The Eaton corp. web site!
I cant make anthing out of the eaton coprt site! Eaton is a multicompany that sels anything. The only thing IU can fint for the eaton is the newest generation but there's not any real spesification there.

I was hoping a more detaled then the one Bruce gave me but, that will do.
Thanks Bruce :)

why not just upgrade the eaton m62 to the M90.
Because there is not enough place,and even if you could install M90 into the M111,you wouldnt see any gains comparing to double pulleyed M62! So why bother?

Snogard, your knowledge of this power plant appears to be extensive. Mine is limited to the two weeks of ownership. I joined this forum today, so if you claim there in not enough clearance for the slightly larger housing of the M90 (3/10" W - 0" L _ .52" H ) I believe you. But I find it hard to believe you wouldn't see any gains compared to the lower output M62 driven equally. I do have more than limited knowledge concerning forced induction on American autos. I know you can explain why more air/fuel would be a waste. There also seems to be some contradiction on the pulleys. Didn't I read a post that claimed double pulleys actually created a loss of performance on the dyno? Speed is money! How fast do you want to go?

You read wrong about loss of performance when using double pulleys. First study M111 and its demands and then read again this forum (and topic we are talk about double pulleying) and then take a look at dyno graph of double pulleyed PreFl M111 i posted few days ago. Not one single pulleyed M111 managed to produce that much power then double pulleyed M111 PreFl. And even without graph it is obviously that my car could not manage to get from 0-100 km/h in 5,9 seconds and loose grip in 3rd gear on dry road if double pulleys (and all other stuff i made on engine) wouldnt work.

Yes, stock M90 have better flowing characteristics than stock M62, but only SLIGHTLY bettter (if ANY at all) comparing to double pulleyed M62. On top of that remeber that M90 it is much greater parasit in terms of power it demands from the engine to drive it compared to double pulleyed M62.
Second thing is that you can not endlessly enlarge volume of blown air, because engine will start to ping and starve of fuel! Double pulleyed M62 is getting JUST A WRIGHT ammount of air to the engine with not too much parasitic loses in terms of PS and TQ; any more blown air end you have to make drastic changes to engine to make it not ping and starve from fuel.

3rd thing: M90 is A LOT larger (mostly longer) casing then M62 from PreFl M111. You would have to change A LOT in the engine place if you wont to put M90 in. On top of that-M90 does not have clutch and at least for me that is serious minus.

4th thing; If you are not beleaving me, Linh has told the same in other thread; Let me citat his words for you: "Kleemann went throught with R&D but scraped it in the end."

So you are THE only man in the world that i know (and i know A LOT of M111 owners and other mechanical specialist, tuners and other professionals) who claim that M90 should be put into the M111. Think about that before you write again in this topic.

Lastly: Dont know about your knolidge, but this are facts that i am telling you. And my 5 cents at the end: American cars are NOT european cars.


Ask yourself why no one (not even the greatest enthusiast like me who dont care for nothing else, just HP gains) EVER used M90 on M111.

Beleave me, you wont rediscover a wheel here...People have already think of that, been there, done that and discover that it is not worth it.

If you have such a desire to put higher output SC into the M111 (even if you know that it is not worth it), then i suggest you to put Eaton TVS blower. Only then you could ;MAYBE see spome gains in terms of less parasitic loses with the same output (not because of greater output itself). But TVS series is still not available, so at the end you still stuck with double pulleyed M62.

P.S. It seems to me that since you join our forum, you are deliberatly looking and exploring my posts and kontradikt everything i wrote... I have advice for you;
Rather try to correct posts that deserve that!

Snogard, I never said a m90 should be substituted for the m62, I just asked if the higher output would make a significant gain. The eaton Third Generation m90 is zero longer than the m62. Before you attack me check your facts. I am not seeking to invalidate your posts, so ease up. we are all here to have fun and make improvements.

You didnt ask for opinion, you said that you have hard time to believe me that M90 will bring no gain. Let me citate your words: "But I find it hard to believe you wouldn't see any gains compared to the lower output M62 driven equally" End of citat.

And that statement is different then question. So do not turn your words when you see that you loose arguments.

M90 is (in terms of free space under 230k hood) A LOT bigger than M62. And until wright NOW you never before mention that you have in mind 3rd (and not 2nd) generation of M90, so before YOU attack ME, do your own homework and next time write down specificaly that you dont have in mind 2nd generation of M90 like we all others think (which is from the time of M62 which is in the M111).

Btw. i own a car with M90 so beleave me i know a lenghth of each generation of M90.

Thanks for clearing up the confusion I created by not specifying a third generation my bad. Now that we are on the same page I appreciate the knowledge that dual pulley's make a better upgrade than the compressor swap. (I still want to believe the M90 gen 3 would make a big difference. has anyone researched that?) My goal is to create 275-300 HP from this engine. It sounds as if you have come close to those figures with mostly external mods congratulations, I have learned a lot in a short time on this forum

BTW I own a car with a GMC671 roots type blower and would never try to put in in a m111. That might be cute on the slk with a snorkel hood scoop!
