i'm looking for an eaton m45 second hand? can anybody help?

Now that's good timing.....

I was just about to put a post on selling my, hardly used, M45 blower. It's currently in and working merily on my bug's T4 motor (see pic). There's a genuine reason for the sale too, the M45 is designed for anything under 2.2litres (my engine is a 2.4litre) so I can't get anything over 6psi boost out of it cos the engine is asking for more air than the M45 can give out, that's why I'm just about to buy an M62, which is designed to be used on engines up to 3.5litres.

So as long as your motor isn't above 2.2litres the M45 is ideal for up to 12psi.

Give me a call if you're serious on 0780 3513210 in the evening.

Moggy - what power are you getting from your engine, and at what engine speed? What drive ratio are you using for the blower?

The M45 is good for 320cfm inlet airflow at 14000 rpm blower speed. Can you increase the drive ratio to the blower? If you match the max engine speed (5600rpm?)to the max blower speed (A drive ratio of 2.5), then you might be OK to keep using the M45. It depends on whether you like to rev your motor, or prefer to make the most of all that low down grunt?

It's just a thought. You might have already done this.

Moggy, I like your pulley and belt system. Where did you get the crank, fan and idler pulleys?

Moog

Yeah, tried all that mate. It's got a ratio of about 2.3, I don't rev it over 6000rpm (=13800rpm blower) so it's at it's max now. If you look at Magnusons site you'll see they advertise the 45's for 1-2litre cars and the 62's up to 3litres. The guy at supercharger UK who recommended I use the 45 is a dick, and cost me a lot of money and wasted time ( not to mention wasting alot of John Mahers time trying to figure out why we couldn't get anymore than 6psi out of it). I've spoken to the guys at Magnuson products directly and they said there's no way I should be using an M45 on that engine if I want to see higher than 6-7psi.

I made them all myself.

I'd guessed you were close to the limit for the M45, but i wasn't sure how close. I have an M45, and was hoping to get close to 200bhp with it - looks like i'll fall just short of that target.

Cheers

Moog.

it seem's like i'll have to go for the M62 because I'm looking for 250 - 270 bhp!

Moog,
is 320cfm from the M45 the advertised flow?

Moggy, ever sell your M45?
I just picked up a M62 (?) from a Ford T-Bird SuperCoupe for a extra 1.8 that I have.
I was going to run it thru a set of dual Weber 40's, but I'm not too sure if that is a wise thing to do after talking with John M.

These units such as the M62 series sell for about $300 US dollars normally (used). I picked mine for $100 and I just couldn't pass that up. At that price I could use it as a meat grinder and be happy

'57 - the M45 pumps ~320cfm @14000rpm blower speed. Go to http://www.eaton.com/supercharger/M45.html for the specs.

Thanks Moog, that was helpfull. If I
could trouble you further; I calculate your
motor 144.4ci, at 6000 (four stroke thus
x 3000) requires 250.8 cfm....where did I
go wrong? obviously it needs more than this. Thanks , Glenn.

just wondering if any one can calculate the flow in CFM for moggy ' s engine...? ...
Its 144.4 CI revving at 6000 rpm for the calculation.
Id like to see where I miss-calculated.

Has any one heard of a J. Mueller who moved from Aust to Canada (I think).He's Really into blowers & turbos.

Moggy:

That is a really hot setup. I too am interested in the performance figures for this setup, and your future setup. I'm very impressed with the work that you did to fabricate the setup, and was wondering if you had any pictures of the air routing system. From what I understand the outlet is on the bottom of the supercharger, what route did you use to redirect the air to the top of the carbs? What sort of mods did you have done to the carbs? how much did it cost?

Thanks!

Here's some pics to help u c how I rooted the air from the underside of the blower to the carbs.

1st pics the underside of the blower.

other ones are showing u how I routed it.

I've got loads of other pics of the kit from loads of other angles if u want to see them, including quite a few of the engine in the car and the car itself.
