Title: Vibration at 80mph
Post by: Chewy34 on 03 November 2014, 06:17:52
Hi All,

New omega driver here. Just bought a 1996 2.5v6 and drove it home last night. Managed to get fairly scared as the while car vibrated when I got to 80mph. Dry much coming from the front end it felt worse than just balancing..

Sort of felt worse when going round a bend (drove me round the bend!)..

Any ideas gratefully received..  :)

Loose wheel? Wheel imbalance? Track rod end gone? I would swop wheels back to front, while front wheels are off look for anything loose, like the steering bottom ball joint.

Best not to hammer it too much at first as it,s an unknown quantity. When you get used to it and its many little
foibles you should be ok to thrash. ;)

Have a peek at the front tyres with the steering hard right/ left. You could have uneven wear that is causing the vibration. Omegas can get down to the wires on front tyres if geometry is out and it's not readily noticeable until you examine the tyres under full lock.

One of those 1 post wonders.

I find it very odd that someone would take the time to sign up to a forum, start a thread and then never come back.

Meh!  :-\

Rear balancing tends to show up around that sort of speed.

I learned on my speed awareness course that the average speed on English motorways is 82mph. Parliament considered raising the limit to 80, but decided not to as then we would all go along at 92.

My satnav tells me that at a genuine 82mph my speedos read an optimistic 90mph, except in my ex-plod, which reads 82.

I use the 10%+2 as a hypothetical limit... might get a tug if they're bored, but shouldn't be fast enough to worry the camera vans :-\

Remember kids, speeding is naughty ;D

Why don't we just have a suitable / sensible speed limit that we all stick to and is actually enforced? Would love to understand the social process that has occured where speed 'limits' are now seen as flexible. (I include myself in that sometime)

The simple and logical answer is that a speed limit is only as good as the read-outs (the speedometers) in cars.

Increase the speed-limit to 100mph, and you have the 10% rule (acceptable variation in speedo), so technically, someone doing 110MPH could not be prosecuted.

I believe the law is 10% + 2.  So, at Motorway limits (70MPH) the 'allowed' speed is actually 79MPH.

On all the motorway roadworks at the moment and the SPECS set at 50MPH, I bang the cruise on an indicated 55MPH and I've not had a ticket yet.  Bear in mind I'm probably only doing 51 or 52MPH.  I'd guess the SPECS are set to report at 57MPH.  In that, I am well below the limit (at the indicated 55MPH).

Digressing from the OP

it p's me off when I'm following a car at 33/34 in a 30 which then stays at 33/34 in a 40 limit & the same again in a 60/NSL!  >:( >:( READ THE FRIGGING SIGNS ..........

and don't come the 'speed limits aren't a target' routine  ::)

No, they're guidance for the rising percentage of drivers who can only "drive by numbers". Give them a 40 MPH bend in the wet in a 60 MPH speed limit and they are straight into the undergrowth, so a 40 MPH limit it has to be.  ::)

When I did the dreaded safety course recently, we were asked for various ways to avoid speeding. I proposed cruise, which I try to use as you do. " No No no", says the instructor ( a lady advanced motorcycle trainer ???), "that will reduce your attention on the speed." ??? ??? ??? :-X

If I'd been in your shoes there would probably have been an audible "pop" as my brain imploded at that point..

Well I must admit, I immediately said "What utter rubbish", which she chose to ignore, fortunately, as I still passed.

Reminds me of that bit I read in one of Clarkson's books - he was attending a 'road safety how to drive properly advanced motorist jobby course day lecture things' and he lost any faith in what the instructor was saying when they told him the correct, safe way to overtake a vehicle is to move over to the right hand side of the road then change down a gear, then accelerate  :o  :o

Post by: 05omegav6 on 19 November 2014, 10:58:23
Yup... Indicate, foot down, pull out, ecu wakes up, car kicks down, this wakes the turbo and the car finally accelerates properly... Granted, that process only takes a second or two, but... :y
Title: Re: Vibration at 80mph
Post by: Diamond Black Geezer on 19 November 2014, 11:36:52
Yup that's about right  ::)

Strangely I find myself slowing a little, leaving a nicer gap, then indicating, throttle, then pull out, acceleration. Does means sometimes a slightly unnerving gap between the right hand corner of the lorry trailer and the nearside Omegas headlight, though!  ;)

Probably on a par with the Edwardian signal box then. ;) ;D

Even the 2.2  sport was able to keep up better (Ie, change down (and up) quicker than the manual) on the way to the curry house. :)

Anyone who is worried about breaking the speed limit should buy a people carrier. The slightest cross wind will make you desist and loathe to do it again. ;D

Actually I'm sure i've seen a program on the police high speed driving thing and they do say pull out, ensure the road is clear then toe it.

Perfectly acceptable IF you are driving a powerfull car.

Think about it, you see a slower car, think its clear, boot it hard, pull out, its not clear so slam on to pull back in, risk hitting the car you are overtaking or a head on. On the other hand, you move over, way isn't clear you slot straight back in no drama or accelerate past.

Which is more sensible??

Obviously with an underpowered euro shitbox, pre planning and momentum is a lot more important, but if you are relying on momentum to get you past as opposed to power is it actually a safe overtake you are attempting??

Fair point, I think that's the logic behind it. For me, it's that difference between passing your driving test, and then learning to drive, kind of thing.

The stuff I've learned, and am still learning astonishes me weekly.
