777jonah888: +jlrmywork - changing the 3.8 inch pulley to a smaller size will spin the
sc faster creating more boost and power
Kyle Robinson: where can i find a aftermarket pulley for more boost? i have a 89 super
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 !
VF1Skullangel: Jesus Christ! I thought it was simple to remove these pullies! :(
God.Is.Love: Oh also, careful when swapping pullies. Most ppl ruin their car cuz they
drop it too low and dnt realize they have knock. Even some STOCK 3800 sc
cars come with a bit of knock retard. Make sure u have supporting mods
before lowering pullies. Some basic mods to help are...cold air intake, 180
thermostat, 104 autolite spark plugs, and either a power log or headers.
Power log easier to install but more gains out of headers...after all that
drop pulley if u have no knock. Typically ppl drop to a 3.4

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. :-),
Paul O'Neal: Autozone....
needzpower2: Intense, 3800, or zzperformance. I usually use the last because their
prices are generally lower.
SonyXplods21: how easy is it to change the rotor bearings in the supercharger intake
Melvin Brown: I have a 2004 Monte Carlo supercharged what size pulley I will need to get
me more horsepower
jlrmywork: 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: 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: more hp power,its best to swap the 3.4 pulley with ECM(re-cal).
zaklange: Wow didn't know it was such a pain in the ass to drop pulley sizes
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!!!!
bamfan2044: You could buy a Modular HUB from ZZP, then all u need is allen tool to
change pully sizes
SteveXnycperformance: its slick to provide will to create a earning,but you can also fall from
the slick. so balance your self herbalist.
SteveXnycperformance: from looking at it, it`s metric 8mm 24 thread per inch. 13/16 or 21mm 6
point socket for removal.
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
SteveXnycperformance: electric car,dude it the future.
javier rodriguez: is it possable to put a supercharger on my 92 oldsmoblie 88 3.8 v6 series
1? plz respond back thanks
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
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.
rd95stang: 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: yep. the plastic cap should pop out with flat screwdriver. Pulley will
SteveXnycperformance: The correct word is "slick" something you will never become Herb
SteveXnycperformance: 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
SteveXnycperformance: wait till you have to perform the removal and install with the S/C still
attach to the engine in its compartment(under-hood), it twice has hard.
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: MELVIONE4... I have a 04 monte supercharged as well. I wouldnt even touch
the pully without any of the mods i listed below man. U should join the
monte carlo forum if u haven't already. Ull learn a lot!
rd95stang: where can a tool like this be bought? i need to get one
jaejay716: I do not have a bolt on the front of my pulley. How can I get the pulley off
jcrow00: This is good stuff. Thanks for posting a video like this Steve. It really
helps me out. I just bought a Cobra and want to change the pulley on the
Eaton M112 supercharger.
God.Is.Love: Its always more of a pain to work on the engine and or supercharger with it
still being in the car. Better to take it out n do it correctly the first
time. Engine work takes time. To answer a question i quickly saw...changing
to a smaller pulley adds more boost which creates more horsepower. Every
car is different and results will vary mainly depending on ur current set
up. With that bein said every .1 u drop in pulley size is an additional
pound of boost. Around 5 horsepower extra id say.
MurderedA6Avant: freaking up the threads on the tool using an impact and could have heated it
up just a bit to ease it...
bearster1: Great Job on these videos by the way!!!!
jake josh: i wouldnt go any smaller than 3.6 on a stock engine.
God.Is.Love: All is it fairly simple to remove that button? No special tools required,
just pop it out?
MERLINSSCEPTOR: What is the thread size on the supercharger snout?
thecheesburgler: Good crap steve. Thanks for the upload.
Blake Albright: Where do you get a backing plate?
