Ecoboost filter directly on turbo?

[Table Lamp]

Quick question this is really a weird subject but would it even be possible to put just a K&N filter directly on the turbo and what would happen with your ecoboost would it even crank up and can you even drive with it on there?

You'd be eliminating the MAS and the car won't run without it.
Also, even if it would, you'd be pulling hot air from the engine compartment which wouldn't help at all.

you cant do it. physically it can be done sure. So its more you shouldn't do it. I know some turbo turbo builds out there do it. But its unrealistic on this platform

The ecoboost doesn't have a Mass Airflow Sensor, just a temperature sensor for the inlet. It will start and run with the air cleaner duct removed from the turbo.......

Really? How does it determine air flow then?

I'm not familiar with EBs, but if there's no MAF then it probably runs a speed density tune mainly off of the MAP sensor.

It is a speed density system that use IAT, MAP, RPM, TPS to determine fuel and spark timing.

Thanks for that info. I did a bit of research on speed density tuning and it seems it relies primarily on the MAP and IAT to calculate the air density in the intake. I know that is an extremely simplistic take. But if the IAT is giving skewed readings it's got to adversely affect how the engine runs.
So, while it might run with the filter directly on the turbo I can't imagine it would be good for it.

Yes, even just the 4 sensors I listed is being simplistic, it uses far more inputs than those to map the tuning for our motors for sure. You are correct that if the IAT is reading much higher than ambient temp it will skew the tuning map table being utilized by the PCM.

So, with filter directly on turbo inlet and IAT not in fresh intake air stream flow but rather under hood high temps it will not run well and possibly cause damage as well.

Plenty of centrifugal guys run a filter directly on the blower or a turbo guard. It's just fine. Doesn't slow them down at the track.

What does the TPS report?

What does the TPS report?

TPS reports the desired throttle position requested by the drivers foot and the actual throttle position of the electronically controlled throttle body. In today's electronically controlled throttles you will never get too full WOT, best you will ever get is about 90% plus or minus a few %.

Before fly by wire (electronic) it just reported the actual throttle position of the throttle blade that the driver was commanding with their right foot.

Yes, but that's a very specific application and I'm sure the tune is designed for that. Quite a bit of difference from removing the intake plumbing and dislocating the IAT on a stock car.
The OP never said anything about any other mods. To me the implication was simply remove everything and plug a filter onto the turbo. If there are other things done or planned, they weren't stated.

Thanks. I should have known that but I had TPM stuck in my head b/c one of my other cars has a problem with it. And I wanted to make the Office Space joke.

First we need to have 6 or 7 meetings to talk about it..can you schedule a couple meetings so we can schedule the 7 other meetings..May need to add a couple just to go over the cover sheet.
