Pressure wise i get the same as what i had before i had a cooler. When i had a cooler without the hole in the sandwich plate i would see 70psi during vtec and that was with AN10 sized lines. I was running a 19 row cooler. The way i figure it at low RPM and low pump flows most of the oil will bypass the cooler through the hole. When the engine starts revving higher the increase oil flow will cause the hole to gradually become a restriction and push more through the cooler. Its the perfect solution, very little cooling whilst cruising around and then alot of cooling when pushing on and revving high.
Temperature wise my sender broke but it noticed a decent decrease in temperatures. I dont need that amount of cooler nowdays with only road driving.

I found something new ine the Setrab documentation:

And this is quite evident in fact: the shorter the row, the lwer the pressure drop.
So instead of gooing for a 235mm core length and 19 row, I am studying the possibility to go for a 115mm core length and more rows. The effect should be a low pressure drop, and quite reasonnable cooling.
115mm length and 25 row (estimated 15psi pressure loss) should approximately cool just like 235mm length and 13 row (near 60psi pressure drop estimaed !!)
