Ok, time for my second how-to. Sorry it took so long to make it. Lets get started...

First you need a dremel, 6mm allen bit to remove the blower from the intake manifold. Then a (I'm pretty sure) 10mm wrench. Thats about it.

Ok the black bolts on the front of the blower, I think theres like 9 or whatever. Anywho, they need to come out.


Then there is silicone gasket maker holding it together. Theres two surfaces held together by this stuff. The first is the surface between the snout and gears, and the second is between the gears and blower housing. VERY carefully pry the gears away from the housing, by doing it this way, you won't have to reoil it. Just don't jolt the snout/gears and rotors assembly, if you do the silicone seal might break and oil will leak all over.


The bearings are in the back of the housing, if you just put tape over the openings you shouldn't have to worry about them.


I used a high speed metal cutting bit for taking the material off the V port on the bottom. I took more material off than anyone else I've seen yet, you don't need to take that much off to get a difference. This is the "V" Port I'm talking about, if you want, you can take material out of the little slits, but I didn't touch them on mine.


This is the bit I used to remove the material.

I only used 5 through the entire process, because after a while the bit would get clogged up with pieces of metal, but instead of throwing it away, I would use my knife and pick the pices out of the teeth, and the bit would be like new again I used 5 so me or my friend could grind while the other cleaned up a used one.

After I was done with that I used a few of these bits to take the sharp edges off where I was grinding.

Then I removed material and smoothed out the ridge that just disrupts air flow on the inlet. This is the ridge you need to smooth out.


This is the bit I used to do this.

Then last but not least I used one of these to polish up the inlet and clean up the outlet.

Afterward the outlet should look something like this, but keep in mind I took out an insane amount of material so you might take out less than I did.


The inlet after smoothing out the ridge, and polishing it up, should look like this.


Then clean it up, bolt it back together, and bolt it on the car. Depending on how much you ported it, you may have to retune the car due to increase air flow. Now your ready to scream like a banshee, kinda like my car

I want to give a big thanks to Mike (SwizzDSMSS) for all the help with porting mine

 

wow, great write up. this will surely help a lot of members.

 

ill agree, great write-up. now, if i could had the ability to tune my car, i would port mine and insane amount too!

 

THANK YOU!!! DC your my HERO!!!
The other mods are so LAZY!!! Took a damn week to get this thing up!

 

i wouldn't say that we are lazy. we are oblivious when these threads are created and waiting for approval. if there was a way that we can get an email regarding a how to thread then we can go to it and approve it quicker. we get no sign that these threads are waiting approval so that may be a reason why it takes long sometimes. i suggest people PM a mod or if you can report the thread that way all of the mods get an email so they can view it and approve it quickly.

 

Nice how-to man. I've been wanting to do mine for a while now. I have all next week so I might give it a try, when I de-winterfy my car. She's sick of sporting the bigger pulley and 16's.

 

Does it matter which order we tighten the bolts of the snout back on in?

 

how long did it take start to finish? i.e. from taking the blower off the car, to doing the job, to reinstalling the blower, to the test drive?

any tuning involved? and if there were any snags or good things to know before attempting this?

thanks in advance

 

interested in doing this i would like to know about the tuneing also

 

It depends on the level of porting. If you massivly port the thing, then yes you'll need to re-tune. Just a mild porting, you shouldn't have to re-tune it.

It took a while to do it, it does because your grinding material off a metal peice.

 

thanks for writing this up.

 

just an observation, maybe obvious, but...it seems like when you take the snout off, if you clamp the piece that is supposed to come off with it onto the snout piece itself, that would help assure no oil leakage out of the snout.

 

Well, since Its good business, and I'm totally broke 99% of the time. I'm offering to port your blowers people. Concidering Steigemeier charges like $350 to mildly port a blower. I charge conciderably less. Please PM ME for prices. I already may be porting someones blower from New Jersey, and I have 3 locals lined up. The more business, the easier it is to make my car payment!

 

if i port my blower... probly a little tiny bit less then yours do you think itwould be safe to drive it about an hour to get a tune? as long an i dont beat it.. so i can port my blower b4 i get there an then add the 2.6 an 60ers when im there... thanks man an awsome how to!

 

What if someone was to slightly break the seal on the gasket that holds the oil in the snout, how would one go about sealing it back up? I need help asap on this as i'm going to install this tomarrow as soon as i get off work.

 

You also might want tto re-grease the bearings while your in there, and use brake cleaner to clean everything up, also you should re-seal it with the rtv sealant.

 

Alright....I know this helps with airflow but how much of a difference are we looking at here

 

umm.... I see a lot of "My blower is making f'd up sounds" threads in the future..
work to the wise. If you've not had experience in this type of work, or really don't what you are doing. PLease do not attempt this.
This goes for you L.I. people too, I"m not fixing your damn car if you f' it up anymore for free.... after what Inhale did to me.... labor ain't gonna be cheap

 

I don't think we are going to be able to put a rating on this because its mostly about the sound of the supercharger than the HP. Yes it should help a bit, but our blowers actually do a pretty good job of moving air. I'm gonna do mine mild!

 

Go tp Wal-Mart and and buy a tube of RTV Red High Temp Gasket Maker, and use it sparingly, just put some on your finger and spread it around thin, you are not caulking a bath tub.

I've done 8 blowers in the last 2 weeks, and I have more more lying here to do.

I will be posting my own write up shorttly because I have some more pictures that might add to the usefulness fo this thread.

 

Nice howto! Anyone know what kinda gains? And doesn't porting the blower lower IAT2 temps?

 

Now there is a screw on the face of the snout is this were i can drain and fill the snout with SC oil?

 

nice write up!? do i think a first timer would be able to handle this?

 

Dude, your car sounds bad as FSCK! I love it!! My buddy, who unlike me has tuning experience, just got HP tuners so I see project for my SS down the road!!

 

If your a first timer with great mechanical skill youd probably do alright . Imo its not hard , u just have to be disciplined . Its easy to slip and metal cutting tools arent forgiving Buy a small piece of the aluminum plate at the hardware store and practice on it .

Nice write up Cam .
