Bang!

[ENVI XR6]

hmmmm im getting this large banging noise sometimes when i rev it up(only to 3500 to 4500) and drop the clutch...it doesnt happen all the time but sometimes. It sounds like a large rock being flicked up into the undercarraige of the car coming from the rear wheels..wat could this be??????

[Justin@]

its your car telling you not to do that.........

[Futura01]

agree with juzzy,

Sounds like whiplash from tailshaft and or trailing arms if live axle diff

[brenx]

My mates AU C2R does that. We've never found it. Big cracking sound from the frontish area on his.

Have you checked your engine & gearbox mounts?
This might be causing the exhaust to hit the body or rear suspension.

everyone knows its awesome to rip burnouts :hihi:

[howesy]

universal joints can sometimes give this so get em checked or keep doing it, something will break

Dropping the clutch while at 3500rpm or over i'de expect a bang from most cars anyway ..lol , most cars can't handle having the clutch dumped to many times like that without creating major slack in the diff,uni joints and everywhere else ! , which is probably creating the bang from doing it to many times in the past ..lol

But hey, as said above , everyone loves a good burnout !.. hehehe, cheers .

Any of your wheel weights missing haha, happened to me when i was cruisin along one day made me crap :

[AWD Chaser]

Seriously though...

I know the exact noise your getting. I get it when cornering hard in my car (auto). I have checked all my ball joints, etc, etc, and have even had new suspension put in since, and it still does it. I think it may be a mount that just moves a bit and hits the chassis.

First time it happened to me, I thought I flicked up a huge rock or stick...

[autickfordfairmont]

Could it be tailshaft hitting the floor, when dropping the clutch the *** end drops down, if your suspension is old it could be that hitting, have read on here before about that happening to people.

My AU doesnt do it, but its an auto, but my old EA use to do it occassionally, when really up it i would get a really loud bang/crack sound comming from about the middle of the car.

im not worried bout it hasnt done it for ages...i wasnt full on dumping the clutch..just hi revs and let it out quickly for a good start :

if the noise is coming from the front, it could be a broken engine mount, and the motor could be hitting the bonnet when launching... wouldnt be the first time i've seen that happen :

if you have an after market exhaust it might be banging where the pipe comes close to the irs
