I just installed an air to air intercooler on my STS powered truck. When I step on the gas it whistles. Anyone know why!!! Now it really sounds like a jet comming down the street!!!

 

Hole in IC?? Burst seam on IC?? Hole in air-to-air boot?? Just throwing those out there.

 

Thats what Im thinking. Are you using T bolt clamps or regular clamps?? Sounds like you have air escaping somewhere.

 

Im using regular hose clamps. Ill have to check the connections tommorrow eith soapy water while tyhe engine is on. The IC is brand new and was pressure tested so it should be good!!

 

You might wanna head to a Kenworth or Freightliner dealer and snag some actual intercooler clamps that have a spring in them. I dont think normal hose clamps will cut it. You can put soo much more tension on the t-bar clamps..

 

i just picked some of these up, anyone running an FI setup should be picking these up saves the headaches of having to pull over after a WOT pass to put your piping back together
