Title: Help me get my ROAR back!!
Post by: chuck_g on 22 May 2008, 23:32:01
Hey all, i recently bought a 2.5 V6 Omega and as everyone knows or shud know V6 sounds mint!!! I threw an induction cone in to give it that extra ROAR but as alot of people know Opel and Induction do not mix well and long story short my airflow censor started acting up!!

So out came the cone and now theres no throaty grunt wen i plant the shoe!!! Can anyone recommend a way to get this roar i so need without affecting my performance!!! Thanks

I suggest that the V6 inlet system is already optimised to maximise engine power throughout the RPM band. To interfere with the induction is probibly not a good idea since other attempts by other forum members were unsuccessful and actually resulted in a loss of performance.

I plan to fit a K&N air filter this month which maximise air flow to the engine but that is the extent to which improvement seems practical. :y

I am very curious to see what responses you get from the more knowledgable OOF members to this topic ;)

Put it all back to original !!!

The airbox is plenty big enough and does NOT restrict the flow at all.

There is no performance increase in changing the system.

In fact, sticking cone filters/K&N filters etc etc  can actually lead to a LOSS of power, as you are now sucking warm air in instead of the cold air as designed.

If this is what you want for a few micro-decibels of noise ... fine .. but the Omega is a smooth, luxury vehicle .. NOT a chav-mobile..

Leave things as designed .. :)

get an unoiled panel filter and use standard system drill the airbox at the bottom front and wing side that will get you v6 noise with no hot air escaping in!

thats what i have done to my mig until the noise started annoying me!!

No offence mate, but most here would rather have reduced noise, not more. Cheap crappy after market exhausts and cats have generated loads of complaints from us abouts noise. Drives you mad after not very long at all. It sounds to me like you've got the original setup so my advice is look after it and don't mess with it. There's nothing cool about a chaved up Mig (or a chaved up Corsa for that matter)

IMO people who consider anyone who drives a loud car to be chav is a seriously narrow minded individual who has to learn how to have their own opinion and not have there life led by the media. in other words get a life!  :y

Have you ever heard the saying "if its to loud your too old"?   ::)

My omega is as loud as all hell! (im not a "chav" just not a OAP either!) the previous owner has completely removed the bottom part of the airbox and cable tied / taped the filter on, never caused me any problems and makes changing the filter really easy lol.

On idle and light throttle there isnt much diffrence, but when the pedal hits the floor it roars like a beast!

And yes i am more than aware that it will suck in warm air when the car is standing still, but how often do you need full power from a standstill? it will lose some low end torque but gain some high end horses, which suits my driving style.

Mmm so if we don't agree with YOU we are narrow minded, unable to have our own opinion, lead by the media and don't have a life ????

Methinks you need to rethink where you stand. EVERYONE is entitled to an opinion... just 'cos we don't like yours, or you don't like ours, doesn't make either more valid.

However, comments like yours have certainly given me an insight to your attitude.

I don't see anywhere in the above quote which mentions opinions, you are telling someone "facts" which are untrue.

The loudest cars i have ever heard have all been motor sport cars, from your "FACTS" that a loud car is a "chav mobile", so in effect your saying that everyone in motor sport is a chav?

Also further to your FACTS above, unlike yourself im not a part of the R&D team for Vauxhall (although i am involved in R&D for motor sport) but i find it almost impossible to believe that any car manufacturer would design their standard air box (which covers multiple engines) for performance and forget about economy. which in my book, suggests your FACTS above are untrue.

And to answer your question, yes everyone is entitled to their own opinion, but i do not feel people should be allowed to portray lies as facts to uneducated fellow owner's club members  :y

My opinion is that every car should be built for performance and they should all be as loud as 747's! (although living next to a motorway wouldn't be much fun lol).

