Last year whilst on me holibobs I drove through part of Germany, and so like any right thinking petrol head stood on the go pedal. Only to be disappointed as after the 100 mark car ran out of steam and eventually topped out at 110-115ish.
I'm pretty certain it's nowt daft like plugs or the various filters as they all get changed regularly.
Any of you brain boxes got any suggestions, they would be greatly appreciated

Ta very muchly,
Simon.

timing belt set up correctly?

multi rams working correctly?

[swordfish]

sell the 2.2 and buy a 3.0 v6 

[Simon270172]

Well, the timing was spot on and checked over and over due to my OCD tendency's on the last change.
I did at one point convince myself the multi-rams weren't working correctly due to what I considered a lack of torque but it all checks out as being plumbed up right with no leaks that I can find and the actuators all seem to be operating.
Thanks for the response,
Simon.

I would certainly consider that if indeed I had a desmond but even with a 2.0 8v I would expect better than 110....
Cheers,
Simon

I dont think the omega is suited to you then,go and buy a bmw m5
As for a 2.0 8v pulling nearly 1.8 tonnes of metal along and expect it to exceed 110 mph i dont think so,my beast has never hit top end as there isnt anywhere in the uk i can try it out at,and to be honest my set up is more for upsetting corsa boy racers etc.

I appreciate your opinion and thank you for it, but I cant agree apart from the corsa bit.
I'm not exactly new to this size/type of vehicle. I got my first 1.8 carb'd Carlton in 1990 and that would easily indicate the speeds we're talking about. I've also had 4 other 2.0L Carltons and 2 3.0L Senators as well as this omega that I've owned since 2003 and in between those there has been others.
I think I know what to expect in terms of performance and I don't feel that at this moment in time my omega is as it should be, which is why I was asking for help and suggestions. I did not expect what seems to me a hostile response by you telling me to go and buy an M5.
I love my omega and it's exactly the kind of car I should have.
I know you cant max out your car in the UK and I would never advocate anyone doing so, but I was on an empty stretch of autobahn that allowed me to safely try.
All I wanted was to join in with everyone else and talk about omegas and in doing so perhaps solve a few issues with the cars.

3.0 senators had a restricted top end of 130mph and the 2.5 and 2.6 were less than that.
You havnt stated what mileage yours has done either,you just may have a lazy engine that wont go above the speed you stated,but your not going to be able to do that on a uk road unless you want a ban,speed isnt everything,and so long as you and your family arrive at the destination in tact and alive that should be more important than speed.

[TheBoy]

The 2.5 is geared lower than the 3.0, and lacks the bigger engine's pace a high speed.  Still, I know there can do 120 with little effort (but needs a lot of room to wind up once its in top gear), and the 3.0l cammed, superchipped variants are slightly (but not massively) better.  Neither are in the same league as the 3.0l though, although even these need a lot of space once they drop into top at a shade under 130

Both our old 2.5V6 Elites (Estate & Saloon) would easily easily reach an indicated 130 mph, with a feeling that given time and space they would go a bit faster.  I'd still be inclined to look at timing

[TheBoy]

And we know, as OOFers, that the standard 2.6/3.2 lack the real world acceleration of the 2.5/3.0, in order to appease the tree huggers.

[Twintop]

My 3.2 isnt for tree huggers 

[TheBoy]

Aye, but I'm guessing by your username, it isn't as it left ze Germans...

[Simon270172]

I'm the one who pisses everyone else off for driving like a granddad, I just happened to be in Germany when the opportunity presented itself and the car let me down.
It has 146,000mls on it, but to be honest I think its just nicely run in from a purely mechanical point of view. Smooth and quiet, revs freely, kicks down well. Basically behaves as you would expect apart from 100 onwards where it just went flat.
TBH I was thinking along the lines of fuel supply or lack of.

Are you sure about those figures? I've seen more than that in both my Senators(not in the UK) and one was a 12v at that.

[Simon270172]

Oh... peoples talking
Soooo......any suggestions other than getting a 3L or a supercharger??
Fuel pump maybe?
