Title: New modifications of my Omega
Post by Exec on 04. Nov 2008 at 01:16
So, the first modification i made recently is limited slip differential!  :)

i changed this:


to this:


i've installed the original 45% lsd from the omega b non fl



and here are the effects  ;D







and some videos - sorry for the quality - just cellphones

http://www.youtube.com/watch?v=DBFDiiFWFcY

http://www.youtube.com/watch?v=M9HQNJFivuw



Another modifiaction is an air resonator (as mantzel's one), gives some HP and Nm









And last mod - making the nivo to work properly with lowering springs - after small modification of the sensor everything's fine now - the nivo doesn't pump the absorbers so much, as there were normal springs




I hope you like it :)

awesome a man after my own heart ....i removed the butterfly in the item you have replaced to test if all is well with both body`s getting air all the time .....it worked well so ill be fabricating a new intake system soon....:)

nice car you have there mate ..... :y

with my setup it works really well tbh, the second bod normally only gets air when the butterfly in the lower assembly opens, more air is a great start to any engine mods .... :y

you get rid of all those pipes there, and this empty box - resonator gives higher efficiency of the air intake, although it becomes a bit more noisy

i really feel the diffirence after installing the resonator box, so i can say it was worth to do this mod :)

when you press the accelerator pedal, you instantly feel the car accelerating... another thing i've noticed is not loosing the power on high rotates of 5000-6000. So the engine gets enough air now, and it has more power on high rotates

I have a fair amount of experiance tuning turbo datsuns, but turbos are easy!

Just wondered why vx go to all that trouble of fitting something apparantly useless?!

Also aware that anything less than the 3.0 AFM gets confused about the extra airflow and actually loses power  :)

Just aware that A: the management seems very sensative and B: I cant afford to fix it once its broke!

I am refering to this throttle comment about only one getting fed until another valve opens.....whcih si very wrong.

The dimensions of the mantzel unit would be interesting and any details of the internals.

sorry bud dont understand what you mean there ??
the butterfly located in the air intake alloy assembly directly before the throttle body air feed pipes. you say im wrong this doesnt open permiting more air to the right hand body ?

Title: Re: New modifications of my Omega
Post by GmasterT on 04. Nov 2008 at 17:52
new as I am to this car but not to cars/engines in general, I was under the impresion that each TB fed each bank?

Also wonder why a resonator box would help, it would upset the airflow more than anything, esp since you are limted to the airflow in in the first place by the single AFM? So striaght pipes would surely be the answer?

But obviously I then question why vx but the extra gubbins in there in the first place if by removing them makes everything better, unless its emissions only  :)

i don't understand you guys too

if you're talking about this:


it opens at about 3200rpm to equalize the pressure in both pipes


another one is in the plenum, it opens at about 4500rpm as far as i remember

with the resonator, the air has about 1meter shorter way from the filter to the engine!

so imagine - you press the accelerator pedal, engine starts to take a lot of air, and for the moment you've got some underpressure in this 1m pipe...

well, if you take it out, engine will get more air, but it won't know about it - i mean, the flowmeter should notice that the engine gets more air, and it fact the flowmeter noticed, that the engine got less air, because more air was taken from the butterfly hole...

Well it shouldn't.

Inlet and air speed theory means that low down torque will help is you ahev two long thinner inlets.......and hecne how multiram works!

No.....I dont understand you at all.

ALL air must pass through the MAF.....therefore the MAF will measure all the air unless you have an air leak  :y

All fascinating, but you should get yourself some proper shock absorbers, disconnect the self levelling system all together and remove the fuse / relay that sets teh system off.

Putting lower springs on it and leaving the self-levelling shocks will make it handle a bit wierd.

I had self levelling and now I run a full MV6 suspension set up. Trust me I tried what you have done and it is cr$p. Do it properly.

Plenum looks very nice too, but it is rough with a large surface area for a reason as far as I know. (heat dissipation)

Not sure what you're trying to do with that metal box at the front yet, but have you had the engine remapped?

