Or get sent an email when he recieves a PM.

I can't find any evidence of why he left? Sad to see, he always he good input.

Yeah, I'm trying to get a hold of him, but no email anywhere.

I've got him on msn, but haven't seen him on in ages... He must have changed email aswell.. oh well bye nathan! thanks for all your help!

Ok, I have a very important question.

I was planning on using a Mercedes Benz Eaton M62 supercharger (roots type) for my build. But, since I like to reasearch things to death, I made a startling discovery.

These chargers are designed for vehicles with fuel injection, not a carb. With fuel injection there is only air being pulled through the charger, not fuel. Which could be a problem.

So I emailed Eaton and asked them about this. So I asked if it was ok to run a fuel/air mixture through the charger and they said that it is NOT OK. Since the seals and other items in the charger were not designed to have mixed air runnign through them. Eaton said it can be done, but that the charger will not last long, and bad things could happen

The Toyota charger is similar to the eaton charger.

Do any of you who own them have anything to say about this? I'd hate to have a charger burn up because the seals go bad and bearings get shot. The last thing I want is chunks of busted up charger pieces getting tossed around in my engine.

Mini Mania's kit runs an Autorotor/Lysholm charger, and it has been proven, for Mini applications as well as MGB's, Sprit's ect.

You could use the Eaton charger as a blow through setup couldn't you wouldn't be as simple or easy, as the carby would have to be able to deal with being pressurised which effects the jetting and makes it difficult.

Does the Metro turbo carby (whatever it's called) work for supercharged applications maybe that is the go?

Fuzzy- Good point.

But I still think that the toyota charger will have the same problems. I hope I can be told otherwise. It will make things a lot easier for me!

Or I could just switch to EFI. Looks like I have more research.

Here's the M62- Also has an electric clutch, so you can turn it on and off (worthless without EFI though). This is for 2.4 liters and up, and they are smaller than the SC 12 I think (11.5x7x5 inches)

If you do EFI there are a whole host of problems if you go port injection on the 5 port head read:
http://www.starchak.ca/ for a run down of the difficulties

Marcel is a member on Ausmini member name: chichm he has since decided to use the Elder 8 port head for his EFI project; look here: http://www.ausmini.com/forums/viewtopic.php?t=10654&highlight=marcel+efi+5+port

Yup! I have read all of that already, and I hate the idea of EFI. I bought a Mini cause it's simple, I don't want to have to add more electronics.

Yes. I've heard some bad things about using a suck through arrangment with the SC12, SC14.
The Gemini guys won't touch them anymore using a suck through set up.

What have you heard?

TK- Do you have any links to the Gemini discussions about the SC12 set-up? I'd liek to read up on it.

Im still going ahead with mine and from what 92 has said it seems he never had any problems with his until he ran the boost levels higher than what the charger is capable of handling. Im gunna be running the standard 5-7 psi for quite a while , and hopefully the charger will last! Also who cares what gemini owners think, in my opinion theyre one of the worst cars to come out of this country, im sure that'll offend some people BUT THIS IS A MINI forum and im entitled to my own opinion,

If the Rotors are Teflon coated (like the Opcon Autorotor - Aka - Mercedes one) then Suck through is probably a very, very stupid idea (teflon = Fuel soluable = sheets of black sticky crap in your engine. . . . )

Old School blowers donw have this stuff (I'm talking Wade, or GM Diesel Blowers) but they also cant run the kids of boost the modern ones can...

Maximum Boost is determined by the efficiency of the 'charger, too high, and if heats the inlet charge almost exponentially (ie, for every 2Psi boost, it DOubles the heat of the inlet charge !)

So, find the best inlet temp / boost pressure compromise and stick to that...

Personally, i'll never go back to a suck-through setup on Anything.. Blow-through works.

You Could modify a Weber / delorto for blow-through, box it and sit the blower slightly further out. . . not real hard....

OR, inject some fuel just after the blower, where the air is most turbulent and good a/f mixing takes place.....

Just ideas mind you (from someone who tossed blower / turbo around for nearly 2 years, weighing up the pros and cons.... - which one did i go for ?)

sc12's rotors are FLOURINE coated, dont now if thats any better than teflon? i failed chemistry

_________________

The coating on the rotors is not effected by the fuel if it was mine would have failed years ago same with the seals never had to top up the oil in the gear mechanism and I have had one running for about 5 years.
