I was looking On TGO and
saw this custon M90 super charger set up on a tpi.
Its cutom, but will it work?????
What do you think the boost would be?

check it out. see below

Its my plan....

Really you need 2 of them to create any real power increase. Also, it will take a LOT of custom fabrication, and computer work.

How about going up one size on the blower?
M112, or somothing like that?

an M112 by itself would support a good amount of HP. That is the supercharger that is on the Ford Lightenings, GT, and 05 Cobra's.

The problem with the M112, is fitment. IT is several inches longer than the M90, which makes fitting it, and plumbing it in a bit more difficult.

So what do you estamate the power added with one m90????

do you know anyone or read anything about a mod like this?
Iam very interested.

I wouldn't mind twin m90's sicking out of the hood a little on both sides.

1 M90 pushes 90ci of Air per revolution, at about 70% effeciancy.

The redline on them, allows you to run about a 2:1 ratio to the engine RPMs.

So in each engine revolution you get about 180ci of air.

On a 350ci engine, each revolution, your motor displaces about 175ci, giving yourself 180ci of air, doesn't really get you anywhere. Not persay any possitive boost ratio.

(now, this is over simplified, the VE of the engine means it really only uses about 150ci of air, giving you some positive pressure from an M90, but it is not much. Couple that with the 70% effeciancy of the blower, you really end up with a very small actualy pressure ratio, after all of the thermo dynamics are done (the effectiancy of the blower, determins how much it heats the air, as the air gets hotter, even though you have displaces 180ci, the actualy ammount of air, comared to the ambient air that you would get NA, is even smaller)).

Gereraly speaking, from the ford SC guys, and the GTP guys online, an M90 maxes out around 300hp.

How much with the twin setup you are doing?"??

Dewey316 · Posted: Fri Apr 14, 2006 8:52 am Post subject:

with the twins, you can get about a 1.6 pressure ratio or so, which is pretty good. All in all 2 M90's should support over 500hp pretty easily.

I'm going to be running them on a 327, So my requirements change just a bit. I am shooting for about a 2:1 pressure ratio, which means for ever HP i make NA, i'll make twice that supercharged.

It is not an easy project though. Everything you need will have to be custom made.

Do you mind me asking about your project?
327? tpi? tbi? carb?
some specific stuff?

computer????
Year?

any one else do this?
thanks
scott

My project hasn't started yet. So many things are up in the air. All that I know right now, is it will be a 327, with 2 M90's.

Is there a way to change the oil?

The M112 works great on 5.7L I know as the ls6 in the V has one bolted on it. Makes about 8.5 lbs after the pulley swap.

they tend to generate a good bit of heat though.

I am beginning to think I will change the oil in it soon. Something else to add to the list. Evil or Very Mad

Did anyone notice that this thread was resurrected from '06?!?! Laughing