Love the LSD :y

yes, it's all true, and this is what i wanted to say :)

if you want to give the engine more air, the MAF has to measure it

well, the self levelling system seems to work fine, i can even say, it keeps perfect height now, the car also drives well

maybe you had old absorbers that didn't work properly...

Shorter isn't necessarily better though. Most engine developers struggle to get enough length into the induction system due to lack of underbonnet space. It's crucial for decent torque at low revs that the engine has a decent length of intake tract. Shortening it might pick up a few BHP at the rev limiter but you'll lose a few tens of lb.ft down at low revs, and in a heavy car like an Omega you need that more.

The multiram system gives you the best of both worlds. An intake tract that adjusts with engine RPM. I suspect that, if it feels faster now, it's because you have poor torque at low RPM which picks up as the revs rise. A peaky engine always feels faster than one with a flat torque delivery but the same peak power.

believe me, this multi ram suck, you would say the same, if you have installed the box!

there's no moment (low or high rpm, doesn't matter) that you have less hp or Nm, you feel the kick on low rpm, and high either
you step on the pedal and the engine gets the power immediately

of course, it's not like you had 50hp more, but there really is a diffirence after installing the box...

the only disadvantage of using this box is a bit more noisy air intake (original air filter) but with my cone air filter i found it slightly less noisy!

No substitute for shocks that are designed for the length and stiffness of springs you have on there now though. You may have a stable car at the right height in your opinion, but you won't know what you're missing until you put the right shocks on.

My self-levelling shocks were fine and are now fitted to another car.

That's the other tough challenge with intake design. The intake can be louder than the exhaust if you're not careful, and if you're prepared to live with a little more noise I'm sure there are gains to be had. Remember to keep the intake air cool though. :y

Ok I am reading this huge post and I dont know where to even start...

Has any of you ever had some course or info on Fluids and Flows!... perhaps you guys should look into that and then talk about the difference between the OEM set up and the Other design...
Car companies would love to save money in any way they can and if they get rid of that chunky valve body before the throtle plates and all those clamps hoses and connections beleive me they will...

The idea is however to create a specific flow at all speeds in order to create a torque curve that is nice and flat so the car is a blast to drive at any speed...

The combination of the valves allows for steady non turbulent flow to be created at various RPMs, and the Mantzel box has a sweet 90° bend that is absolutely NO-NO for air flow... Air doesnt like to turn at 90°...
The MAF sensor creates a lot of turublance and thast bad for flow... so they had to try to elongate the path to smooth that flow out before it hit the throtle body...

BTW Turbulance is terrible for flow.. it actually restricts flow...

The one thing I can see happening is this... when you step on it.. the matzel box has a give air volume in the chamber right in front of the TBs and with that it allows the engine to tap into that give volume of air right off the get go.. and so you notice the nice kick in the seat... but when the RPMs start to increase I be the torque curve is no longer nice and flat, it probably looks more like the HP curve...

That box I think hurts air flow in many ways... To get more air in the engine you need to increase the diameter of the MAF... and all the pipes and even the Throtle bodies...
If you are not using foced induction you can not get more air into that engine though the small opening of the throtle bodies...


I bet if you looked at a dyno chart before and after... you will see what will happen...
if you like the drivability of the car that way, thats fine...

I will post my dyno charts soon...and you guys can see how much of an improvement the Two mufflers had on the power of the engine...

A better design would be someting where the pipe comes out of the MAF and then splits into two and curves smoothly into the throtle bodies... that i think will have a nice effect on air flow...

