ok, i just had to put this in to prove a point.
some say that people run 11'* and 12'* with a bonneville and dont run 17 psi of boost. well that is true but as for the numbers, they better look again. here is a page from high performance pontiac with a bio and numbers of digital kens car. he is the designer and builder of the zzp mini afc 1.0 and 2.0 versions..
once you read this, you will see that in fact he isnt running 17 psi of boost, he is running 24 psi and in a GTP that they converted from a roots SC to a paxton novi.
here is the artical and everyone can read just how much R&D, money, and company backing to get a car in to those numbers without nitrous.

Ok.... now you're just arguing, you called an M62 a turbo even, it'* not a turbo at all. It'* a revolutionary new thing called a Supercharger... Belt driven, you should check it out sometime!

A turbocharger is an exhaust driven device. A supercharger is belt driven, they both have VERY different tendencies, and both drive very different. Both push air into the engine, but it is very different. Quit arguing for the sake or arguement. I don't try to be a bad guy but a lot of people are sick of it from a couple people. If you're gonna be "to the letter" then be that way with what you say, no one likes a hypocrite.

i for one am sick of the fighting. i know what i have and what my boost gauge reads at WOT.
myself, i turn wrenches for a living and dont have a full time job sitting in physics class trying to make it to high school graduation so i can drive daddy'* car to the prom this year.
also if you happen to look at my mods, i have done just about as much as i can do other than building an air to water intercooler for my m 62. so in the spring , im going to use a zex system set up with a rpm window switch.
this will be my last post on the issue, well concerning dbtk2, im just trying to make my car run faster. and since there are very few performance parts for us guys with a series 1 motor, we have to do the R&D ourselves. and at our own expense.
im sorry guys for for even bringing this topic up.

Great, you know what I hate pullin out the soapbox
No..Jeff, don't be sorry. I'm very tempted to go erase all the bickering and bullsh!tting that I read in this Force Induction thread.
Keep working on your car and keep sharing the results. Please don't let bickering and pandering stop you from posting. I and the majority of this forum have learned much from your R&D. And you are very correct, there is not alot available for Series I engines so this is good information.
The next person that wants to argue in this thread will be sternly warned. Let the man post....keep it constructive or hit the road..literally.
[soapbox off]

I never meant for this to turn into an argument, and I am sorry that it did. The points that I were trying to make were valid and constructive IMO, and I am sorry if they weren't in others opinions.

I've been told that compressing air reduces its ability to hold water in the vapor state, but I'm not too sure about that. If it'* true, then its not inconceiveable that air density at some specific pressure and temperature is sensitive to the process it has undergone.
Water in air? Welcome to the wonderful world of non-reactive "pseudo" two component systems; your first approximation is to ignore the air entirely, and look only at the partial density (or partial pressure) of the water vapor --- once it reaches the dew point density (or vapor pressure) for the temperature you're operating at, it condenses. The system isn't ideal, meaning there are odd corrections, but this gets you into the 10% ballpark.
Remember, density is a state of function, not path.
(Thanks Physics Forum)
That being said, there is a displacement effect that occurs when you put more water in the air. You not only have an "equalibrium" effect in temperature, but also density and pressure, thus raising the volumetric density and efficiency of a defined volume. Now we start to go back to the basic caveman research. Fuel + oxygen + ignition = fire. The more of any of the first two of these components you have, the hotter and bigger the fire. So the denser the oxygen or fuel, bigger bang, more ponies.
Oh, and as Physics say, cooling air DOES compress it. Cooling ANYTHING causes the molecules to come closer together, which happens to be the definition of "compress". How do you think superconductivity works? By cooling the temp to less and less Kelvin. It works with matter AND anti-matter, thus it'* universal.
Was that more than 2 cents???
