And not even a mention of how small you need, or what space available.
I've used filters from Greddy and Burger Motorsports, both very compact, although not as tiny as that K&N.
I'd say both flow ok, no restrictions measured in terms of pressure at the filter. However the Greddy's didnt filter for **** ( although they'd be a million times better than some piece of **** screen )
Burgers havent been on enough miles to get a good opinion on filtration.

Hey sorry I was working when I posted it so got in a hurry with the details.. but I got about 3 inches from turbo intake to the core support.. I could trim it a bit but ofcourse would rather have something that fits..along as it doesn’t rob a bunch of power

3" is pretty tight, not a lot of real options there.
Burger's smallest is 3.75", I used their 4.5" one, the Greddy I used would be around 4-4.5" too.

I would be cautious about that K&N getting pulled into the turbo if it sits too close and there is no support structure behind it

It keeps the intake of my turbo clean which is what I really care about on the street and it only takes a few seconds to pop off to be race ready lol.

I ran a cobra elbow and a big cone filter pointing down on the front of my s480 because i had constraints at the front of the turbo also. At 770hp i dynoed with the filter and elbow on and off. No real difference was found. On the street i tried it on and off. It seemed to spool slower with it on but looking at logs it was exactly the same. If you can do something similiar id look at siicone intakes they sell a good cobra elbow. As a warning dont remove the rib in the middle of the elbow. It keeps the elbow from colapsing against the face of the turbo. Just an idea.
Wow, that's surprising to me. I once had a mild centri supercharged engine and it was very sensitive to restrictions on the inlet side. Just changing the inlet pipe to supercharger yielded +3 psi and +70 RWHP. Straight up efficiency gains and nothing else.
Maybe the answer is your filters somehow aren't as restrictive as one might think when looking at the small size?
Not boosted, but I had to use a big *** filter with my n/a 427. Ended up buying twice because the first 'big' filter wasn't big enough.

That’s what I’m saying. You don’t see air filters on serious track cars. If they werent a restriction, don’t you think they would run them to save their turbo/engine from debris?

While my dumbass is over here running no filter and daily driving on the street.
To be fair, I fabricated a pretty protective shield around my head unit. Nothing is getting in from the bottom, period. But I am still running a risk. Eventually I'l make a custom filter.

A large air filter is less restriction than a small air filter. The more surface area the less restriction.

"A large filter with lots of surface area robs power. This little flat filter will rob tons of power"
He's saying that *of course* this small filter will be a power-killer, when even a larger one is.
