With Electric AC and a High Amp WOSP 175amp Alternator I have been plagued by V Belt slip when the AC is at maximum. I have used an idler to get more belt wrap and now a slightly larger alternator pulley. Use a Poly V belt or tooth drive if you can. Note I have a tooth belt drive set up from Croatia on my bench to work out how I make it work. The crank pulley is 28 tooth not 29 like a VX crank pulley toothed pulley so I will have to have a toothed crank pulley drive made to run the alternator WP and Volumetrico SC. Alan Young Engineering for this. If you are not using a VX or Volumetrico and have no need for an ECU trigger disc mount it is a great solution. I have some engineering drawings to do!

Took me a while to find this post Eric but I knew it was there somewhere! A frustrating couple of weeks with the sun visor trimming proving to be beyond my capabilities so I resorted to a professional, hope to get them back in a week or two.
I am getting to the point I need to start looking at the motor and gearbox so.a few days tidying up the garage and getting rid of dust and dirt. An engine stand was ordered (cheapie £45 one) from a UK eBayer but when it turned up the box was damaged and the wheels were missing. So, UK supplier, simple quick replacement. Nope. Turns out the wheels are coming from China and taking a while. They'll pitch up when I'm at Gerry's next week.
I've ordered a set of cogs for the water pump, alternator and crank with a toothed belt so I shouldn't suffer from belt slip there as per your recommendations. I assume I get them for the same supplier you did?
https://classicperformance-parts.com/product/fiat-124-131-132-ritmo-lancia-beta-delta-engine-toothed-pulley-kit-2000/I think I'm going to see the wiring folk mid May to spec the system and discuss the size of the alternator I'll need to keep the car happy when the air conditioning pump is running. Then I need to source it - either a 175 or 250 amp one I would guess? Wosp probably as they list both for the Beta but finding a supplier may be an issue! Also need to consider water pumps, I'm not sure what's in the engine at the moment but there is a NOS one ready to go but it's a standard one and not a VX/Montecarlo one. That's probably a worthwhile upgrade at this point too?
