SteveXnycperformance says:

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

everyone who knows has the tool. the thread always get fucked 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. :-),

Intense, 3800, or zzperformance. I usually use the last because their
prices are generally lower.

how easy is it to change the rotor bearings in the supercharger intake
assembly??

i just bought a 2002 buick park avenue ultra with the 3800 series II
supercharged engine and wanted to know what does changing the stock pulley
do for your car? sorry for the stupid question but im new to the whole
supercharger thing. thanks for your help.

jake josh says:

active in reverse? theyre vacuum operated so unless the BBVS steps in
somehow….. also do you know how many reverse donuts ive done??!? lol

SteveXnycperformance says:

more hp power,its best to swap the 3.4 pulley with ECM(re-cal).

zaklange says:

Wow didn’t know it was such a pain in the ass to drop pulley sizes

bearster1 says:

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!!!!

bamfan2044 says:

You could buy a Modular HUB from ZZP, then all u need is allen tool to
change pully sizes

SteveXnycperformance says:

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

SteveXnycperformance says:

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

bearster1 says:

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?

SteveXnycperformance says:

electric car,dude it the future.

javier rodriguez says:

is it possable to put a supercharger on my 92 oldsmoblie 88 3.8 v6 series
1? plz respond back thanks

God.Is.Love says:

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

Z34Phoenix says:

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.

rd95stang says:

thanks alot bro, i showed me exactly what i needed to know, i’ll be
ordering my refresh kit next week. where would i be able to order the front
pulley remover? thanks in advanced

SteveXnycperformance says:

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

SteveXnycperformance says:

The correct word is “slick” something you will never become Herb

SteveXnycperformance says:

It`s a lot of technical work, but it can be done.these car feature a
tune-port injection engine with a compression ratio of 9.5:1. the S/C
engine is 8.5:1. I would advise you perform a complete engine swap.the
trans will work but it software will need Re-cal. s/c gear ratio and
non-s/c ratio are not the same. save your money,buy a series II complete
from the yard and have it install is happiness. THK
