777jonah888: +jlrmywork - changing the 3.8 inch pulley to a smaller size will spin the sc faster creating more boost and power

StevexNYCperformance: from looking at it, it`s metric 8mm 24 thread per inch. 13/16 or 21mm 6 point socket for removal.

StevexNYCperformance: its slick to provide will to create a earning,but you can also fall from the slick. so balance your self herbalist.

StevexNYCperformance: The correct word is "slick" something you will never become Herb

StevexNYCperformance: 3800performance

Z34Phoenix: there is no key slot on the standard m90. the manga charger that is sold on some sites does have special keyed pulleys though. but these are rare.

Paul O'Neal: Autozone....

StevexNYCperformance: yep. the plastic cap should pop out with flat screwdriver. Pulley will required tool.:)

God.Is.Love: All is it fairly simple to remove that button? No special tools required, just pop it out?

StevexNYCperformance: It is possible,but the fuse/relay plastic box will require removal.Plus the Coil pack with bracket will ease removal.It not easy to preform on a car,if u do so please be assisted by someone else. it is not possible to use the power tool while working on the car. the single snout bolt (copper filter) might not be equip on all s/c application,instead, a plastic button might be in place.

God.Is.Love: Would that pulley puller fit while supercharger still in car? Also, I dnt have that bolt on front of the snout either

StevexNYCperformance: When you remove the belt.Use your hand and try to move the pulley back and fought in all direction.. them you might be able to identify the noise

bearster1: where am I gonna find that replacement pulley ??? THANKS !

bearster1: also, is there a key and keyslot on the pulley and shaft or is it strictly a taper fit with the vented bolt applying all the tension to keep it in place? maybe why you are changing it out in the video LOL!!!!

bearster1: Great Job on these videos by the way!!!!

bearster1: Mine is making some noise, chatter and it is hard to verify but is seems as if the pulley, there may be a very small amount of slippage on the shaft. I am going to attempt to tighten the vented bolt although I think that if there is wear it is not gonna get better. Is this the reason for changing the pulley?

jaejay716: I do not have a bolt on the front of my pulley. How can I get the pulley off

StevexNYCperformance: everyone who knows has the tool. the thread always get freaked up after a few sway.With the hub system the tool is only needed once,THE SNOUT BEARING SHOULD BE REPLACE AT THE SAME TIME WITH THE HUB SWAP. :-),

MurderedA6Avant: freaking up the threads on the tool using an impact and could have heated it up just a bit to ease it...
