Can anyone tell me based on the attached photos if the tension on my trd supercharger belt is correct ? Iv e been looking all over the site and i cant find how much tension should be on the trd supercharger belt. Ive got about 100k on my blower and im not sure if the tensioner is going bad. Ive got a squeel coming from the top 3 pullies i cant nail down. Im attaching a photo to show how much slack but its a little over 1/2 an inch and i can twist the belt about 10% more then fully sideways. If it is the tensioner would you know the part # ?.....

I would say replace the tensioner. 100k miles is a lot for something like that.

Definitely looks like too much play in the belt. Especially how you can twist it like that in the first pic. Mine is much tighter, putting in my third belt due to belts showing cracks (third belt in 65,000 miles. Never had slipping issues or squeaks with the toyota belts. Stick with toyota OEM good prices on Amazon. Could be wrong belt size.
