Is 19 row Oil Cooler too much for NA?
 

Hey folks, I’m considering purchasing the 19 row oil cooler kit from MAPerformance. By default the kit comes with a 13 row (I’m assuming targeting NA use) but my thinking is if I upgrade to the larger cooler I am future proofing for FI. Is this sound logic? Is it possible the 19 row cooler would be too large and prevent my engine oil from reaching optimum temps on the street? I’m assuming not because the sandwich plate is thermostatic, but wanted to reach out for better informed opinions.

Thermostatic plate prevents overcooling. Hammer down

With a thermostatic plate, my oil cooler still overcooked my oil in negative temps. I couldn't get my oil over 150 in highway driving

But you could without it? I've had cars refuse to warm up when it's stupid cold. And that was with no oil cooler. I suppose thermostatic plates seep 10% so that is more than zero

Without it was was hitting 180s-190s. With cardboard over it I was back in the 170s

I wouldn't have thought it would make such a big difference

I think because interstate driving is an extreme case. In traffic it probably would warm up, but we don't have much traffic in Vermont, especially not I winter

People don't work in the winter?

More rows nets less pressure drop. Get the big one and block off some for daily. Remove cover for track.

Dont more rows generate more pressure drop?

Of course they do ...... they just move slower ..... :D

I have the 19 row. No issues on or off track with the cooler. The coupler to the oil filter, area, however, leaks constantly so I've removed the cooler.

Opposite. More parallel paths is like having a fatter pipe.

Mhm. Doesn't going from a smaller pipe to a larger pipe reduce pressure?
