7.3 IC vs. 6.0 IC
I have the original 7.3 IC that has the Alum end caps and tube connectors, but while contemplating the 6.0 IC I noticed they all have the rotomolded plastic endcaps and inlet/outlet. Is this a bad thing? I know the 6.0 IC flows more air and will reduce EGT's, but I just can't get past the plastic look of it.
what do yall think.
On edit: Yes I know I could order a new Spearco, or a Big DIIC, but I just don't have that kinda cabbage to spend right now.

Once it's in, you'll hardly ever see the plastic ends. Also plenty of folks have been running 40 lbs of boost through them without a problem. Go beyond that and there have been a few who have blown out the intercooler ends.
I guess the looks of the black plastic all comes down to tastes. But for functionality it's fine, especially for stock injectored trucks.

LOL... No worries on the plastic, but dont expect anything great from a 6.0 swap... I saw less then a 50 drop empty... not worth the time...

I think you hit the nail square, Tenn. Obviously, when not pushing, and even when pushing some, the existing 7.3 unit does a fair job. I would only expect the 6.0 unit then to make it's biggest impact when pushing beyond "normal" driving.
Joe and I have had different results with the 6.0L intercooler. On my truck, max EGT's dropped 100 degrees due to the intercooler alone. That's on a WOT run in the highest chip setting. Normal daily driving while empty, there's not much of a difference in temps. Towing, yes there is a difference when I'm going up mountain grades, about a 75 degree drop.
I think the biggest reason our results with the 6.0L intercooler was so different is I believe it starts losing it's efficiency when you upgrade the injectors. If you stay with stock injectors, then the 6.0L I/C will work just fine. But with larger injectors adding fuel and bigger turbo pushing more air, the 6.0L cooler is just too small.

But like I said before, if you plan on larger injectors, then you'll need something bigger than the 6.0L I/C to keep up. It's all relative, and your intercooler should match your application. Just like matching a turbo with your injectors. A 6.0L I/C is a good middle of the road upgrade, and cheap to do.
