Project FORDenstein M90 on a 3.0

[jamesdem1123]

So first off this is an ongoing project and is going to take a long time so updates will be far between....

I'm putting an Eaton m90 off a tbird supercoupe on my 3.0 ffv. My goal for now is roughly 235hp ish. A little more than a 4.0 swap which is why I'm doing this instead the swap.

Some of the components I will be using will include: Eaton m90, supercoupe intake tube with bypass, throttlebody, tps and IAC, maf housing and intake from an 09 mustang, wideband a/f meter, upgraded fuel pump, sniper tuning or megasquirt (havent decided), and probably a hundred other bits and pieces. I probably won't upgrade the injectors or fuel rails as its a flex fuel vehicle so theyre already about 30% larger than they need to be and I will be raising the fuel pressure to get the flow required.

since here's somewhat of a "mock up" to see what i have to do.

top view of blower and intake somewhat in place.

front

right side

left side, the stock intake box will be cut and used to mount the battery and above that will be the reservoir for an air/water intercooler.

for the pulleys i will mount another idler to the alternator so I can get as much belt wrap as possible on the supercharger.

coils will be moved to the firewall and also i will make brackets to attach the super charger directly to the header studs for lateral support.

the stock battery mount will be removed to clearance the mustang intake box/custom cold air intake

stock throttle body compared to the

supercoupe tb

upper intake manifold removed

very basic drawing, there will need to be a spacer because the bypass is lower than the mount as usually this supercharger is mounted with the outlet up and a box on top to collect the air. I'm guessing the total height of supercharger and intake manifold to be about 16 inches so it might just pop through the hood

Nice start. Please continue to update us here as there have been many questions asked about doing a install like this.

okkk this is sickkkkkk, but why goo through soo much with the 3.0 if it seems like you want some power?! (although 235whp was more than i had with the 4.0 sohc manual tranny, m90 6psi,stock MAF, stock injectors, stock pump, JBA headers, straight pipe arfter last cat....that all got my 200whp...)soooo ahaha i guess this might be the way to go! gonna run the small 2.8 pulley? water metth as well??

if you need the MAF, i have a mustang GT 80mm for sale

Maybe this will give you some ideas... and that book you see from Corky Bell? Read that too.

I love the sound of a blower.

 

[jamesdem1123]

you can't see it in any of the pictures but the maf housing is part of the intake, its close to the fenderwell.
We're you using an intercooler or no? 200hp seems reallly low unless you were at a high altitude, except PD blowers are sensitive to intake and outlet restrictions so that could have limited you too. My next step is to draw the manifold up in cad. fun stuff.

Not my car.

lol I've seen that subby before, the supercharger kinda reminds me of a prairie dog poking its head out. I think its kool that he went with a supercharger instead of the readily available turbocharger, somewhat unique.

If I were going to put an Eaton blower on a 3.0 I wouldn't use an M90
and I've already got TWO M90's both off of 3.8SC engines...

what I'd use is the M62 Eaton off of a GM3.8

It's smaller, a more appropriate size to the engine, and will make
enough "Stuff" to pump some muscle into that 3.0.

My concern with an M90 would be worrying about overboosting it
and bending those wimpy connecting rodsinside a 3.0

With a larger pulley to cut down boost the M90 will work just fine on the 3.0L, it works great for anupaum on his 2.3L... The m62 off the GM is a PAIN in the butt to work with also. That it what the imprezza is using in that link and you see the odd setup the intake and exhaust ports use on it. The M90 off the supercoupe is a beautiful setup because of the intake elbow and the simple rectangle output port of it. With the M90 just slowed down to keep the boost low it will also keep the heat down some. If you build the internals of the 3.0 it would be a blast to run that thing at 12 PSI though.

 

[jamesdem1123]

lol if i go as far as forged internals i would probably pulley it for 18 pounds and go for 400 hp ish.... the intercooler setup i will be using will be good for 400 hp easy. im looking for maybe 6 pounds of boost and 235hp on a conservative tune.

 

[jamesdem1123]

played around on autocad a little bit. i havent done any 3d drawing in a longgggg time. from the pics you can kinda see where im going with it. the supercharger will mount on top of a 2 inch spacer on a 1/4 inch plate which will sit on the top of whats shown. it will be made up of three pieces: the lower supercharger manifold, intercooler core, and supercharger mount. it will be held together by bolts mounted externally through aluminum tubing.

Very Nice, I cant wait to see the end product...

Thanx,

are you going to machine your intake yourself or pay to have it done?

 

[lifted4.0]

has anyone in the history of m90 supercharger ever put more than like 15 pounds through it..i dont know if an intercooler is gonna help in that case
