i was just wondering if i could put a cone style filter directly up to the turbo.. i have seen on a few trucks in magazines.. didnt know if it was just for show or if you could do it just thought i would ask.. only fear is the turbo heat melting something then ruining the turbo

 

Problem is it will suck in hot air.

 

You can, but make sure the cone filter can flow enough. Some of them do not have good CFM ratings.

About the hot air deal, I've tossed that one around a lot myself. Yes, the coldest possible air intake (to a point) is best, but on a turbo intake setup, the intake air is heated to about 525*F while going through the turbo, so any underhood heat is sort of a non-issue. What's an extra 20* at the filter when the air is getting pumped and pressed anyway?

That's what the itercooler does -- remove the turbo heat and get that air charge back to about 125*F. Get the intercooled air colder and you will see some performance gains. On puller and dyno trucks, I'd think that a pusher fan on the intercooler would help some. On a street truck, probably not so much, as the air from movement is going to do as much or more than a fan.

Want to get really radical? Install a liquid intercooler and run cold liquid to cool the air charge.

 

well thanks i am gonna try it and see how it goes..

 

I am currently running a big filter right off the primary turbo. Used a mandrel piece of tube, a straight rubber connector and a few clamps. Works great.
