Eaton M62 electronic clutch as used on a merc compressor????
Anyone know anything about the clutch and how it operates?
Is it entirely self contained and just needs a +VE signal to engage or something like that, or is there a lot more to it than that?

Been reading a lot on twincharged cars in Oz, they quite popular now, and if you thinking of disengaging or bypassing the charger once the turbo is on song, dont bother.
From what they have found, its pointless and it seems contrary to everyones belief, the Delta S4 didnt even do that, its just a myth like wastegate chatter and dumpvalves that do things
The supercharger bypass on S4s and so on are for at idle and v.low speed running it seems, though a clutch will do a similar job.

It needs voltage
The ecu sends the cluch a signal once the tps sensor reaches a certain voltage
There is another signal the ecu needs but im not sure where it gets it from
just found out its a load singal...........the blitz compressors work in the same maner.
But to be honest i would just get the ecu reflashed and machine a solid pulley
but thats just me

Not interested for compound chargnig, purely for superchargin and being able to disengage the charger for economy reasons on long runs.
(saps about 15% fuel economy running it!)
cheers for the input lads

does that matter, so long as you can do it on the move....
I'd say the torque limit of the clutch is the important bit.... assuming you want to run higher boost than std!

10psi would be more than enough for what im after.
Just want to drag a 160-170bhp 100K mile 325 engine up to about 230bhp or so (charger consumes 25 or so though, so need 255 at the crank to make 230@ fly)

Seriously considering fitting a cheap M45 running big(ish) boost to the SX once i blow the T25 up, should be good for over 220bhp and the instant responce i need...

Im busy, translate that into possible power pls mate
BTW 14k it goes to on there, but i know for a fact some chipped Mini CooperS's spin the chargers to a bit over 17k!

Then you mutliply that by about 10.5 or so like on a turbo, then you need to subtract the losses from the charger, as a general rule the losses on this sort of charger are about 10%, but its no linear obvioulsy
Basically, the M45 is good for about 220bhp or so really.

At 120quid a pop on ebay il take my chances with 17,000rpm
Jus mount it in a way that its easily removable when replacing them constantly
Even 220 will do, but seen more quoted many a time on PooperS's, which will be a billy bonus, std inj's are good for 250bhp or so on 13s...

its a displacement charger dont forget!
turn it too fast, and it just chops the air up and doesnt flow anymore, in fact it flows less, its not like a turbo or a centrigufal charger

Steve, by the way that one i posted up will flow 440 CFM of air versus the M45 with 320
So thats an increase of about a third, so will do 300bhp as easily as the M45 does 220bhp
you can get a recon one from the states with clutch for 500 quid.
so probably cheaper than you realised!

I can trash 4 ebay ones for price of one of them tho
And if its under 250bhp i can stick with standard inj and AFM, and i reckon a stage2 chip should be able to take care of the fueling.
Remember, this is my S13 drift scrapper, money is at a premium

No map sensor on your version of motronic i dont think mate.
Car im doing it to wont be able to see boost if done on standard management.
im going to have a go at a low boost install first with an ERL MF2, if that doesnt work well enough or if i want high boost, i will use a wolf V4 ecu instead.
If i got over 200bhp instead of the 170 or whatever it is now it would be proof of concept enough to make it worthwhile doing
I have both lieing around brand new never used anyway
Its a 325 12v engine its for.
But longer term plan with this car is a 325/328 24v motor with the same charger and around 280-300bhp

silly question, but a supercharged engine should not need a map sensor, as it is a constant speed unit?? ie 2000RPM = 3psi, 4000rpm = 5psi, 6000rpm= 7psi ,etc etc, A turbo has a map sensor as from what I can see it has infinite load positions vs turbo speed/boost, a supercharger is always at a set RPM relative to the engine RPM due to the drive belt? I know its probably not that simple, just me thinking out loud, and I have spoken to vaan aitken efore about 'charging a mk5 RS 2K, and they reconed they could just piggy back the origional ECU with a separate map for the charger ??

Also you would need an ecu that could switch between "charger on" and "charger off" totally different maps
far easier to just use a map sensor really IMHO

In fact technically airflow vs rpm with throttle as an adjustment should work on ANY engine, even turbos!
Thats how pulsars are for example
