Installing the largest possible street racing radiator for your 370Z - part 2 FINAL

Did you see any impact to maximum oil temps with this? I keep thinking the water temp gage is rigged so it's non-linear. It seams like it gets up to temp too quick and then it's more rock solid than it should be. I would think keeping the engine block temp more stable would help keep the oil temps down.

First, you are right, the water temperature meter gauge is NOT linear. Notice that the final dot ( near the middle ) where the temp lit up is when engine temp>= 158F.

The larger radiator does help the oil temp. This is most noticeable when you program the fan so that it turns on sooner than the factory setting at 213F ( I did it at 195F ). It lowers the oil temp down to 5F less than before.

With all of that said, I still recommend a 25 row oil cooler or better since this VVEL engine is running brutally hot and a larger radiator simply will NOT be sufficient to bring the oil temp down to the level that I wanted.

Good luck
