I'm sure a lot of you have heard of ice boxes. Now disregarding the space issue, what do people think of applying an ice box in conjunction with an air - air intercooler.
I'm at the stage where I want to fit a FMIC but I also want to consider reducing the intake air temperature to sub ambient temperatures. Will the motor handle it? What do you all think?

I wouldn't think the pressure drop would be anything major? Here I did a small diagram to help illustrate what I mean. Please excuse the ms paint job I did my best with what I have.

a dry ice intercooler on a 1jzgte without a really good quality aftermarket ECU will drop power by 14%. Proven fact. A soarer was the first guinea pig when the coolers were being developed. the factory ecu wasn't mapped for the -50 degree inlet temps,and hence got confused.I think this may mean that a piggy back would be limited by the stock ECU values. your plan as above will work fine. pressure drop will be neglible because the flow rate of the 2nd cooler is high.drive around as normal,when you want an extra 100hp, put some dry ice in, and enjoy some really early boost! You need a good programmable ECU. I have thought of a similar plan, but feel i am struggling to find space for it. your thoughts???

The thing that would be difficult is getting a good tune that is suitable for non dry ice and dry ice. Usually you only have to use a different map for different fuels, (different boost levels can be done on the one map) but if the intake charge is so much cooler with the dry ice then I would think a stock ecu would probably do something similar to the coolant being low and put in a heap of extra fuel. Not that you can go much richer than stock anyway but that would probably be a contributing factor to the 50hp drop.
I have thought about this also. I am just going to do the dodgy cheap way and use some dry ice sheets and wrap a cooler pipe. Not going to give me -ve temps but should cool it down a little extra. Plus I have nitrous to cool down the charge also

I don't know why you would have both of them?
Any ecu that has air temp compensation can do it but personally I would be having a whole seperate map based on the cooler intake charge rather than relying on air temp compensation which is usually a blanket %change of the whole map.
If the power FC can store more than one map then yes it should be able to do it. I don't think many tuners are going to have much experience with sub 0 deg inlet temps on turbo cars though

dry ice is something like -70deg c. From the article I read about the ARE 180sx using big dry ice cooler they were talking about -45deg intake temps. At those sort of temperatures there is a lot more oxygen molecules. Should still be tunable by a good tuner though.

yes sub zero temps!!! power FC probably wont touch it- old technology now. Haltech E11 v2 will do it, and better. don't need two maps,just need to be mapped for those low temps, if and when they occur.Byron,why would you have an anologue SAFC still installed over a fully digital power FC???

Byron Yes, But you need to buy the Apexi Boost Control Kit for the power fc. You can change the boost settings via the handcontroller. Its quite handy.

All up to you really. It's probably cheaper and easier to tune then a separate EBC if you went with the Apex'i Boost Control Kit, seeing as that whoever that will tune your PowerFC should already be familiar with the Boost Control Kit.
You can purchase the kit on Ebay. Here's the link - Click Me I've dealt with these guys before, and they were quite professional although I do remember reading that one member (I think it was Ben Burgess?) that got stuffed around a bit with them. I purchased my GReddy turbo timer and EBC along with several other parts for my mates from them and they all arrived within a week of the purchase date in the condition that I would have expected.
You will have to purchase the Commander unit (hand controller) along with the PowerFC to take full advantage of the Boost Control Kit though.
You could go with an EBC if you really like the way it looks or something. All down to personal preferance and the tuner's ability in my opinion.
I am personally going to keep my existing EBC when I purchase my PowerFC as I have a theme going on in my interior and do not want to ruin it. Hope that helps mate

Now you've got me stumped! I like the look of those blue AVCR's but I hate having useless items in my car (like a monster tacho).
I'll probably just use an AVCR until I get a Power FC then when I get the Power FC (+ commander) I'll sell the AVCR (and make sure its still in mint cond.) and buy the boost control kit (just thought you all might like to know).

Byron, the advantage of having the Apex'i Boost Control Kit in my opinion is so that it makes everything look nice and neat. Some will say why have gadgets everywhere when the PFC Commander unit is all you need? Others will say the more gadgets, the better.
It all comes down to personal taste and opinion. Like I said previously, I'm going to stick with my GReddy EBC, then get a PFC and get the Commander unit custom mounted somewhere (I like everything to be nice and neat )
That reminds me, I gotta get an iPod dock custom made somewhere...

Dude any EBC is compatible with the PowerFC. Just make sure your tuner knows what he's doing when it comes to tuning the EBC, as it will have an effect on your PFC tune.
