Wierd noises from sprintex supercharger

Hi
New here
I have 2012 toyota gt86 with sprintex kit on it. I bought it with the kit on it and ever since then the engine bay make squeaking noises , probably belt/pulley noises.
First inspection showed that the accessory belt tensioner was not working right so he got replaced with a new one, but the noise is still there.
Ill try tomorrow changing the drive belt since i have a spare one at my garage, but she looks perfect, no signs for cracks or anything.
Im starting to think the noise is from the sc pulley , is it possible to oil him a lil bit ? Mabey he making this squeaking noises?
Does anyone faced the same problem ?
Thanks.

Have you changed the gear oil in the supercharger itself in the time that you've owned the car?

So i did some research and bought redline 75w90 ns gear oil , changed the sprintex oil that was almost empty !
Changed the drive belt also , and now everything seems to work perfect. No noises at all.

Thanks !

Sprintex kits are every 30k but when pushed I have read the seem to loose a bit oil. Most people recommend checking the oil level regularly and it must be jacked up to to get a level reading.

Mine is making weird noises too. Ive attached a video which distinctively demonstrates the sound I'm referring to. I haven't gone to a shop to have it looked at yet but Im thinking this a pulley bearing on its way out (not sure which one)
This noise completely goes away once the car is warmed up. Does anyone know what this could possibly be?

Are you talking about that squeak? If so it's the belt. What pulley do you have? Mine did that for a bit after I switched to the 69mm from the 72.5 but it's gone away. Get a spray bottle of water and use to lightly spray the belt. If the sound goes away might want to put a fresh belt.

Hey thanks for the reply
Yes I'm referring to that squeak lol
I'm running the 69mm pulley since I had the SC install. I just got this supercharger + pulley/belt a few months ago. Is it possible I need a new belt already. I dont track the car... just daily drive it and occasional pulls nothing crazy. It's hard to believe I need a new belt already but I will try your suggestion.

Try this. The stock one will not work as you drop the down to smaller sc pulleys

I ran one of these kits for 62K miles. I'd recommend checking the gear oil in the blower on a very regular basis, it will consume oil and if it goes dry bad things will happen.
