Stock Turbo sounding bigger!

Hey guys, my brothers got a 2002 F250 and about 2 months ago it started to make this light whistle noise when you accelerated a bit. It just kept getting louder and now it sounds almost like he has a H2E in there or something! I road with him yesterday and the boost gauge only showed up to ten psi. I believe before it did almost 20psi. The mods it has are a TS 6 position chip, afe stage 2, built tranny, wicked wheel, throttle body spacer(useless), exhaust and CCV mod. Do you guys think the turbo is going on it or is the turbo just growing?! Thanks

Re: Stock Turbo sounding bigger!

If its getting louder and has less boost, It is soon to fail on him at the most inopertune time. Like 500 miles from home, in the rain or snow.

Pull the inkate boot, grab the compressor wheel and see if it moves around alot. If it does get it rebuilt ASAP.

My buddy waited too long and the compressor wheel bit into the housing so hard it snapped the turbine shaft. He said flames shot out of his stacks like 6 feet, I was like

Re: Stock Turbo sounding bigger!

Mine didnt shoot flames but it did the rest. Get that turbo rebuilt now! or it may not be rebuildable now because the noise your hearing is probibly a wheel rubbing.

Re: Stock Turbo sounding bigger!

It could be just a loose boot but I would deffinantly suggest checking the turbo.

We just got one in 2 days ago that the customer let go just a little too long. He said it started off with a squeel or whistle sound that got louder and louder as time went on and then it started making a growling noise and smoking a lot out the tailpipe. I told him to not be driving it and get in here as soon as possible.

Well a week later he called and said he suddenly heard a bunch of noise and lost power and was blowing lots of smoke and throwing sparks on his exhaust.

He towed it in here and this is what happens when you let those strange noises go too long.












I see a D66 from Beans in his future this time around...
