The street oil cooler is what we would like to recommend for 99% of the owner's of the 370Z's. The race oil cooler will be a bit overkill for the majority of people and just won't be necessary. The street oil cooler has been proven to work very well and offer a big reduction in temperatures. Even on the track the street cooler is working very well. We just wanted to see the temperatures get a little bit lower while on the race track.

So is there a dis-advantage to running the race cooler on the street? I was just driving in traffic yesterday (it was hot, bout 98deg) and was not even close to driving aggressive, my oil temp was fluctuating from 240 - 250. Even on a cool day, my average oil temp is 220. If the race cooler has a 40 degree reduction, would still be at 180 right? Also, I plan on running a supercharger, I have a feeling this will kick up temperatures a bit. Is running the car with too low an oil temp bad, and what is considered too low for this car?
I notice that the car runs really good and feels way more responsive when first starting up in the morning, but as soon as it starts creeping into the 200 range it starts to feel sluggish.

Judging by your list of modifications in your sig. I'm assuming you do not currently have our street oil cooler? I would suggest starting with this. For street use I think you would have a hard time pushing the temperatures beyond a safe point with the street cooler. The race cooler might be a bit much.

When we say that the race cooler might be a bit much we mean that in two ways: 1) financially speaking-At the end of the day the race cooler is substantially more expensive. We know this but the core is substantially larger so the cost is going to be more. I firmly believe in the philosophy that if you don't need to spend the money, why spend it? If you don't plan on driving your car hard on the race track then the street cooler will be fine for you. 2) Streetability- With the race oil cooler in particular you will want to have a thermostatic plate installed. We will have this option soon, we're just trying to find a source so that we can be competitively priced. As it stands right now you can pick up a thermostatic plate for pretty cheap from sources like Amazon.

It is possible to have your oil run too cold. 180-200 degrees is pretty much optimum and realistically 180 is on the cool side.

Thanks for the info and recommendations Kyle

That can't be the Nissan people told me 220-260 is optimal and perfectly fine(true story)

This may be too obvious to mention, but when you first start it up in the morning, it will run rich. This would make it feel more responsive. The ECU will obviously take that down after a few minutes of run time (it's usually only a minute or two for me at around 50-60 degrees ambient).

If the effect you're talking about is different and lasts all the way up to 190 degree oil temp, then please disregard this post
