Innovate ot-2
Since our 370Z is daily driven and it is yet to reach the point of needing a gauge cluster, we needed a way to monitor on track temps.  Innovate's OT-2 was the perfect solution as it gave us a wireless interface with our iPhone that would be mounted safely to the windshield.  The OT-2 simply plugs in to the OBD-2 port and allows you to display real time data.

The Innovate Logworks-Mobile app syncs with the OT-2's and provides a very useful and easy to read gauge screen.  You have the option to monitor 3 parameters of your choice simultaneously and where you want them displayed.  The app also lets you record the data to review later via an easy to read interface.

 

For our morning baseline run, we went out with an ambient temp of 86 degrees.  Within two laps our water temp was hitting 227 degrees and climbing fast while our oil temp was racing over 240 degrees.  Clint Boisdeau, our test driver knew from his 370Z experience that limp mode, where the oil temp hits 275 degrees, was just a lap or two away so he aborted his session and brought her in. 

On a 370Z, a coolant temp of 240 means, start your cool down lap now, 260 degrees means, she's about to blow captain and 280 means she's done.  Clint reported that it took a whole lap for the car to cool from 227 degrees to under 212 and that the temps were climbing so fast he didn't think he could stay another lap at speed.

 

With us surfing the overheating zone on the track, we pulled the car into the pits to add some much needed cooling.  On the 370Z changing the radiator is a pretty involved job so be sure to read through your Factory Service Manual thoroughly.  First the bumper fascia has to come off.
 

A whole bunch of push pin plastic clips had to be removed at the top of the bumper to get it off.

We carefully removed the bumper and the top part of the fiber reinforced plastic core support.

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
