ok just figured i'd ask

how is the voodoo titanium shift knob heavier then the aluminum???? this doesnt make sense to me lol. isnt titanium a lot lighter metal then aluminum?

the arc titan. shift knob weights almost nothing and so does every other jdm knob i've seen.

Titanium is actually quite a bit heavier than aluminum. It's stronger, so you're able to use less material, which is why many of the "ti" exhausts are lighter.

but the voodoo are spun titanium so they weren't really going for weight savings

Not really, the extra weight makes your shifts alot crisper. In this case
the extra weight is good. Its one of the best mods i have done

Aluminum is a very cheap and light alloy, titanium is also really light, especially for how strong of a metal it is. Solid steel shift knobs... now those would be heaaaaavyyy! I think thats what the Abram shift knob is made out of?

And in shift knob case, I believe heavier is better since it helps with the throw =).

changing your gear knob was one of the best mod you've made?!?

really?

Time to review the Periodic Table of the Elements then (Google is your friend):

Now we can see Al (aluminum) at number 13, Ti at number 22, and Fe (iron/steel) number 26.

These are in order by (protons technically..but) molecular mass, or the mass of 6.02x10^23 atoms (1 mole as its called). Since your table doesn't give Masses..
1 mole of Al = 26 grams.
1 mole of Ti =47 grams.
1 mole of iron 55.8 grams.

Again this is ignoring density of each of these, crystal structure, and thickness required... but still

I think this is the source of the confusion. Items such as eyeglass frames can be extremely light when made out of titanium, but only because less of it is necessary. If the super thin frames were made out of aluminum, they would snap in half.

^ chem101 huh? LOL I'm in that class right now but doin pretty crappy cuz of all the damn conversions we gotta do... Pretty odd cuz all that stuff u just listed is what were doin right now heh
