porsche has been building air cooled motors for over 60 years and the 986/996 is essentially a first generation water cooled flat six production motor so we are guinea pigs to some extent. Chevy has been doing water cooled motors since 1914?? so by now they have the bugs worked out.
Do pay attention to purging all the air out as air entrapment and hot spots in this motor mean cracked heads or worse.

I guess what I'm really asking is how big of a compressor and tank do I need to run this. Mine's kinda small - great for filling tires and blowing off dust but not adequate for most air tools.

I've seen people run them off rather small portable compressors, so it can't require all that much. Other than the recommendation for 90 psig, I'm not aware of any other requirements. You may want to drop them an email as I'm sure this question comes up all the time........

I borrowed a small 8 gallon unit, and it pulled the required vacuum no problem. A smaller one would likely work too, just would take longer to evacuate.

RR, I live in a city with a pop of about 700K. Just Googled tool rental and found 18 places I could rent a compressor at a fair price. I looks like your in the UK and would think there it would be about the same. You might find someone who has a compressor but no bleeder and do a loan.
