The 1000w fan has been around for years. Available on M240/340/440 with cooling package and on G series M cars as standard. It bolts right in to the Supra.

Hah yea, the modern Bosch ECU's are pretty awesome. My past life I tuned Evos and those ECU's are like sticks and twine compared. There are some traction control tables where you can fine tune ignition timing retard when TC kicks in. It's set very aggressive OEM. There are also some tables that...

Yes, that way it runs the same setpoint no matter the elevation. So 90 - ambient = gauge. So where I live at almost sea level, ambient pressure is 14.5, 90psi absolute = 75.5psi gauge.

They are designed to fail to high pressure instead of low so the odds are in our favor. :)

It's all in the tune, you can tune the OEM turbo to feel like a lazy big turbo too. This is actually a key part of tuning larger turbos (and even the oem turbo) on the stock fuel system with ethanol blends. You have to ramp the boost in in the low/mid range to avoid maxing out the oem HPFP...

I haven't yet, but I am a sample of one. ;) I do have a 2020 though so it's probably just a matter of when, even if I didn't increase oil pressure. If/when my pump fails, I will probably swap it with a ZTK pump. There are two tables that set the max/min oil pressure that will trigger an error...

It shouldn't really fluctuate much. PID is there for it to hit target, just like boost control. There is also an offset table that is used to up pressure for Vanos depending on load and rpm. OEM it's set to increase oil pressure around 3000-4500rpm When I defined the Oil Pressure Setpoint I...

You are correct, pre brake coding, it's hard to even get heat into the rear brake pads.

Yes, the PID tables. I haven't defined them yet but they are there. I can put some hours in this week. Oil pressure setpoint: (5500hpa = 79psi absolute) Oil Pressure PID tables:

The oil pump is electronically tied into the DME. It has pressure set point tables and full PID control.

If you plan on running only 20psi I would look to the pure 650. Spool wise, a lot of it can be in the tune. A good tuner can make even the OEM turbo laggy if wanted. Also, protip… don’t listen to anything Mr. Crustacean the Mansplainer says. He just posts weird made up shit that he doesn’t even...

No. It helps run cylinder temps run cooler but not by enough to notice it significantly in coolant or oil temps. What do you have your coolant temp targets set to?

Back end flash. It’s a weird term for having the ability to flash the DME but still using a piggyback for some odd asinine reason.

He does/did that all the time. At least he didn't get all defensive and say "why should I share my hard work with you?!?!" like he did when I challenged him on some other asinine statement he made. "why should I share my hard work with you?!?!" with him is code for: "I don't actually know what...

Wait, you mean to say Mr. Crustacea the Mansplainer was sharing incorrect information again? Say it ain't so. Hope things go smoothly for you @sanasupra!

Pure 800 shouldn't be breaking a sweat around 500whp with an eth mix. The log screenshot posted above of my Supra is a Pure 800 making over 600whp.

Yea true, I alwasy forget to list that. @Islindur has a hood vent too though. I upped my oil pressure, which ALL track supras should do. Even 100% stock fuel system Supras have VANOS deviation in the upper RPM when making more power than stock with the OEM oil pressure setpoints. OEM is approx...

Cylinder temps do make some difference to oil/coolant since it's in the block but not a TON. What does your intake setup look like currently? airbox to turbo inlet. What weight oil do you currently run? (for once not a funny question)

General rule of thumb is larger turbo at the same boost will create less heat than a smaller turbo. Of course it's a balance as larger turbo can spool slower and not be as responsive. However, you can negate a bunch of that with proper VANOs and PID tuning.

Since this topic stated from seeing oil temps from my track video... Here is actual data from the track, 11 laps in at Lime Rock park. Charge air gets wayyyy more toasty than theory would have you think. Pure800, 27-28psi peak out the top. Wagner manifold (shedding 249F of charge temp at this...
