Im Stumped

Ok there is a slight whirring noise that hits right about 1500-1700 rpm then goes away. I just had the turbo rebuilt by htt so it isn't that. The only thing I could think of is the airdog has air in it? The problem is the air dog isn't noisy at Idle it sounds like it always did, plus the noise only kicks in at 1500-1700 rpm. It used to kick in at about 1500-2000 rpm and be about twice as loud, now it doesn't do it as loud but it is still there. I had the manifold etc smoke checked for leaks. Maybe im wrong but the airdog puts out the same pressure at idle as when your going right? So if it isnt noisy at idle it shouldnt be while under load? Maybe im wrong this is driving me crazy though. Could it be a fuse or something electronic? When the noise started I was gunning the truck up a hill the instant I came out of a steep dip on the downhill, the noise was quite a significant whirr then. I had an outlet that you can plug a 3 prong plug into, plugged into my power outlet, and it started smoking about 30 secs after the noise started. So could it be something electric? Ahhhhh!!!! I am stumped and extremely frustrated, any help is greatly appreciated. Oh by the way My rebuilt turbo from Htt is awesome!!! I just had the hy 35 rebuilt total cost with shipping was $500. They received the turbo on Monday and I had it back and installed it this Friday. I highly reccomend them. It looks brand new, and the truck is so much quicker now.

Because of money and also im not doing any chips or fueling mods other than the air dog for reliabilitym, plus I really dont get into the throttle to often anyways.

If you removed the stock fuel filter you most likely just re-installed the old bolts in the manifold. If so the 2 bolts are too long and don't tighten enough to hold the gasket. I would double check that and replace the bolts with shorter ones.

Do you have a fuel pressure gauge to verify pressure from your AirDog?

Do you have a boost gauge to verify boost pressure?

If not you going to need the feul pressure gauge for sure. But on the boost pressure you can use a test cap and pressurize the system with about 20 PSI and soap up all areas where air is... Manifold, boots, intercooler, tubro connections, MAP & IAT sensors, Etc...

Its strange that the noise goes away though, and only occurs during a certain RPM range. Thats the part that gets me.

Does it have anything to do with speed at all, or does it do it in every gear?
What about in reverse?
Does it happen under all throttle conditions as well? i.e. light, medium and heavy?

Ya I don't have a fuel pressure gauge yet, going to get it as soon as possible, im kind of juggling car repairs right now, but ya I need to quit putting that one off. I don't have a boost gauge but I brought it to a diesel mechanic about a week and a half ago and they said my boost was good. But then again those guys didn't help me a bit they just told me what I thought it was, (We were both wrong, so that was a waste of $80 bucks, that and they just tried to sell me **** like ,$130 for brake fluid flush, and $130 for PS fluid flush etc.... they wont be getting any business from me again. That was before the turbo rebuild. I am going to double check where the old fuel filter was as soon as I get home.

Sorry let me clarify the noise stays if is in that range band on the rpm, it does it in every gear including reverse, and I can hear it under all throttle conditions except heavy. On heavy throttle it gets out of the range so quickly, that you really don't notice it. Doesn't sound like transmision does it? I don't have any shifting problems. As far as I can tell the noise is coming from the drivers side. Hope that helps.

Could also be a harmonic for the air flow. When I added my ram air hood, I got a whistle sound through a certain RPM range in every gear. Not as pronounced of a whir as the turbo, but definitely a predictable sound. Since you changed your turbo and air intake geometry, my question is, did the sound start right after the changes?

No the noise started before the turbo change, we thought it was the bearings going out on the turbo, which is wasn't only the shaft on the turbo needed to be ground. I had them do a full rebuild basically just because it was already at the shop, and I had budgeted the money for it already, plus I wanted the peace of mind.

Also you can't hear the noise revving the truck up in park, it has to be under load to hear the noise.
