Z1 Motorsports 370Z Oil Cooler Kit

crwallace1 · 11-29-2011, 05:42 PM

Based on Dustin's comment it is possible that the mocal thermo plate is in fact working properly. I blocked my cooler (will post that in DIY) and observed a freeway oil temp of ~210f suggesting a 40-50 degree temp delta across the cooler. So when the oil temp is just rising off the 140 peg it is likely that the inlet (and sandwich plate outlet) temp is 180, as it should be. However if the unblocked freeway outlet temp is 160 that is still the temp of the oil heading into the engine for lubrication, which may still be a bit too cool.

Thanks, my oil cooler(s) arrived today. Will search around for a block plate.

At what temp does the mfg rate the sandwich plate to open?

Here are a couple, pretty much the same with additional mods and more in detail on the second link.

DIY: Oil Cooler Cover

DIY: Oil Cooler Block Off Plate

Is there a thermostatic plate that opens around 200 or 210? That seams like it might make a bit of difference for the temps entering the block?

I do agree with you and we have suggested this in the past to many of our customers and forum members here on the370z. Owners of Z/G's living in cooler climates or in the winter with ANY oil cooler should consider blocking off the front of the core during the cooler times of the year. This method is used widely by racing teams to further regulate oil temps.

Race teams will block off individual rows of the oil coolers during test and tune to "fine tune" oil temps depending on the track conditions, humidity and driving style.

I did my first weekend after upgrading from the mods hack cooler to the Z1 34 row lat weekend. Outside temp was in the 70s and oil temp never went above 225! I used to see it in the 260-275 range.

Are the readings at the track or normal DD?

Mocal does make a higher temp thermostat, but it is a remote mount style. This is a completely different setup when compared to the standard thermostatic sandwich plate that we currently use.

The current opening temp of the thermostatic sandwich plate we sell is 180* degrees F. This means, at 180* the bypass valve fully closes and directs 100% of the oil into the oil cooler core.

To build a custom Remote mount thermostatic sandwich plate with a higher temp. thermostat, it would increase the base kit price atelast $100 if not more. This is due to the fact that there would be double the total amount of fittings, 4 lines instead of 2, the requirement of a custom mounting bracket for the thermostat and a slight revision to the instruction manual.

I have had customer's express interest in the kit before, and would be willing develop it. We simply did not go this route due to to the added complexity and cost, which would have priced well out of the range of comparable kits. We wanted to make sure that we are competitive in every aspect....inlcuding price.

If you are a DIY type person, I can source the parts necessary to convert your existing -10 AN lines to accept the Remote Mount Thermostat. The catch will be the fact that you will need to cut your existing lines into two pieces, install new fittings and mount the thermostat. The sounds somewhat easy in writing, but assembling SS lines can be a pain in the neck!

Good to know, so with the false readings on the dash gauge, what would be the difference in actual temp and gauge reading? So if the gauge is reading 160 then what is the actual leaving the engine block?

track. I couldnt say what it runs on the street, as I don't drive it there, but I think coming home from the track last time it was under 200

ZForce · 12-03-2011, 12:26 AM

Good to know Mike, thanks for the feedback, appreciate it.

ZForce · 12-03-2011, 12:28 AM

crwallace1, be interested in seeing your block plate DIY.

Dustin@Z1 · 12-05-2011, 11:37 AM

Thank you ZForce for linking these two threads. I greatly appreciate the help. The overall design of the block off plate can be simple and easily created.

ZForce · 12-05-2011, 08:17 PM

No problem Dustin

I love this forum!! Here is an inexpensive mod that is functional. Rep to the OP's of the two DIY's for the block off plate.
