The first link does not show any info that it is an m112 on that site. I have done a ton of research on this matter before and came up with nothing. I see alot of "talk" on these forums, but i never see any proof of this. Half of the internet says that blow is a m90 and the other half says its a m112. I check up on eatons history and they say the first ford used eaton m112 was made for the ford lighting, then the 2003 cobra. Nothing in there says anything about the svo blower. If you have like a parts number or something of ford saying its an m112 and not some forum thread I really believe its a m90.
Sigh.....
Well let me be the first to tell you that yourself and anyone else that is under the impression that the FRPP 2V blower is anything other than an M112 is WRONG.
The FRPP Supercharger (previously known as the SVO Supercharger) has always been an M112, since it's inception in the late 90's. Only when an article run by MM&FF a couple of years back, where it was "incorrectly" identified as an M90, did the confusion begin.
I've followed and researched this supercharger for months while I contemplated running it on my Cougar before finally deciding on the Allen kit I've currently got. And the only reason I didn't run it at the time was because Ford Hadn't finalized a kit for the PI heads yet.
You don't need to take my word for it, feel free to PM DropTopPony, or green_fow_six
as they’ve both got one on their cars. If their opinion won't suffice, you could try contacting Timb over at TCCOA, or ModularDepot as he's running one on his car as well.
Furthermore....and M112 uses a press fit pulley, as shown on this under hood picture of Timb's car an in the pulley image and link below.....
http://www.pulleyboys.com/fordsvtpf.html
The M90 uses a keyway system to affix the pulley, as show on this pulley image/link below.....
http://www.pulleyboys.com/allenengine.html
Another dead giveaway is the pulley diameter. Since the M112 moves so much more air per single revolution than the M90, the pulley size is noticeably larger by comparison. Standard pulley sizes for an M112 usually run within the 4.0"-to 3.5" range (depending on it's usage). Overdrive pulleys can be had as small as 2.74", but you're talking serious boost here, not for your average user and certainly not for use with a non-intercooled kit like the FRPP/SVO unit. The M90 uses a much smaller pulley to make boost, since it needs to turn much faster than the M112 to produce the same volume of air. Standard pulleys on the M90 run in the 3.2-3.0" range and can be run as small as 2". I'm personally running a 2.35" pulley on mine.....something that would be inconceivable for an M112.
Lastly, if all that doesn’t convince you, I’ve got a complete set of pictures and parts detailing the FRPP/SVO kit in a link provided by green_fow_six on another board…http://briefcase.yahoo.com/bc/bramr...w=l&.src=bc&.done=http://briefcase.yahoo.com/
Ford chose to cast isn't own one piece manifold for the FRPP/SVO kit but make no mistake about it, it is an M112. Notice the wider rib spacing and different over all design of the unit itself (pay particular attention to the area up front where the bosses cast into the case to bolt the nose drive on are external with the M112 and recessed with the M90 ). It also has a much longer and wider case to house the longer rotors (look closely, the rotor section of the FRPP case runs nearly the length of all four intake runners on the FRPP manifold, where the Allen kits M90 barely runs the length of three of the runners), as well as a completely different nose drive, in comparison to the M90.

Nose drive for the SVT Cobra/Lightning M112.....see any smiliarities between it and the FRPP/SVO Nose Drive?
This is an M90 Nose Drive.
M90S on the Allen Kit
M90 on the Saleen Speedlab Supercharger Kit
.....and in closing, i'll state that there (for the record) is your "definative answer"!

