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

,

 

I plotted my last three laps using the datalog off of the Hondata KPro.  I guess I drive pretty consistently for the most part (though only driving 90% makes it easier to do).  The red L2 divergence is me slowing down to let someone pass down the front straight.  I only used third and fourth gears as I wasn’t pushing for time.  Looking at the data, it appears I could gain time by using second gear in the skidpad and turn 2 if I wanted to push.

 

A nice accessory which is great for the track is the 12V adapter for charging.  Therefore, there’s no fear of running out of juice.  The Replay comes with this little zip-up carrying case which I put in an extra mounting base, the lowboy mount, extra 3M double-sided tape, allen wrench (used for the clamp on the suction mount), micro SD card to USB adapter and the Replay stickers.  The Replay also comes with the little grey bag to protect the camera; it feels like an Oakley sunglass bag.  

It was another cold day at the track similar to my track day recently at Big Willow.  I don’t know if it even broke 50 degrees.  I figured it would be a good idea to take brake temps again with the ducts just as another data point.  So after doing one cool-down lap and pulling off the track, I hopped out of the car and took temperatures as quickly as I could.

The front rotors with the ducts attached measured about 200F on both sides.

 

The StopTech calipers measured about 140F-150F.

 

The rear rotors were much hotter at around 450F.

 

MotoIQ reader Tim in his S2000 was also at the track rocking a set of StopTech brakes. 

 

 

Tim recently installed the StopTech front BBK on his S2000 and this was his second track day on them.  Tim and I had traded a few emails related to the brakes and suspension setup and this is what he had to say about the StopTech brakes:

I was shocked at how good the brakes are. I bedded them in the day before and again the morning of the event.  OMG! They were so much better than the XP-12’s I’d been using.  Less initial bite, of course, but just strong from the moment my foot was on the pedal to the moment it came off.  Very even, very linear.  It made it easier to find a downshift rhythm.  And they were so consistent.  As good at the end of the session as at the beginning.  Man, I should have bought these years ago.  I am just speechless that a “street pad” could perform like that on the track. 

Tim tracks the heck out of his S2000 and would go through a set of track pads in 2-4 track days (depending on the track) with the stock brakes.  As this car is also his daily driver, he would swap out the pads before and after each event with the DD street pads.  Well, now with the StopTech BBK installed, there’s no more of that pad swapping.
