Turbo noise

Thought I would post this up maybe you all can help? My dad has an 06 F-250 6.0. He pulls a 35ft fifth down south for the winter. He said when he was pulling a long pull up a medium grade he got a whooshing sound from the turbo! Any Ideas Im not sure if the 6.0's have a surge problem or not? His truck is stock. Thanks!

Okay just got off the horn with the ole man, and whoosing would not be the correct sound He said it was like the turbo would race like it was coming out from under the hood! I don't know what turbo surge is, or what it sounds like, but too me that sounds like turbo surge? Is that an issue with the 6.0's? Thanks any feedback would be appreciated

i believe its a "turbo fart" ask him if it happens when he is on it hard and the quickly lets out, its is normal and nothing to worry about its the turbo backpressure coming back through the intake, even the most stock of trucks can do it and its more prominent with aftermarket intakes

Actually he said it sounded like it was racing faster, so he let off the gas and it went back to normal. He said it has happend a couple of times now. Its usually when he is pushing it hard! I told him he should at the very least invest in some gauges!! I dont think it was the fan he was certain it was the turbo making the noise. I thought I read about somone saying there is a TSB for turbo surge on the 6.0 is that correct, or was it just because it was late and I was seeing things? Thanks for the input I appreciate it

Completely normal, nothing to get concerned about. It's the fan engaging - I get it quite frequently pulling my 13,000Lb fiver going upgrade, or in stop/go traffic.

When you are working the truck hard (aka a long pull up a steep grade) the coolant temp will rise enough to engage the fan clutch. The fan doesn't turn full speed unless the coolant temp rises to a set temperature. I am assuming that this is 200 degrees, but I don't know for sure. When things get warm enough the clutch engages much like a torque converter locking up. This spins the fan at full engine speed and makes a horrendous noise. When the fan clutch is locked up, it roars much like you are describing.

I wouldn't worry about it, but getting good gauges is advisable. The other turbo fart noise does not occur when you are on the throttle but rather when you let of the throttle rapidly when the turbo is making signifigant boost. I don't think this is what you are experiencing.

Good luck.
