Haha, goodluck
and I'm digging the gold foil

Thank you! The shop I got the rad from has it allllll over the engine bay of their time attack car, firewall, intake, lower intercooler piping, valve cover, anything that sees a decent amount of heat that is trying to keep something else cool they cover.

I will throw some on the valve cover as in the pictures above, and maybe a lil bit on the lower intercooler pipe near the downpipe/wastegat dump.

Lighter, thinner, better cooling, greater water capacity, relocates the hose further away from the heat, cores made by visteon to a spec slightly below the IRL cores







Forgive the JDM-DSM Zip tie, haven't decided where I want to move my boost controller to!

Really? Why gold foil? I hear metals are conductors and there are probably cheaper insulators. Diamond is a pretty good insulator, maybe get some diamond sheeting.

Gold is the best reflector of heat.

Go look at the engine compartment of a McLaren F1.

There is a big difference between insulating heat and trying to reflect heat. Diamond might be a pretty good insulator.... but I paid about 20 bucks(got a good deal considering I bought the rad at the same time) for about 4 feet of a 4 inch strip of gold foil.

Unless you can find a way to get diamonds to adhesive paper form I will still to my gold foil From what I have been told people see pretty significant changes in IAT's from foiling there intake system/intercooler piping, and sometimes even big differences in water temps depending on the proximity of the exhaust system to the cooling system, in my case the two are very close.



If it's on the Mclaren F1, it's good enough for me But the stuff used on the F1 is probably the uber high end stuff, couple hundred bucks per square foot.

Gold is also used on spaceships, etc for heat reflection. Gold is an excellent thermal conductor, which has the effect of 'wicking' away heat. You can experience the same thing by placing a sheet of Al foil over a roast, it retains the heat inside by reflecting it back. But if you have the sheet touching the roast, you can cool it off. Same effect for metal pot handles, a nice long metal handle will conduct heat faster than it can absorb it, thereby remaining cool to the touch.

Also, diamond is a THERMAL conductor, and very good, too. That's why diamonds are cold to the touch. They are electrically dialectric though.

you can buy diamond film, but it's EXPENSIVE, it's what they make these from

Nope it's a 3/4" tweeter. It does go to 100khz though (most tweets struggle to make 20khz).

Are you an audiophile too? That is crazy 3k better buy the best tweeter on earth.

Sorry, getting heat and electricity mixed up again. Stupid electrons, so small and yet so important.

Sales marketing at its finest.

Anything after 24khz is an absolute waste of money! You cant hear it, shoot you probably cant hear most stuff between 20-24khz or would care to anyway.

I am. Think of a thing you can be a nerd about, and I'm nerdy about it
And I do think it's nuts to spend 3k on a tweet.
Chris is mostly right. You can't hear much beyond 20khz, in fact, some people can't hear that high. However, you can feel it, according to some research I've read, having a 'supertweeter' does make a perceptual difference. I mean I can't hear 10hz, but I can definitely feel it.
I wouldn't know about the supertweeter though. Almost 0 musical recordings have that range. SACD claims to, but since most of the SACD titles out are remasters from old tapes, I doubt they have the range.

Now, the real reason that diamond tweeters make sense is the diamond diaphram gives the tweeter a very stiff moving structure, at a very light weight, which allows for better dynamic motion, control, and damping.
You can hear the opposite of good dynamic control and damping in a cheap aluminum dome tweeter which 'rings' on high freq sounds. The other cool thing is that the light, stiff diaphram allows the tweeter to remain 'pistonic' over a wider range of frequencies, which means less distortion.
The final cool thing, is that with most tech, this will get larger and cheaper, meaning one day you could have a diamond hood, not just CF... and how pimp would that be
