Looks good in this pic, looked even better when it was first done.


Tim, i thought u had an intake manifold that you made? is that an old pic of the twins or is that the new setup?

That's the old/first twin setup with the stock intake manifold Artie.

If you've got access to a blast cabinet, bead blast it carefully. Clean w/ air hose. If there's no electronics, you could run in it a parts washer, then a hot tank (depending on what's still on the manifold. Then dry w/ air hose.

I painted them w/ several coats of high-temp paint (rattle can) from Advanced Autoparts. Taped off the areas I didn't want to paint w/ painters tape.

I just did several valve covers for a Miata and MR2. Unfortunately, no good pics.

Steph, I did exactly what brain did. Ironically.. I used the red scotch brite pad you provided me with my radiator panel. Might be worth a shot since you already have them

I use the green 3m pads to clean everything I own that's not supposed to be shiny. They are awesome for scuffing wheels for paint too.

BTW, muriatic acid reacts rather unfavorably with aluminum. When I was a kid, we used to make acid bombs by putting a bunch of aluminum foil into a plastic soda bottle, then pouring in some muriatic acid (which is a common pool-treatment chemical), capping the bottle, and then running away very quickly. The acid dissolves the aluminum, producing large amounts of very noxious gas which ultimately results in the explosion of the bottle. The explosion, while not particularly lethal, is sufficient to demolish a closed mailbox. Or so I'm told.

LOL. That might be the route to go then. We have those same pads, in round, to run off of a die grinder. But will that produce a CLEAN and sort-of chrome look? The cam cover is chrome color also.

I posted a video of that earlier in the thread. It's pretty awesome.

probably running the throttle body in the stock location.

also dry ice, water and a closed bottle is pretty awesome..

i used steel wool and de greaser to clean mine...

Stephanie
pretty much...



I don't have the time or patience to actually polish up aluminum...but if you look at the dirty textured cast on my turbo housing...the entire thing used to look like that....just a wire wheel on on a hand drill...

used the same wheel on dirty painted MS pipes as well:
