Well we've been kicking around a couple of possibilities but I thought it might be worth getting some more tech input.
The plan: Lower the intake charge temp as drasticly as possible using an easy to implement mixture at the strip. Some considerations: Mixture temperature Heat exchange properties (water, alcohol, antifreeze, etc. all exchange heat at a different rate as well as have different specific heats to change their temp by a single degree I believe) Freezing/boiling point Brainstorm options: Ice water Saltwater icewater bath (lower freezing point) Antifreeze/ice mixture Add water wetter (better heat exchange properties) Dry ice with vented container and antifreeze/alcohol Those are the basics we've been kicking around. What's the consensus on the 'best' recipe for what to fill the resevoir with at the strip? A basic ice water set-up to achieve that 'Wintercooler' effect? Or something more exotic to supercool the intake charge? -------------------- |

Really nothing is better than pure water. Salt water is going to eat up the seals in that bilge pump unless it's specifically designed for salt water (wich I doubt) and saltwater is just really nasty to any sort of metal.
What more do you need than icewater and propane injection at the track? |

Ice water will only get down to ~34 degrees Farenheit or so.
Antifreeze would be able to get down to ~0 degrees F. I'm not partial to using salt on the system either but I thought I'd mention it. I hadn't thought about seals in the pump though. Good point. -------------------- |

I reallize the antifreeze would lower the temp more, but would it really be $$$ worth it? You want to be carefull though, don't ice up the pump or block the flow with ice and then it becomes useless.
As well, having about 250 + gallons of saltwater at home, you start to notice some things. (sorry to go off topic) |

dry ice melts almost instantly when touching metal, I can get ahold of some if you want to try it out let me know and I will get ya some

Antifreeze will allow colder temperatures, but it won't exchange heat as readily as pure water. Just something to consider.

Also anti-freeze will be a little more difficult to unload just anywhere if you need to flush the tank out to put in fresh ice. You would have to use the environmental friendly coolant to just dump it where ever you are. This also adds to cost and mess.
Even 34 degree water on a 80-90 degree day will make for some awesome intake air temps compared to us a2a guys! -------------------- In Loving memory of David T Crebo

if you go with antifreeze go with orange GM stuff, you can dump that whenever/whereever as its bio-friendly, and if you go water, water wetter is supposed to be great, I should be throwing a bottle of it at the redlines A2w setup soon.
I would go with ice water and a bit of dexvool(orange gm stuff) and maybe some water wetter, you should be able to dump it whenever/whereever, get a good cold charge, and get it a bit cooler than straight water, water wetter is only what, 4-5 bucks a bottle, and dexcool is like 9/gallon how much does the setup hold travis? --------------------

Run straight water on the street(you'll need antifreeze in the winter though), then run 70/30 antifreeze/water with dry ice at the track. You can always drain the antifreeze mix into a container and keep it around for when you need it. You also may want to bypass the heat exchanger at the track, as it might end up heating up the fluid rather than cooling it.

Free? Or at a discounted rate? If so, I will need a lot, come halloween. yes I have a hook up -------------------- ┌∩┐(◣_◢)┌∩┐

Water Wetter. I've used it with absolutely NO measurable gains on coollant temperature and consider it a waste of money.
If running the existing IC and tank sett-up with a mixture of coolant and regular ice. The mixture will soon become too diluted for any benefit if you inted to drain it into a container for re-use. If using dry ice I have no experience with that. BTW - Dexcool is the trash of anti-freezes. In short term applicataions it may be OK, but this stuff was designed to go 100K miles before it ever needed flushed. Now GM recommends fulushing it much sooner, while independant mechanics change it out for the good ol' green stuff to save the engine and components from undue corrosion and plugging of the coolant system. Good luck in any event. -------------------- In Loving memory of David T Crebo

Dry ice will just evaporate straight into gas and won't dilute the mixture.
Running antifreeze with plain ice would be a waste of time, as you can't get an ice-water mixture cool enough to freeze water anyway. If you've got a kickass freezer, you could make antifreeze ice-cubes -------------------- Eric Wort

Perhaps a slight mix of alcohol/water with the ice? Biofreindly and cheap. I'm told that the alcohol itself evaps too quickly to get any good heat exchange, but an iced down mix might be a beneficial setup. Just a brainstorm.
