"Saw a thread on another forum that interested me. As most of you know I
run speed density and got rid of my maf and intake pipe. I just have a
filter attatched to my turbo. Basically the point of this thread is to
consolidate facts and opinions on whether its better to run a pipe and
filter or just a filter or no filter at all. Apparently just running a
filter will damage both the turbo and engine being your sucking in hot
air behind the radiator. I put 6k miles on my car and haven't noticed any damage to the turbo. So, let the debate and fact war begin I guess."
I would do some logs with a pipe and without and see at least if there is performance gain with a pipe. Ive heard the same thing in regards to using a filter directly on the turbo could potentially cause failures. But it cant be any different than driving in warm summer conditions.
I dont believe it is unsafe but i can see a slight performance decrease without an intake pipe. For obvious reasons. The air entering the turbo is going to be warmer where as using a pipe would suck in air from a cooler area. Performance gains may not be huge at all but logically there has to be at least a small amount.
