requesting pictures of sandblasted plenums

**i3igpete** · 10-05-2010, 09:07 AM

looking for pictures of sandblasted (non polished) plenums. i'm wondering if the casting roughness will come out without the time/cost of fine grit sanding and polishing.

Sandblasting does make it smoother but it still leaves a fair amount of texture.

Pete, I took a wire wheel on my drill to the plenum. Took about 10 minutes and looked a ton better than stock...

With an 80 grit blast, yes. ...but you then have an 80 grit surface to smoothen out.

Don't have any pics of the plenum I did... The owner loved the color and texture of the freshly blasted piece so I just installed it on his car as it was.

I think I have a spare NA plenium and lower plenum I can blast and take pics of if you'd like to see it. Remember though, the NA parts are painted so they're going to require a bit more blasting but the surface will appear the same when I'm finished.

My previous job I did a bunch of sandblasting. Aluminum oxide, steel shot and glass bead. Are you hoping to save some work by blasting it first then sanding/polishing it? I would think you would save some time if you knew somebody that had the stuff but I wouldn’t run out and buy it.
