best oil coolers ? help

Thermostatic kits are not always necessary. They are there to make sure your oil gets up to temp quickly, as it can be just as bad if your oil is too cold vs. too hot. With certain applications a Tstat is the only way to accomplish that, but not for the 370's.

Slow warm up time is a common problem for oil cooler kits that use long horizontal rows. It takes the oil a lot longer to circulate back to the engine and in turn takes a lot longer for the oil to heat up. The oil is also physically in the core for a longer period of time which slows down the warm up process significantly as well.

Unfortunately the 370z's need a hefty amount of oil cooling, which in turn means big cores. Before we built our kit, we tried 3 different aftermarket kits (19row, 25row, 34row) and with the 25 and 34 we experienced slow warm up, and with all three we were unable to get more than 2-3 laps before we hit limp mode. But that doesn't mean you need a thermostatic kit. The Setrab 72 row core we use in our kit, utilizes vertical rows, which completely eliminates the issues that cause the slow/limited warm up. The oil isn't in the core as long and it circulates much faster which get's the car up to temp very quickly. We have kits on customer cars in very cold areas and we have had great feedback on warm up times even in extreme cold conditions.

The way we think about it is that it works better to utilize a core that works with the car (if possible), instead of trying to band-aid a core that doesn't quite work properly for the application. It also eliminates the need for additional parts and as most have experianced, with more parts, there's more things that can go wrong. That problem is also heavily exacerbated when you are going to the track as well.

So that's why we developed our kit for the people who want a tested reliable solution, that works great both on the track and on the street.

So you mean to tell me my 34 row cooler from Setrab takes longer to warm up than your 72 row? Im not too sure on that one. I think you guys are using a different sandwich plate adapter. I looked at your kit and it looks really clean +1. But not too sure on the vertical vs horizontal flow. Also what degree is your thermo adapter set for?

Casey@AEperformance

Definitely not what I am saying, haha, and we don't use a thermo adaptor. I am saying that our kit warms up quickly as well, but without the aid of a thermo adaptor. It doesn't really matter which is faster, it only matters that your oil gets up to temp quickly enough to not adversely effect your motor.

In your case, your car get's up to temp quickly enough and your oil temps stay cool on your canyon runs, so your kit works for you.

In our case, our car went into limp mode before we could turn three laps on the track with a 34 row core. So we needed something more and that's why we developed our kit. It get's up to temp quickly enough and it lasts all day on the track, which is what we needed.

It works about 90% good enough for me. If the ambient temp is low enough it keeps everything in check, but on hot days in the midday sun I'm still hitting 280 after 10 minutes of driving on track.