Can you show me where i pushed this opinion on other people? unlike your earlier post, i was providing advice based on facts and experiences.  not once did i push my opinion of whats best (unlike yourself).

how about saving some money
when you need the roar
go in an angry voice roooooooarrrrr
then dont do it when you want a quiet ride


but on a serious note vauxhall cars are renound for screwing the sensors if you fit a kn and alike
unlike my last car please dont laugh (a mondeo v6) that had a kn71i on it ,the only difference was 2bhp so wouldnt feel any improvement,
pain in the arse in the summer because of heat soak even with cold air feed,far to loud on a motorway,but good in town
so my own opinion is fit a panel filter get the bhp without all the trouble

OK -- liking loud cars doesn't make you a chav, liking quiet cars doesn't make you an OAP ....

Not all mammals are elephants .. but all elephants are mammals .....

Unfortunately, in this world, labels stick, rightly or wrongly

Personally I like a nice, serene, quiet drive (til I get my free bus pass). Trouble is, every time I stop at a junction I think I have stalled  :-[

The panel filter on the Omega is huge for a 200 BHP engine so it offers no noticeable restriction. The sensible way to tune an engine is to modify the parts that are the weakest link first. That means the exhaust manifolds, unfortunately. It's not always the easiest bits to bolt on that give you noticeable power gains, despite what the aftermarket tuning parts manufacturers will have you believe.

The induction system will have been designed not only for low noise but also to augment the breathing of the engine at low RPM. Put a shorter intake tract on it and you will lose low RPM torque and, if the original system has been designed well, you won't gain much if anything at higher RPM on an otherwise standard engine. It's not worth losing that low down torque unless you're going to get serious gains at higher RPM by fitting hotter cams, ported heads, etc, IMHO, especially on a heavy car like an Omega.

I have to say, modifying to increase noise alone seems a bit pointless. This comes from someone who is not averse to a bit of noise from time to time. My "other car" does tend to grunt a bit but largely for packaging reasons.  ;)

Mine's a London Pride, please, and a packet of cheese and onion crisps.

Yeah that was new to me as i have never worked on a Vauxhall with standard induction before. From what i have learned on here that is caused by oiled filters, so to avoid any issues, dont buy an oiled filter (such as K&N panal filer) personally from experiance, i would recommend the pipercross foam filter.

If you really wanted it quieter up front, you could try insulating the inside of the airbox with sound deading material (avaliable from any audio retailer or from B&Q in the plumbing department for half the price). Ive never tried it on a road car but seen it done on competition cars to get the induction noise level down.

Hehe

I have one of each

My Elite is silky smooooooth and quiet.

Yet

My GLS has a speaker attachment (Busted backbox) that is controlled by my right foot.  In town it has the V6 gurgle and in full flight it sreams faster faster at me.  If I modded the intake take box I would hear it more at fiull throttle low revs, and less at high revs as the exhaust speaks volumes.  But I likes it.


Am neither a Chav or an OAP.  I am simply, me, myself and I.  I wear a few hats, it just depends on my mood on that particular day. ;D ;D


When I sort the exhaust though (Soon) I am considering a NOS kit,  I like the thought of the "Stealth Surprise"  and hearing the comment.    S**t what the F**K was that, so the less noise the bigger the surprise.   hehe. ;D ;D :y

Just to put things in perspective here's my two pence worth.

I think there's nothing better than to hear a well tuned engine or a V6/V8 gurgling away or producing a great sound track at high revs but there has to be control as to how much noise they produce. Can you imagine what it would be like to have thousands of cars howling away if you lived anywhere near a road. So, have a car that makes a great sound but within reason.

On the other hand, in motor racing at a proper racing cicuit, the louder the better. It's one of the reasons I love motorsport so much. :y

As said, it's all about getting things into perspective. :y

Agreed .. but at motorsport they don't tune for noise as the OP asked .. they tune for driveability  .. Power, response etc etc, the noise is a byproduct.

The OP wants to tune for noise, this will probably result in LESS power and certainly less efficiency.

I have my views on tuning for noise anyway, but they are not for here .. :)

You are missing my point. I just don't understand why anyone would want to mod a car simply to make it loud. I see it all the time but mostly on gutless Corsas and Saxos. What is that person really trying to say? Is it "Hey look at me everyone, I'm a  ........." or is it "Hey everyone, I don't care about you, I'm going to be a nuisance" or is it something else?

