cold weather

So today on the way to work it was -2°f, the coldest it had been here in atleast 2 decades.
Well the previous owner of my tc said it liked cold weather! I don't see it getting much cooler than this. But anyway, after my commute to work, i decided to give it a quick full throttle blast. Let me say I've never had this car spin from just laying into the throttle. That left me thinking, I wonder what difference there would be at the drag strip if you laid a block of dry ice on the intercooler! ?

The water would crack the exhaust manifold! The tires would spin in the water!

And, they wouldn't let the leaking car on the track!

However, converting to an air-water-air intercooler using an ice water tank and pump. Holy Air Density Batman..... :read:

Not ice, Dry Ice, frozen carbon dioxide. At a temperature of -109.3°F, when it melts it just turns to gaseous carbon dioxide. Its available at some grocery stores for shipping meats. Usually available in 1lb blocks, one would fit nicely onto the intercooler.
So I have to wonder, during drag racing, would you see a benefit to using it?

You'll have to run that one by a chemist. I don't believe it would work well in a closed container. I'm sure dry ice and water are not friends. And, just from the back of my head, I don't think NHRA or IHRA allow it.

Now cyrogenics is an option. Col down the fuel and the air, from the same bottle. It's currently in use and systems are available.

Look for "DEI CryO2 Intercooler Sprayer Kits", but hold on to your wallet real tight!

I'm talking about while using the factory top mounted intercooler, lay a 1lb block of dry ice on top. With the hood closed it wouldnt go anywhere. When it "melts", there's no liquid to drip on the track. Im surprised this thread hasn't had more attention. Maybe everyone isnt understanding what I was asking. Anyway, I cant wait till our local strip opens back because im going to find out if it makes a difference.
I have to say though, why wouldnt it? -109.3f laying on the intercooler, that got to lower intake temps and increase air charge density!

The problem I see is two-fold. First - if you lay a block of dry ice on top of the IC, you're going to be obstructing the airflow through the IC. Second - With the IC being directly over the turbo and exhaust manifold, that block is not going to last too long. Of course, if we're talking a trip down the strip it probably would be OK, but with the block cutting off airflow through the IC, it's got a lot of heat coming up from below to contend with. But I'm curious to see if it can make a noticeable difference in practice, so keep us informed when you try it out.

The blocks of dry ice available to me would leave some of the intercooler open to some airflow. And while you have heat radiating from below, you have the cold being conducted from the top.
It's not hard to break some of the pieces to be the optimal coverage of the ic. Now the big problem, our local track hasn't released the schedule yet for this year. So I'm anxiously awaiting to see the schedule, and make some passes. They usually start mid March, but as soon as I can, I will post the outcome.

Figure a update.
I happened to be in the area at the right time and bought 1.5lbs of dry ice on the way home. I made a pull without the dry ice then another 0-60. The dry ice I happened to grab was a chunk more than a slab, so ic coverage was far from ideal. That being said it did appear to do 0-60 quicker with the dry ice on the ic. Dont get me wrong, I'm not saying it works definitely, perception could be off. But at .99/lb and it lasted at least 10-15 minutes, even a small increase in hp isn't bad for the price for track use. Still anxiously awaiting the local track opening day!
