I think this needs to be tossed around a bit,I dont see the advantage of using the A/C to cool the intake charge,unless they have developed a new type of compressor dont you think it would be useless because of how much HP the compressor robs???

whats everyone eles opinion???

 

I don't think thats exactly how they work. It stores cold water to run through the intercooler increasing the density of the air which means more boost and power. Besides the A/C robs prob 10 hp at most and I am sure the A/C system because of the new water cooler feature is designed to be high effenciency low drag(no parasitic loss) to justify the design and development. Why would svt do it if it didnt make a difference?

 

The supercooler system only produces more power under FULL-THROTTLE application (~50 hp extra), and even then, it only produces more power for 35-45 SECONDS MAXIMUM (before the system is heat soaked again). The rest of the time, you would be losing power, because the A/C compressor would be running to cool down the stored liquid to roughly 30 degrees F.

Any supercooler system that is A/C based can not continuously cool the intake charge without taking away more power than it adds because of the efficiency losses inherent in A/C systems.

 

That makes some false assumptions.
First it is a concept

Second the description said that a dash mounted light would light up when the system was ready. If you assume that "ready" means that the A/C system is NOT cycling 100% to cool it then it doesnt take away power on an ongoing basis.

Third unless you are road racing or running one of the unlimited speed events like Ruslow 30 seconds of WOT will put you well over 130 mph. Which is more than enough of a jump in performance for most ANY performance enthusiast

Here is a fantasy scenario. You run the cooling system in the staging lanes at the track. When you near the front the ready light lights up. You turn the cooling system off to meet track requirements, tlo avouid driping on the track. You roll up do your burnout, which heats up the supercharger and intercooler.

Just before you light the last stage light you "enable" the system, you launch the truck with the advantage of the extra cooling for the 12 seconds it takes to get down the 1/4 mile. It should be worth a couple tenths at least ...

Just one interpretation of how the system might work

Isn't the a/c compressor turned 'off' at WOT? Might not be with the new system?

Btw, on my first, ever 1/4 mile run; I forgot and left the a/c on. Masterloggie was my 'co-pilot' and he got a good laugh out of it. Aren't co-pilots supposed to notice things like that and tell the 'pilot' to turn it off before the run?

I believe the compressor turns OFF at WOT. I know other cars do.

A system like this was designed for the Buick Grand Nationals ( www.coolflow.com ) which super-cools the I/C. It does this before you run and has enough capacity to last the full 1/4 mile as the compressor stops cycling at WOT.

 

Sounds like Doug must have done some heavty-duty thinking about this system between brews

 

When I read it I take it that the system runs all the time to keep the fluid at 30 degrees. The light on the dash lights up when the fluid is back down the 30 degrees and a WOT burst would take full advantage of it. If you disable the system in the staging lane and then reenable it as your doing the burnout, etc. then the AC is running to try to cool it back down. I don't think in that short time the system would be down to 30 degrees unless you could run it while in the staging lanes.

I wonder if you can enable, disable the system like this though. It better be an option.

 

Who cares? It's not like there isn't power to spare

 

Doug,

I was thinking that one could build a small shrouded tank to collect condensation. Might like to do this with my 99 as I like to have A/C at the Track except for about 12 sec.

The 99s have a WOT Switch that shuts off A/C, I'm not sure of the 00s-03s

While I was in Detroit getting my "Built Ford Tough tattoo " I had plenty of time to drink and ponder the super cooler ... LOL

ok, I'll bite
where did ya get it

 

Good interpretation of how the system might work; however, they are also just assumptions.

While the compressor may turn off at WOT (like it does now), and the system may turn turn off when the system is "ready", how long will the compressor remain off at system ready. How long can a tank of liquid cooled to 30 degrees F remain at 30 degrees F if the tank is in the engine compartment, even if it is insulated? One way or another, the A/C will be cycling whenever you are at part throttle and the system is not at "ready" (assuming it turns off when it is ready). I call that lost horsepower and worse gas mileage.

Also, how long does it take the system to cool back down? Say a person IS roadracing, and is in and out of WOT. Could this system keep up with those demands and still maintain any type of cooling effect? I don't know, but I doubt it. Yes, that is an assumption. But isn't this entire thread based on assumptions?

Is the idea neat? Yes. Does it cause power loss when cooling the liquid? Undoubtably.
