Seriously?

You have a point and you might well be right, but I am not certain if the difference is as big as people seem to think. I have done laps at 200F/220F/240F and 260F. My datalogger shows no noticeable difference in acceleration between any of the laps with corner exit at the same speed. The difference between them is so small that I am not sure if it does anything on the road. A few HP, I would buy in, but the car isn't going from 330HP to 230HP.

I mean I wish I didn't have to spend $700 on a new oil cooler, but I think Nissan would take care of most of the complains by putting in a oil pressure gauge instead of temperature.

I think it has something to do with the fact that the VVEL system is operated through the use of the oil. When Modshack did his oil cooler write-up back in 2009, he seemed to allude to this when summing up the research he did.

I don't Modshack linked backed to the actual research items he found but they may be in that thread somewhere.

She stares into my soul...

You are probably right swapping the oil temp guage for an oil pressure gauge.

I think the temp difference is more pronounced down low because you have less power available down there. Like 6th gear at 2k RPM's where you would only have maybe 200hp available instead of the full 332hp. I definitely agree it is not losing some 100hp due to oil temp though. We would all be driving lemons then.

As far as the $700 oil cooler, I think I am going to Modshack's route and just build my own except go ahead and get stainless lines and use a 34 row unit instead of the 24 he used.
