Ok- What whould the effects, if any, on your car if you could cool you're intake charge air temp to say, 0 degrees F? Would you make massive power, would you throw a piston through your hood? Would it do anything harmful, or would it be awesome? Just curious, since my buddy raised the question to me, and I couldn't really answer him. I know that cool air is more dense, and that makes more power, but is there a threshold to it, or a limit of some kind? I'd just like to satisfy my own curiosity. Thanx

It would make your car awesome. That's why drag racers ice their intakes/what have you so that they can squeeze every pony they can out of the small things, such as intake charge temperatures.

You mean temp of air going into the intake or 0 degrees in the manifold??
i'd say about the same as driving arround montana in winter in -10 degree weather. after the turbo it'd heat up to about 10 degrees or more but still cold as hell and no ill effects. it wouldnt be that much more dense if it was just generally colder. depends HOW you make it colder too.
i always played with the idea of refrigeration chamber that ran off freon gass somewhere allong the ic pipes.

let's all put ice on our pipes and cause the condensation to get sucked into the engine..........smmmaarrrrt.
colder air is better, but anything below typical cool weather temperatures won't give you as much of a hp gain as you might think.
Well you don;t HAVE to use ice. You could use dry ice, or like americanjebus said you could incorporate the ac lines and pump freon to cool the charge. That would be trick.

The freon would not be able to keep up with the amount of air going in to the engine. But you could use a system that is already available, tested, and used by many turbo guys (and gals). Spray co2 onto your IC, (you can use nitrous, but co2 is safe and less $$ to fill) you can pick up kits at summit. Duane is running a kit, see his pics on his site.
Jimi: Should put the caveat : Not great if you have a Tube and Fin IC as you can thermal Shock it and crack the tubes....
Right, but you could use "DEI's" air intake charge cooler. It freezes that bubble to cool the air.

problem
jsut as with Crabs
put TOO cold an intake then you start going from cooling to creating ice shards
Trust me you don't want that You guys are just hitting the tips of the iceberg, here is the icing on the cake.

to follow up my original question- so what would the difference be going from say...60 deg F in your intake manifold to zero deg F? 10 hp, 20? How about if you could cool the manifold charge to -50? What would happen then?
As a general rule, for every 10 degree (Fahrenheit) drop in temeprature, there is about a 1% gain in horsepower. My grey matter is used up for today, you do the math.
So using that formula I could gain a whopping 13 HP if I could drop my intake temp to 0!
Not to mention the cost complexity and weight of a system that would be able to do this........:3d_frown:
This goes back to what I posted in another thread these aren't class race cars where every HP gained could mean a win they're big old heavy ROAD cars...
Sort of reminds me of Jamie on MythBusters, if there an easy way and a hard way he invents an even harder way!

^^^Yep, IMO, the main reason to do a cooling mod would be for detonation, not HP. And that frozen intake in that pic is retarded :nono:
i like the co2 intercooler sprayer also it can purge as much c02 as i want an cant get cought by the man for having an open nitrous bottle

WRX STI's use somewhat of a similiar setup except they spray a water/methanol solution across the top of the intercooler. I was looking into using Co2 when i ge a bigger turbo setup and a true FMIC
Here's where it get's interesting. Taking that general rule, the more power you make, the more there is to be gained by an intake temp drop, in theory anyway. Hypothetically you have a vehicle and each and every time you bring it to the dyno the ambient intake temp is magically 75'F. Each time you add a stage of tuning bumping you up in HP. You manage to drop your intake charge to 0'F. Here's what you might see.
250HP Dynoed @ 75'F
268 @ 0'F (+18)
350HP (+26)
525HP (+39)
705HP (+52)
