well, you can fabricate anything, but to use the m90 would be a lot more work than its worth

the m90 is decent on the supercoupes, but they run out of steam up high, and dont make much power up there at all

if you sit and think about it, i dont know your fabrication skills, but if you were to buy the blower, in the inlet tubes, and all that , because youll ne the s for it, you might be in the hole, say 300 bucks, then some fabricators/machinests want 70 bucks an hour, the the cost of supplies, and then you may have to buy other parts for the project...it might even break even with buying a used kit, and modifying it to fit

Knowing him, my guess is that he's gonna recommend a turbo. :p

If you really wanna do an Eaton style blower look for an Eaton M112.  Those are the blowers on the Ford Lightnings and 03-04 Cobras.  They pop up on EBay all the tim and to pay $150 for a good unit is not uncommon.

well, what i would do, is check out whats already on the marketand start seeing how things are designed, and seeing if you could replicate the designs, and things like that

mouting an M90 would require a lot of fabricating, youd need to make a custom inlet, custom discharge tube, custom mounting bracket, youll possibly have to find a way to make a crank pulley, using the SC's and your own, or something like a lightnings, who knows, then youll need to worry about how much boost youd get with the pulleys, because you never know untill you wind it up, then you have to worry about space constraints, you may loose your a/c and smog JUST to make room for the blower

go over to turbomustangs.com, they have some VERY knowledgable people on both superchargers and turbos, they generally sway towards turbos, but there are some very fast supercharged guys there

keeping in mind i can fab something up to go on my 5.0 non fuel injected motor... how much boost does this have? can it be adjusted? thanks all for the info but could use alittle more, i cant seem to find much info on how to do this... and to answer someones question just to use a 3.8... WHY...more power in the 5.0 and with the extra boost it should bring me up to 330 hp .. atleast right guys. lol

well...boost is different per car, one the 3.8L, it makes 15psi or so, but on your 3.8L, it might make more, or might make less, its unknown untill you put it on, and take it WOT

as for adjusting it, the only thing you can do is change the pulleys, which is just a PITA after a while

as for your turbos...who told you they wouldnt do anything for your car?

fordmuscle.com has an archive on the carb'd super charged engine. Maybe that was a turbo but anyway,, give them money to subscribe to thier entire board,,15bux last year from me and it was worth it.

dont dare turn down one of these blowers if you get your hands on one.

as for the rest of your question,, there are many many ways to explain it.  I highly suggest you read up on how a blower works,, the vac that ties into the charger itself,, the rpms which it happens and all that good stuff.  Its really a long novel to explain all the 5 w's of bolt on blowers without having read up on the basics first.  yes they can be adjusted, modified, tweeked ect ect as well as a turbo.
