Not at all worth it for the work involved. The gen5 is a great blower.
If you had a motor that wanted to see more than 15psi, then I would imagine you could see benifits from it.
Not at all worth the work???? Do you ever know what your talking about? Or do you just give people your opinions and tell them it's fact?
Lets see, it takes an adaptor plate, which is premade, a new belt, and you have to cut an extra groove in the crank pulley. Wow. That was soooo much hard work. O I almost forgot, you have to tune it too. But, nope, it's not worth alllllll the work you have to do.
If you want serious power, and have a built lower end that can handle the extra boost, and want that wow factor of having a GIANT supercharger on a 6 cyl, then yes, it is worth it. I will caution you though, it ain't cheap.

It's really not that expensive anymore compared to the total build if your REALLY into HP.
You WILL need to make that motor breathe for the MP112
You WILL blow stock head gaskets.
You WILL need to tune for it.
And it's a WORLD of difference from the M90
I think the only reason the are more GEN5 powered cars rather than MP112 powered cars is simply THEY CAME STOCK which would mean THERE IS A LOT MORE OUT THERE........................simply more #'s

That is an m112 hybrid, which is a gen3 m90 casing with rotors out of an m112. I would consider that slightly better then a gen5. To capitalize on any serious gains from that over a M90 you will need heads and a big cam. Running it with stock heads and cam, the motor can't flow the air it can move (which will dwarf the gains from having a bigger blower).
What are your other mods besides an intercooled m112 hybrid?
What are your 1/4 mile times?
How much boost are you running?

wftb, they are just different models from Eaton. The M112 was for larger motors than the M90 so they produce more displacement. From someone who knows nothing about SC, more displacement on the same size motor should produce more boost (higher PSI.) The crank and rods have to be able to take the extra pressure, or kaboom. The M90 was stock on the 3800SC that so many folks on the forum have swapped into their Fieros.
if your going to go for a cheep swap go genV if you want a bigger blower go whipple i know a guy that's selling a brand new whipple kit for the 3800II for 2,500 and it will kick the m112's rear in every categorie

Nice mod list. You are one of the ones that can actually use that blower.
I just think that the m112 is a waste of money for someone with a closer to stock set up and they could go faster with a stock blower and spending that money elsewhere.
Another friend of mine has a m112 hybrid also. I wouldn't mind haveing one myself

The M112 looks good and is better than the Gen 3 but like Dark said, the Gen V is a match for the M112. The pictures that Revin posted is of a friends car that is cammed, IC, ect that ran a best of 11.97 with a VS cam, it now has a XP. The fuel rails where made by the owner from just using stock fuel rail off E_bay. ZZP used to make the plates to make the M112 blower but stopped making them due to the Gen V being a match to the M112. This came from the mouth of Zoommer from ZZP to the owner of the M112 car. I cant comment on the MP112 that Intense has out, being I havent seen many ppl talk about them. If you want better blower, then go with the Gen V. If you want a better blower that is differant and you can find the plates, then go with the m112. If you have the money, then go with the MP112.

The M112 is a GenV. Then there is the M90 GenV and M90 Gen3.
If I am not mistaken the M90 moves 90cfm per revolution and the M112 moves 112cfm per revolution.
The M112 Hybrid is made from a M90 gen3 casing and along with a different spacer and snout and then the rotors of a M112. So yes, that would make it similar to the M90 GenV... Probably a little better.
The M112 Hybrid is not on par with the M112 that Eaton or Intense sells.
The fact that the M90 GenV comes on a lot of gm vehicles now, makes it a less expensive but nice upgrade.
I don't believe that ZZP is running a M112 (or hybrid) on any of their cars. Neither is Intense any more.

The only thing MOST people look for out of a blower, is efficiency. The m90 is efficient up to about 15PSI, that is when the air in the intake trys to push past the blowers. So if you have a setup that will support more than that, then the mp112 is a good idea.
Now, one nice thing about a bigger blower, is the idea that you can turn the blower slower, to get the same CFM, and that results in lower outlet temperatures. Being that the gen5 and the mp112 have near the same efficency, but the mp112 can handle making a bit more boost, around the 18-20 mark.
There is no doubt that the blower is better, but if you dont need it, then dont worry about it. I wouldnt hessitiate to go to that or a whipple, but I would have to have a very large blower cam, which could use 18-20psi, and the improved cfm. So with headwork, extensive cam work, and a low compression block, the mp112 works much better than the m90.
But, if your running a small cam, or another similar mild setup, then the m90 will supply efficent, low temeperature air for what you want in most situations. I think that revin could run close to what he is running without the mp112, but there is no doubt that it IS BETTER.
