I just found your thread.

It is very insightful. For one I did not know that trick which you explained to crank the LS3 engine without pulling fuses.

I also learned that the Oil Temp Gauge does not provides an actual mesure of the temperature but instead gives out an “estimate” based on algorithms from the manufacturer.

While it is disappointing , it finally provided an explanation as to why I have encountered occasional discrepancies between the “gear/mechanical” temp gauge, the engine temp indicator and the oil temp gauge, the oil temp being the one that was in discrepancy with the others or making less sense to the driving I was doing at the time.

In my neck of the wood the temperatures are high, summer or winter, which as made me an advocate of any and all mods which improve engine/transmission and brakes cooling and a zealot of “heat mitigating practices”.
I often credit these two factors in allowing my PONTIAC FIREBIRD to reach 20 yrs this past march in pretty top shape.

So initially I would be all for doing this mod to my 2SS.

However, the mod you effected is not only challenging from an execution point of view but also is relatively expensive.

Hence, I would like to ask you, what was the main reason behind your decision to replace the OEM oil cooler?

Also I would like to ask if you did any sort of measurements before and after this mod and what were your results, in other words, would this mod be worth it for a regular Joe who does not autocrosses or drag races his LS3 but indulges in spirited driving sessions at least twice a month?

Your comments will be much, much appreciated.

Best regards,
