Maybe a Supra GTS 2023 MT, Kia Stonic GT, Mazda CX5 GT SP
Fooling around with wheel colours again today. I think I prefer the more subtle silver. Then again maybe not, lol.

pipe will exit the rear-side. We were playing with the idea of opening up the diffuser and routing there and even running a blown diffuser setup... but ultimately didn't want to over complicate the setup and went with a rear-side exit exhaust.

Absolutely love the color.

My stock version:

It wasn’t today, but this week, car came back from shop after some installs and tune. Pure900, do88 manifold, 1050 injectors, BMR catch can, BMS intake, motiv reflex+, flex tune. My shop/tuner took these photos

Not a Corvette.
Couple of things to note:

Coolant temperatures are very stable on heavy load in general and compared to stock. I have the Wagner Tuning Manifold. This was a really good purchase.
The manifold has zero to do with coolant temps. That is a completely different cooling circuit.

Yes. But do they actually work or are they just pure marketing?
They do, but do you need one? Ideally, oil is above 212F/100C to boil off the condensation in the system. Ideally ideally, you maintain a temperature around 230F. These values are higher than many people expect. On my last car, it was a real struggle to get oil above 190 and all these goofballs were running around installing giant oil coolers anyways. That oil needed to be HOTTER, not colder. They should've used a tstat to control flow into the cooler, and they probably didn't need one at all.

So, if your oil is cookin' at 260F+, yeah, an oil cooler will help and is a good idea. But if you're streeting the car and seeing temps like 230, that's great. Keep it and do nothing.

Had a Helmholtz resonator fabricated to combat drone from ~1900 to ~2300 RPM - seems to do the trick too.

What single exit is that?

Yup. There's a huge misconception that oil needs to be as cold as possible. Just like brake pads, there is a temperature operating range that they should be at.

My winter beater/track rat is an N54 335i and last summer I did a plethora of cooling upgrades so that it would survive track sessions without going into limp mode. The N54 runs even hotter than B58, so managing temps was a struggle. I finally did enough to keep temps in check, but this winter in the Mid-Atlantic has been brutal with temps not exceeding 40F in past few months.

Until I can swap the thermostat to a 212F unit, I'm having to resort to cardboard in front of cooling stacks to reduce airflow so that I could get my temps into a more desirable range. Even drove without turning on the heat in single digit temps just to keep the heat isolated to the engine 😅

Undestood. But I live in Miami and on Jan 23 the oil temps peaked and stayed at 260F. In January.

While the Supra's cooling system is much better than my N54, yes, I think it could benefit from an oil cooler. Just adding that there is a such thing as running stuff too cool.

260F isnt that bad honestly if it was stable. Most good engine oil will be stable against shearing at that temp.

Are you using 50/50 mix of coolant?
Running higher percentage of coolant to distilled water will lower temps (I ran 90% water to 10% coolant during summer, then switched to 30/70 during winter).
