Alright i was bored so i finally went to homedepot to get some blades for my dremel and take a look at this lil beauty. Bought a bigass kit for 20bucks and it was the last one on the shelf

Says a $70.00 value and i kinda believe it because half the crap on the shelf was atleast 10 bucks or more for a 5pack of blades.



Now onto the TB, I cut the airhorns off and rounded the edges down but i want to clean an polish the whole TB but my question is, what's the best chem to do it ? i know how to polish sheetmetal and steel but what is the best way to clean up and put a nice shine on alum.

 

Looks like a good start , im gonna do more myself from now on, i used to get tired of messin with stuff and almost got the attitude of having some one else doing the work instead, just got lazy i guess not good.

 

You wanna get Tripoli and white rouge. Do the tripoli first then the rouge.


After major amounts of sanding that is. The idea is course sandpaper to get the major defects out then keep working finer and finer. Then use the tripoli then rouge

You can get them at Home Depot where the buffing wheels are

 

What's the best grit to use on alum, theres no major gouging on it, just mostly really hard to level out the tones on it

 

When I did mine, after getting everything shaped the way I wanted it. I started with a 1500 grit wet sand, then moved up to 2000 wet sand. After that I polished it with some rubbing compound and it buffed out to a mirror finish.

 

did that take out the swirling ?

Edit: also did you notice any throttle response, im not expecting anything i just wanted to do it for something to do but if i actually get something outta it for free then cool

 

Absolutely. One thing you should note is that I wet sanded the hell out of it (I'm a bit a of a perfectionist). I did notice a "off the throttle" increase.That went away though. I think the CPU relearned itself.

 

then why even do it because the ECU is just going to adapt to it and force the IAC to adjust to compensate just as yours did ?

 

I did it thinking that the faster throttle response would be permanent and not temporary. Maybe someone else had a better outcome.

 

"best way to clean up and put a nice shine on alum"

I use baking soda in a small sandblaster, then rinse with warm water.
