Hey, put a 4AGZE in my Mk1 cortina and just started it up today but the supercharger went *clunk* then stopped being a supercharger and started being a nothing at all.
I had the supercharger (SC12) off last week and was spinning it by hand just fine. I was turning it to make sure it hadn't eaten any bolts or such during it's dormancy and it seemed in great shape. So I'm baffled as to why it stopped on me today.
Is there something obvious I should know about the clutch at idle? I wired the Link to turn it on at 1500 so I can idle clean, it should still free-spin below 1500 right?

On the 4AGZE the supercharger is activated by sensing load from map/afm/throttle and not by rpm.
Can you turn it by hand (you can do it by turning the clutch part while the engine is off)?

Sorry should've mentioned, it's running a Link. The clutch is enabled via a relay and set by RPM in the Link EMS.

Oh Novus! Yea, Im thinking this must be what's happened since a bit of grit it'd eat no worries. That's why I posted because I can't think of anything else that would've made the SC just stop like that other then it eating a lump of metal. If it's irreparably shanked Ima get me an SC14.

An SC14 will need a bit of custom work, doesn't bolt straight up.
Motorsport is like sex. You could take it to track and have a long, enjoyable session, or you could take it to the strip and get it over with in less than 20 seconds.

There's a bit of alloy that mounts onto the SC which you plumb to the IC. It's held on to the SC by 5 bolts. If any of those bolts are too long they stop the SC blades from turning.
Also, the large rag stuffed in the IC pipe wasn't helping
