Intercooling question

Has anyone ever tried running the ATR intercooler system (or similar) without plumbing in the lower stock heat exchanger? Just wondering if carrying the extra weight makes a difference in cooling efficiency.

Without the coolant circulation I believe the W2A IC would be pretty much worthless.

Re: Intercooling question

are you refering to the secondary cooler that was sold that sat in front of the radiator and acted as a second cooler to further cool the fluid from the upper HE? If so I could see where your going with this, you would loose a few punds from the lower unit and brackets. As long as you installed a pump of somekind it would still function. I do not think it would be able to cool as well though, at least on its own...

Yes, this is what I meant...Plumb in a pump and use just the aux cooler. Would seem to me that it would be better than just the stock set up. I just don't know if the aux cooler has enough capaicty to cool by itself.

I did this with a ShurFlo. Ambient temps were slightly higher on average than the stock system with the same ShurFlo & a lower CCHE scoop. The ATR cooler is less efficient (despite more surface area) and I don't think it slowed the coolant enough to really exchange heat optimally.

Re: Intercooling question

If you run alky then you negate those issues. Higher heat is at higher boost when you would have the alky on.

Some people run no IC at all and just use the alky. I didn't believe it myself until I sat in a truck and watched the temps drop by about 70 degrees when the alky came on.

You make a good point though - does a bigger IC need a bigger lower CCHE to cope? I suspect It will depend on a number of factors.

Higher ambient temps - yes, lower ambient temps no. But then it still depends on speed, power etc.

I have an ATR upper and a stock lower but alky and I think I'll be fine. The only concession is an electric fan over the lower so when parked or moving slowly, the lower gets some airflow.

Did you use the ATR lower piece or did you use the ATR upper?

All things the same, are you saying the stock upper IC is better than the ATR one?

I didn't even know there was an auxiliary lower...

I didn't even know there was an auxiliary lower...
Setup A) Stock upper IC, stock lower CCHE, 3/4" lines, ShurFlo pump, and scoop.
Setup B) Stock upper IC, ATR CCHE in front of radiator, 3/4" lines, and ShurFlo pump.

A had lower average temps than B.

Didn't try any other setups....didn't care enough to do so. I would think it obvious that the ATR upper is a better performing unit that the stock upper.
