2019 sti build

[james-30]

So I have a 2019 STI that I'm building. For now I'm going full bolt on as there really isn't much info out there on how much power the refreshed pistons can take. I'll go stage 2 IAG closed deck later. For now my goal is a reliable 400awhp on stock internals. Even if the car can safely take 400+ im shutting things down at 400 as there is no reason to trash the stock block. All parts are still rolling in and I have yet to tare into my car. My question is am I forgetting anything?

planning to upgrade suspension?
if so ill buy your stock suspension

Yes, I already have most all parts for my suspension as well. Still need coil overs and rear adjustable lower arms. Replacing all bushings with super pro and also I have a DDS driveshaft.

E85?
I almost went with FP black.
How many miles are on your 450hp build?

I was recommended fp rep by mike Adkins - mtuned. Trust him . JR says fp blue or black.

About 1k on it so far. I do drive the car hard cuz I have a daily

Would recommend going fmic. Intake temps are always -14 below ambient

Intake temp 63. Ambient 76, okay -13

Intake manifold temp and intake temps are what you want to compare. The ambient temp on the dash isn't using the same intake sensor and will always read lower than intake temp.

Congratulations, you have inaccurate sensors.

Try and fight physics, I'm sure it'll work out great.

These are the same sensors used to measure before and after ***129335;***127997;****9794;***65039;

As far as I am concerned this is accurate. If someone can help educate me then I am open to that.

An air to air intercooler cannot cool charge air to a temperature colder than ambient, its just not possible. The absolute best you can hope for with an air to air intercooler is to have charge air temps be equal to the ambient?temp. Just think about it, say your charge air is 110*F and ambient temps are 73*. How does 73* air cool the charge air below 73*? It cant.

I have to disagree as well, you will never get below ambient with an air-air intercooler. It's just not possible, the laws of thermodynamics say so.

You can expect the ambient temp to be higher if you were sitting and the sensor is heat soaked (the ambient temp sensor is in the bumper/grill area where it gets a lot of heat from the radiator etc and not much direct airflow to quickly cool it). But if you are constantly seeing lower intake temp vs ambient, one of your sensors are off.

Front mounts are great though. I saw about 10 degrees over ambient with the factory top mount and now i am 3-4 degrees over ambient with the front mount.

What about FMIC with 50/50 water/alcohol spraying on the IC? I know that's not his case, but with high humidity levels, shouldn't that create the same effect? Evaporating anything on metal surface should drop temps below ambient, no?

It can definitely drop it a bit below ambient momentarily, but it would be hard to maintain it below ambient during a hard run. The benefit to a spray will be seen mostly when the cooler cant maintain it's maximum efficiency.

As far as what liquid, it's all about making that liquid change to a gas as fast as possible as that's what will use the most energy (heat absorption). So any liquid that evaporates faster than water should be more effective (a lot of people use windshield washer fluid because of it's methanol content). There are limitations - Most people see no cooling benefit running over 50% methanol/alcohol, while the safety risk skyrockets above those levels.

Dude, for one, isn't that 'intake temp' on your AP the Air Box temp right at your filter anyway?
Not the actual intake manifold temp post intercooler?

Or do the 19's have different placed sensors than my 16?

and yeah, it cools it below ambient? nice!

The sensors are the same. Lmao. Sensor is upstream of the turbo and IC still.

It doesn't cool below ambient lmao.
Enthalpy, how does it work?

[greygonzalez]

Let me add to the intake temps.... that’s at cruising of course. Idle or at a stop if not below ambient ***129315;

[james-30]

okay enough abt air to air intercoolers.

How hard it installing all four plugs? Also turbo install. Ive never done a turbo before.

[james-30]

So I'm thinking abt swaping my Cobb intake out for the 18-19 AEM intake. Looking like the map sensor is now inside the box on the aem and filter looks much larger. Anyone have any feed back on this?

MAF*. You probably wont see any discernable difference in performance.

The AEM flows more than the Cobb. Whether it's worth it or not is debatable. I never liked the noisy Cobb box, though the design is efficient.

The Cobb is loud for sure. My tuner told me the AEM doesn't flow as good as Cobb. I cretin he hasn't seen the re design for the 18-19 sti.

I have MAF logs that show the AEM flows more than the cobb on my 17 sti. My tuner thought the same thing.... He even sent me the log and I had to point out to him that the flow was higher on the AEM.

Again, not significant but ....
