Just did cac pipe and ccv mod

Seems like my truck runs slightly hotter and a weird howl that gets louder with rpms. And a different kind of knock to the engine.

Boots seem tight and ccv tube is not kinked at all.

Any ideas?

When I put my CAC pipe it changed the tone of my engine a bit, but didnt make things run hotter. I would check your boots with some soapy water to see if you have a boost leak. What do you boost numbers look like compared to before? I dont know what to say about the knock though...

They seem to either be higher or just get there quicker.
I've only driven her twice since all this and I think engine just isn't use to be able to breath clean air.
It might just be my imagination that its running hotter.

I will have to go back and look at my data logs. Before I do a new mod I always go out and log some data at half skinny pedal and WOT just to get a before and after numbers. Ill see if mine changed any.

When used in conjunction with a high flow intake elbow, and downpipe it will drop your EGT's a decent amount. I saw 150 degree drop at WOT after the install of all three. Some report a slightly quicker spool up. I believe I saw this, but it wasnt a seat of the pants difference.

I agree. It doesnt look that crimped, and then you pull it out and you see the mess that it is. It was a terrible design from ford from the get go. It always makes me laugh when you see stuff like that. Is it really that hard to make a radiator support about a 1/2" wider and fit the pipe in from the factory?
