Great write up. I do live in central PA so I don't think I'll be running one personally. I will be doing a coolant flush and fill with some Mishimoto Liquid Chill coolant when I have the chance to leave my car overnight to get it done. Hopefully the better coolant mix of 50/50 as opposed to what I believe is a 60/40 coolant/water mix that comes OE has the desired result of keeping cool under load.Oil coolers, cool in flight and very little setting still. This is where the engine requires a cooler and stable operating temperature. If you're in a northern climate state and not tracking/racing or severely utilizing the car, you don't need one. However, southwestern states will benefit from its use.
I say it again; Heat soak, is a major issue for performance engines. The longer it's utilized the hotter the engine becomes and retains the heat. This heat affects horsepower output. To keep the engine cooler and to remove the heat produced, one of the things it needs is cooler oil and coolant temps. This reduces heat soak. The hotter it is ambiently, the hotter the engine will becomes.
The higher the horsepower, the higher the mean or baseline operating temperatures. So, as you begin to improve on horsepower and performance, engine temps will rise accordingly,as you're push it beyond it's designed capacity. So one of the immediate benefits of an oil cooler is, reduced sump and engine operating temps. If the oil is cooler the coolant system isn't over overworking.
Oil viscosity remains stable and provides better lubrication. Better lubrication, provides better durability and longevity. When you add horsepower, you add more stress to the engine. So, you have to help the engine do its job more efficiently
Is adding an oil cooler going to help your confidence in the car and the engine or is it simply relative to use. Do you want the added capability or not. You are never going to regret it's installation, especially when you already have it in hand. What you will do later as part of human nature depicts is; take a loss for a new part in hand. Periodically, mull over the monetary loss and lack of capability. Then later decide due to additional modifications, it best to add one.Case in point; my wife loves sports cars but she putts around with them most of the time, which is fine. She knows the cars capability and its always there for use. Having that capability and know it's available can be helpful in necessary situations. Same with engine capabilities.
Your environment almost demands one, considering the regular speeds you can and do drive at. Along with altitudes which cause greater variations in hotter operating temps. Think "Thermal Bypass Valve" also.I'm really tempted on that oil cooler since summer temps have been around 35-40C (~100F) and will rise in the future, then again temps in winter can get as low as -15C (~5F)...
^Thermal bypass in-line valves are available at specific temp settings. So, it not difficult to bypass the cooler when it's not needed.I'll be using it with the 200 degree release spring so at least it'll be at close to warm enough temp year round
Made sure I got that with my kit!The Mishimoto Thermostatic Oil Sandwich Plate is a lightweight, high-flow sandwich plate built from 6061 aluminum. The built-in thermostat prevents oil flow to the cooler until the engine oil reaches activating temperature, allowing for both a faster warmwww.mishimoto.com.au
