Cool SC via AC
I mentioned to a car guru that I may convert my Stillen SC from air to liquid cooling over to air to air. He said I shouldn't and I should keep the liquid cooling and use the air conditioner.
Has anyone considered this or heard of this? He had to go so he couldnt elaborate on it but said he would stop by next week to talk to me about it. /Z/ |

The part I don't get as I haven't really read up on it much, is the parasitic loss from running the AC as well. Superchargers already take what like 80hp just to turn it? I suppose as long as the gains are more than the loss then it's all good. It really is something I should educate myself on more, especially with a pending installation just around the corner! :)

A guru that doesn't know crap. What a surprise.

Another so called entitled member expecting to be spoon fed info without actually doing any work to find a answer. lol
Waste of my time to spoon feed lazy members Thanks for the link ChaseZ, it was a interesting read :tiphat: |
There's a reason you haven't heard much of these and never seen one. Because they are gimmicky, complex and will still never perform like a proper Air cooled charge. It might help a little when sitting at a stop sign for several minutes waiting for your temps to drop but it just can't keep up with the amount of heat it needs to cool.
You would be way better off just setting up a sprayer and hitting your ic with meth water or nos. While still a band -aid fix, These actually have some merit. Do you really think adding this will gain 100whp and 100wtq like the a2a kit is capable of? Not a $700 gamble I would put my money on. |
Thanks ChaseZ and TopGunZ for providing some constructive and worth while comments. I admit I do not know a lot about engines but I do know enough to put in my own super charger...and how can a lazy person actually install a super charger? By spending 100's of hours reading internet websites, forums, blogs, you tube video, talking with mechanics, and asking questions to the manufacturer...oh but wait I'm lazy...I better go to be now.

Maybe I'm missing something but a car A/C doesn't remove heat very quickly and it seems to me that it will be overloaded once air flow gets much above what the HVAC fan puts out. Add in compressor drive losses and I'm guessing you will have a net loss at the crank. But that's just my guess - it would be interesting to hear from someone who knows thermodynamics and could run some numbers.
|
Yes, I can't imagine it could net you much if anything. I hate driving with the AC on as I can feel the drop in power and the drop in fuel mileage. But apparently I'm just a lazy member expecting Zat Zuma to do all the work ;-P
Oh well, this week I will talk to a coworker that has experimented with such a system. /Z/ |
Ford made an ac cooled charge as a prototype but it was just a "hit" would give around 50hp for a short period of time then the liquid had to be cooled down again.
It's something that works, drag racers use ice boxes, same concept but it's not a full time usage thing like air2air |
imazman it wasn't really directed at you but if you take offense to the comment, maybe your guilty and you know it!
A lot of members expect me to give them all the answers without researching themselves. If I answer one, there is always 10 more questions after that. It almost seems that some members expect you to provide the answer to every question they have. (their is no reward for thinking of the questions) That's why I no longer help members and if I need a answer to a question I can usually find the answer with a little work, reading and figure it out. If not, I can innovate and engineer a answer. Plus, I know that I'm not the only one who feels this way. |
Why do we have a forum? It is to help share ideas, knowledge and yes, questions. I have seen bitter members who have been on here too long and they are like the cranky old man who hates kids because he forgot what is like to be one scenario.
To those members, go pick up a hobby you don't know anything about and remember...dont ask any questions. |
*slow clap*

Ooookay, back on topic, this is the first I've ever heard of this idea going mainstream, always was in the back of my mind before and I'm curious now.
For those complaining it would sap power, there was a standalone 12V option, a '2kw' system... but a 2kw compressor on a 12V system is an enourmous drain (166A+) if my math is right? Surely I'm missing something. Cheers, MoulaZ |

But, yeah, it takes about 167A at 12V to produce 2kW. P = I * E = 166.6A * 12V = 2kW |
Even without the parasitic loss from this...its still a gimmicky system. People probably have bought it and tell their buddies how awesome it is without collecting any data.
Honestly, this reminds me of the electric supercharger you put in your intake for $29.99 off of ebay except it costs $700..so it HAS to be good! Again, i can see it maybe making sense on the drag strip...maybe. Where you sit in line, blast AC all over your aftercooler coolant, drop it below ambiant, turn your AC off and make a pull. Then its all over before the system heat soaks again. But in real world, street, track, this reeks of cheeze. Even on the strip you would be far better off dumping ice in the tank as stated before. Basically, in order for this to be effective, the AC on a constant basis would have to out perform the under hood temps created from the engine plus the heat created from the supercharger, which are like 200+ degrees to begin. |
Top is correct. After logging many runs during my tune, I could see just how rapid the intake air temps would drop as soon as the boost was gone which means I still get the same amount of air density that I did on the first pull. A2A is simple and effective.
Thanks again TopgunZ for developing the A2A kit. |

First off I've been racing and tinkering/experimenting with cars since 1980 (I know I'm old) and one the first to have a VQ in 2003. Had to learn about the platform with research and was one of the early adopters for some of the things you enjoy from the vendors today. I use to post all sorts of information (deleted most of it) but it only got me more questions via PM. Sometimes up to 20 a day. I found it was members to cheap to pay a guru for the info and used the info to beat a vendor for a cheaper cost on a project. But still, I worked with the vendors and helped bring new products to market. I figure if their too cheap to buy a membership to this forum, they have no right to my intellectual property and deserve to be singled out and chastised for it. Besides, I'm not selling anything, besides used parts; therefore I have no obligation to any answer questions except to the for parts. Plus, everything I do, innovate, or invent is on my dime and therefore my property. I have no sponsors that I have to promote. I may commission the occasional vendor to build something for me and share it with them but not non-paying members of this forum. I help the local members, quite a bit and I'm out of racing/building/advising gurus, on cars/trucks for the most part. I have no ego that requires me to post and I'm enjoying my retirement :tiphat: This matter is closed and for those cheap non-members looking for free info FU ... buy a membership and read lots. Read lots and lots........the info is out there and probably been done before. |
The heat tables on the cooling required to cool the intake air volume/velocity is too large for the air conditioning unit in the vehicle. This was attempted on the Hemi's in 09 and failed miserably. It's too small to make a difference to IAT's , except at idle. Best bang for the buck is spraying the intercooler with water, during a run. But, eventually, the intercooler will be coated with calcium and loose efficiency and your no further ahead.
The biggest A2A intercooler possible, with Meth injection, is one long term solution, that makes sense and may last. |
What does this system do when the AC shuts off when you go full throttle? All modern cars do that, so if this is run off the clutched AC compressor, then it ONLY works when the car is NOT at full throttle. Additionally, when it's only on when the AC compressor is engaged, then the drop in temp is probably only going to make up for the extra drag on the motor for turning the AC compressor.
