I installed the Ford AIS system and I dont hear anymore chatter or surge coming from the Turbo. I took my truck up some hills that would cause the chatter before, but now it is gone. I did drill two 2 inch holes in the front of the grill for better air flow.

Gotta love the extra air along with the knowledge that it is clean air getting pulled in!!!
Love the AIS!!!

What kind of intake did you have before?

 

[nmhs]

Sorry, I had the K & N Air intake system.

The FIPK? If so, the reason it stopped chattering is becaue you restricted airflow, do the fender sleeve deal and I bet the surge would come back.

Its prolly still there, you just cant hear it.

Agreed...

If he had surge at all. So many people confuse the back wash when you lift the throttle with surge that its getting hard to find somebody that truly has experienced surge or really knows what it is.

Well here is a little history of what I have done. A while back I went from stock to the AFE stage 1. I couldn't notice any chatter from the turbo with that setup. Then I went to the K&N FIPK and when I would climb hills at lower rpms I would then here the turbo chattering. Then I recently installed the AIS and I have not heard any chatter. I assume there is a difference between turbo chatter and surge?

I live on a really dusty road so decided to take the K&N off. I inspected the intake, and the turbo. From what I could tell it looked pretty clean inside. In fact I didn't notice any dust particles in the K&N intake. I think I will keep the AIS.

When I would climb a hill with low RPM a sound would come from the turbo that sounded like ch.ch.ch.ch.ch. Like it was chattering and gasping for air.

I do hear the other noise that comes from the turbo right after my Auto shifts and it sounds like whhoooosh....I believe this to be normal though.

Hope you like my sound mimics /ubbthreads/images/graemlins/smile.gif /ubbthreads/images/graemlins/smile.gif

The whooosh is normal.

What RPMs are you running when the Cha Cha Cha occurs? Surge is normally in the 1600 to 2000 RPM range and will go away when you give it more throttle. It is also noticeable on the boost gauge.

I would watch the boost gauge when this was occuring and it did not flutter or anything like that? NMHS

 

[Dubco1]

Go on Greg Robs video page and there is a video from inside a truck that is experiencing surge. It is audible and visible on the boost gauge. You will have to look around to find it but it is a clear example of surge.

FOMOGO

 

[gregrob]

I think this is the video.
POS BB Turbo Surge

 

[nmhs]

Well I watched the video and it was similar to what I was experiencing. But I tell you it isnt' doing it anymore. strange. I will keep an eye on this. Thanks for the help everyone.

NO, but I'm pretty sure it's Kainers' truck, you could ask him.
