Id just go with a 34 row and call it a day :)

I've been on the canyons on 90+ days and have not had any issues with oil temps.

It's odd that we both have the same oil cooler and I did not have the same issues at the track. I was running a little above 230-240 car felt great all day. Of course I don't have any bolt on mods.
BTW this is walter :)

The 6 series 19 row is very small in comparison to a 9 series 19 row. A 9 series 19 row will have a similar surface area as a 6 series 25 row oil cooler core.

Jason,
For a track'ed Z, we recommend atleast a 25 row core. In your case, given your local, I would even go so far as suggesting a 34 Row core if you plan on doing repeated track events. I hate that you had an issue with your Z.

Did you speak with anyone here at Z1 prior to you making your purchase? Let me know if you decide to upgrade to a larger core. I will do what I can to get you the best price shipped so that you can make the track this weekend. I have both 25 and 34 Row Cores instock and can ship today. Via standard ground service I can get you a core by Thursday/Friday without requiring any expedited shipping.

Dustin, you guys might think about offering a duct kit that directs airflow from the OEM front fascia to the core... using that setup, I've been able to run summer events in Arizona with only one setrab core... I'd guess it saved me ~20F. Mike B is also running this setup. Another thing you might consider is to reduce the gap between the oil cooler core and the radiator - I was told by some racing buds in AZ that a smaller gap there will make the leading core more efficient because it will help pull air through... no science to back that up, of course, so take it with a grain of salt

OP, you can mock up your own air flow duct/diverter to this core and try that as a next step... just go to ace hardware and buy some thin sheets of aluminum, cut to fit and mount up using rivets or frankly duct tape + velcro... the goal is to build a "box" leading up to the core so air has to go through the core and can't get around it

Did you guys install the cooler in the same location? Airflow can make a huge difference. What kind of oil were you running too? (Type/weight)

Do you have more or less miles?

The Setrab Brackets supplied in the kits can only be installed on the Driver's side of the core support. The combination of the A/C Dryer and OEM Power Steering Cooler hinders installation on that side unless you have a custom bracket made (..or relocate the factory PWS Cooler).

The question is, based on thoughts mentioned by TravisJB, is whether both cores are mounted close to the core support or not. I see that EventHorizon (Jason) mounted his close to the A/C core. I am not sure about GTKiller's install though.

GT can you chime in on this. I am curious to see if that may be another affecting variable.

If you have the thermostatic bypass I would check that it is operating correctly as it could be stuck in bypass mode. You can put an infrared thermometer on the cooler and the intake, outtake hoses and see what you're getting for temperatures there.
