Eventuri Prototype GR86 Intake 

probably going to be the same as every other gr86 taking off the charcoal filter. the results from doing that seem to be anywhere from 5-8hp, and you get that with pretty much any intake, or, again just by removing the charcoal filter. It's very placebo as far as actually feeling the performance.

Agreed, though I’m not even sure those ramps are doing much to redirect airflow. Question if there is any ‘ram’ effect at all. Let’s not forget the stock intake is incredibly well optimised, and will be very hard to beat.

ram air intakes are designed to use the car's speed to increase static pressure. So typical designs use a scoop with a wide opening that tapers into the intake manifold. But yea you're still better off just going force induction at that point cause how much more air are you really getting in there. I do think the FA24 can make decent use of a ram intakes due to being a high compression motor though

@@ninchalla_creates Thats the marketing talking. As soon as that air hits the filter it gets slowed right back down. Its a giant obstruction directly in its path, no matter how free flowing it claims to be. At that point you will get whatever volume of air the engine is capable of taking in. Thats it. There is no additional volume of air making its way into the cylinders at any point. Drawing the cooler air in from down below may be of some benefit though.

@@boost331 Ah that's a fair point. I failed to take that into account. I guess also to your point the engine can't compress air more than what's given since there isn't any positive or induced pressure on the intake manifold. So even if there was no filter what would actually happen is a localized build of static pressure that doesn't make it to the engine to begin with

Not if it’s being pulled from the engine bay

@@ez8308 I don’t thin you know too much about cars. Every car now pulls air from outside.

@@ez8308 I don’t think you realize what a cold air intake is. 90% of all car manufacturers design it to pull air from the outside now.

This design does not look like it was airflow tested either, just looking at it, I can tell that at speed it will create some turbulent air inside and those scoops wont be very effective since you need a closed system to hold air as it picks it up. Plus you should NEVER block airflow to the radiator. As-is these engines run hot on the stock radiator. To anyone wondering, the stock intake with the charcoal filter delete and a basic K&N filter will get you 95% of the best intake design out there. The only thing better would be to route the air from the front of the car, ideally from a headlight or a newly created hole. And the design would be similar to an F1 design in which the air enters into a larger chamber of air where it can be somewhat "compressed"(usually like 0.1 psi) but that has to be designed perfect or it can rob you of power at higher speeds instead.

@@jrod1577 I really liked the Perrin cai. I miss the cai from my crx and integra type r where the cai routed down down near the ground behind the bumper
