how about a aux mini [very little power drain] aircon setup, and use that to cool the post turbo air?
Not a great deal, I found this for a Lotus prototype
Mines bigger
well you live and learn.....
i like the simplicity of your idea.... and also the fact the intercooler does not take up much space.
He mentioned that in a response to my post.
Add air cond core to the same unit to run in conjunction with the air/water system.
That is a smart idea.
Better than mine of trying to further cool the water.
It would be a more direct system.
Wonder if its ever been tried.

So forgive my question.
But for a typical application, like city/highway power/towing power, an air/air would be best.
But for any application, where racing is an concern, or need to high power at low speeds air/water is best?
Both systems, of which could probably benefit from additional cooling.
Still needs room for the rad and pump and lines.
In the end it will take more room, but be a much better fit for his application.

Air to Air in my opinion is fine if you have enough front surface area for your intercooler to cool your turbo. It's cheaper and simpler and can work well in the right application but it's not better just different

i wounder what the math formula is to work it out?
calling all engineers
http://www.gnttype.org/techarea/turbo/intercooler.html
Let me know when you work it out, mean while I'll just plug mine in and see what it does
reminds me of, one of

Worth a read, lists the Laminova cores as a GM part.

It has been a pleasure to watch this thread, excellent idea and fabwork!
But with the dry-ice and aircon ideas coming up, this seems to get complicated!
And while were are at the the far-out ideas, what about this one:
Get a divers compressor and diving tanks. Drop the turbo and run the compressed air from the tanks directly in to the engine, compressed air freezes when it escapes due to the pressuredrop. I know this setup would not fit any standard applications, but for dragracing or hillclimbing perhabs?

The amount of power required in an airconditioning type setup is huge.
A small, low power drain system isn't going to make a noticable temp drop.
A 4 litre engine with 15psi boost at 2000rpm has to shed over 7kw of heat through the intercooler to get back to ambient.
Even if your first stage gets 60% of the heat out, your fridge unit has to pull out almost 3kw.

The site is a little disorganized, the info you need is in there but you need to download all the PDF's and pick through it. But i don't think they were intending it for people like me, I will say their R&D department is tops and are looking forward to my trials,
One gets to a point, where they might as well run NOS for short sections at a time.
I guess the other thing to consider, is the bottom end is probably stock, and can only take so much power anyways. But it does sound like a good idea. Would just have to rig up some system, so as engine RPM's rise, so does the amount of air delivered. Which I guess also makes me think. What sort of CF does a tank hold. And how many CFM will the engine use.Very true. Puts me back to the dry-ice/ice water thing. But that wouldn't last very long. And it's not very practical away from a ready source of ice.
I will have to think about this more. Very fun and interesting.
The key is probably in efficiency of the system.

Nick
BTW: Dougal, I like your sig. A friend of mine is a civil engineer working on a hydro dam right now. He loves it (for the most part).

NUP
How much did that set you back?
And how much will the whole engine cost by the time your done (if you don't mind me asking)?.
I see in your sig line, you where hoping for 400hp. Think you're on target for that?
Also just curious, have you considered adding nos (for that extra thick mud? Or would that be to much power, and you would start breaking things).
Also, what made you decide to build the 2F?
Ever think about going to a different engine?
(small block v8 chev or Supercharged 4.7 Toyota perhaps)

1 Still waiting on final cost.
2 15,000 Aus Est (givenupcounting)
3 Yes
4 Not allowed for competition.
5 I like beating V8's with a 2F and it's a Toyota, it belongs in a 40

One thing to remember with this system is it's cooling just as efficiently at idol as it is at full noise.
The final numbers at testing will be interesting, but don't you just hate waiting to find out
