Turbo Noise!

[SuperDuty1]

Okay the other day I was making a run up north, pulling a trailer. The road I was on some steep hills. Anyways with cruise set on 60mph, going up these hills. The turbo would build about 14-15psi in O.Drive. I notice this strange noise I never heard before. It sounded like a chopping, or light popping noise. I am not sure I am explaining it correctly, but it would quickly return to normal when the load decreased. Is this the turbo surge that I have heard about? If so what can I do to fix it? 01' PSD AFE stage II, 4" Turbo back MBRP, 50hp Power Pup

Number one thing... not a good idea to pull hills in overdrive while towing.

As far as the popping noise, someone should be on soon that can help!

did your boost go up down when the popin started? yeah O.D. should be turned off if your gona pull something. wicked wheels will fix it if thats what it is.

Unless u have a BTS trans......

[SuperDuty1]

There was not a big change in boost maybe only 1psi. Just an unusual sound. As far as the trans goes, if it had to shift in and out of O. drive, I would have turned it off. But I always haul with O. drive, I have never seen my trans get over 170degrees. And that was with 19,000lbs behind it going down the interstate.

Hey Superduty, do you have a cold air induction on your rig? I think I know the sound you are talking about. Mine will do that too, even if you get on it hard empty.

[SuperDuty1]

Ya , I have AFE stage II intake. I very lightly here it when empty. This was the first time that I had heard the noise this loud. I am thinking of putting an ATS ported compressor housing on. Has anyone notice any kind of change or have used one. Also can I change the compressor wheel or do I need to use the stock one?

[lilredpowerstroke]

It sounds like surge to me. If you go with the ATS housing leave the stock wheel in. It is more efficent than the wicked wheel with the ported housing.

Cool, thanks for the info. I think I am going to order ATS housing.

So, I'm fairly new to diesels- only had my 2000 F250 for a year. Today I installed Banks Monster exhaust and when I was finished, I took my truck for a ride. Going up long steady hill, I was trying to get up to 70mph and was pushing the throttle pretty hard. Unfortunately, I wasn't paying attention to boost levels or RPM, I was watching my EGT's for a comparison of what I was producing the day before (250 degrees less). Anyway, the pickup almost wouldn't make it to 70, the turbo started making a weird noise; it sounded like it was spooling up strong but then it started making the noise like it wasn't getting enough air or it wasn't able to pressurize it like it should have. I know this is a pretty crappy description and I'm hoping there are others who have experienced this phenomenon who can tell me what it is. I have already ordered a compressor wheel from XDP- I'm just waiting for it to arrive. Is it possible to replaced the compressor wheel without removing the turbo? I had to take the turbo out to get the bolts on the power elbow torqued properly and I'm not looking forward to that whole mess again. Thanks everybody!
