Raptor's Port and Polish
Ok guys, I plan on doing a How-To when I get this all said and done, so this is just a follow-along thread.
Yesterday I did what I could by reoiling my K&N and also cleaning out the TB. Today I bought some rubbing compound and polishing compound, after the P&P so smooth things out some.
Also, I just got back from town. I went to AutoZone, Advanced, and even Lowes and none of them had the flap sanding wheels. So I'm looking online right now. The prices are all good (3-5 bucks) but most places are trying to charge me $15 for shipping....
Anywhos, I found a site, but lots of different sizes.... anyone care to take a look and offer an opinion? I know I need 3" wheels, but are those all bit sizes?

Also, I will be going with 60 & 180 grit, not the 120 as per Tally's write-up.

jokes aside, you guys are right- just sitting outside looking at it pulling everything off seems to be a bit of a hassle. has anyone here pulled off the aluminum intake manifold before? i'd like to get a process because this is something i eventually want to do.
but anywhos the truck is late, it should arrive any moment now and ill be off.

Basically, there is a 'boundry layer' - a thin area of turbulent air near the surface, and it matters not whether the surface is polished smooth or not.
Bottom line is it may not be worth the trouble to polish.
If you want to flow more air, make the hole bigger. But remember that in many cases automotive, air velocity is important, too. So there can be a downside to going overly large.

well.....im done. i even put some buffing compound and polishing compound when i finished and on my CAI tube.
Pros and Cons.....
Pros: On the initial test drive my "seat of the pants" dyno yielded considerable gains. 1st gear gets more low-end power, 2nd and 3rd's top-end are in love with me now.
Cons: Idle dropped from 850 to 750....ehhhh.....and my SG2 shows a TPS reading of 22 (should be 20). I took the buffer over the butterfly, so i may have knocked something out of alignment. Its not DIRE but not something I want permanent either. but the gains are noticeable. I'm no HP expert (as many of you know) but I'd have to say AT THE MOST is maybe 5 hp.
For the reasons associated with the risk in maybe screwing something up, I opted out of doing a write-up. I'm sure if anyone wants to do this later on, its pretty simple, but its just "iffy" right now until I can bump up my idle...
Note: the risk in doing this IMO is not great enough unless you are going "all out" I should say such as CAI, efans, UDP, exhaust and maybe turbo. doing this to a stock engine probably wont be worth it.
