Start off by taking a 15mm wrench and slowly depress the belt tensioner. You need to do this slowly to allow the small shock absorber to compress. If you go too fast or push too hard then the tiny piece of metal on the tensioner will round off.
NOTE: I later found out that it is actually easier to use a small pair of vice grips.


Next remove all obvious electrical connections and the 4 bolts that hold the SC on. You will need to use a long HEX socket bit for those. The one on the top left is the hardest to get to because of the fuel rail. If you have a sturdy T handle and a strong wrist you can take it off with that too they arent torqued down very tight.


Lift the blower off the intake manifold and remove the connection for the throttle body. You need to take the small grey clip out before you can remove the plug. Then cover all areas that you dont want critters to get in. I used 3m painters tape.


This is optional but reccomended. Take a small hex key and remove the SC oil drain plug. Tip the SC upside down and rock it back and forth until the 3.4oz of oil comes out. I'd like to thank Holiday Inn for the use of their cups This will also help avoid and surpise messes should you screw up the next step.


New oil VS oil with 35000 miles on it. Stage 2 for 20000 miles.


Then remove the black bolts holding the main housing from the rotor housing. CAREFULLY pry the two apart. My massive german finger is pointing where you should pry. If you should happen to separate the other piece all the SC oil will dump out. Then slide the rotors out slowly and place in a safe spot where it wont fall down and spill oil all over the carpet. A wobbly table is a bad place.... Whoops .

If you are feeling lucky you can just score up the area where the quicksteel will be with some sandpaper and or scratch it with a small pick. I took a dremel tool and beveled the inside of the silencer holes so that he plugs would never fall out. After that cover the holes with tape. Then knead (just like dough) the quicksteel into the hole. Press your index finger on the rotor side and knead the quicksteel in with your other hand on the manifold side. Make sure that the rotor side matches the contour of the housing and is as smooth as possible. After the Quicksteel has set (10 min) you can sand it down if you need to. Before sliding the rotors back in clean the blower out with a can of brake cleaner. But be careful to only spray it through the throttle body side. That stuff will dissolve the grease in the bearings!


Wait an hour for the Quicksteel to fully cure before reinstalling SC. Fill the SC up with oil while waiting for it to cure. 3.4 oz of oil ONLY. Reinstall the SC and enjoy the new whine! Oh yeah it boosts a little faster too but who cares about that? MORE WHINE FTW!

Another note. Before using a dremel tool or sanding it is wise to cover the small grease covered roller bearings with some tape. Getting small metal pieces in there would be bad mmmmkay?

 

I changed your links to pictures. It looks like you are missing one.

 

yea soudns like ur missing a pic or two lol....nice write-up thoe

and can you get a pic of what you mean by beveled the silencer holes please??

 

Crap. I did miss a pic. I'll update this soon sorry. Rushing FTL.

 

Um, Oil should be 6.0oz total..... That's a major component of longevity of the blower's bearings. Only 3.4 may come out, but if you crack the casing open where the snouts internals are you need to drain out as much as possible and replace it with 6.0oz

 

I love how loud mine is now but am deff interetested in making it louder! Hopefully you can get the rest of the pics up and I'm gonna give this a try. Good write up man!

 

6oz is too much.

Good write up Paul.

 

Hmm. The three stock ones I've torn apart and rebuild all had >than 100cc. They were all nearing 200cc of oil

 

TRUTH! tilt it on it's side and fill it up to the bottom of the fill hole.

I also am a crazy bastard so I put ~1oz of lucas additive into my blowers.

 

Unfortunatley I forgot to take pictures of the beveled holes AND after I put the quicksteel on. Pretty much just grind off a small amount of metal on the rotor side of the silencer holes to a 45 degree angle.

I didnt want to add any more than came out. That way nothing was changed at all. If the oil is supposed to last the life of the car obviously its not going anywhere anyway. So i'm sure none if it "burned off". Oh you mean mL not cc right?

Thanks buddy

 

ml = cc. Sorry, I had work stuck on the mind and should have stuck with ml. But 1cc = 1ml.

 

awesome write up.. i have a couple questions though.. you said its optional but recommended to remove the sc oil drain plug.. do you have to refill the sc oil after you take it apart to fill in the silencer holes? sorry, im a noob at this stuff. and where did you buy the quiksteel from? and aso, you said: Then remove the 874 bolts holding the main housing from the rotor housing.. what are 874 bolts? i want to do this so bad but im afraid im gonna mess something up lol

 

You can buy the Quicksteel at Advance auto parts or Pepboys. You only need to refill it after the blower is all put back together and ready to be reinstalled. I only drained it as a precaution in case I accidentally separated the snout pieces. The oil would have dumped out all over the hotel room floor.

I was being sarcastic about the eight hundred and seventy four bolts that hold the snout to the rotor housing. There is only 10 or 12.

did you do this at a holiday inn?

 

I swear his answer better be "I'm not a mechanic but I did stay at a Holiday Inn Express last night"

 

Reason number 58 why they require a credit card to stay at a hotel

 

Thats awesome! I did do it at a Holiday Inn lol

 

Just a note - doesn't GM (and Eaton, and everyone else) recommend 6 oz of oil? This is the first place I've ever heard of 3.4 oz. >_>

thanks again for writing the how to.. i plugged my holes and its definately louder.. i cant even imagine how loud its going to be when i get my 2.8 installed lol

 

Is there any horse power gains to pluging the port h
holes?

 

No...just more whine.

 

3.4 is what came out. And 3.4 is ALL that i'm going to put in. Nothing was changed inside the blower that way.

Miniscule if any. Just like a Honda with an intake. It sounds faster lol.

 

thanks for this man i did mine last week it ****** screams now.

 

Glad you like it!
