I'm using this one currently, good for the street but when I'm racing or on the dyno it comes off.

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

stevieturbo

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

chinaoreo

Thanks for the reply.. so would u say that it robs a noticible amount of power then.. ?

A large filter with lots of surface area robs power. This little flat filter will rob tons of power

I wouldn't say that its a night and day difference for power, I'd say its pretty minimal, it does affect spool a little but not enough for me to care.
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.

Oh really

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.

jordoza

I couldnt get it out of my head so i looked it up its not silicone intakes its called intake hoses. Just look up cobra inyake elbow and the first place that comes up is intake hoses.

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.

What in the heck?

jordoza

I honestly think each individual set up is going to react differently. My set up was a LSX376 with s480 t4 96mm turbine making just under 10 pounds to make that 770rwhp. I dont think at 10 pounds that set up was a restriction. Im sure by the time i reached 18 psi it was but i never took the time to test it again. I can for sure that at 10 psi it made a2 hp difference but back to back runs on the chassis dyno will see a difference of that much with no changes so i equate that little of a difference to no difference at all.

At 5 psi my procharger inlet hat and filter was a restriction...

chinaoreo

******..u have this clamped to a turbo.. ? Just making sure it has a hose clamp style flange.. can’t find anymore pics of it anywhere

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?

AndyTA

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.

No one is arguing whether or not an air filter is a restriction. Your comment was misleading:
A large air filter is less restriction than a small air filter. The more surface area the less restriction.

AndyTA

To be fair.. he said:

"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.
