whine at winddown

[Bradley G]

After doing a burnout I hear a whineing sound as soon as I release my foot off the gas, until the wheels stop .Is this normal ?

Brad, where did you do this? You are a stone throw away so you better share :)

I've heard it after a burnout too. I'm sure more experienced people can answer this one though.

NO , But if you tell me where, I'll try and top it :D

...Brad...that is in front of my house...you aren't telling me that you were the second burn out mark that went over mine, are you?

hehe, the burnout is now pretty old...I think 3 or 4 weeks? Whenever I got my new tires put on - those are the old ones last marks. Since I did that burnout I've attracted others and there are like 2 or 3 marks now.
Is this burnout with your MM ? Powerbraking or just launching?

[jstevens]

I believe the whining sound is the torque converter.

Again, maybe a gearhead can respond with more info.

It does not sound bad,I kinda like it.

I was just curious if anyone with an '2004 W/ 4:10's experienced this.
And If was normal for this vehicle.

I know that many of the 2003 Marauders have the clutch type alternator pullies on them, and that can cause some whining during deceleration. the one on my car always did until I installed the Trilogy supercharger kit which does away with the alternator pulley clutch.


I'm not sure if any of the 04 Marauders have that, but the easiest way to tell if your car does is to take it up on an empty stretch of highway late at night, and watch the headlight beams as you hit full throtle. if they dim while the engine is under full throttle, then your car has that alternator clutch, and that's the cause of that whining upon deceleration. there's nothing wrong with your car, although I hated that sound too, and I'm glad that my Marauder doesn't make that sound anymore.

[Bradley G]

No!, But that is a bad idea!:nono:

My wife comes unglued if the wheels spin:rolleyes:
I can not ride her on this,26 yrs. worth:lovies2: , and it's waay cheaper to suffer!J/K;)

Sure sounded like driveline, trans or rear end,I am gonna go listen some more!:burnout: Thanks Billy!, and check out the lights to see if they dim.

Bradley GYeah Brad, when I had that weird pulley clutch thing on my Marauder, it always sounded to me like it was coming from underneath the car too, but somebody on here told me about it, and sure enough as soon as I removed that thing during the Supercharger installation, I noticed two things:

#1. The headlights never dimmed anymore during full throttle blasts.


#2. The whine upon deceleration didn't occur anymore either.

[Bradley G]

Cool Billy,I take your word for it!

Can I still go and listen some more?:D
If I were to suprize the wifester with a supercharger, which do you suppose would whine more?:lol:

Bradley GUhmmm, okay Brad, go and watch my burnout vid again, and tell me if you hear any whining. ;) BTW, I know that you're joking, but some people who have driven Marauders that have both types of S/Cers on them claim that the centrifugal S/Cers whine more than the roots ones do.

But I'm meely going by what I've heard others say. I also read one of Lidio's posts recently where he claimed the addition of the cold air intakes and/or K &N filter upgrades cause the whine of the Trilogy S/Ced Marauders to be louder. I think that must be true since my car has the stock air tube and filter on it, and it's a whole lot less whine than Marauders like Dave's car emits (aka "MI2QWIK4U"). And I believe that Dave's car has an aftermarket air intake tube on it.

[Bradley G]

I agree that the factory intake muffels the cabin sound quite a bit!
I like the sound of all superchargers, headers, and NOS Too!
Thier is someting especially cool about the stealth thing too Billy!
Got to keep them guessing:hmmm:

I believe the whining sound is the torque converter.
If not that, something close to it?

It sounds like a whine that feels like it's coming from under my right foot, near the center hump? I've heard/felt this sound a thousand times now, all around the same conditions too.

If you're N/A, or, blown with a centrifugal style system, you will hear/feel this. If you have a Roots system in place, ithis sound/feel is there, but masked by the blower's native sound. Both whines seem to share the same frequency.

Jumping out of the throttle too fast while doing a burnout seems to inspire this noise/vibration. It may be present under other conditions, such as "in the traps" at 110+ MPH at a local drag strip, but I can't hear it, or, feel it all by itself then, because of all the other noise and vibration at this same time. I do hear/feel it after a burnout, and after the waterbox.

