Smallest/most compact belt driven air con compressor

[Slippydiff]

As per the title. Have you seen/noticed a particularly compact air conditioning compressor ?
I’m looking for a small diameter and short/stubby air con compressor to fit in a small space due to a change of inlet manifold.
Due to packaging constraints there’s no other location available. Period.

Current compressor is a Denso item :

Dimensions of the current unit can be found in the description.

Are you following 'Project Binky'?

[Slippydiff]

Yes I have, and I marvel at their ability to find seemingly increasingly complex solutions to simple problems !!

My comment regarding there being no alternative location for the compressor was made with good reason, there is quite literally no other place it can go, so a flexible drive shaft such as they’ve used isn’t an option unfortunately

Something electric powered rather than belt driven? Would that open up new packaging opportunities perhaps - thinking Nissan Leaf used compressor for example.

As mentioned above, electric may be the way forward

Thank you, I had considered the electrically driven option, the problem is they draw a pretty chunky amperage. So much so it’s been suggested the charging system would need uprating. The current alternator whilst up to the job of powering the current ancillaries, probably won’t cope with the 20-30 amps the electrically driven AC compressors typically draw...

What car are you working on, what electrics does it have?
I'm thinking....

2000 Porsche 996 GT3 fitted with a 2009 997 Cup engine.
The Cup engine utilises the inlet manifold from the 997 4.0 GT3 RS which contains two resonance flaps. One is operated by a vacuum actuator which is situated exactly where the A/C compressor is located (Cup cars don’t have aircon ...)

Current charging system: The road car variant uses a 120 amp alternator, I thought the Cup item was smaller, but in reality it looks a similar size to the road car version, but I'm not sure what its output is.

Thinking WAY out the box... Drive the AC pump from a driveshaft? - It would give the excuse to say the words "Sorry I did not stop officer, I was hot and wanted to cool down"..

You should be able to upgrade the alternator with parts from another old unit if cost matters, if it's a Bosch there should be plenty of high output ones knocking about a breakers yard
