Maybe I missed it somewhere; but, does anyone know what the displacement on the MP blower will be?

 

Ummm... Suavy will know, he has one.
If he doesn't reply, try PM'ing him (here or NLOC.net)

PM him or call JDM

 

Odin, I tried to e-mail you but your e-mail and PM is blocked.


Suavy

 

I appreciate the effort. I didn't know it was such a big secret. I'll just wait til it's out for everyone to know. I was just curious is all.

Thanks,
Roger

 

As I have stated before I am just a test mule for MP Jim is the Main distributor for them.

I was asked by MP not to give out any info and if anyone needed any info to direct them to JDM.

Sorry Amigo.

Suavy

 

That's cool. I wasn't directing the question to you, but to anyone who might know. JDM is a supporting vendor here and this is a question that I can't imagine would be a problem for them to answer publicly. It's info that others would be interested in also. l-menace put the onus on you for the answer, not me. I understand your position and respect it. Thanks again.

 

Thats cool Odin, I can tell you this I like the heck out of mine. I don't know how it compares to the production version. I know mine has made 24 lb. of boost at 3300 rpm.

Peace, suavy

 

Well....since the MP uses stock Eaton rotor packs, my guess is the MP is right at 112 cu. in. displacement. Is that what you wanted to know ?

Since it uses the M112 rotors then it has to displace that much volume. Dale

 

Sauvy, what kind of pulley setup did you use to make 24 psi? I'm just curious how the Magnum Powers 112 compares to the Works 112. I ran 18 psi on my WP112, although I never tried taking it higher.

 

Bad as L

I'm not sure but I don't think I ever heard of a stock Eaton putting out as much boost as I got out of the MP.
I am finishing my engine by this weekend (Again) and hope to take it to JDM for my race tune we could not tune it last time cuz my stock fuel system wouldn't keep up. We shut it down at 3300 rpm. do to a dangerous lean condition. We did however make 24 lb of boost at that RPM. I am set up to make 26 lb. of boost now.
I put the full 26 lb to it on Laborday weekend and lifted my heads and blew both gaskets.
People said, "that thing sounded like a friggen jet taking off!"
I hear JDM has a truck that ran the MP blower that has now ran 10's.

Not necessarily. The stock 112 is rumored to displace somewhere around 90 ci due to the top entry. I am curious as to how much of an improvement has been made. By shortening the snout and moving the rotors forward, by increasing the case size somewhat, a true 112 could be possible. Even with a top entry design. How close is it to a true 112 ci is what I'm trying to get at. I'm sure there are limitations as to how much longer the case can be made; so, that could limit displacement improvement. I could be way off base here on what they've done to the blower; but, that is what makes sense to me.

 

Odin
I beleive that the volume is calculated on one full revolution of the rotors. It will displace 112 cu in. You could cut the whole top out of an eaton case and it would still make boost, just not very efficiently. Just because the rotors are exposed does not mean the blower wont "displace" X amount of air.
The stock L eaton has a small portion of the rotors exposed to the inlet. That doesn't make it easy on incoming air, but I'm pretty sure it doesn't make it a 90 cu in blower.

Sauvy
Make no mistake bud.....I believe you when you say you made 26lbs of boost and no I don't think a stock eaton would do that.
The changes that MP has made to the case are subtle but very meaningful. Besides you were spinning the blower with an 11.5" lower and I believe a 2.7" upper, is this correct ?? And the high boost was recorded at less than 4000 rpm before the engine had a fit and shut off.......if I have my facts straight here, then yes I believe you.

When I ran a ported eaton last year, I ran a 9" lower and a 2.8" upper and it made 15 lbs right off and then would fall back to 14lbs.