I've always enjoyed driving cars hard and I'm far from being old enough for a bus pass. Deliberately moding any car (especially a Mig) just to make it louder seems a reduculous thing to do IMHO

I like my elite quiet.
My TR4A has a 4 into 2 gas flowed manifold going into 2 big bore pipes with straight through boxes at the rear - it's quick for a 4A (mod'd engine / induction) but mod'd for power & u should hear the exhaust note!!! Noisy ;)

Forget the induction side of things. Try starting your V6 with just the down pipes on it! That is a noise that could wake the dead!!!
When I put the stainless exhaust on mine I couldn't help but start it to see what it sounded like!
Some how I don't think you'd be able to drive it far before either H21's mates stopped you (he's been quiet lately! :-/) or your ears bled!!  :o  :y  :y  :y

Not wanting to bring the thread back to earth, but I put a Pipercross panel filter on my Veccy and carried out the "3 pipe mod" and there was a "small" increase in induction noise and it felt like there was more torque. Maybe that ws a figment of my imagination though.

Now I am an Omega owner (2.5V6) I love the fact that the car is almost silent and very smooth. I have to look at the rev counter to make sure I haven't stalled it. However, when I put my foot down, it wakes up and makes a great sound that, IMO, is only bettered by the BMW straight six, or a V8.

If I were to look at modding my induction, I would look at a Pipercross or K&N panel filter that just replaces the standard one.

That is however only my opinion and in now way be-littles anything that anyone else would do.

Thanks
Mike

tbh, with the omega, replacing the original filter with something else virtually always results in lower performance across the range.  The standard filter on these (esp genuine) is very good.

As said, if people want to replace for cones etc for noise (within reason), thats a different matter, and each to their own.

on a serious note vauxhall cars are renound for screwing the sensors if you fit a kn and alike
unlike my last car please dont laugh (a mondeo v6) that had a kn71i on it ,the only difference was 2bhp so wouldnt feel any improvement,
pain in the arse in the summer because of heat soak even with cold air feed,far to loud on a motorway,but good in town
so my own opinion is fit a panel filter get the bhp without all the trouble

Yeah that was new to me as i have never worked on a Vauxhall with standard induction before. From what i have learned on here that is caused by oiled filters, so to avoid any issues, dont buy an oiled filter (such as K&N panal filer) personally from experiance, i would recommend the pipercross foam filter.

i want my v6 to be as quiet as possible, that way you know when there is a prob as the noise changes from a sweet hum to a ratle and unhopefully a clunk. :y

If you really wanted it quieter up front, you could try insulating the inside of the airbox with sound deading material (avaliable from any audio retailer or from B&Q in the plumbing department for half the price). Ive never tried it on a road car but seen it done on competition cars to get the induction noise level down.
[/highlight]

idea is ok but then its not the engine thats quiet but an enhancement? that has done it, worth considering tho on a noisy engine, what i mean is to be as quiet and mechanically made and looked after, so i know its running perfect as the factory intended :y

Just to put things in perspective here's my two pence worth.

I think there's nothing better than to hear a well tuned engine or a V6/V8 gurgling away or producing a great sound track at high revs but there has to be control as to how much noise they produce. Can you imagine what it would be like to have thousands of cars howling away if you lived anywhere near a road. So, have a car that makes a great sound but within reason.

On the other hand, in motor racing at a proper racing cicuit, the louder the better. It's one of the reasons I love motorsport so much. :y

As said, it's all about getting things into perspective. :y

Why not try fitting one to your BBQ for the lakes Bob :y...might help cook the food quicker ;D

yep, not sure i'd want an A10 living next door to me and starting up early a.m. in our little close. Ok, i would, but your right of course, its a bit selfish really.
Must be a way to have it nice and quiet low revs and Ascari A10 from say, above 5000 rpm? Anyone?

Induction side is fine, any messing is at risk of hot air intake or getting water in from puddles.

What you really want are tubular exhaust manifolds and a large bore exhaust - rather than a noisy intake

I always hate the association between modded cars and chavs... Does my head in!

Im about as far from a chav as I can be... I hate them!

But because I have a cone filter on my car, it makes automatically makes me a chav? What will I be when I change the exhaust then? A SUPER Chav?  :-X
