I remember getting a link to somebody who did M90 polishing.

I'm thinking about either picking up a polished blower case, or just another case and polishing it myself.

farnsworth does it ... i would like to polish my blower case but just to get the stuff was my biggest thing

Someone else does it too.
Look back at your own threads, posted info in there.

Just saw a huge thread on it over there. Polishing is bad for the heat transfer. Black actually is the best to reduce heat. Polishing looks good, but bad for heat. And you have to maintain it!

there is many links on the net for it on how to do it yourself

Actually, now that I'm tinking abotu it, does anybody have any info on Gen III to Gen V s/c conversions?

Actually there has been no proof polishing holds the heat in more. Chrome plating will. Polishing no.

Well, polishing will probably reduce surface area, because normally it's rather rough.

So I'd imagine it owuld lose a little bit of it's heat transfer ability. But I doubt it's any harmful amount.

true... the rough surface increased surface area for heat transfer. on top of that the heat of the blower will make the surface tarnish very fast.

the best way to increase the cooling ablity is to sand the paint of and have the bare metal.

Iirc Eaton said the rough finish had nothing to do with heat transfer just cheaper to manufacter.

The heat comes from the compression and very little is absorbed from the case.

Is there any way to polish it and then apply some kind of heat-resistant clear coat?

I mean, I tink I might een paint it *gulp* green after polishing it.

Green blower, green valve covers, green dogbones, mounts, and accents...

Zoops seal for finishing off polished parts,and for supplies and instructions go to Eastwood .Chico(pops)

Here's a shot of a self polished blower from a buddy of mine that moved to Boise Idaho. If you look closely you will notice details that you don't usually see from a vendors polish...... I'm waiting for another friend to send me a shot of his engine bay that I'm sure will inspire any doubters....

Whats going on with that gauge on the T-stat housing?

any rightups?? sugestions

Fuel Pressure. Not sure why, but I've seen a lot of FP gauges under the hood. Personally I have one in the cabin.

None that I know of....... I do know that a drill, and a dremel were the main tools used. A good assortment of sand paper for the manual cutting. If you have ever tried sanding wood smooth, you have an idea on how to get the aluminum shiny.
