I understand what you're saying about the air flow, and that without everything working just about perfectly it would be pointless and possibly even destructive. I was just curious as to what comments 94ssei had on any changes whether they were good or bad. I presumed that he had the intake pictured earlier and that met the smooth wall/cone filter specifications.

Where can you get that sand paper? I've been wanting to do the same thing for my TB and */c inlet.

Check your local parts shop (Napa/Orielly/Advanced) that'* where I got mine. If you can't find it there or at a local hardware store I'm sure you'll be able to order it of the net somewhere like Jegs or Summit.

I just get the sandpaper at auto parts stores like Advance or Pepboys. They have sandpaper from 40 grit up to 2000. WalMart has it too in the auto section.

Looks good. Between this post and doing a search and reading alot of Willwrens writeups about TB/SC porting and polishing, i've decided to hit up the local salvage yards this saturday and see if i can't find a spare TB to go to work on.

What about the little material bump on the maf support, can you remove that?

Do you mean the very small 1/2 circle bump off to the right? It doesn't look like it'* necessary and you could probably grind that down (IMO) to be like the rest of the MAF support, though I wouldn't remove too much because you could have problems. I smoothed that bump a little, but not much.

Yeah, that was what I was referring to. Would it be worth anything to grind it down to match the other side of the MAF support? What does the master say, Mr. Wren?

I'd wait for the master but yeah, making it match the other side seems possible...I'm not even sure what that little bump is there for. Could be just for weight. :?

That little bump is an Anode to prevent the buildup (through corrosion) of Dichromium Phosphate on the bipolar junction of the MAF body during mid-throttle runs (in wet conditions).
