Project S2000: Part 17 – Testing Temps and Tools (Replay Camera and IR Pyrometer)

,

So the two S2000s with big brake kits and front brake ducting exhibited much cooler front rotors than rears.  The Evo on the other hand had much hotter front rotors than rear.  They showed an even larger temperature difference between front and rear compared to Project 370Z.  I would say the Evo could definitely use some front cooling ducts.
I’d never measured my tire temperatures before.  Tire temperature information can be very useful in determining proper tire pressures and alignment settings.
The right rear was warmer on the inside and getting cooler to the outside.  This is consistent with running negative camber.
The left rear.  Not much heat was generated in the rear tires.
Even less heat was generated in the right front tire.  It looks like I probably could have used a little more tire pressure as the middle was colder than the outer edges.
The left front was hotter on the outside and cooler on the inside.  Running Streets of Willow in the clockwise direction beats up the left front pretty good due to the long right handers.  Running more negative camber on the left front would help in this case.
There were a pair of C6 Vettes in my run group and they were having no luck getting heat into their tires.  One guy was only able to get to around 120F in the fronts and only 80F on the rears!  An Ariel Atom in my group on Hoosiers had it even worse.  He had a supercharged K20 and with no heat in the tires; any application of the throttle caused the rears to spin.  I have to say the Nitto NT01s are very good in cold weather.  Their grip level was only slightly diminished even with the low tire temperatures.  They really only needed one lap to get up to temperature (well, as high as they were going to get).
A buddy of mine from StopTech brought out his track toy.  FYI, that’s Project Evo X MR next to it… I hear it has arisen from the shadows and has goodies to be installed. 
There’s a StopTech Trophy kit on the track toy of course.
Here’s the oil cooler doing its thing as shown with the peak recall feature on the ARK Design MFD2.  With these cold air temperatures and the Earl’s Temp-A-Cure oil cooler’s ability to keep the oil this cool, I just use the standard fill 10w-30.  Don’t pay attention to the 96C coolant temperature as it actually only hit 90C on the track (thanks to the Koyo radiator!).  It hit 96C as I got stuck in stopped traffic on the 405, and then Santa Monica Blvd, and then Lincoln, and then PCH…
