Just struck me as odd. I definately prefer someone with a sense of humor mixed with technical knowledge. Welcome aboard!!
I would recomend that you use the search function for topics about your companies products and how many feel about them.

 

naw dont change it... you will fade in better
lol

its good to know your trying to improve alpines reputation... it will take some work and you might be getting a call from me regarding the turbo setup

welcome to the board

You guys think hdk will do the same? naw....
lol

 

Hey guys I do not know jack about turbo's , superchargers....ect ect ect......but How come no one tries to utilize their airconditioning to cool down such hot parts

 

hey ballrub......like the name by the way. how much do your s/c kits run for, and are they intercooled??

 

hey tibb junky.. PM him for that kind of information...
Your putting him in an awkard situation (forum rules)

Thanx ballrub for trying to help us CURRENT customers

smile.gif

 

my apologies..... didn't realize it.

 

I have corresponded with ballrub via email regarding problems I am experiencing and am just now waiting for a solution from ballrub after some information he needs to acquire.

I will post up the transition of all of this as it progresses.
According to ballrub the next email correspondance should be in a week or so.

I am hoping to have more positive results regarding the s/c problems on my car the next time I post.

And am hoping that ballrubs 25 years of experience will be helpful in turning around the current image and situation regarding Alpine and its products.

Gotta love his timing.
Oh! and welcome to the forums ballrub! happy.gif

 

Air conditioning systems are about 30-35% efficient in most cases. This means that you use about 3 times the energy that you remove in the form of heat. Since you're generating energy by using heat(combustion), and the 4-stroke internal combustion engine is about 38% efficient under ideal conditions, and the engine is driving the air conditioner--you're using about 9 times as much energy as you're removing to produce the cooling effect. So running the air conditioning actually causes a net increase in heat produced.

 

The problem is the heat produced by the supercharger itself (the heat produced by compressing air)(thermodynamics).

The supercharger does not cause the engine to run "hot", rather it is the tempature of the pressurised intake air that is the problem. With an intake manifold mounted roots type postive displacemnt supercharger, intercooling is simply not an option. So some method of cooling the external supercharger (minimally effictive) or cooling the pressurised air charge needs to be found. Cooling the "outside" casing of the supercharger is not going to do a whole lot. Dropping the casing temp from 150 degrees to say 70 degrees might net you 1 or 2 degrees drop in air temp internally. The process of pressurizing the air is what creates the heat, so by cooling the casing you are just treating the "symptom" not the "problem".

A dual fan/lower temp theromostat would lower the temp of the engine coolant, and the oil a tad. An oil cooler setup would lower the oil temp, and the coolant a tad, but neither really solves the problem of high intake charge air temps.

To the best of my knowledge, your only option is too cool the air via some form of injection.

You can add a water injector to cool the air, but the water displaces air (if there is a bit of water, air can't be occupying the same space), so you loose some of the benefit. Hopefully the decrease in intake charge tempature will offset the air displaced by water.

You can add methenol/water injection, but since methenol is combustable, the Unichip would have to be retuned to lower the fuel from the 5 injectors. If you ever run out of meth/water, you're in for a world of hurt.

Nitrous injection would cool the intake air charge, and any displaced air would be replaced by N20, which has more oxygen that ambient air. The problem, it is cost prohibitive to try to run this setup 24x7, and the fueling requirements would be tricky.

You could TRY to fabricate some form of intercooler, but given the limited space between the supercharger and the intake ports, it would have to be water/air. It would also have to be a VERY unique design. It would have to serve as both intake runner, and intercooler. Intercoolers work best with small passages with lots of surface area to allow for heat trasfer. Intake runners work with large passages and minimal surface area to keep drag do a minimum. Somewhow combining the two in the maybe 12" of limited space between the supercharger and intake ports is nearly impossible. Given an unlimited budget, you could probably make a workable system, but for us "do it yourselfers"...forgetaboutit.

Just trying to live up to my sig line...

 

Ballrub, welcome to the boards and personally I'd like to learn a lot from you, I'm pretty new to the world of tuning, and there's lots that I still would like to learn, especially from one with your knowledge and experience.

Please post in the Off-Topic forum the answer to this Q: Why the hell did ppl call you BALLRUB in the first place man!?
