L67 Throttle Body
Polished
This is marking the END of the tough stuff! At this point I wanted to try and make the texture inside the throttle body smooth.
Not knowing much about the process, I first tried "polishing" stone bits for my Dremel. That just gave me a
consistant texture (and filled the pores of the bit with aluminum, not doing that again). I got better results using a fine grit
sanding drum and sandpaper flapper. That helped smooth things out, give a consistant texture, better then the polishing stone.
To finish it off, I used a bit that resembled a Scotch Brite pad, chucked that in the Dremel and it did the finish work.
Once polishing was done, I just took some pics of the exit flare with and without the gasket I used for a guide/template.
And the throttle plate. I did a couple of things here. First, I obviously cleaned it up. After that,
I used various grinding stones on the edge all the way around (this was to give it a sharp edge for air to flow against, may not matter much,
but the idea sounded good). Also, the screws holding it into place, I grinded them so they would be flush when screwed into the
shaft holding the plate.
I've read of other things people have done here. Some will remove half of that shaft, others will grind both sides of the shaft to
make it thinner (leaving less material to obstruct air flow). I opted to not do anything to it. Given what I have already
done, and the larger through this throttle body has, I did not feel altering the shaft holding the throttle plate would make a significant
difference. I admit, I have no research to back up any method, it's just my gut feeling on the subject.
