The stock radiator is really buried in the core support so the support had to come off.  This makes the install way more involved than typical.  It took us a couple of hours, but luckily we came prepared  and had brought all the necessary tools (and then some) to the track.  The washer reservoir supplied with our AEM intake and stock power steering cooler had to be moved out of the way as well.  

 

 
Finally we have the radiator and A/C compressor assembly exposed and ready to remove.  Before the environmental nuts get up in arms about how we evacuated the system, we took our Z in to the professionals the day before the event. 

 

 
Time to drain the coolant. 

 

 
Here you can see that the CSF radiator is over twice as thick as the stock part.

I noticed you replaced your coolant with the "standard" green antifreeze. There is much debate as to whether or not you should put the green stuff in a system originally designed for orange/red/pink coolant. What are your thoughts on this?

Great to see some local tracks represented here.

Any chance PTCC will make an appearance at Willow Springs in the future?

Clint - All props to wrenching so hardcore on all your stuff! Will you be looking at the newer Focus for a new time attack platform, out of curiosity? I hear that ST is a good start :-)

I'm actually amazed that someone took the effort to change the radiator at the track. It provides more consistent data for testing even though the track temp rose.
However, I'm unimpressed with the oil lines Nissan uses for that oil cooler. It doesn't seem like a clean install for a "factory" sponsored part. I'm also not a fan of red/blue AN fittings. Just my opinion. I'm sure they work great. There are several Vegas residents that get limp mode on their 370Z after less than 30 minutes of light street driving and an oil cooler is a must.

how you want to run the Lines is really up to you for the oil cooler, so i mean if you wanted a more "tucked" or "clean" install of the lines that is your choice.

@Jeff, I changed my radiator at the track on Project S2k :) You can read all about it!

I have a similar question to Dusty's. What about using a pink coolant in a system originally designed for the green stuff? I know you can't mix the two (usually).

i personally am unaware of the difference in function between different color coolants. Hopefully someone chimes in from the staff with a little more insight
