260 oil temp with 34 row cooler.... help!

With parallel coolers you have the same pressure drop compare to just one cooler. If you run them in series then you lose more oil pressure. Quite a few cars have parallel oil cooler design from factory actually!

So my point is valid, I was under the impression that forced induction are more prone to that, a friend has a brz with turbo, he have multiple maps and methanol, when we tried the conservative one (around 260whp) the oil temps was good for two or more laps, but when we switched to the aggressive one (I think 290 or 300whp), it reached the same level of temps within one lap. This lead me to try and see in my car, I know many try to get best power and leave the tune on the edge (I am a culprit as well), which isn't harmful in street as you don't redline the engine too much, but at track, it is a different story.


Yup, in my case I shift earlier unless there is a turn coming or I am trying to have the hotlap of my life, let's say around 7200 my sweet spot (before the little drop in power felt between 7200-7500), and my limiter set at 7700 I think, but yeah the pressure drop will be more felt on high rpms.

Most engines make the most power right at the edge of knock. When I was racing bikes. We used to say lean is mean. How lean could you get it without melting a hole in the pistons.

My redline is set at 8,000. I normally shift at 7,500. The extra 500 rpms I use for those moments when it's best not to up shift and then down shift for the corner coming up.
