just wondering if the majority of you went with their 3 core sheetmetal units and hacked and sawed to make it fit, or if it fit somehow without doing that, or if you went with another aftermarket unit and how much it ran ya?

 

I'm confused. Let me explain.

You are referring to the ATI 3-core intercooler, correct?


....and hacked and sawed to make it fit, or if it fit somehow without doing that....

Assuming the above, why do you need to modify it? It's a bolt-on.

 

I would if I was going to get a ATI and intercoolers, I would talk to Willie.. He has Dual intercoolers... Seems like a great setup. Willie how is that dual setup working for you?

 

Couldn't be happier. The twin setup is very functional; I have three air temp gauges to monitor temps at the blower intake, blower discharge (pre-intercoolers) and after the IC's. This is visual proof the IC's work well. But even more importantly, there is no intercooler to impede airflow to the radiator, very important here in southern Arizona. This setup is also aesthetically awesome!

I'll be running some big boost (over 20) with my new setup, but first I have to complete my MAF to SD conversion. I'll also be using a 3-bar MAP, so tuning will take time. Until then, I have to limit my boost on my relatively new F1 to six pounds or so (very difficult to do).

Do the Dual Intercoolers cool more or less than 1 three core?

 

Do the Dual Intercoolers cool more or less than 1 three core?

According to my air temp gauges, the difference is not discernable. My primary reason for wanting to make the change was not because of air inlet temps, it was because the three-core impedes air to the radiator so severely that my engine was running significantly hotter year round. Even in the winter (if you can call it that in Arizona), my engine would run 180+ with a 160 t-stat on a 50 degree day. Since I replaced the three-core with the twins, my engine now runs slightly above the t-stat opening temp.

yeah my initial post was concerning the ati 3 core sheetmetal intercooler, being as it's core is listed as 27 inches (not including the hose inlet and outlets) whereas the alotted room between the headlights in front of the radiator is 25 inches.

anyhow im looking at custom intercoolers of less size, but im interested in your dual intercooler setup, whered you place them? what size are the units? custom or bought from a company? you using 3 inch piping? what blower/model are you using?

im looking to run over 20 psi, and so the intercooler id get (or dual) would have to have no problems with up to 1000 hp (im looking at 800 at the crank if all goes well) and also both would have to flow a rate of 1500 to "match" the blower output of the ati d1sc.

thanks for all your input in advance

Do not be concerned about these measurements. Let me assure you, the 3-core is bolted in front of the lower radiator deflector at a slight angle from horizontal.


....im interested in your dual intercooler setup, whered you place them? what size are the units? custom or bought from a company? you using 3 inch piping?

In the front corners, similar to the ATI fourth gen setup. The units are identical to the LS1 F-body application. They are ATI units. The twin system uses a pair of parallel 2-1/2" piping. They split after the head unit outlet, forcing air through each IC, then merging back into one pipe prior to entering the throttle body.


what blower/model are you using?

I recently sold my D1SC and upgraded to an F1.

Contact ATI and address your airflow concerns. I'm sure they can give you specs I cannot. If you'd like to see pics, click on "SC Z!!!" in my sig above, then scroll down and click on Supercharger.

thank you very much for your very detailed explanation and awesome job with the pics and info on your site!

im left with 3 questions at this point:
1) why did you sell your d1sc in favor of an f1? theyre roughly the same specs as i knew?

2) why have the pipes split up for each IC instead of one pipe going through both?

3) the pipe they merge back into, is that a 3 inch pipe before the intake?

thanks again for your help and input

Thanks! It's appreciated.


1) why did you sell your d1sc in favor of an f1? theyre roughly the same specs as i knew?

Externally, they are the same. Internally, the F1 has a 5.00/1 step-up ratio, whereas the D1SC is 4.10/1. This means faster impeller speed at any given rpm. Also, the F1 utilizes a dual-bearing (lack of a better term) setup as opposed to the single in the D1SC. This means the F1 has a significantly higher redline -- 70,000 vs. ~62,000.


2) why have the pipes split up for each IC instead of one pipe going through both?

This is ATI's design, not mine. I believe the twin IC design cannot support as much flow as their single IC's. All three designs that ATI manufactures have 2-1/2" inlets & outlets. Therefore by branching the path, each IC's is required to handle half the total airflow.


3) the pipe they merge back into, is that a 3 inch pipe before the intake?

Yes, as is the pipe between the head unit and the first "Y" to the IC's.


thanks again for your help and input

Glad to help!
