You could always give me yours of the EB Beast....

Shoulda went out last night, massive action and many quick whips.

 

What do you guys think a car running race fuel as opposed to meth/alky would benefit from: a) more IC heat dissipation b) better IC flow?

 

Really? I didnt know it was going to be good last night, I would have went out.

 

I think it would be helpful to edit the first post with a ranking for each core in each test ... for instance:

Flow Test:
Baseline flow - 813 Hz
----------------------------
1) So and so big IC core - 755 Hz
2) Other guy's intercooler - 650 Hz

And do something like this for every test so the readers can do their own comparisons. It would be easy to see that IC A flows better than IC B, but IC B has a lower pressure drop and better heat dissipation qualities.

 

Does the large Ebay I/C have any piping kits that it will work with besides the "universal kit" ? It's inlet/outlets are 3" so seems a waste to bolt up a 2.5 piping setup?

 

Hey Dave me 2

 

Dave I have always intended to test your core as it is likely the benchmark to test against. I dont have one here yet. I keep missing the used ones that pop up for sale.

 

94awdcoupe- I read alot of your post, and to me you seem to know your sh*t.

With all the testing youve done thus far witch FMIC would you be comfortable buying?

also in the IC pics- who makes that big one? Its the 3rd one. the Big boy!

 

Wow, interesting to see the greddy 3 row supra core 599hz vs the ebay 4" intercooler at 604hz, these cores are the same dimensions and share the same performance

I think that a higher flowing IC will definitely result in increased low RPM torque and power, and will also be better suited for stock turbo car's since smaller turbo's don't generate much heat. With larger turbo's that tend to heat the air much more, its very hard to say what the hell is going on. There are a lot of variables here: air flow, pressure drop, and the temperature differential (not to mention the use of meth just complicates things) all of which are mathematically/physically related. Considering the complexity of this equation, a higher flowing IC such as the Ebay unit might not be the best choice for a high horsepower big turbo engine, but flow alone probably has little to do with overall performance. As mentioned before, to get more significant data, heated air must be used, and you will also somehow find a way to increase the flow (you need a MUCH bigger fan or maybe a compressed air tank) to more accurately simulate the output of a turbo. Perhaps try getting a more powerful fan that blows through a plastic PCV pipe with some kind of heater grill in the center that heats the air up before going to the MAF and intercooler. With increased flow and heat, the pressure drop and temperature differential will be larger and easier to measure. Good work so far and thanks for sharing!

 

small turbos generate more heat due to back pressure in the turbine housing.

technically a cool charge increases torque, that's why alkie gets a torque boost.

 

Small Turbo's probably heat up more of the compressed air that they output, however, the total amount of heat being imparted into the air per unit of time (joules/sec) is much greater in larger turbos (because of the higher flow capability of the larger turbo's). If you compare two turbos, one large and one small, both running in their optimal compressor ranges, the amount of joules per second of heat transfer will be much higher in the larger turbo.

 

that is not what you said. you said "smaller turbo's don't generate much heat" "With larger turbo's that tend to heat the air much more". those are both incorrect statements even based on what you just said. if you want to talk about bulk heating then do so. if you want to talk about absolute temperatures then do so.

what you should have said is big turbos heat up more air. not heat the air more.

small turbos don't heat up a lot of air, but they heat up a little air a lot.

 

Yeah I must apologize for not making it clear. I thought it was obvious I was speaking about "bulk heating". Small turbos may blow a lot of hot air, but since its only a small flow, its not as much heat when examined over time compared to large turbo's. This is exactly why big turbo's need big intercooler's, and is why a high flow intercooler might have problems (depending on other variables besides overall flow of course!) properly cooling the output of a large turbo, and is also why this test requires a better/more powerful/compressed/heated air source to reveal any significant results...I am not trying to dog 94awdcoupe's work, I think what he has done, and what he is trying to do is absolutely awesome! He knows his stuff, and eventually good results will be had, and EvoM will reap the benefits.