I can't say its the torque converter for sure, my first MM had the PI Stallion single plate, and my present MM has the triple plate, and both cars made/make this noise. So, I'm going to post my guess (which is as good as anything you have read so far) and suggest that it's the tranny's front pump winding down. Prepped to pump, it's just relaxing after release of the throttle, no harm done. It is a "false alarm" to the tranny, but one that doesn't upset anything long term. Your tranny fluid temp will spike high, but should cool in a short time.

One thing that's been a steady trigger for this whine for me, has been burn outs. Mostly in the water box at the track, I hear this whine a lot. Come to think of it, I have not not heard this whine after the water box at the strip, and I do not do burnouts on the street anymore, so, IMHO, it's normal, and it occurs when one lifts their right foot too quickly from the throttle after a brake torque, launch, or, burnout.

My advice here has always been to get into the throttle with a 1-2-3 count, rather than just hammer it from a dry standing start. This earns better traction and lower ETs. My advice for getting out of the throttle is likewise, pull out with the same 1-2-3 count. Whether launching, or, stopping on the track, or, the street, the Marauder does not respond well to sudden and intense throttle changes. Apply some split second patience, and it all works smoother. Try pulling out slower, and see what follows?

[BillyGman]

okay, there's one way to test my theory for certian. If you have the clutch operated alternator pulley (which you do if the headlights dim upon WOT like I've explained in a previous post here) then you can simply remove the serpentine belt completely, and start your engine and drive down the street a couple hindred feet and make a couple full throttle blasts and l;isten for that same whine. if you don't hear it anymore, then it IS that alternator pulley clutch that I've mentioned, and if you still hear it, then I'm wrong about that.


It's no big deal to drive a short distance with your serpentine belt off. Many guys at the drag strip do it all the time for their quartermile runs. Just realize that your will be without your powersteering while that belt is off. I cannot try this on my car since it wouldn't do any good because of the fact that my car doesn't make that noise anymore since I've removed that alternator pulley clutch. So if you really want to get to the bottom of whether it's that pulley cluth or not, that's what you can do to find out.

[Lidio]

Like Billy suggested, the wine after a burn out or abrupt engine deceleration is the one-way-roller or clutched alternator pulley that stock MM's have. This is why they have the one way roller. Because today’s high amp/powerful alternators have become heavier internally, they have more inertia built up in them, and also poor pulley belt rap would make the belt squeal other wise when the engine decelerates abruptly. This wine last for about 2-4 seconds after you get out of the throttle from typically a burn out. Because Trilogy equipped MM's have to remount the alternator back wards, the one roller pulley has to be removed for proper operation. So the Trilogy equipped MMs will squeal the belt some times under these conditions. Its no big deal other then an occasional noise that has to be excepted.

[Bradley G]

Thanks guys! That makes sense to me!

It sounds exactly the same way every time!

It was a while back, but I read here that this one-way clutch was discontinued for '04 MMs, maybe some late '03 300Bs as well. Can you confirm this?

Anyone?

As far as I know and have seen, the clutched pulley is on all years of MM's and a few other Ford products as well.



Thanks

I have to be honest it did not worry me cause it did not have a it's gonna break kind'a sound:rolleyes: !

I thought it was cool!
Back at the track;
As I finished my burnout, I took my foot off the brake a little too soon( I thought the wheels had stopped)and I shot past the stageing spot by a foot or two!:o

My car did the same thing yesterday, kind of made me worried, but its still together

[BillyGman]

If you take your car up on the highway late at night and look for the headlights dimming like I've previously suggested, you'll find out for certain if your 03 or 04 Marauder has the pulley clutch or not that we're talking about here.


And then if anyone who finds that their Marauder does have that clutch pulley, if they really are still skeptical about what I've been claiming here in this thread, and they really want to find out for certain what that noise is with a positive diagnosis instead of arguing about this over the internet, then they can simply remove the serpentine belt and take the car for a short ride which includes a couple full throttle blasts like I've also previously stated here. :rolleyes:

Don't feel bad. Same situation here and honestly with most guys! You just have to grin and bear it. I have to drive my MM like an old grannie with her. Yet, we better not, ever take her T-Bird some where and not go in the MM???? I have to creep along with the MM or I'm told I'm racing, racing !!!! HA!!
