air to water intercooler

[GLHS]

I have before and after pyros on my intercooler.
A rough estimate of the air going into the intercooler is about 10*-12* for every lb of boost. The outlet side of mine is always about 10-20* above outside air as long as your boost pressure is less than 10 lbs.
At the extreme end of things @ 44 psi the inlet side pegs my 425* guage very quickly and the outlet is about 160*. I have never seen outlet temps get over 175*. It takes about 38-39 psi to get the guage to peg on the inlet side.

Keep in mind I am running a Hellmann custom intercooler which is more effective than my previous Banks intercooler which, was more effective than the factory stocker.
IMO, I believe the powerstroke intercooler most guys are running is as good or better than the Banks one.
For every day driving, you want an air to air intercooler.
They use water to air intercoolers because it is more compact and cooling the air down to 195* is still better than 300-500*.

so in a stock form truck would it be worth the trouble

hey-Hey!!!,
recall from chemistry, P1V1/T1=P2V2/T2. Now T is in Kelvin and we'll neglect pressure drop across the IC to simplify...so V2=V1(T2/T1) with T1 being the hot side of the IC. Call 425 about 200C or 473K and 160F about 75C or ~350K there will be about a 25% increase in density of the pressurized air... Just so you can dispense with the 'I'll never use that stuff in real life'...heh-heh-heh.
cheers,

did anybody else understand that one or am i that dense?

I will 2nd that and raise him a " if fuzzy wuzzy was a bear and fuzzy wuzzy had no hair then fuzzy wuzzy really wasn't fuzzy wuzzy".


Guess I need some schoolin

lol funny sh!t

GLHS --- thanks for the good info with you having 2 air temp guges
may I ask --- what air temp guges do you use ?

ellis93 ---- yes there is a lot of "duesh baggery" of street fire --- there is ware my vids are hosted at for free

hey-Hey!!!,
Y'all dissapoint me with your lack of interest in what is going on, and how it works in this stuff we use everyday. Failure to understand this stuff makes it hard to use any other shopping skill besides, 'I sawr it work real good fer him' when it is time for the next upgrade/improvement. How can one be sure you're not jus' getting a bottle of snake renderings? Allow me to link the wiki article on the Ideal Gas Law, http://en.wikipedia.org/wiki/Ideal_gas_law

What I've done is some manipilation of pV=nRT ( see the article to define the constants ). With our IC's we wish to cool down a volume of compressed air. Actually it is a flow, but it gets treated as perhaps a moving volume...it doesn't make any difference. All this talk of large temperature drops with a good IC got me wondering, 'how much difference in density will it make with the numbers provided'? He went from ~450F to 160F...pretty damn fine to me. Soooo, back to the equation defining the Gas Law...what needs done with pV=nRT so it gives me the answer I want to calculate. We'll take a volume of air above the IC, it is at pressure_1(P1), volume_1(V1) and temperature_1(T1 ), and it will have the same number of air molecules once we pass it through the IC( assuming the boots aren't leaking ) and we then define its pressure, volume and temperature with 2's so the n is the same and we can remove R( algebraic slight-of-hand if you will, cancel it out, etc ). in any case the PV/T quantity both ahead and downstream of the IC is set equal to the same nR, so we can set p1*V1/T1=p2*V2/T2. I ignored pressure drop across the IC, and re-arranged to see how much volume changes after cooling from 450F to 160F( now look up a Farenheight to Kelvin temperature converter if you want a better number ), install the numbers and go...v2=v1*(T2/T1).
cheers,

---don't mistake my suprised sarcasm for denigrating a *POSSIBLE* lack of education/understanding. There's all sorts of useful stuff, that when taken as an abstract concept is quite painful to learn and very boring. Doesn't mean one shouldn't make the effort. How thick does that bracket *HAVE* to be? What happens if the right answer is twice as thick as you built it? Is it somebody dead, or is it just a walk home instead of driving?

I just had a flashback nightmair if a math class I got a A in but every time this nightmair flashess it ends with a nun cracking a rooler over my nuckels for beeing smarter than she was ---- EEEEEKKEKEKKKEKKEKKKKKKKK

going for a motorcycle ride now to clear my head

[ellis93]

Mr douglas that is some kind of cool info. I'm gonna tri to figure it out, if in doin so I get stumped may I pm u. That fuzzy wuzzy stuff was just a joke from a dude that has no clue about that stuff. Maybe I can get one from the link u posted.

PM away ellis93, I'd be happy to answer( or help find an answer ) to any question you may come up with. Or maybe ask them here...
cheers,

You should have tried to be smarter than her in spelling

hey-Hey!!!,
I took a good look at the water/air unit installed on the new Ford 6.7 today. That is one nice unit, and it'll fit outboard of the turbo if the washer bottle can move a bit( and I am sure it can ).
cheers,
Douglas

You would definitely see a benefit reducing air to air inlet temp from 500+ to 195ish degrees. As long as the water to air unit isn't more restrictive than the air to air. JMO.

The in and out pipe is 2 1/2. I think it will flow. Problem I have now though is the 90 on one end. Gotta make it straight to make this thing work. Its cast alu that's gonna take heli arch weldin.
