Not that I really care, but it's not all that efficient to type like that either. It makes it impossible for others to read, and the whole point of posting is so that other people can read what you say. . . but I'm not trying to make fun of you. . . just pointing it out in case you never thought about it. Besides, I think it is frowned upon on most forums.

wasnt ThAt TypIng cool back in like the early 90's?

it quickly died because it is completely stupid and very annoying, no need to candy coat the painfully obvious.

not knocking the person, just that form of typing!

To those with constructive input, thanks

I honestly don't really care if it works or not. I would obviously like it too, however I am more doing it simply to say I could and did. If it works, we have a cheap way to make good power, if not, I wasted money but had a good experience.

Hopefully I should have some more progress later this week/weekend. It will probably take at least a month to finish this as I have school, etc.

LOL...I was thinking that too. Our first negative post! And I didn't think it would take this long.

Well, we'll just have to see, I think it's big too and he explained why the m62 and not the m45, so I am NOT going to question his knowledge on it because I don't know enough about it to say it won't work.

Proof?

What basis do you have to say it's too big or too small?

Give me some numbers, some technical specs, anything.. but to simply say it's too big on your own conclusion is pretty weak.

Bring some information, not just opinion please. Don't get me wrong, your more than welcome to question it.. but if you know something we don't, by all means share.

show me you'r proof as to how it isn't too large. look at blitz or greddy. much smaller. and keep saying it's barely larger that's bull. the blitz's i've seen were minuscule compared to that. i have no proof. is that what u want me to say? fine.

whatever makes u happy.

Here, this is for you.

I used photoshop to remove the excess inlet section and moved it up to the rotors just like the greedy. I also removed the extra mounting feet that is required for general motors vehicles.

**Without knowing the exact model used by greedy I cannot make the direct comparisons** -edited


This is the GREEDY blower:




This is the M62 from Eaton without the extra inlet tube (right up to the rotors like the greedy) and without the extra feet (used for mounting them to GM engines. It's no larger PHYSICALLY other than the extra crap on it..



I'll dig up the tech specs for ya later. I have to anyway, just haven't gotten around to it. If they indeed use the M45, great. I simply have to spin the M62 slower to achieve the same goal. Even though the Mp112 was designed for engines larger than the 3.8L 3800, they still work just fine on them. The m62 was 'designed' for 2.0L up.. it will be just fine on a 1.5L. Anyway, it's all 'speculation' but at least I'm trying..

Tell ya what, you don't have to buy it! ;)

Just don't know why your such a sourpuss about this? WHatever floats your boat!

i'm not a "sourpuss"

don't you think theres a reason they suggest it for a certain engine size? optimal conditions.

I just went to eaton's site and looked at the temperature charts they have listed.

The M62 can flow more air per RPM (obviously) than an M45. However...

To achieve the same airflow the M62 can spin 2,000RPM slower than the M45. As such, the output (m62) temperature at 5psi is ~5-10 degrees F lower than it would be at the same RPM of the M45. Because we are spinning the M62 slower, it also requires less HP to drive it than it normally would if we were staying at the same RPM.

So, to spin an M45 at 10,000 RPM @ 5psi requires 9 HP. This is at 220CFM.

To spin an M62 at 8,000RPM @ 5psi requires, uh oh, 9HP.
This is also at 220CFM.

I am sure there is a small (1-2HP) difference simply because the rotors are bigger. The volumetric efficiency is also 5% less for the M62@8,000rpm than is the M45@10,000rpm.

For all practical purposes.. this blower is $200-300 and within , I'll even say 10%, of the M45 class at equal flow rates. I'll take that loss but I am betting it is less than that.

By the way Hotbox, I'm not trying to get on your case. Of course there is a recommended range, but as you can see, it can still work by running the numbers Eaton Provides.

And again, Eaton says the MP112 is for 4.8-6L engines yet we have plenty of 3.8L engines running low 11's and high 10's in the quarter using the bigger blower. Slower RPM, usually more efficient.

What would the world be without doubt? I welcome it, but I urge you to provide some real life data as to your claims instead of "It is to big", deal?



Anyway..

Here are the charts for the M45:



Here is the M62
