Since we were all running together...have a pretty good idea what everyone went through...
Besides, the point is to show the variance based on different drivers....
I have about three different sets of same driver/different run data as well.

But again, thanks for all you've contributed to the forum. I know people appreciate it.

p.s. I also thought about heat shielding stock airboxes, so it would be nice to know if it makes sense :tiphat:

Personally, I'm a fan of oiled cotton media, but a lot of new synthetics have spec sheets that suggest they flow about as well.

Interestingly enough, AEM used to post evidence that their media outperformed paper and oiled cotton medias when literally caked with dirt. However, they also showed that it was inferior in flow to oiled media that was clean (go figure, they pulled the chart off their site -- I posted it here somewhere; probably in my gallery).

Anyway, on a N/A motor the difference will be pretty negligible in terms of power (maybe a bit more of a difference on a boosted engine), but I find the oiled media tends to do a better job of rejecting moisture in the air, and it seems to flow better when clean, so that's what I go with.

Additional heat shielding may or may not be worth it. It's pretty much unknown, but if metered air temps are close to ambient already when moving, then no.

It might reject some radiant heat sitting at idle, especially on an already blazing hot day, but I doubt the difference would be more than 1-2 whp because the air itself is still going to be heated up above ambient as it's drawn inside the bumper.

Won't hurt to experiment for sh!ts and grins, but really all this extra shielding is overkill for a DD -- The OEM airboxes proably work very well as they are and any further imporvements will yeild diminsihing returns.

This might be something to think about for drag racing, but if so, while your at it, why not mist the IM down to control even more heat?

Again, unless you can log what the ECU is seeing (or get a very good estimate with sets of thermistors) it's really hard to determine what effect if any extra shielding would have anyway.

You'd also have no solid proof that an entire run was made or that they had to slow down for half the time. It's near impossible to get a 100% clear run through the dragon when temps are above 40* unless you go at 4 am, so the likely hood that you got dozens of 100% clear runs with everyone driving almost identically is basically a load of crap.

Again, this is not an detailed scientific experiment, it is a collection of data points used to generate a general report on our brakes.
If you wish to break it down into a more exact experiment then yes, we would need to do similar runs at precise times and record every detail, but that would be ludicrous and just plain stupid for what the results are showing.

oh NOES an accidental space!!!

DarkZide 10-20-2011 01:15 PM

A couple of runs through by a halfway decent driver is plenty enough to know that the sport brakes have zero issues on the dragon. The speeds at which braking occur and the breaks in between braking keep it from fading.

Then he goes on to insult everyone by saying we are too dumb to want his "data". Yeah, thats who i'd trust for information.

Well, since he recorded the data when he owned the Z, has fairly good knowledge of cars (s2k, Z, Mustang, etc.) I would logically conclude he has the understanding of what to do in this instance. Also, from his posts I would see it as from an owner who is posting an unbiased review, might not fall within lines with your sugar-plum fairly tell land of how you feel with your Z so it of course aggravates you or looks as if he is 'insulting' Z owners.

Red__Zed 10-20-2011 01:17 PM

It not about fade. It's about how they heat, how the heat is distributed, how much winds up trapped in the caliper, etc. it's about knowing where to put your brake vents so thru actually help....

Its every single post he makes, essentially. Farthest from unbiased as it can get. I realize the Z isn't perfect and it has its downsides, but I don't need to see some tard in a mustang post on every single thread with a negative tone about it simply because he can't make his own choices and has to be "me too" about his cars.

because you need to duct brakes that aren't experiencing any fade :bowrofl:

The fact that you don't track doesn't mean no one does.

So you collect data from your car after driving on a public highway to determine how you should mod your car for the track since you track it so much?

This gets better and better :bowrofl::roflpuke2::rofl2:

Red__Zed 10-20-2011 01:26 PM

Thermodynamics don't change between the street and the track, curiously enough.

DarkZide 10-20-2011 01:28 PM

No but reliable retrieval of data does. You can't control what happens on the highway whereas you can at the track so the data would be immensely more accurate and relatable...you know...since you track your car so much anyway.

If it hasn't happend yet i expect to see some BS about how Z brakes get 1.368 degrees hotter than mustang brakes so we should all burn our cars to the ground and collect the insurance money.
