so I went to an autox today and I was able to barrow one of the infrared camera's we have at work. I went with 2 members here on this board and took some pics of their tires as well.

*note that the labels (which tire is which) are not the same on all the pics. I didn't really keep track of the pics I was taking so I messed up a little when I was putting the pics together. so some are relabled cause its easier to move the text then the pics

here they are:







and I'm not sure on which tire is which side on this one, I just know the ones on the top are the front and the one on the bottom are the rears


here is a pic of first350's tires (he was on his in law's boxter)


and 2 of drivesolo's






and a pic of my car when we just got there

 

Did you happen to get a shot of your engine bay and/or your exhaust piping?

 

there werent that many people so the wait time in the pits was really short, i barely had enough time to take pics of the tires. i have the camera till monday though, i'll take some pics tomorrow after driving my car around for a bit

 

Thats pretty cool. Thanks for sharing.

 

technically speaking i suppose this could be semi-helpful. but on a coolness factor this is pretty far up there!!! thanks for sharing

 

Awesome! Pics of the brakes would have been cool too!

 

Thats pretty cool. Ever try catching a fart?

 

sweet pics.

 

Pretty cool. We can see considerable difference between the outside and inside of tires. I assume the “hot” areas are friction points: the area of the tire that takes the most abuse. Correct me if I am wrong.

 

The hottest area of the tire is the area where you have the most bending. Generally speaking, a tire that is over inflated will be hotter in the center. A tire that is under inflated will be hotter on the outsides of the tread. If one side of the tire is hotter than the other, it can indicate a problem with camber.

 

Thanks again for the thermal camera Warmilk - it was a lot of fun to see the temps all in 2 shot (I usuaully use a Harbor Freight infra-red meter, but it had broken last month)...this made it a whole bunch easier to see the differences.

*the end of the course had a hard left, followed by a few staggered gates...

**I think this was only warmilk's 2nd autoX, he's already super quick and it's fun to see how fast his times are dropping...I'm hoping he comes out to more events to give a good name to the Z!

 

yeah, it was my second event, thanks for the coaching peter, that really helped

although if i'm "super quick", whats that make you? extra super ultra ridiculously fast?

 

Thansk warmmilk for brining that out. That bit-of-kit is just awesome to have. It gave me really good insight as to the air pressuses I shuld be running. I never considered running the rears at less than stock PSI but it would seem that I can. Would love to see the result if we were to run a predominantly right hand course as well.

If you ever bring it out next time we can work out a situation where we can upll over immediately after we get off the course so we can get a better readings instead of letting them cool off as we roll back into grid.

 

Wicked Bro!

 

Temps seem kinda low...was it pretty cold out, or a very short course?

 

Not too cold. Ambient temp was about 60-65 and it was in the morning so the course was still heating up. We did have to roll all the way back to grid after completing our runs so the tires probably cooled off by a couple of degrees. Normally when we use a probe we have a designated area to pull off immedately after the exit of the course to measure temps. Warmmilk's gadget was a unexpected surprise that day, else we would have set that up.

 

Interesting pics - the temps are lower than I expected.

I see a set of Azenis, and RE-01R's. First set appears to be different front and rears but I can't figure them out....

 

the 1st set were warmilks...IIRC he was running different fronts than rears.

RE-01R --> first350 (on a '07 boxster)
615's --> Drivesolo ('07 350Z w/ nismo springs/shocks)

 

It could be very helpful for camber and alignment adjustments. I'm surprised that the top temperature listed is 90.
One would prefer that the inside, middle, and outside temperatures are all the same. So if the outside is gotter, you need more negative camber.

 

Very cool.

I had RE01Rs de-laminate the continuous center rib after a day of drifting, those photos give me a better understanding why since it was getting really hot!
