On the 2-D sketch issue...

The vertical comparison may be "out of whack" on the scale unless the inlet is actually higher on the MP. I would think the top of the 'humps' in the Eaton and the top of the plateau in the MP would be on the same plane, as the bearing position is common. Maybe a profile shot would clear that one up.



The issue about the horzontal size look to be correct though. Look at the first photo - looking into the inlet throat. The screw lugs are outside of the plenum opening on the Eaton. On the MP, it appears that the screws go into the opening and the area below these screw holes is hollow.

My observations of the photos only - I'm not lucky enought to fondle and finger one in person

Herb, a front view would be good.

The first photo shows the top view of the two S/C side by side. (equal asspect ratio)

They both use the stock upper plenum.
The screw patten for the upper plenum is the same for both.
As I said the distance from the screw holes to the inlet openings appear to be the similar.
So the inlet openings must be similar as will.

Once past the inlet opening it's another story about 'Volume' and 'Flow direction'. ie. porting.

Some people spend 400 for a port job, some spend 1600 for a new case
and some spend 3000+ for a larger capacity S/C.
What do I know? I'm only 33 on the fast 'list' over on LNOC, so far.

What ever floats your boat.

I will E-mail Charles and maybe he can answer some of the question brought up here.

But what does he know he is only the engineer who designed the blower.

Peace,

I'll be listening and learning too.

 

Me too! Considering I just bought a KB

I E-mailed him if he is in town he will answer.

NoSuprise, hec 11.29 @ 120 mph is a good number what blower are you runing?



Suavy

 

And some people bought a MP and wish they didn't

 

I have a feeling there are going to be alot of stock block owners regretting their MP purchase. I've seen the dyno results, or lack of results.

 

JDM: "We picked up 87 horsepower and 90 ft-lbs torque at 16 pounds of boost. This increase was measured against the stock Eaton, also at 16 pounds of boost."

Has anyone been able to replicate this feat?

 

Those ARE some good numbers.

KB, but we lack the the 'Cecil' factor out here.

NoSurprise

 

................and the JDM dyno factor.

 

I can only report on what I picked up - 0... Going from a ported eaton to a MP with 2.7" upper on a stock block with 6lb yielded nothing. This included the MP idler, so belt slip was not an issue.



*EDIT*.. I'm not saying the MP won't perform, but not that these boost levels!

 

This started out as a good imformational post, but at the end it started to turn into a Magnum Powers and JDM bash fest.

Lets keep this and posts like this positive.

If I were to do it again I would choose a Magnum Powers over a Kennie Bell, mostlly for a reliability standpoint. While a MP will not give the power of a twin screw blower, it is a good alternative that you can bolt on and get a good increase in power and know it will be reliable.

 

And how far is Cecil from MICHIGAN?

 

Yes, but then again there is only one MP powered built block truck in the 10's and thats the Fridge (at 20lbs of boost) but there are several ported eatons knocking on the 10 second door at much lower boost.

From all that I have read, the MP is no better than a very good ported eaton, Hell it even uses the eaton rotor packs.

Steig ported my intake for my GenI and the workmanship is incredible and I have seen firsthand their porting job on an Eaton and if I were to own a GenII, I would take a steig ported Eaton over a MP anyday. As usual, JDM hyped it and it didnt live up to the hype.
