Milano Supercharging

Greg,

It has been a while since this forum has been used, but I came across it and wanted to ask a quick question. I have an Eaton M62 and noticed that your kit uses the same setup and I was wondering if you would sell the kit minus the supercharger. I feel pretty confident that I could fabricate my own parts minus the crank pulley, but I would rather save myself some headache and buy the parts since I know they will work.

My kit won't fit the Eaton M62, it fits the Magnuson products MP62 (which uses Eaton M62 internals), and then only with a specific length nose drive and bypass valve position.

I would say it's an Eaton off a Mercedes. It looks like it's using L-Jet or Motronic. It looks like it's using an electric on/off clutch instead of a bypass valve and probably very low boost. There is a lot I can't see, and I don't know anything about that engine, but it appears to be a pretty cool setup.

Could it be an SC14 off a Toyota 1G-GZE? Does anyone know about these superchargers? They're really cheap, but I've heard the bearings are epoxied into the end plates, so not overhaulable. Capacity wise they're almost indentical to the M90.

Here's an interesting site : http://autospeed.drive.com.au/cms/A_2147/article.html

Hmmm interesting read. Here's part two of that as well - http://autospeed.drive.com.au/cms/A_2149/article.html

I'd assume there's a good reason for the use of the MP62 over an SC12/14 ignoring the new/used fact.

Thanks Rookie.

I was looking for that but couldn't find it. From what I've read, the M90 sounds too big for a stock to mild 2.5 and marginal on a stock 3litre. Unfortunately for us Aussies, it doesn't look like any local cars used the MP62 which seems perfect.

Those Toyota chargers are ridiculously cheap. I've seen them on Trading Post for AUD350 and even cheaper on Ebay. This makes them pretty attractive, plus they seem smaller than an equivalent Eaton unit, could be wrong though. Probably not a good long term proposition or particularly refined though

Scott, I think you are correct, it does look more like a supercharger off a Toyota. I reviewed that article and saw a lot of superchargers we don't have in the U.S. including that one. However they all appear to have straight rotors, probably two per side which I don't like. This causes the air to discharge in two pulses per revolution and between the pulses it flows backwards causing a lot of extra air movement. This is just one of the reasons these older Roots blowers heat up the air and require a lot of power to drive.

The Eaton's helical 3 lobe rotors constantly discharge air as they spin. The amount varies with the position of the rotors but they don't have the huge on/off pulses the older style units have. That's one of the reasons thier numbers are so much better than older Roots units.

Hi Greg, could you please give a link to your 'old site', which inspires people to build supercharged Alfas
