this will be a long project as there is just alot of sanding/rubbin that will have to be done before its done. Bear with me and I will update pics when I work on it to show what is going on. After seeing thorco3's intake in person and reading his write up that made it seem so simple(it lies) I was determined to do this sooner then later. So why not now while I am in the middle of my stereo install........... There are some days I do not have the parts I need for that but I always have sand paper and elbow grease........

I bought the intake and it had been painted red previously. Didn't really care since I was going to have to strip the powder anyway so the paint would not be an issue. I use a chemical stripper I picked up at walmart. This is a citris based stripper so it doesn't have any bad fumes(orange), and isn't as strong but still works if you give it some time. I gave it a complete coat and waited about an hour and scrapped a couple of sections with a putty knife. Then I just put a super thick coat on, left it over night and the next morning most of the powder had shriveled up as though it had melted and either came off with water from the hose or with a steel brush. Took 3 coats to get all the corners but alot easer then sanding and cheaper then paying someone to blast it.

I didn't get any pics of the intake in its raw casted form and this is now after alot of sanding. I started first with a dremel and a sanding drum and small grinding stone to get the small areas and then used a larger drum and sanding disks and a drill to get the larger areas to remove the casting scale. Those power tools took off all the scale but left alot of tool marks on the intake that now need to be reoved so that meant there was alot of rubbing it.......... The first runner(bottom) here is almost smoothed out from the marks the power tools left. If you look closely at the runners above it you will see the tool marks that need to still be removed.

Once the tool marks are all gone and its all smoothed out then I will start increasing the grit# of the sandpaper until I am eventually up to 2000-2500(if my back and elbow are still working) and then buff/polish it. Like I said this will be a long project to do when I a can't work on my others but can't wait to see it finished....

Looking good. It's come a long way already. The intake looked like it was painted red with a sand blaster.

probably is a PIA for a car that is driven in bad weather but this car only gets out on nice days now. That first pic was with the stripper already on it but yea someone had to empty a whole can on it.

Yea it was red when I got it........ I have polished smaller pieces before but never anything this big. I hope it comes out as nice as thorco3's as when I saw that thing in person it really was striking...

Fell asleep early last night, woke up really early and decided to spend some more time on it. Today I attacked the 2nd runner, smoothed some small spots in the 1rst as well as the flat areas on the top not shown. Gonna keep rubbin that bitch till the genie pops out..

red wasn't my thing, neither was green actually as that is what is on my motor now. After I painted it I just didn't like it at all.... I will probably strip and polish that one to sell it after this one is done and ready to install.

still rubbin it, progress seems slow but big problem spots are becomming smaller and smaller. Probably have 15 hrs into it so far. I would like to think I am half way done now with the flat spots and the bottom 4 runners fairly smooth now. I am sure that is not the case as I still need to get into some of the corners of the curves and I know the little details in this will take 2-3x as long as I would like to think they will.

there still are some small pits that I am wondering if I will need to have filled in a spot/tach weld. Seems like no matter how much I keep sanding I either can't get below the ones I have or if I am finding new spots. Hard to see in the pics and not immediatly obvious from even a small distance but that crap will drive me nuts.......

Looking good! I got lucky and bought a Motorsport version that's polished. Of course it does not have the cool Cobra plaque, it just says Motorsport SVO. They do look good polished.

A dude on craigslist here advertises metal polishing, after seeing how many hours you have in it, I'd drop a c-note without even thinking about it to have someone else do it. lol

if I had someone I knew that did it for $100 I would pay for that too but I don't see anyone charging that little for it. It is a pain in the ass but I am just doing it 2 hrs at a time and with some headphones/music I have done worse/harder projects....

Yes by rubbing it I do mean by hand. I initially used power tools to get the casting scale off of the intake and now I am just going behind it and trying to get rid of those marks the tools made. If you look at the top and compair it to the bottom you can see the tool marks on the top portion that I have not started sanding yet.

the one I currently have on the car is painted and I have just never been happy with it. Its thorco3's fault. Since I saw his, I have had to have sooner or later..... I blame him for my sore fingers/shoulders from this.

thorco3 - my fingers hate you...

Been spending time on it in 2-3 hr blocks, basically till I can't hold the sandpaper anymore. 95% of the runners are smoothed out now with the exception of some corners at the bottom and some minor pitting. I also started on the throat but these pics do not show it.

So now like I said earlier, am I nuts for liking the satin finish that it has at the moment? Clean it up a little more but otherwise for some reason the more I see it like that the more I like it..
