I ahve all my intercooler parts gathered now. Am going with the SD 7.3 all metal cooler. Is the 6.0 being 30% larger really much better in lowering egt's compared to the smaller 7.3?
Thanks

 

Yep, 6.0 Runs cooler and will flow more air. IIRC you will need to adapt it with rubber boots, the inlets/outlets are different size from the 7.3. Since you already have all 'your intercooler parts gathered' it may be better to stay with the 7.3 but If you have the option, go with the 6.0 cooler.

 

is the banks better than the 6.0? I haven't installed mine yet

 

I know TJ had the 7.3L in his and then swaped to the 6.0L. So when he chimes in he will be able to tell you the differnece it made. I have to 6.0L in mine and it seems to work pretty good but never had a 7.3L in there to compare it too.

 

Yep, the banks flows better and runs cooler than both, but...is it worth it? Since you already have it then......

 

the 6.0 cooler has the same outlets. its just a little trickier to make it bolt in. well worth the time doing it though

 

One of the 6.0 cooler connections are larger than the other. I believe its the driverside and its 3.5 inch or maybe 3.25. I can't remember ecactly. I went from the 7.3 to 6.0 and didn't notice any change in temps. EGT's are very difficult to gauge. The Superduty guys make this swap as well and all say that empty there is little to no change but when towing the 6.0 cooler runs 100-150 cooler.

Comparing the 7.3, 6.0 and banks coolers I will give you some dimensions. I don't know flow ratings though.
here are some hard numbers
Superduty 7.3 29x18x2 cu inches 1044

Banks 7.3 29.5"x18"x2.25" 1194 cu in

Stock 6.0 26.5"x21"x2.5" 1391 cu in

The 6.0 cooler is the largest of the three. If you want the best in cooling and performace Spearco and The DI IC can't be beat.

 

thanks for posting good info tim!
one thing i always wundered about a big I-C is how much they restrict flow to the a-c condenser?

 

I have not noticed any decrease in A/C performance. And I have only ever heard of one person saying otherwise but it was the consensus that he had other issues.
