REFRIGERATED Intercooler-needs input

evaporator covered in ice inside your intake might reduce airflow if it got big enough... Thats what I was thinking...

Also, not thinking of "flooding" a conventional intercooler with refrigerant, more along the lines of fabricating an intercooler casing around a regular evaporator or flowing coolant through a laminova type intercooler which really arent that big...

I just looked the laminova Intercooler up. That look simular to the standard ATW setup that we have.
I was thinking the chiller would go after the heat exchanger to further cool The glycol.

Around- can you use your A/C compressor to cool you charge?
From what I've seen people have the wrong way of going about it and conclude that it is impossible.

It has been done plenty of times, there is ever a commercial unit available.

They all pretty much fail though because...

Can we overcome the power lost with the colder inlet temp and extra weight of the copper pipes, fans, chiller, and Condenser?

No you cant.
If you did, you would have just invented something like a perpetual motion machine.

The only time this will be useful is off the line.
Ie, give it a min or so to cool down the coolant mix before you accelerate.
Youll then get XX mins of cold intake air before the coolant mix warms up again.

No way will this ever be useful for track work or similar.

Im still up in the air about how important super rediculous intercooling really is...

Personally Im of the opinion intercooling only needs to be "adequate enough" for your setup...

Installing an intercooler designed to keep temps down on a 900hp motor is not going to be particularly useful or provide any additional power on say a stock engine. The added weight may actually hurt things.

If you want power, try focussing your efforts on things like fueling and turbo choice. THEN start thinking about the VE (volumetric efficiency) modifications like intercooling, custom manifolds, etc... Because lets face it, those things only provide additional efficiency, the only power adding modifications you can make are first and foremost related to fuel, and then the turbo. Everything else either provides a bit more efficiency, eliminates a bottleneck, or increases strength to handle more power. While the stock Intercooler is certainly a bottleneck when pushing the limits of the stock fueling system, just about any aftermarket intercooler will easily surpass the cooling requirements needed to keep knock at bay.

Intercoolers aren't so much intended to increase power as they are designed to keep your motor from knocking. If it does that, then its adequate. There are SOOO many more and cheaper ways to gain HP than dicking around with the intercooler...

Not to mention installing a huge intercooler designed for 900HP will induce massive lag.

I've got a sufficiant FMIC already, also have the original top ATA IC. Eventually I'll build one of these intercoolers and experiment with it. Got some good ideas from the input though.
If and when I build it ill post the results.

Why bother though? Like it was already said:

In a closed loop (ie systems tied to your motor) you can never get more power back than you put in due to losses (friction, heat, etc)

I'll prove everyone wrong or go out in a blaze of fire. Again, I'm not so sure everyone understands a "pump down system" which holds Alot of gas which can cool quiet a bit with a relatively small compressor.

You can't get more power over the long term with a system like this. Its physics. It can't work.

What you can do is move 'power' in time. In other words, run the compressor, cool lots of mass before a drag run (and turn the compressor off for the drag run) to get extra power for a short bit.

Then, all that aside, there is a limit to optimal intake temps. Too cold can limit power too...
