In for Hypers holy-grail radiator delete kit.

Shiny is worse than flat. light is worse than dark.

okay then, Mr. Science, it takes 0.902 Joules of heat to raise the temperature of 1 gram of Aluminum 1°C. It was 203 Joules of heat to raise ice the same...

...I think you know where I'm going with this.

Hold all street races in Antarctica!

BRILLIANT!

What if the aluminum is starting at a temperature of 1,221°F?

NOW WHO IS THE SUCKER

honey, any gold you gettin from your man aint gonna be actual and factual.

No, intercoolers made out of ice, duh.

Water is nearly free, just bring a couple to the track with you in a cooler next to your race tires.

I prefer the old tried and true window A/C unit mounted to front of car. Sleeper? No. Effective? Yes.

well, it would still take .902 Joules to raise 1 gram of aluminum to 1222.8°F. But it would be making its way through your block at that point...so mute point.

Are you sure?

Typically, the amount of energy required to raise the temperature of a material is linear, right until you get to a phase-change point. Then, a large amount of energy is required to actually make it change from one phase to another (eg: melting), and yet no temperature change is observed during this transition. (Enthalpy of Fusion.)

listen bro. i dont need your shit.

let's just go back to gold ICs.

thank you joe for paying attenion, unlike the latent heat of brain.

Google turned this up in a boat forum for preparing bare aluminum for paint:
  • Wash/degrease with detergent and warm water.
  • Wash again with detergent and blow dry. I use a leaf blower as I don't have compressed air!
  • Wash with 50% white vinegar and water to etch the bare aluminum and blow dry.
  • Shoot the bare metal with a thin coat of zinc chromate soon after drying to preclude further oxidation of the bare metal.
  • Shoot with 2 coats Rustoleum. finished!

The chemistry behind using zinc chromate is mildly interesting. Look it up if that's your thing.
