Help weird noise

[Tookes]

Guys, please watch this short clip and listen for the squelch sound, it will happen in the near the beginning and towards the end of clip. It seems to happen when I really get on the throttle. Thanks

could that noise be the belt slipping on the secondary due to the shockwave? seems to happen both times as the trigger is applied under load. get yourself an infra red thermometer and check clutch temps. the hotter one is the slipping one. just a seat of the pants guess, but i bet you can feel a power loss when you hear the squeal.

it definitely sounded like the belt slipping to me.

Noises

Got a loose clamp on one of your intercooler hoses? sounds like a squeal of air leaking when the boost comes on. Maybe a small hole in a hose too.

thats belt sounds if i ever hear it, gassing it into the carve is big load, and i know i had belt issues on my sled, and bad slipping sounded EXACTLY like that.

time to figure out a new clutching setup!

 

[Tookes]

Thanks for the input, I had some of the same thoughts.

I think it sounds like your belt also

Hey Greg,

Pull your intake to your turbo off and quickly check you impeller blades, make sure your bearings are ok and there is no play on the blades. I does sound like a belt to me but you never know.

Kevin, if it is the bearings can that just be changed out?

 

[Motleyone]

No sir, you would have to send in the turbo. There are a couple places to do so. They would just send you a rebuilt turbo. I think they charge you about $600. My buddy had to do this along with another fellow from Spokane. I can get the info if you need it.

Greg what tunnel are you running?

I see. If it's the bearings wouldn't it make the noise constantly??

I'm running the stock tunnel.

Not always. Once it gets heated up and there is expansion there may be more noise and less clearance. I had the exact same noise. I run the VE tunnel with rear cooler delete kit. The VE plumbing kit runs right behind the secondary. A pin hole got rubbed into the pipe. Only under boost did it produce enough pressure to squirt radiator fluid out of that tiny tiny hole and of course it landed on my clutches. Caused a bad noise like yours.

Do you have a stiffer seconday spring you can try? Also, if you're running a shockwave, dial down the angle and see if it improves.

Definately sounds like the belt is slipping. If you run the same set-up again (with the same problem) try putting your hand on the seconday (careful - it's probably going to be hot). If your clutches are working well, they will feel warm, but you should be able to keep your hand on either one.

Secondary noticeably warmer than primary = secondary is slipping.
Primary noticeably warmer than seconday = primary is slipping.

I'm running the AC green secondary spring and it is stiff for sure.
