The setup of a car has a lot to do with how much you overheat the engine. If someone runs 200 treadwear tires, has stock power, no aero, no race pads, I would say that the car isn't going to overheat quickly---if at all. Adding performance parts like high grip tires, aggressive brakes, aero, etc......these things make a car overheat far more quickly. Also, weather plays a big part. On a 50º day, a car runs great and can go forever. On a 109º day, the same car puts in lousy times and can overheat quickly. The AIM data indicates that there is less build up of heat per lap with the oil diverter. I'll take that! Let's put it this way-----is anyone else posting any kind of truly actionable data that shows that some other solution is better? If someone is willing to share a great cooling solution and post real data, I'm happy to listen. Getting a few more laps in an HPDE is all you need to get through the 20 minutes. If you were getting 3-4 laps and then overheating, and then you can get another 3-4 laps----let's say the laps are around 2 minutes, and that's 7 hot laps on average, plus a warm up and cool down.....you're over 18 minutes. Sounds like a job well done! And really, isn't pretty much ANY passive cooling solution like a bigger cooler or an oil diverter just trying to prolong the amount of time it takes for the heat to set in?----Trying to make it so that you simply stop driving the car before the heat is a session-ending problem? Now, something like meth injection is different. But running meth is a solid commitment, and you better not run out! It's also worth mentioning that no car can run at 100% MAX pace doing laps around a road course-style track for 20 minutes, and it's not because of the engine----it's because of the tires. The tires need a break regardless of what level of motorsport you play in. And the heavier the car, the worse it is. So, regardless of what an engine is capable of, the tires will always be a limitation. Anyway, the oil diverter is only $80, but it takes 4-5 hours of labor to install. So it's not the cheapest mod if you have to pay for labor. (My shop installed it). Was it worth it? For me it was, but I don't think it was magical.

have you re-use the spring or you have fitted the diverter valve without spring?

Thanks, but I was looking for the discrption from Epic. The links are well known. ;-)
Yesterday I had a look at my oil filter housing and found the thermostat. So super easy to remove this. |

Were you able to replace diverter valve without removing oil filter housing?
