any ideas on how to obtain a finish like this ?

Hmm. Strip the chrome. Krylon has a silver spray that is just for plastics. It comes out looking very "steel-ish" or just use steel colored hobby paint. Then create a wash using some black india ink or paint and go to it.

For the blower texture & color; try using a spray can of "cast - cote" get it from most auto parts stores..matt

Try Testors Metalizer followed with a wet coat of Dullcote, let dry, then apply a black wash(or darker Metalizerwash) followed by another shot of Dullcote. If this ends up too dark you can drybrush metalizer(same or a lighter/darker color to suit your needs) over it. This can be followed by more dullcote if a flatter finish is what your after. I like to have the full range of Metalizers on the bench and can get many different effects and enjoyment using these methods. Good luck

All the raw metal surfaces on here,except the headers, were done this way, IIRC the intake is metalizer stainless steel, and the cam covers are buffing aluminum

This "mag" was done the same way, but using Metalizer magnesium

Use MM metalizer in magnesium....shoot the paint "dry" by backing up a bit....this will give you the look and texture.

The wheels on this were done this way

I have gotten an effect similar to this with Testors aluminum with a black wash over it.
