Hi, I was reading about a different type IC here and now cannot find it. I want to revisit its build. It had two side tanks that seemed to block the radiator and condensor pretty good. Where did I see it?

 

I think I know which one you are talking about. I think it was in the group buy forum.

**EDIT**

Here it is

yep, thats it thanks

I'm thinking I like this design more and more

 

imo its a bit ugly looking through the grill, but just my opinion.

 

I'm wondering if I could set up the high speed fan to switch on and to pull air through it at low speeds, ie; stop and go traffic and high temps, like my Diesel truck?
Its a really well made and designed unit and that makes it a little better looking

 

I have this intercooler and it works pretty darn well. Im happy with it.

 

That cooler has nice frontal area, but not enough core thickness for use under repeated acceleration. Below are some datalogs of the Helix Stepped Core Intercooler. The SCI has incredible consistency run-to-run and the highest efficiency available. Because of the bull-nosed bars in the tanks, there is a mere .5 lb. pressure drop at 250 whp.

 

a thin core is good. short tubes are good

 

That depends on flow velocity. Short and thin are good for low velocity flow, but not so much for high velocity. (like intake air)

 

What factors affect the pressure or flow loss?
The internal flow area is the major controlling factor. Tube length is the second biggest consideration, as a tube twice as long as another will have nearly twice the drag at the same air velocity. Tube entry and turbulator density play small roles and can be considered insignificant. When configuring the orientation of the core in a given space, always position the core to offer the shortest length tube and the most number of tubes. Clearly, this optimizes the internal flow area.

What are the differences between short tubes and long tubes?
The longer the tube the greater the pressure loss accompanied by a slight increase in efficiency.

Does the length of the tube affect efficiency?
Very little. The most heat comes out of the tube where the temperature difference between the inside and the outside is the greatest. That exists in the first couple inches of the tube. The last inch of the tube, wherein the charge temperature is rapidly approaching the cooling media temperature, will transfer very little heat, thus being of minor use.


What factors affect efficiency of an Air-to-Air Intercooler?
Frontal area: This is a rapidly decreasing function. If the proper core size is used, then doubling it will definitely not double the efficiency. More likely, doubling the core would raise the efficiency about 5% and cost twice the necessary amount and add substantially to the weight.

Plate area: Plate Area (the sum of the Core-Plate Area which is exposed to the Atmosphere) is directly proportional to the frontal area and the thickness.
Thickness, however, is a double-edged sword. With the greater thickness, the plate area increases but less ambient air can penetrate the thicker core to offer cooling.

Ambient air quantity: It is very important to insure that air coming in the snout of the car will actuallygo through the intercooler

 

Oh we could go on and on with heat transfer, fluid flow, thermo discussions all day long.

Bottom line? I don't think any of them are significantly better or worse than another. (Helix, Forge, Alta, or this other one.) They are all a lot better than the OE one.

 

Our intercooler does an excellent job of reducing IAT’s under repeated high load operation. Using a Mustang dyno, we repeatedly performed groups of 4 to 5 WOT runs on both the stock unit as well as our FMIC. We used no cooling fans and did not allow for cool down time between spins in an effort to induce heatsoak. We also gathered our test data on the track at Watkins Glen during numerous events as well as on the street. We literally have hundreds of hours into development and testing of this unit. Our FMIC was co developed with Bell (one of the world’s leading intercooler manufacturers) featuring a proprietary core extrusion. Our FMIC was designed in house, and is exclusively manufactured using American-made cores, and american skilled craftsmanship. Some companies may claim American-made because they take a Taiwanese core and Chinese end-tanks and weld them together in the U.S. Be careful of this distinction.

 

Bell wrote the book on intercoolers

 

Except that all restrict the air flow to the radiator, some more so than others.

On the JCW you eventually run into high water temps if you are running the car at the limit, tuned with a bigger IC.

Most people are blissfully unaware of this, because there is no water temp gauge in the car, and most people don't data log it.

well I wondered about that same problem but the manufacturers are saying otherwise

 

Hi,

I am talking about the track, under extreme prolonged abuse. It won't happen on the road.

Also, I am not talking about any particular cooler. This can happen with any cooler
