About the only thing the IR gun will tell you is if one rotor is way hotter than another rotor. Which is useful for telling when the caliper brackets lock up on crap mustang brakes.

Wow...what do you want then? I full scientific study? No offense, but we take what results we can get from owners, and use the data in a relative method to apply to an average for all. I doubt Red is saying his results represent 99.9% of everything, but what it does represent is solid data which no one else has generated with as much accuracy as you can achieve in a field study.

Then why trust his "data"? He doesn't own a Z and ever since he sold the one he did have he's had an overly negative connotation towards everything Z related on this board under the guise of "helping out". 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 am glad you have offered up and implemented better solutions, and all you data so far has been invaluable!

I think you seriously underestimate the amount of lab time I have.

4 points on the rotor is more than enough to get a good idea of temp and distribution. A series of 10 or so cars, with temps taken after several runs provided pretty solid data--certainly more rigorous than anything else that has been provided.
I did find that at the end of the dragon, temps were pretty constant throughout the rotor. There wasn't much hot spotting, mostly due to it being a longer run without any hard braking zones.
More telling was the diff temps, but I'll spare you the results

I think you seriously overestimate yourself. As long as different drivers were making those runs the data is totally junk, as everyones driving habits are different. 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.

am having problems finding an emoticon for this threads progress

Red__Zed · 10-20-2011, 01:10 PM

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.

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.

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....

DarkZide · 10-20-2011, 01:20 PM

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

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