Do you regret choosing your power adder?

Surprising you dont know

2006 mini cooper s, i own one so i would know, i believe its an eaton supercharger with a top mount air to air intercooler

Okay, so get that to work on the Mustang. There's no room under the hood for that shit and you would need a massive air to air intercooler to do the same job.

My car uses water for space reasons

No, it's because it couldn't be air cooled. AIR SUCKS AS A HEAT TRANSFER MEDIUM

One more PD / a2a example and we can consider it a common setup. Post up data logs of that setup so we can quickly dismiss.

Check this monstrosity out! 45ci of supercharger!

"a big enough air cooler is just as good if not better than water"

Ummmmm, No.

Air2Water FTW !!!!!!

And yet turbos and centri setups use air to air? Whats your point?

its almost like you admit pd makes more heat so they NEED the water cooling?

That exists due to packaging constraints.

Because every one here needs a 4500hp setup and follow that for everything

People fit front mounted air coolers, and retrofitting a custom water cooler is completely possible and done here

they use air because of cost and weight, which for a mini, 100lbs of water cooled stuff is a huge % of the cars weight just to get a little better cooling

Water is better. Again, why OEM's like BMW, Audi, and Corvette use them now on their turbo setups.

Vortech/Procharger don't want to make you install an A2W intercooler plus a heat exchanger. There's only so much room under the hood of the car when you're not re-designing things like the intake manfiold. And as I showed you, even ESS uses A2W with their custom intake on theM3 because that's what they needed to do on that platform.

And that's why all the big boys go A2W when they hit a certain power level.

A good time to just dip from this debate

especially as this thread was meant for reasoning between setups, not claiming pd is best and refusing any comments of other setups other than “weight” and “cost” when we talk about a measily 100lbs max and a few thousand dollars between setups rated for the same power level

The fast mini coopers throw that tiny Heaton in the garbage and go turbo

We're talking about fucking Mini Coopers now. Ugh.

How could you even get an air to air system working with a PD supercharger?

That's exactly the point, you are fixed with a water cooler because of the constraints of the pd arrangement. That's why you need a super efficient and heavier method of cooling it down and only a few companies have managed to make it a success, whipple 3.0 and all the top mounted vertical flow pd setups.

Do you understand now what I mean when I say "I chose a setup that didn't have the problem to begin with?" Holy moly this is tiring!!!

Yes it works, does it mean it's the best way, not really!!!!

What s/c makes more power throughout the whole powerband?

Also if you go to the drag strip, most of the big power centrifugal cars are running air to water as wel

• Specific heat capacity (Cp ) air at 0°C and 1 bara: 1.006 kJ/kgK = 0.24028 Btu(IT)/(lbm °F) or kcal/(kg K)
• Specific heat capacity (Cv ) air at 0°C and 1 bara: 0.7171 kJ/kgK = 0.17128 Btu(IT)/(lbm °F) or kcal/(kg K)
• Thermal conductivity at 0°C and 1 bara: 24.35 mW/(m K) = 0.02094 kcal(IT)/(h m K) = 0.01407 Btu(IT)/(h ft °F)

• Specific heat (Cp ) water (at 15°C/60°F): 4.187 kJ/kgK = 1.001 Btu(IT)/(lbm °F) or kcal/(kg K)

This is why people use water. The 'to-air' heat shedding of the cold side is ~same since the size of the radiator is ~same and made of the same materials and fin structure etc.

Water is simply a buffer that can absorb 4x as many J or btu than air for a unit of volume, till it reaches saturation and is then gated by the ability of the cold side to shed the heat. But on a 10 second pull nobody cares that it takes 2 hours to cool the water system down before it's next run. It absorbed the heat out fo the intake charge and thats what matters.
