Eaton M24 Supercharger

Has anyone ever seen a compressor map for an Eaton M24 Supercharger?

24???
do you mean 42?

No I mean M24.

Apparently Ford Brazil used them on a supercharged 1.0 Fiesta and I think they may be used on the Twincharger Golfs.

Axel i think you are right they where used on the golfs. I think i remember seeing the compressor map on the eaton website. I was going to ask suitability of the m24 last night actually but i decided to try and do some research first.

I've seen an m24 up for sale at the moment.
A small unit as well, must be an intresting unit for those looking to charge a 1000cc!

From what i have managed to find on this supercharger it is designed to be used on engine between 800 - 1000 cc but i havent found much else other than that

The only info I have is as follows:

Swept volume - 24 cu ins, 400 cc
Max speed - 15000 rpm

So at a 2:1 drive ratio it will provide around 9psi of boost on a 998.

Good for 100hp with a decent intercooler.

Now just need to convince Sturgeo that he needs one on his car. He can then pay for the one I've just bought on ebay!

3 years later but maybe it helps

Kompressor:

Modell: EATON M24 Supercharger

weight: 4,8 kg

cc per revolution: 0,390 Liter

max. pressure ratio: 2,0 Bar

Max. RPM 17.000 (18.000)

pumps at highest rpm at 1,8 Bar so about 13psi: 380 m³ / h

Thanks.

Unfortuntaley gave up on that project.

Interesting though Paul. for 110 bhp you're off the top of the map (2.1 PR 300m^3/hr

Yes, superchargers really are crap at anything more than 5-10psi boost.

I can't understand why anyone would want to use one, but then not a lot of people understand the map.

That's a bit of a generalisation Paul. Might be farer to say Eaten M24s and M45s are not very efficient in our application.

Wow, a minute and a half to get a reaction. glad to see you guys are awake

The M24 is for sale if anyone wants to prove me wrong.

Am I right in thinking that you were going to have a go at a twin charger setup with this charger at some point Paul?

If something is worth doing, it's worth doing half of.

Totally agree paul, also look at the kW required to drive it, that's all power gone from the engine.

Personally I don't rate the eaten chargers, but that's only based on my readings and other peoples experiences - nothing personal to back this up.

If I ever finish my car, I plan to try and make an efficient blow through supercharged 'a series' engine. There has to be a descent charger out there somewhere...

Thanks for that efficiency map. I couldn't find one anywhere. I have one from a Golf tsi which was to be used on a Reliant 850, now an imp 875 which driven at 1.98 x engine speeds looks like it will be quite efficient (for an eaton!)

Anyone fancy explaining that map up there for someone that has absolutely no idea what hes looking at???

This makes good reading http://www.turbobygarrett.com/turbobygarre...bo_tech103.html

that map contains lots of info, but the most intersting is the green squiggly lines. these are the efficiency curves (the higher the efficiency the less heat is put into the charge).

Y axis is boost (in pressure ratio) x axis is flow.

From the link above you can calculate what flow rate and boost you need to make your desired power. then plot this onto the map to see what efficiency the compressor will be running.

The other lines show power consumption and rotor speed.

I've also found this which may be of use?
