I'm hoping the one I ordered is the right one for this pumpYou could use the low vacuum warning sensor from a Nissan Terrano. It puts the dash light on when the vacuum drops below a preset threshold, but I imagine it could drive a relay to power the vacuum pump in the same way.
Just a thought.
There must be a vacuum switch to control the VAG pump you ordered.
You have to love anyone prepared to Resto-mod an Allegro with a supercharged 2.5 litre KV6!
He's brave making a silly power Allegro, although it looks like a Honda C27A engine to me.
The Honda C27A was a really reliable engine, but the KV6 was more powerful, lighter, and more efficient. Oh and sounds better IMO too.
Unfortunately electrifying a classic car is seen as a luxury item, so these companies are charging a premium for the work. They're using exotic and expensive components to justify the cost, which seems OTT to me.
Sweet!Excellent stuff Ali. I'm going to spend some time on the coupler over the weekend too, and post some pictures, once there's something interesting to show.
When you really need them buy them. That's how I get all my tools and there are still loads of things in my wish list.I need to get a set of transfer punches Ali. A set has been on my wish list for years, but there's always something else that comes along which takes priority.

It's not worth it, as they'd need to be made of tool steel. Tool steel then needs careful heating and cooling, for it to be hard enough to use as a punch, but not so hard it shatters when hit. Tool steel blanks would also cost more than buying the punches to start with.
Heat and quench only works for steel that is already a hard grade, O1 or D3 for instance. These steels are very hard, but supplied in an annealed state for machining. Once machined, they then require careful heating and quenching, to bring them up to full hardness.
