There needed to be an air seal between the hood and the air intake. That much gap was allowing the wind to blow around the air intake instead of building any kind of pressure. There should have been some kind of a gasket between the two, maybe a foam donut or something. If you brought the blue intake hose through the hood, you could seal around that with some duct tape.
so you took a turbo charged motor and made it naturally aspirated... The scoop on the subi is for the intercooler. To cool it cus its a top mount. To get better performance place a front mounted intercooler and use the hood scoop into the turbo inlet. Also .5 bsr is around 7 psi so a few holes in the wastegate line will increase boost pressure (old school way lol)
You can't put the MAF in turbulent airflow like that, not to mention the housing you put it in was much larger than what it was tuned for (big no-no). The engine was running so poorly because it was running really, really lean. Really, you would have been better off just leaving it out.
The turbo being disconnected, the ECM is still using the base turbo FUEL MAP, so it's going to run super rich... at least at WOT, it's still going to try to correct... He mentioning it at around
There is high-pressure air just above the bonnet and low pressure air 5 - 10 cm above the bonnet, you need high pressure air. So the stock scoop is in the high-pressure range and the make shift scoop is way above the high pressure into low pressure which is why its not boosting, the big scoop will have turbulent air inside and not only that it will have big drag also. If you had lots of smaller scoops on the bonnet leading into the hole it will make for better ram air. This is why fast cars have scoops on the sides and top of the car to get the high pressure air running along the body.
"We disabled the turbo, now the air has a massive restriction sucking air in the blocked intake, the ECU probably went into limp home mode, but hey guys on the 4th run if I'm learning to modulate the pedal, I can feel it picking up."
Put a vacuum on the exhaust. Reverse super charging?

I figured out what is wrong. The thumbnail shows a red hood scoop. But the tests were done without the racing red paint.
I'm pretty sure the engine went into limp mode after the first run.
The subaru scoop is for the air air intercooler... 😂

It looks like someone crashed into a snowblower with that thing on the front end... :P
Thanks BMI Russian for always doing an awesome job and making it possible for us to enjoy good content!
The intake hose should have an airtight connection onto the scoop and the scoop should be sealed at the seams.
the scoop needs to be sealed together with the intake, or you loose most of the pressure
?…so…the hope is that the ram air puts more air into the engine then the turbo? This would have been a better test on a naturally aspirated car.

Have you guys ever tried filling car tires with water instead of air?
Removing the turbo was your mistake
The ram only works at higher speeds. Cant do proper testing with it on lower speeds.
i like that your channel is working on other cars besides Ladas now. It is a much needed refresher
I did this to my tiny engine, can confirm the effect kicks in at 80km/h, wasn't struggling uphill anymore.
