Oil Temperature Issues

EventHorizoN · 07-25-2011, 12:42 PM

Hello Fellow Z Car owners,

Just recently I purchased the Z1 Motorsports 370Z Oil Cooler Kit.

The kit includes:
# 1x Setrab Oil Cooler Core (19 Row Standard; Additional sizes available)
# 1x Z1 -10 AN SS Oil Cooler Line Set (Optional protective sleeving available pre-installed)
# 1x Mocal Sandwich Adapter (Non-Thermostatic Standard; Optional Thermostatic model available)
# 1x Setrab Oil Cooler Lower Mount
# 1x Z1 Motorsports Oil Cooler Upper Mount
# 1x Z1 Motorsports 370Z Oil Cooler Install Hardware Kit
# 1x Z1 Motorsports 370Z Oil Cooler Installation Instructions
# 2x Setrab (-10 AN to 22mm Port) adapter fittings (Cooler)
# 2x Mocal (-10 AN to 22mm Port) adapter fittings (Sandwich adapter)
# 2x 13/16" Rubber Seal (Sandwich Adapter)

Some friends and I recently installed the same kit on my good friends 2010 370z. It works amazing on his car both on the street and on the track.

However, with mine its not the case. This past weekend I went to Streets of Willow and had some serious Oil Temp issues even with the Cooler installed. I know its working because I never have a rise above 180 degrees driving on the public roads. Yet, when I started driving on the track the temps jumped from 180 all the way to 260+ Thus making the car go into limp mode. Basically the car was running the same as when the Oil Cooler wasn't installed. Which makes no sense when my friends is working properly with heavy tracking.

Does anyone else have this problem, and if so what measures should I take to resolve this immediately! Thank you all in advance, and looking forward to hearing everyone's feedback!

Thank you!

Jason

You are in south cal, the 19R might be too small for you. Short shift by 500RPM, that will help lower the temperature for the short term.

Thanks for the quick response, it's much appreciated. I was just thinking the same thing, now I am seriously considering upgrading to the 25row core. A good friend of mine also asked me what my RPM range was while tracking. I think running the RPM's high will definitely increase the temperatures. I'm just hoping my car doesn't have a serious issue. We are going to Streets of Willow again this coming weekend, I really hope I don't run into the same problem again...

Hi Jason, hope u can get your problem solved. U might wanna change or get your car checked out before going to track. This weekend will be hotter than the night event.
This is Ricky btw.

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

Yea 19 is to small. The standard should be at least 24 25 row. I run a 24.

WWJD · 07-25-2011, 02:45 PM

^^There's another car running exact the same oil cooler that had no issue whatsoever. If 19 is too small, then how come the guy has the same cooler could run all day long without overheating?

What did Z1 tell you when you called them?

but were they running the same lap times? The harder you drive, the hotter the oil. Just like fuel starvation. Novices on stock tires get it around 1/2 tank or less, more advanced drivers on sticky tires get it before hitting 7/8 of a tank.

The op couldn't even run 4 laps straight. I don't think he ran hard enough to make the difference.
My guess is the oil cooler or hose or some hardware problems.
Also, I drove an Z with the same cooler set up for 20 min straight in 100+ F hot day. No issue.

Dustin@Z1 · 07-25-2011, 03:16 PM

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.

Was it one of our kits? I would be VERY impressed to hear about this! Are you sure it was a 6 series 19 row? Or was it a 9 series 19 row core?

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.

travisjb · 07-25-2011, 03:37 PM

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
