Hypothetical Question/discussion

[billspreston01]

I've seen those cry02 setups tested at HIN and they're sweet. The best way would be to run a cone in your intercooler pipes before AND after the IC, and then a large spray bar mounted on the IC.
I don't think it would be useful going down the highway and spraying to try and gain the horsepower. But if you're a religious drag racer it would definately help keep the bay temps down for those long nights at the track when you're making back to back runs.

A friend of mine has already got a 10lb bottle and a small spray bar for his mkiv and he'll be getting the bigger bar and cones when he upgrades his ic and pipes.

slowdown your oponent by co2? the amount of co2 needed to hit the car with would be too much youd think..

You guys are just hitting the tips of the iceberg, here is the icing on the cake.

hmm

let see

if Ice is outside of that contraption. I wonder what is inside? Perhaps ICE? I wonder what happens when the temp is to cold.

anyone from the old school remember the freeing issues with carbs around the venturi section??

You guys are talking gains from an ambient temp. Imagine the gains from cooling the actual intake charge post-turbo, as with what the Mitsubishi is doing in that pic. Those temps are ~225°F at 10psi at the turbo elbow. Getting down to maybe 180~140 with a good intercooler. But since were going for cryogenics for cooling we will go with the 225°F intake charge.

(*the numbers here are completely theoretical, ambient temp, turbocharger used, and boost pressure run will all affect the actual numbers.)

With 225°F air coming out of you turbo:

At 250HP you would gain (+56HP) upping it to 306HP

Past here the numbers become purely speculative and only for comparison. The numbers will change because the intake charge temps will change based on the efficiencies of the turbo you use and the level of boost you have to run in order to achieve these higher numbers.

At 350HP you would gain (+79HP) upping it to 429HP

At 525HP you would gain (+118HP) upping the total to 643HP

At 705HP you would gain (+159HP) upping the total to 864HP

Now understand that the air coming out of a turbo can get EXTREAMLY HOT, especially if it’s run way outside of its efficacy range. So bringing the intake charge down to 0°F is extremely difficult if not impossible by using simple CO2. Liquid nitrogen maybe.

So yes cooling the intake charge via cryo is a bit ridiculous unless you have an intercooler as backup like Duane. Or you’re only going to be doing one or two runs.

my original idea was to run super chilled liquid from a resivoir (SP?) into a liquid to air heat exchanger (which would be after the turbo), in theory, the air charge would slow down momentarily and transfer most of the heat from the air charge into the liquid, and then that liquid be pumped in a cycle, keeping everything chilly.
