Important engine "mod"

[icefighter35]

Can someone vissit this site and go to "motor-tuning" then select power booster, then tell me if that thing has any bussiness in the engine bay or if it is just some lame gadget which will most likely make the car slower and S**t. Anybody know of any other brand which makes the same type of booster?

from the looks of it its another one of those electric fans that you put in your intake, which will restrict air intake and, if it beaks, send pieces of plasic flying into your tb....no good...take the money youd spend on that and get just a regular cold air intake or a ram air and then be done with that end of your engines breathing.

LOL major BS, yeah its snake oil plus those guys need some 5th grade physics lessons.

to quote from them :

Copresses the Intake-Air
............
Cooles the Intake-Air
- cooled air burns more affectivly, because there is more oxygen in the Ai

compressing air is an exothermic reaction heating up the intake charge. Not that their POS fan could compress anything.

sorry, i agree with you ocmpletely except for the compressiong this. Once and For all... COMRESSING AIR IS NOT A CHEMICAL CHANGE. Fule burning in the cylender is an exothermic reaction, mechanically compressing air is not. there for it can not be clasified as a reaction. all you are doing is concentrating energy. this causes a tempature rise. here is how you can know if your compressor is doing anything as far as getting extra air into the cylenders.

STP (standard tempature and pressure for thoes of you who have no chemistry knowledge) is 273K or 0 degrees Celcius or 32degrees ferinheit. When it comes down to it PSI doesnt matter, displacement doesnt matter. its how much gas and oxygen you can get into the cylenders. lets say your intake is at 20degrees C before you compress it. and your engine is comsuming 3000 l/min of air. air is say 20%oxygen (i know its a tad more im making this simple on myself) . 600 l/min of oxygen.

20C=293K
293/273*22.4l= 24.0l is aprox. how many litres make up one Mole of oxygen at 20 degrees Celcius.
600/24=25.0Mol/min of oxygen is what your engine is consuming.
This is at a given 101kPa

lets double pressure to 202kPa (aprox. 1 atmosphere of boost) but lets say air tempature is a massive 100 degrees Celcius (212 Ferinheit)

100C=373K
373/273*22.4l= 30.6 litres to make one Mole of oxyen at 100 degrees Celcius
600/30.6=19.6 Mol/min of oxyen is what your engine is consuming. This alone will hurt power. that hot of an intake charge will make your engine run extremely hot and may cause knocking along with the fact that your engine will sence you are flowing a ton more of air (unless its one that also takes tempature into consideration) and will run your engine extremely rich and will prevent detonation but will also kill power. oxygen will be your mimiting factor instead of fule.

now 100C is very uncommon. you would have to be making a single T3 produce 1atmosphere of boost to a 350v8 for it to heat the air up that much.
600/30.6

Seriously you need to back off a bit and stop being so anal retentive. I said reaction not chemical reaction. Last time I checked the word "reaction" is not a term reserved exclusivelly for chemical reactions.

So what if i would've said:The procces of mechanical air compression will release heat and according to dictionary.com

Releasing heat: an exothermic reaction.

or if you word prefer another source Merriam Webster:

Main Entry: exo·ther·mic
Pronunciation: -mik
Function: adjective
Etymology: International Scientific Vocabulary
: characterized by or formed with evolution of heat

Main Entry: re·ac·tion
Pronunciation: rE-'ak-sh&n
Function: noun
1 a : the act or process or an instance of reacting

Lets place the two words into a phrase according to the two definitions:

When you compress a gass it will react(not in a chemical sense) by releasing heat.

Or

When you compress a gas it will react trough an exothermic reaction.

So according to two major sources my english was correct.

Of course exothermic reactions ussually refer to chemical reactions releasing heat. And yes I could have called it an exothermic phenomenon to avoid posible missunderstanding about chemical reactions, but there was no need for you to reply by schooling me like a 3 year old.

I did pursue quite a few science classes at university level even if my major did not require it and I would've hoped that you had enough knowledge of physics to understand that my username hints to a certain hobby of mine. So i do not apreciate being lectured due to some debatable semantics.

CBFryman gets owned

[nissanfanatic]

The heat created by compressing air is basically a series of enthalpies.

I wasnt being an ass. I just expect greater things from some one as educated as some of the people on this board. My chemistry teachers have taught me too correct. I am nit pickey about thoes things.
PS
That was far from scooling you like a 3 year old. i doubt of 80% of the people on AF could completely understand the concept of molar mass lead alone how it can be applied to forced induction and engines.

PSS
xyfalconsrock, did you even understand half of my equasion? no? then it seems you need to go back to HS chemistry.

CBFryman, please put in the effort to spell correctly. Consistantly incorrect spelling makes you look like a child and means 50% of people won't take you seriously, no matter what you're actually saying, and it is only 50% because the other 50% don't spell correctly themselves. I'm not implying you're dumb, you seem like a pretty intelligent guy, just giving you a tip.
At least spell fuel right, that one bugs me! Would you take car advice from someone who can't spell fuel correctly? I wouldn't...
Again, I don't mean to be a dick, it just annoys me and I'm sure it annoys others. You're not nearly as bad as most on this board, but I don't put in the effort to tell them because I could care less about what they say. Thanks...

[CBFryman]

Spelling is my fall out. I try, but sometimes i just get in too much of a rush to go back and read the post i just typed.

Thank god someone said it

Children, children, back to your corners....

[amanichen]

In the area of study known as thermodynamics, compressing air is referred to as a "process" not a reaction. Even in chemistry it's NOT a reaction, it's still a process.

CBFryman is right, Neutrino is wrong.

If you speak with a mechanical engineer (chemists don't design intake systems! ) you'll get laughed at if you refer to it as a reaction, becuase it's NOT.

[Hit_N_Run-player]

In an exothermic reaction, heat is given off correct? Compressing air does produce heat and i know that...Im not sure whos right here...

[CBFryman]

it doesnt mater, we understoon what he was saying, i was just making it more scientifically correct. but if you would like a chemitry lesson here it is:
Every chemical reaction can be classified as follows:

Exothermic-Realses Heat
Endo Thermic- absorbs heat

Decomposition-a compound decomposes into elements or smaller, less complex compounds
Synthesis-two or more elements or simple componds compine to make one or more comples compounds
Single Displacement-where one element or simple compond replaces another element or simple compound in a complex compound
Double Displacement-two or more complex compounts "trade" simple compounds or elements that mkae up their larger more complex compounds
Combustion-Most oftenly refered to as the combining of oxygen and a hydro carbon to form water and carbon dioxide along with other uncomplete compounds such as carbonmonoxide. but is more correctly defined as rapid oxidation
