If the noise goes once the engine is warm, it's likely to be the fuel pump.

Doesn't sound like the SC coupler to me, too regular and even.
Yes it could be one or both of the high pressure fuel pumps (there are two of them).
They sit on the RHS of the block (looking from the driver's seat) down low towards the front, one behind the other.
Get the car up on a lift, remove the rubber covers, and listen with an automotive stethoscope.
That said it could be SC bearing(s).

Car model, age, mileage and recent history of parts replaced (if any) always lead to better advice.

What solid coupler did you use? Many threads on this and the solid ones can cause problems.

2016 F type V6 66,000 miles oil changes every 3,000 miles and it just had full euro amp coolant system replaced with the oem eaton solid coupler.

Had the bearings inspected while the supercharger was out and they look good.

Take the SC belt off and start it, that will you if it's in the SC. If not take the main belt off and try it. Sounds like Idler pulley maybe.......

A few months ago, I replaced the factory supercharger coupler in my '16 F-Type (V6) with a genuine Eaton replacement coupler. I immediately noticed an increase in noise from the front of the supercharger. I removed and replaced the Eaton coupler with a ZZP solid coupler, and the noise went away. I have videos, pictures, and additional details in this thread: 2016 F-Type R - Supercharger Isolator

Eaton makes a different coupler for the V-6 and the V-8. Which part number did you install?

From my research on this forum, the AJ126 V6s and 2017+ AJ133 V8s both use a 49mm coupler (or 50mm, depending on how you measure it). The Eaton part number for the 49mm coupler is EAT-361506. That's what I installed and eventually replaced with a ZZP coupler.

The pre-2017 V8s would need EAT-85914. That’s a 47.5mm coupler designed for the Eaton M-90 and M-112 superchargers. ZZP also makes a 47.5mm coupler for the earlier V8 superchargers.
