You guys just racing without a filter or running it all the time like that?

 

I take mine off when I race. I saw 50hp from a smaller wheel at 12psi, so its probably closer to 80hp with the 80mm wheel at 20psi

 

I'd probably try it buy it's a brand new engine....it's getting a filter for now.

 

Dont get me wrong, I keep it on at all times and only take it off when I go to the track. I will gladly take the 50 or 100hp hit for the engine to last a lot longer.

 

heres mine, i ran two stock paper filters in behind the front bumper, gets nice cold air and you dont have to worry about all the dirt the k+n lets into your motor!

Thanks for the thread, I'm getting ideas myself. On a semi-related topic, what are you turbo guys doing with the "fresh air hose" that normally plugs into the air intake and is connected on the other end right next to the coils? I've looked over a ton of pics, and can never determine where people ran this.

It could be as easy as drilling and tapping a barb into the silicone bend or something, but wanted to know what others have done.

 

You want to put a filter on it and vent it to atmosphere if you are referring to the line going to a barb on the front of the passenger side valve cover. This will allow the crankcase to release pressure from blow by in boost, and will keep the pressure from pushing seals out.

 

Yes, putting it in the section before the turbo will draw engine oil fumes through your turbo and into the engine...if you must, you can put a catch can here.

 

Looked over the pics again.

How bout a 90* bend right off the cobra elbow and point it down?

 

Yeah that's what I thought too. I've got a 90 and a 45 because there is somethings in the way.
