Poll - GTA GB for oil cooler

wheee!

ummm... mine comes with one. The reality is, the plate is never completely closed to prevent thermal shock to the engine. So it does take a while for the oil to fully come up to operating temp even with a sandwich plate that is thermostatically operated.

This is correct. The fact that you have an extra quart of oil in the cooler and lines also adds to the time it takes for the oil to come up to normal operating temperature. Like I said, I have a Z1 kit with 34 row cooler and for the street and my location, it is over kill hence I've have had to make use of a blocking plate to increase the temperature. Without it, even at 25C it will not get past 80C. The kit is too efficient for the street IMO, but would be great should it be tracked I assume given the cooling efficiency.

Whoops didn't read you were using Stillen kit lol.. sorry my bad.

Then would you think a 25-row would be OK for both DD and light tracking? Or would the 19-row be enough?
By calculations, blocking off a 34-row with a 3" plate is approximately the height of a 25-row. So would that mean 25-row would be fine for DD?

I've never tracked my Roadster but I remembered when I did my initial investigation, a Stillen rep recommend the 19 row for my climate. By deduction, a 25 rows would be recommended for 'DD and light tracking'. I only went my route because I am not sure if I will FI or how it will respond to tracking sessions, so it was safer to buy more than I needed now and make due with the blocking plate.

On that note, I have had some rethinking about how to manage the temperature to exact degree using a more sophisticated method than a blocking plate at the cooler . If you were to install a ball valve between the cooler and the engine, you can regulate exact amount of oil to the cooler. This will necessitate a bypass line to form a loop when the valve is in a close position. The down side is additional cost for the valve, bypass line and 2 t-fittings. The upside is you can regulate your oil flow to exact rate to the cooler.
