I've actually seen that one before. Pretty neat. I've been considering switching to the R35 sensor and designing a custom housing for it to really keep the airflow as optimal as possible, but the Z32 one is currently working great and I don't want to mess with success.
I had to work out some 3D printer challenges, so I'm hoping to have some updates on the CAS bracket soonish.

It's soonish, and I have an update, albeit sort of a frustrating one. I was able to weld up the gear from PCBWay with no issues:
There was no drama. I clamped it firmly and welded in a few places, and the warped trigger wheel straightened out reasonably well. It could be a bit straighter but I don't think it'll be an issue in real life. Unlike VR sensors, hall sensors are quite forgiving.
I also sorted out some 3D printer maintenance and was able to print this bracket. It's in PETG (PC is stiffer but is finicky to print, so PETG is what I'm using for all the prototypes). If I grasp it firmly at the sensor end and push I can still flex it, but I think in application the amount of flex will actually be very minimal. Especially since there's no force on it front to back in real life.
I bolted it up (well, zip-tied) on the Turbo II engine to test, and everything looks pretty good:
Clearance to the trigger wheel looks good.
All the pulleys still clear.
Another view of the PS idler pulley still clearing the bracket even at it's lowest adjustment.
Clears the water pump pulley snout.
Clears the water pump pulley face.
So overall everything has gone really well. Except for the minor snag that it doesn't fit my S4 engine currently in the car, so I can't actually test it. It turns out the S4 water pump snout is different and so is it's pulley. The bolt holes line up but the centering bore is different. The actual snout is also in a different place relative to the water pump housing, so it's a bit closer to the crank and my pulley won't bolt up.
In my defense, the water pumps look nearly identical. I think it's only a few millimeters difference. But it is enough that I can't actually test. So for now I'm driving around with a prototype (using my old trigger wheel), but I can't actually test the new design until I swap engines.
I should have another update in a few days which you guys might find interesting. Until next time