Yes they did Roush made a kit fot the 99 with pi heads. Unless you got that kit before 99Sigh.....
And the only reason I didn't run it at the time was because Ford Hadn't finalized a kit for the PI heads yet.
I'm not trying to be an ass about this, but I dont believe 50% of the crap on any forums. Who knows maybe ford made there own blower. Hey if 5.0 mag said it was a m90 and did not correct them selfs later doesnt that mean that they were right? Theres still no real proof from places like ford or eaton about this.
If your, right your. If i'm wrong what ever I dont care at this point. The svo blower sucks next to the other types of power adders out there TURBOS, KB, ProCharger, vortec, and No2. That svo doesnt even come close to anyone of these.
Anyways back to the main question. It would be great if some one made a kit for the 03-04 Cobra m112 blower for the 2v. There all over the place on ebay, craigslist ect... for very cheap prices. Also you would able to add an intercooler, bigger and better plenum/ throttle body, and also you would be able to port the damn thing. Doing the m112 this way would be a greater setup over the svo right??
By the looks of things, you may just get your wish yet.Stop clouding the issue with facts, I want to see a good pissing match.
Well....if you’ll read my post, I said “FORD” hadn't finalized a kit yet and the last time I checked, Roush wasn’t Ford. They're an aftermarket company that have joint ventures with the Ford and build parts and performance cars based on their platforms, much in the same respect that Saleen has done over the years. Roush has only recently climbed further into bed with Ford over the last couple of years with the retirement of John Coletti in late-2004 and the disbanded of SVT (Special Vehicle Team) in mid-2006. Oh....and I don’t consider paying $8,200 for a 2V Roush supercharger kit a very cost effective alternative, do you?
I didn’t call you an ass, but you certainly don’t seem to have issues with being unnecessarily argumentative. And I'm not telling you to believe 50% of the crap on the internet, I'm asking to you believe the facts and figures I've posted right here in front of your eyes. I can't make it any clearer to you....THE FRPP/SVO Positive Displacement Supercharger utilizes 112 cubic inches of displacement.....PERIOD!!! Not 90....not 111....not 113, but 112. It houses the EXACT Same rotors found in the M112 found on the SVT Lightning and SVT Cobra. The Manifold was built specifically as a one piece unit for the FRPP kit. Just as Mercedes, Jaguar and GM use product specific manifolds for their kits. It doesn't change their displacement or their internal components in the least though! If you’re really that concerned about it, and choose not to believe the facts and figures posted right in front of your eyes, why not call Ford Racing or Eaton Automotive directly and ask them.
....and as for a Mustang Magazines being perfect....you're not serious!?!
Of course not, why would you....I just shattered your initial theory all to hell. But I have to say, for someone who doesn’t car, you sure like to argue the point!
Thankfully, the original poster wasn't looking to make huge amounts of power with a blower. He wanted a nice entry level system that would put him in the 300-350rwhp range....and what do you know, that's about where the FRPP/SVO kit will put you.
And saying it "sucks next to the other types" couldn't be further from the truth. The Eaton Hybrid Roots blower is by far the most durable reliable unit on the market. Although there are others that are capable of making power, nothing can match it's durability. This is why it's the number one choice of OEM manufacturers worldwide.
Well, that wasn't the "main" question, but since I've already answered your previous question, you may feel free to change your wording around to make it look that way.
The only advantage a custom M112 kit utilizing a blower based from a Lightning/Cobra based M112 might have over the FRPP/SVO kit would be the addition of an inercooler. There's physically no way to adapt any sort of air/air or air/water cooler to the kit, like could be done with a "custom" set up. That being said, what a lot of users are doing is adding water/methanol injection to their existing FRPP/SVO kits and pulling better numbers out of them. The blowers themselves can also be ported, the same as a stand alone M112 and the runners and inlet can be ported and/or extrude honed to improve flow levels as well.
Would it be great if someone came out with a lower manifold kit to adapt the stand alone Eaton M112 from the Lightning/Cobra to a 2V manifold?....Certainly! But you also have to consider the need for a custom inlet, fuel rails, boost bypass configuration, EGR and IAC placement, as well as serpentine pulley and bracket system to make it work and this is all still assuming it’s able to be packaged to clear the stock hood line!
Perhaps you should spearhead a campaign to build them yourself. Maybe you'll get rich in the process?
Please correct me if I am wrong.
I have read the other threads about the FRRP and as of right now, the FRRP blower will fit a 99+ stang (the one made for 99+) but Ford never came out with their "install kit". However the blower will still work if you do a few minor things like (please add to list):
new injectors (what size?)
new fuel pump (what size, can KB's boost a pump work?)
new plugs (what kind)
tune
new alt bracket
redoing fuel rails
does the returnless fuel system have to be changed to a return style
other?
Thanks

Yay! It's like Christmas already.
You are partially correct. There is an instal kit for the blower as picutred in the photographs in the link http://briefcase.yahoo.com/bc/bramrs...ase.yahoo.com/ What they failed to initially was create one for the returnless fuel system I believe. This was easily remedied, but it can be a PITA for someone looking for a "complete" bolt on application. I do believe they're fully available now though.
The way to tell the difference between the M112 and M90 is the size/depth...the M90 isn't as deep as the M112.
My FRPP Supercharger is a M112...i've had it next to a M90 and its longer.
There is a company who makes a kit to fit the Cobra blower to a 2V but its expensive.

I love meat more than anything! I just have a spec
I've heard getting your hands on a new FRPP blower is fairly hard now. They are on backorder for several months IIRC...

THANKS FOR PUTTING IT THAT SIMPLE FOR ALL TO UNDER STAND.
I wasnt calling anyone out! I just wanted a simple answer thats it. Wow no more long ass post to make me look like an ass please!
thanks for all the info.
I wasn't trying to make you look like an ass, but you just didn't seem like you were getting it....so I broke it down in step, by step terms for all to understand. Don't take offence, I wasn't singling you out. All of my tech posts are always long winded and usually very thorough....ask anybody here who's ever had to read through one.THANKS FOR PUTTING IT THAT SIMPLE FOR ALL TO UNDER STAND.

QFT.
a lot can be learned by what you have to say
dont let it go to your head now mmmkkk?
wow...the fighting continues over this blowerPeople put down something they know nothing about. Why
How is your FRRP sc doing, any problems? What did you get from Sniper tuning, the complete DIY kit? Did you eventually get yours dyno tuned. I don't have any worries about installing the kit and fabing any parts or changing mechanical things, the thing that worries me is the tune. Before I go with the FRRP sc, I want to make sure I can get it tuned correctly, so please give some advice about your tune if you don't mind. Thanks
