how do i take off the radiator airdam
#3
why do people always ask me why i want to disassemble my car...
anyway i took off the two front bolts, 3 bolts on the lower part on the inside, and 4 bolts all the way at the top on the inside, its like its clamped into place by something.

Now, I haven't removed one of these for a long time. Do I recall that all of the fasteners are plastic slip nuts on course studs? If you have studs protruding through the part on different plains (some vertical, some horizontal), it will hold the part on by shear physics. You have to bend the part to get it off one set of studs.
Seems to me I might remember that being the case here... in some foggy memory.

it is there to evenly draw air into the top portion of the radiator through the little slices in it, sort of trying to force the air along its even bend much like the hatchback glass from an aerodynamic purpose
i might, or may not, convert my top bumper portion to the "grilled" one to get more air to the radiator from the top
at which point the plastic cover will be an obstruction
plus like you said porsche designed it so it must be right, well, i want to see what it is that they think is right and compare it with what i think is right and try to logic out why their ideas or right are different from mine
after all, if all technologies were "right" we would all be driving identicaly designed cars
right?

Now...
Porsche is far from perfect. They do some dumb things. But, not many. Mechanicals they are good at. Interiors, ahhh; fair. Electrics? Awful! Aero stuff; they know their deal there.
The large area above and behind that crossmember behind the bumper is low pressure. The air forcing its way into the lower area will seek out the path of least resistance, which is into any low pressure areas. That plastic panel smooths the transition and I'd imagine keeps the air flowing more swisftly and smoothly as it rushes to fill that low pressure area. More air gets to more surface area of the radiator in a smoother fashion.
However, I also undestand your thinking regarding increased air intake.

here the caveat tho..
a) you have two huge fans sucking air in through the rad anyway and b) what does "smoother" air do for a radiator anyway?
or is the argument that if the air is smoother and better directed, then it could pack into the rad at a higher velocity, meaning more air, meaning greater cooling capacity
altho i fail to see the point once the car is up to speed at 100km/h ++

what if we install a thermostat that opens sooner?
and i wasnt aware that fans turned on so late on on a 944! its not like they rob crazy amounts of power.

and how am i insulting him? he's the only guy that bothered to give me insight on that mystical little plastic doohickey, then this clown comes and says somethign about dancing pigs.
i'm just asking questions, i'm not big on engines and aerodynamics, i'm more of a suspension tuning guy.
