make a ebay install thread please we want results not how to's here......

 

first off,,,
this goes back a little ways,,, but if you, AWD94 guy, wants to quote some wikipedia at me... make sure you are referencing the correct heat exchanger model.

note that the air travels at a 90 degree angle to the intercooler core... this is a cross flow heat exchanger, not a counter flow.... big difference!!!

2nd... i will let the stead state comparisons slide, but make sure you note that the exit temp should be a mixed mean temp... go look at wiki and find out what that means...
I'll give you a hint... only the first 1/2 inch of the intercooler will actually see ambinet temps,,, in a thick core,, that may be .5 inches out of 3 inches... the last 2.5 inches of core depth will have air that was heated by the front of the heat exchanger flowing over it...

if you think about this... it will be impossible to have an exit temp the same as the ambient...

second... the amount of heat that evaporation will take away from the intercooler is tiny compared to the amount of heat the aiir flow will take away... intercoolers that spray water on the intercooler spray cold water,, because of the temp of the water itself,,, not your latent heat idea....
I am not saying that some heat won't be taken out of the intercooler that way,,, I am just saying that it is several orders of magnitude less than the air flow..
like 50kW to .5watts... such a small amount it can be ignored...

How has your testing turned out?

 

it doesn't... even if you drive thru a patch of fog like someone suggested..

these people are clueless!! i think all their knowledge has come from wikipedia...

 

This is exactly where you are wrong. The temp drop at the surface of the core from the moisture evaporating is a greater volume of temp than what is being added by the volume of heat going through the core in 1st or second gear.. cars stay in first gear like 1 second. How much heat transfer do you think there is in 1 second? Water evaporating from the surface cools the surface 4 times faster than the heat being applied by air. Water is 4 times faster at absorbing heat than air is. Water evaporating off surface is also 4 times faster at heat transfer.

There is no point in argueing farther this point. We wont be seeing any below ambient outlet temps in the conditions I am testing.

 

Maybe you are not interested in helping someone but ant_turbo wanted to see how this FMIC mounted..... If I can help someone out then that is would I am going to do, I am not a ***** like some people.

 

all this just to prove if the ebay intercooler is worthy? Considering how much info is in this thread i would have to argue that your testing is going to be accepted by those who want it and rejected by people that dont like the idea

 

has the test been done yet ? this thread is so long cant find it!

 

OK,, than help me understand...
I do not see why the heat transfer is dependent on the gear you are in...
air will be traveling over it at all times.. regardless if you are in 1st gear or second.. that intercooler will still have a fair amount of heat in it between shifts..


will you be trying an experiment with a water spray on the intercooler? it would be interesting to see how much water, and at what temp , you would need to get exit temps below ambient.. i think it is going to be a lot more than you think...and at a much lower temp.... i am thinking ice water... just a degree or two above freezing...

remember that mixed mean temp thing i mentioned? even with water, i would guestimate that only 1 inch out of a 3 inch deep core would ever have water on its surface... the rest will never have that affect from cold water..... and for the exit temp,, that will be an average of the rear of the core and front of the core,,, the front of the core will have to be much much colder than ambient..... just think about...

think about it...

my next point,, is unless you start your run immediately after starting the car,, and the intercooler starts at a ambient temps,, it will already be at elevated temperatures..

 

Has a date been set to put this to rest?

 

So when's this test starting? It's been a while.

 

No kidding, its only been over a month or more with nothing......... I hear crickets other than people bickering about technical data that isnt even from an actual intercooler test yet.

 

Quit scaring him away you vultures. The guy will do the tests when he can do the tests. Just bump the thread and leave it at that.

lol mad intercooler scientists. take it to the track, quit bickering over the net.

the mans got his science project and he is set to win first place on evolutionm.net

all the side trash and theories need to be held off... this man has brought us his test.

if you dont like it or disagree with results, his variables and way of testing, run your own tests. that simple. I just want to hear the results like most of you but this sucks to once a week come back to this thread and see someone new poke their nose in and try to prove they should work for lockheed, this aint no job interview or nationwide nasa project, its a freakin intercooler test between competitive brands in the hands of a private party.......

dont mean to **** no one off but seriously, maturity really being challenged that much?

just my .02 i know it shouldnt of been given but c'mon, you guys are making me the hypocrit!

 

kinda disappointed i just spent a bunch of time reading threads and still there has been no testing and numbers after over a month? Get to it which one is the best already

 

Wow, be patient people. He doesn't have to do a damn thing for you. He is testing to help the community, not to be your slave.
