Solex Manifolds

[John Straub]

Does anyone know what type of metal the "Solex" manifolds are on a 911? A magnet does not stick to it.

I want to replate them. They were kind of "gold" to start with.

Thanks,
John

John...the ones on my 66 looked like cast aluminum....

I'm thinking magnesium John.....

There are two kinds. you notice the difference in weight when you have each of them in your hands.

Hi Guy's,

I've seen three different kinds of manifolds based on the part number modifications (final two digits of the part number), but I've never seen any different metals used. They've always been magnesium. Here's a photo of that original coating:

Have you by any chance checked the manifolds of the 64 your friend bought of eBay last year? The manifold that I have came of a 64 and is def. different from all the others I have had over the years. I don't have a dig. scale but will try to get to one and get some pictures (some time).

Hi Richard,

Yes the 64 has manifold numbers .00 and they are certainly different in design. They have a single bolt bracket for the manifold cross shafts, so I guess there's a bit less of them, but I didn't notice a significant weight difference and they're not a different material.

I'll try and get a photo of all three versions in a line at some point.

That's the plating I'm trying to get, any idea what it is? Has anyone had them plated yet?

Thanks,

Hi John,

Not sure what it is, but I know it comes off really easily. It seems any sort of solvent will remove it. The first thing I knew of it was that I had a pair in a degreasing tank and they came out flat grey!

It's also quite iridescent depending on the reflection of light. They often look silver and a blue/purple sometimes. I'd be interested to know if it could be reproduced. Maybe I should take the nice set I have to a platers and see what they say?

Cheers

David,

If you find anything out, please let me know. I called the plater that I'm working with and he said if it's Mag...you can't put it in a acid bath before trying to plate. That will react with the Mag and eat it up.

I have some ideas I'm going to try.
