I have read all over the place that the GMPP SC for the Z24 cavs 00-02 is based off of the Eaton M45 Blower.
But i just recently found out that the M45 came in a P flavor as well... i guess the M45 is the 3rd generation, and the MP45 is the 4th gen.
looking at the 2 side by side... my GMPP SC looks nothing at all like either of them. So cant really make the call on my own.
Hoped someone else would know this.
When talking to the guys at an SC shop, they kept refering to "removing the blower from the intake" but looking at mine, i dont think that is possible. and that is further confirmed by the way gm describes it as an "integral 'roots-type' supercharger and manifold design ".
There is only so much info out there on this GMPP SC... but lots more is out there on the general eaton SC's... so just hoped if we could find out exactly what we have here, we could learn a lil more about them and how to improve things.

Gm cast the m45 as aprt of the manifold so that is what makes it an oddbal from almost all other sc where you just unbolt it from the manifold.

Ok so you are sure it is indeed the M45 3rd generation?
because it looks like the MP45 had alot of improvements done to it (mainly the fact the MP45 claimes to be S-Ported from the factory)
Model M45
The Eaton Model 45 supercharger was
engineered for 1.0L to 2.0L passenger cars and light truck engines. It was designed as a compact, flexible supercharger for increased power without adversely affecting fuel economy. The M45 has proven to be suitable for other engine sizes depending on overall system requirements.
Model MP45
The Magnuson/Eaton Model MP45, 4th Generation is a “State of the Art” supercharger,
engineered for 1.0 to 2.4 litre port injected engines. It was designed as a compact, flexible supercharger for increased power with original equipment quietness and reliability without adversely affecting fuel economy. The M45 has proven itself in a number of applications, and this latest version has taken this stamina and versatility to the next level
with “S Port” technology and a built in bypass for unparalleled performance.
here is a link with some specs and pics on the 2. neither one looks anything like ours... I would have to pick the MP45 based on looks alone.... but that is why i am asking....

I dont want to pay $400 for S-porting if we have the MP45 and it is already ported...

I do not know what generation it is for sure.

Without clicking the link, does it even describe what "S-porting" is? For all we know it's nothing more than just a fancy pattern cast into it

Taetsch,
You sure about this, and how do you know?
I was about to pay a good heap of money to have mine "s-ported" but if this is indeed a MP45 then it is already S-ported....

ive heard quite a few ppl call the ld9 gmsc the mP45 as well as just the m45.
your knowledge suggests the mp45 ppl are wrong.

hmmm no sarcasm there....
I think it is a pretty reasonable question. No one else seems to have the answer to it... So with your response sounding so certain, it is well within my bounds to ask your qualifications. Are you an engineer for GMPP and helped design the thing? Or did some guy at lube stop tell you this while he was bragging about his station wagon that can beat a Z06.
I dont doubt your knowledge or skill, just curious as to how you know this, where you found out, or how reliable YOUR source was. It obviously is not information that is readily published or proven.
I have people on this board telling me that "s-porting" is a matter of drilling 2 holes near the exhaust port of the SC to increase flow, and that they found this out online.
And then i do some research on that, and find websites online talking about how to S-port, and they say to fill in the 2 holes by the exhaust port if you have them.
i am sure both people were knowledgable in superchargers, and in the cars they were working on... but obviously someone is wrong there.

I just posted up what I found off some random site that seemed legit, I hardly looked into it, don't know anything about this "s-porting" so don't take my 30 second research as true, lol.

Chris Taetsch works for a GM dealership in the parts department. He aslo has had the sc on his car now for longer than most of us for sure. There is no doubt he is familair with the sc kit and many other gm related parts ect. I will let him speak for himself though about the m45 mp45 thing.
I don't know if he was offended by your ? or if someone pissed in his cherios yesterday or if he was just being a smart ass or what but he is usually a preety cool guy. I was a little surprised to see a response like that.

I was kinda mad. but it is a 4th gen blower.
you can ask MCFly. i have worked with mangason ....alot.
one tell tail thing is the snout. it looks different between the two.
the "holes" that are in all MP chargers are for DRIVABILTY. with this comes SOUND complaints. the holes are there to make the supercharger quieter.
i have never really heard of s porting (other than read it here and seen it one or twice before.) but if a place like stegmiers does it, or Eaton, or mangason, then its good. if not..... i wont do it.

Well... i think you are right on all points....
the snout for sure looks way more like the MP45 than the M45....
the guy i refered to as "filling the holes" talked about them being for noise muffling, at the cost of some performance... and thus why he filled them....
and s-porting is something all the supercharger shops are hyping as the best thing you can do short of getting an MP90.... it supposedly increases flow, reduces parasitic drag, and lowers temps... they claim it is a huge performance boost and well worth the money.
sadly... if what you say is right... (which so far you have been) the MP45 comes S-ported from the factory... so you cant "have it done"... and i was all excited to see how much better it would be.... but damn it if i dont already have it.....

I have Chris's old SC and he has helped a lot to get it to where it is at now. Only thing I have done since I owned it was pickup a new nose drive and sent it to Steigemeier for porting. Steigemeier told me it flows 20% better than stock, but did not provide me with any numbers to back it up

Well, i hope they didnt rape you.... because if Chris is right, and the GMPP SC is indeed a MP45... it is already S-Ported by eaton from the factory... so hope you didnt pay too much money to have them do something that was already done.
read up on the MP45... that is its main bragging point... it is already S-ported....

I was about to drop $400 on an s-porting before i relized mine already has it.
I would call them and have them prove what they did made a difference, or ask for your money back....
they may have cracked that thing open and been like "well.. ok.. look at that, job well done, that was a damn easy $400... call this guy back get his payment and tell him we finished it early"
