Turbo Screen Option
Well in my search for a filter that could fit my VERY cramped bay(turbo inlet is pointing at the radiator at an extreme angle), I came up emtpy handed. I looked at mesh screens, but the amount of dirt they would let through was unacceptable to me.
So I found this K & N Pre-Charger Filter Wrap. It's part number E-3211PK. So far it works great. I did some highway pulls in boost and immediately pulled over, and found a nice amount of dust and dirt clung to the outside of the wrap. I would consider this wrap over ANY mesh screen, and it was only about $20 shipped from Summit. I mean I can actually see the dust still clung to the filterwrap, dust that would've made it's way to the turbo fins and eventually inside my engine...
The pic is not from when I did the highway pull, just from it was in my driveway...
For the lazy people who don't want to read the review, it's part number E-3211PK and can be found through Summit for around $20shipped. The part number is for the black screen, they actually have blue, red and yellow available as well.

Re: Turbo Screen Option (orangerex04)
im sure it deff picks up more then a screen.
The only thing that scares me on this stuff and screens is seeing dyno vids and watching the screens pulling in while under full load.
That just scares me now that I saw that. lol

you could always put a wide mesh behind the screen to prevent this. might flow less, but no pantyhose in your turbo

Re: Turbo Screen Option (itr206)
If you pull the screen tight and clamp it down really well, then you shouldn't have any problems with the turbo sucking it in under boost.
I think this is an excellent idea.
I wonder if it flows better or worse than an average screen? Did you feel a difference when you switched from a screen to this setup?

it wont flow anywhere near what a regular cone filter would flow.. there is soooooo many less holes for the air to get through.. think about it this way... half of your turbo being blocked off by the screen or whatever it it.. its usually some sort of "cross hatch" type pattern.. the filters are alot larger, and have the same style **** going on, but there is so much more area, to allow air to get through.

"The K&N PreCharger is a specially designed filter wrap made to extend the service interval of your K&N Filtercharger when used in very dusty conditions. They are made from durable polyester material containing a uniform weave. The PreCharger will stop small dirt particles with minimal restriction to the airflow of the filter. "-K & N Website
That's taken straight from the K & N website. In my opinion, I don't think K & N would make a piggyback of sorts for its filters, if they knew that the flow would be hurt significantly. I would rather run a full filter too, believe me, but space constraints don't allow me to.
The URL is http://knfilters.com/wraps.htm
It's an EG chassis by the way....

Re: (nojoke)
maybe you didnt understand what i was trying to say...
Less area < More area. you have to understand that.
what manifold are you running, that allows your turbo to be so close to the radiator?

Why? because a filter has a MUCH larger total surface area than just a screen. A screen only has the total surface area of pretty much just the diameter of the compressor intake, where as if you 'unwrap' a filter cone, you will see just how much total area it actually has. More area = more air flow, hence most of the filters these days are cone shaped and pleated which again increases the surface area a great deal more

ugh... i know...
i have the screen on there when im daily driving here and there, i dont rice around everywhere so i dont need the screen off all the time. when we were tuning i FORGOT to take the screen off. the whole purpose of me posting that information was just to show the restrictiveness of a screen.

another alternative is to use a section of ducting in the tight spot/tight radius areas to a hard pipe and then to a filter.
found some examples on the SDS site...
we used some on a MR2 and it worked well...

I was running a mesh screen for about 2 weeks. I did a top end pull and sucked the entire thing in and it spat some of it out the exh. when I started it up the next morning. I had it clamped on there pretty tight as well... for DD Im gonna find some sort of filter to put on... But I have 0 room for anything.
My compressor housing is touching the radiator and fan shroud. I dont trust screens anymore...
