[QUOTE=markk;6745092]You are not even close to a competitive event doing a track day, trust me I've done both.

I think you are dreaming if you think a beginner can push anywhere near a racer. Not ever 5/10ths[/QUOTE

Let's not argue for the sake of it, My point is that a closed thermostat makes no difference to the gearbox than one without a cooler other than some weight.

A beginner will change gear more times, over Rev a car more often ask more of an engine than an expert driver and over drive a car, that is what I am saying.

I have done both too and I have seen many a poor driver with a race licence.
