Yes now i have done it. I polished that plenum really good and it looks great. Im going to get pictures tomorow so you have to wait. 3 hours of hard work.
Everybody post your pic of your polished plenum, would be fun to see who got the best finish.

 

Only 3 hours? It took me a little more
Did you do it all by hand?

 

3 hrs? did you just do the top? How did you go about doing it? did you hand sand it or use power tools? compounds or sanding? Im up to around 3 hrs total with polishing mine and im at 400 dry. I think im gunna start with mothers and polish with my car buffer. Sound like a good idea? After mothers, what do you guys recomend to finish it off with?

 

i did my plenum in about 2 hours

i used a palm sander and only did the top, looks pretty good.

 

Took me an hour and a half to do mine, tonight i'll do the intake and polishing the lines in the plenum that will be fun
I need a new digi camera that takes better pics, my hp215 sucks and so did my painting. Tonight i'll polish the lines since my new wheels came in

 

I have about 4 hours in mine....just did the top....

 

I have probably around 4-5 hours into mine. I polished the top and sanded the sides smooth.

The next time I take it off, I'm gonna polish the whole thing.

 

About 3 hours...

Just the top also...

 

heres mine.....

 

I've got probably 2 and a half hours into mine between the grinding down of the front part (it was a pre 90 plenum) sanding the casting down, polishing the top, and powdercoating the sides and underside black.

 

Is there gaskets in there on yalls like runners/gasket/pln?

Cause someone uses a whole tube of gasket glue and no gasket and i cant get mine off to finish it...Any ideas?

 

Yeah i only did the top , i will do the rest this winter.
I wetsanded it by hand using 80, 120,240,400,600,800,1000,1200 and 2000 paper. After that i used a chromepolish and a polish machine.

 

use a scrapper dude, might take a while but .... i cut myself like 100 times doing it

 

 

Those look bada$$ !! But beleive it or not, the unpolished plenums/runners disapate heat better, hence keeping a slightly denser air charge. Just a thought!

 

hmm interesting, never thought of that before.

I like this cap I didnt do the polishing though. Looks good on the car.

 

5-6 hours

As promised one polished intake I spent 8 1/2 hours polishing it but it would have taken about 5. I wasnt happy how it was polishing out so I re hand worked the intake and repolished.

 

Very nice...I was looking at your price sheet. Your prices are very reasonable. For the amount of work required to get them to look that good.

 

Finally i got pictures. Im still waiting for the alu dist cover i bought from Thirdgenresource.

 

oh why not one more picture.

 

Yes im going to get large tube runners and then i will polish them.

 

Not too bad, hand polishing? While still bolted on I dont see how you guys can do it like that.
Good story behind this pic, I made the program, set the cnc up at college, and now I'm polishing all 70 of them so they can be givin out as trophies. the only thing I hate is the person who was running the machine let the 1/4 end mill dull and didnt replace it, so the sides are pretty gouged/burred up badly There I went and wasted all that time getting the spindle speeds and feed rates perfect for a superb finish, Down the drain
