Re: Name that sound

Loose nuts and bolts dragging the ground?
J/K I know...I know most of them are missing....

Tires flapping?

Did you have Mexican food for dinner before racing?

We warned you about that......

Re: Name that sound

Did you hear the sound in the truck or were there any indications of something off?

I was thinking it could have been the way the video camera processed recording audio at that particular time in the pass?

And what's up with the radio talk show or whatever that was?

Oh...and I'm not sure if your screwing with us about that sound or not? I dunno?

Not screwing with you!

It sounds like a giant fart going past. I thought either the wastegate was opening or perhaps a gasket lket rip somewhere. Maybe it's knock or backfire? Just trying to figure it out!

Re: Name that sound

Ok. Sorry. Wasn't sure. Was thinking that if you were for real you would have included anything that may have stood out on the truck during that run (if anything).
A sound that loud I would assume that you would hear inside the truck as well? I don't know what caused it, but now I am just as curious as you are to find out.

Re: Name that sound

Well the engine is loud, I have solid mounts and it was coming from the exhaust so I think it was the wastegate potentially..

Re: Name that sound

dunno what muffler you have. but in saudie they installed a different one>? maybe something let go in the muffler and makes a sound like that. it's flapping in exaust pressure?
was it a straight through?

if that is the case. a whole lot of your car running like shit in the states might be the reason of something clogging your exhaust, and now it let go making that sound.

It's a straight through after the turbo but not the muffler I don't think.

So not the wastegate? Maybe the muffler like you said...

The running like shit is the tapping noise and the top end of the tune, otherwise it's good. Looks like my valve springs might not be ideal. Calling RPM today and preparing to take the driver's side head off and the lower intake to check the lifters and the valves... Not sure yet but seems like it might be necessary :tdown:

Ya, it's got a Turbo
Re: Name that sound

If you know your valve springs are weak, I'd start there. Depending on what gear you were in. and what RPM you were at, it could have been popping back through the intake if the valves weren't closing. Same thing could apply to your exhaust valves. Think about how a Jake Brake sounds.

I think it was Jimmy letting them rip while standing next to the camera guy.

On a more serious note, possible misfire out the exhaust. If there is something wrong in the valve train (weak spring ect...) and your underload in 3rd gear, it's possible that the problem presents itself in this situation (high boost under load).

Would be nice to datalog thru the condition and see if it records anything.
