01 Design Systems DIIS

Has anyone seen this or use one on acura CL

 

whoa ive never seen that before, since you found it, try it.

 

thats pritty funny

"Hey man wanna run?"
"sure whatcha got under the hood?"
"DRIZ ZY ICEEEE!!!"

 

You guys already have an "icebox" right under your nose.

It's called the Comptech Icebox. The box part is intended for dry ice.

 

I think your wrong.

If you put DRY ICE in a CT Ice box, the filter will suck in the melting CO2 wich will hurt combustion drastically causing a loss in performance.

The filter above just cools the pipe with dry ice, it's not ingesting CO2.

 

 

i wonder if the thing really works... would be interesting to find out a bit annoying to fill with dry ice tho...

 

Are they the same company who makes the Carbon Fiber wheels???

 

nm, answered my own question.

 

They're claiming 11-12 hp gain, but if you look closely, the gain with the dry ice is only 4 HP. don't think it's worth it, dry ice can be pricey and sometimes difficult to aquire. But a gain is a gain.

 

thats crazy..

 

Kinda funny frequently asked questions....10lbs of dry ice that will last for 5 days in the trunk..



1. Q: Where can I buy dry ice?

DRY ICE CAN BE PURCHASED AT YOUR LOCAL SUPERMARKET - IT IS VERY EASY AND
INEXPENSIVE TO PURCHASE. PLEASE DO NOT HANDLE THE DRY ICE WITHOUT GLOVES.

2. Q: How long would it last?

WE HAVE TESTED THE DIIS IN HOT RACE TRACK CONDITIONS IN THE SUMMER TIME, THE
ICE IS SEALED IN AN INSULATED CONTAINMENT UNIT - ONE FULL LOAD WILL LAST
ABOUT 1.5 - 2.0 HOURS - WE ARE ALSO DEVELOPING A CARBON FIBER INSULATED
COOLER WHICH MOUNTS IN THE TRUNK OF YOUR VEHICLE TO STORE AN ADDITIONAL 10
POUNDS OF DRY ICE FOR UP TO 5 DAYS IN THE SUMMER TIME.

 

yeh, so pretty much its a waste of money! stick to your COMPTECH ICEBOX!! who the hell is going to go to the supermarket in the middle of a race and get some dry ice...?

 

4hp gain is not worth the hassle.

 

Correct me if I'm wrong, but isnt that about the hp gain from a regular intake? Sounds gimmicky to me.

 

Its a bit odd that they have dyno sheets and dry ice in the intake ect.. but do not show a picture of a functioning system installed in a car .

 

Have used dry ice for long term cooling on camping or driving trips, and have yet to find it at a grocery store... have to go to an ice company... Finding an ice company could be an issue, depending on day of the week, time of day, etc... Can't see a compelling reason to buy it...

Cheers!

Walmart sells Dry iCe here in San Jose

 

I've heard of people packing dry ice on their intercooler before a drag race on intercooled turbocharged engines.

For N/A I would think their is a limit as to how much benefit one would get from a cold intake. Who knows, on a hot day, it may make a minor difference in HP.

 

all this damn dry ice shit makes me curious

 

 

actually most members are seeing gains of 9+ hp from the CAI intakes whether it be the aem or comptech.

but the 4 hp gain isn't that worth it.

But it's more hp/$ than the comptech axle back exhaust which most people only see a 2-3 hp gain and that costs $669

so do the math.... let's assume you get a 3hp gain from the standalone co2 unit.

comptech exhaust gives you about $223/hp
co2 standalone unit intake gives you about $65/hp

now, the co2 unit is something i WOULDN'T do. But IF the gains are legitimate. then it's a cheaper mod than the exhaust for hp gains.

but the exhaust is cooler and sounds better

 

if u want a true ice box or a true ice intake...spray some nos into it and see what happens...

 

I want the dry ice tank (box) in the trunk. Just so I can say taht I've had dry ice in my trunk for 5 days. Then I can throw it at people.

 

That Dry Ice will scream when it hits the warm alum box.

ieeeeeeekkkkkkkkkkk!!!!!!!!!

at the track: " hey, what's crying under your hood"

 

like with any intake, some cars see more gains than others. So maybe a turbo app can benefit from this more, not to make more power, but to maintain a cool intake charge reducing heat soak in the manifold that can cause detonation.

 

I have seen track cars use something like that. Never on a street car though.

 

You're right. My mistake.

I was thinking about regular ice.

My dad used to run at the track and told me that they used to do this all the time (with their home made set-ups). But they used regular ice blocks and a moisture barrier.

 

can someone explain to me why wouldn't water condensate inside of the pipe...??
i just know the throttle body love to sup up large amounts of H2O :wtf:

 

Cause the dry ice is packed around the outside of the pipe. See the pics? It's a box that is wrapped around the intake pipe.

 

I'm wondering how 'sealed' the box is. Reason I ask is, after the dry ice melts and turns to a gas, it will expand. That sealed box will turn into a bomb, so to speak. Be careful taking that top off. I'm sure it would be vented somehow, though.

A lab I interned at had dry ice along with a few classes during college. Take some dry ice and put it into a plastic container with some water...BOOM!!

A 2 liter bottle will hold over 300psi. They make great bombs. I reccomend putting one in a mailbox and hide to watch the fun.

 

Air passes so quickly through an intake....do you really think that little chamber is going to significantly cool any air being sucked in?

 

I didn't see any mention of heat transfer elements inside the pipe. If just flat walled tubing is used inside that chamber, there will be little effect at WOT. The air passing through at WOT will be above 250 inches per second. Without some elements there will hardly be any heat transfer in the roughly 50 milliseconds the air is in the tube.

 

That's exactly what I was thinking scalbert: having any knowledge of physics will alert you immediately to the fact that this thing is a scam.

LOL, I love that carbon fiber dry ice cooler for the trunk. I cant believe what some people will do for $$$.....better yet, how many people will fall for it

 

haha, I am sure if you fill it up with liquid nitrogen and you will gain at least 20 hp.

 

I plan on using dry ice in a portion of my intake. In the reservoir for the Liquid/Air intercooler though.

 

how much gain you think you'd get from that scalbert?

 

Mine is to cool the water to reduce charge temps. I should be able to get the charge temps well below ambient or about 30 - 40 degrees cooler than with just the water circulating normally.

Considering this is forced induction you could expect about 2% per ten degrees drop so upwards of 6% - 8%. Even at 6% on my car that would be about 22 WHP; or almost 30 WHP at 8%. With some more boost and 103 octane, 400 WHP should be easily surpassed.

 

scalbert you are a god in these neck of the woods