More on that later... I got to do some more reasearch on the Mantzel to see why the offer such increase in HP/TQ ::)

yep..

turbulent flow will drop the torque values..and that 90 degrees turn is wrong from the fluid flow theory..

initially ready air gives a kick but later will fail..and the position of cone filter is wrong..Will take too much hot air.. :-/

oh yeah! there are no 90° turns for the air in the original intake! lol


so maybe the air likes to turn 180°??  ;D

im done here.... :-X


1. that's not a public road :)
2. i run the dry tarmac too, but on the wet one, the car and tires doesnt hurt so much...
3. i love to drift, its not just a kid play for me, this is my practice... i bought the lsd to use it, not to just have it...

does the air respirator make that much difference?
How much did it cost you?
Did you buy it or have it made?
Quite interested in it.

i can really feel the difference after installing the air resonator... more about it was wrote earlier in this topic

the resonator is made by my friend - the cost - almost 100 pounds

i think c30se + biturbo set would be better idea for such heavy car as omega is...

i was toying with the idea of fitting the resonator box on my mig but having read the comments about it im not so sure now,i dont doubt the comments made by the owners who have fitted them but comments seem a bit confused.im now thinking along the lines of a large shield around my cone filter and a large cold feed direct to the cone instead.i do like the idea of junking all that  pipework and having a shorter straight route of air to engine just dont want to go to the trouble of making and fitting a box to find out it dont change much.

tbh, i would scrap the cone, get a panel pipercross/k & n filter, and have a direct air feed.
I had a cone and heat shield on mine for a couple of weeks, it makes the car feel like it is being suffocated.
I have the air resonator, i can answer any questions, it does make a difference, but if your unsure, i'd just keep it standard.

Well thats why in the winter your car typically makes more power...
You get colder air, which means its denser and the computer compensates with slightly more fuel and the result is more power...

You can easily gain 4-5 hp form that especially on a nice hot day....


Looks awesome bud!

Ok, it's time to make some updates to this topic :)

1. I've painted the roof and mirrors to black with blue & purple pearl, imho looks awesome :)












Another mod is double twin Irmshcer rear pipes






I have replaced the dual mass flywheel to single mass flywheel (from Vectra V6) and lightened it to 9kg (stock about 15kg), also i needed to use vectra's clutch disc (with springs).








Title: Re: New modifications of my Omega
Post by Exec on 20. Jun 2010 at 16:14
Bored? Time for some modding! :)




Newer type oil cooler




3.2V6 version exhaust collector = getting rid of EGR and catalysator heating system, all those pipes, pump, valve are removed. At last! :)




Occasionally some new stuff :)




And some cleaning...












Little 3.0 pipes mod for fitting 3.2 exhaust collector






Vectra V6 alu covers, painted orange, soooo orange :)




Engine almost ready






Done :)

Very very nice project! I like people who are brave enough to try new stuff.

I see you're using a DBW plenum, but you have modified it to take an IACV and EGR system. How did you fit the IACV? I have a spare DBW plenum that I'd like to fit on my car :)

Yes, Drive By Wire.
It looks like a modified DBW plenum. Motor-box for butterflies opened and a remedy to fit cable. Or did they produce a long plenum with cable too? Anyway, I was surprised to see an IACV on the long type of plenum.
Oh, on second sight I see it also have EGR fitted? Hmm.. For some reason I can't find that plenum on EPC, neither have I seen one like it - that's why I wondered if it's modified.

This is stock long plenum fitted on facelift 3.0 coming with IACV, EGR etc. (motronic 2.8.1)

The EGR is no longer used, because the exhast if fitted from 3.2 - no EGR, no cat heating system. The EGR is just connected to the installation to avoid check light flashing.

check the video:

BMWs with LSD and from 1:55 my miggy few years ago without LSD having problems with some full donuts over the cone...
Can't you see the diffirence?


Now take a look here at 1:35

Mine is a 3.0 on a 99 plate, long plenum. Is there any advantage/disadvantage to having a short plenum fitted, is one better than the other?

(have both, will fit the better one)

hm, afaik the long plenum is better...

but the mantzel resonator box was created for the short plenum, so it is possible it will give better performance with the short plenum, than fitted on the long one.

Another thing is the resonator box is easier to fit on the short plenum...
