Not convinced you'll see much performance benefit from modded intakes....

There's on way to find out  

[TheBoy]

Absolutely

[Admin]

Sorry guys, I think you need to remember that to increase performance from increased airflow coming in, you also need to shift that increased volume out the other side!

Take a look at your exhaust manifolds. If you want to improve performance, change them, they are far too restrictive.

Oh and if you find a quote that doesn't make you shudder, let me know!

Why do people keep talking about increasing BHP or torque by changing the flywheel?? Obviously there will be no BHP increase, the flywheel has NOTHING to do with the amount of power the engine produces!! It's merely an intermediary for transfering the power from the crank to the clutch/gearbox/drivetrain. As previously mentioned, dropping the weight of the flywheel means the inertial forces on the flywheel are reduced, thus allowing it to 'spin up' a lot quicker.

As for damaging the engine, it wont. Yes it'll be a lot less smooth, revs will drop off quicker, shock from the clutch will be felt a lot more etc But imo the drop in the amount of shock being absorbed by the flywheel wont be anywhere near enough to do any engine damage. Most of the shock will be felt by you, not the engine.

The main point that i'm highly considering is that the Omega is a very heavy car and a reduction in flywheel weight may not be hugely noticeable, it would be a lot more noticeable in a lighter car. There will be a small improvement pulling through the revs, but the loss of momentum in the flywheel may make hills (or carrying a lot of weight) not much fun....

Dave,
the standard manifolds are not as restrictive as people think they are due to the firing order of the engine being 123456, you get enough time for the engine to create negative pressure waves that will aid the the gasflow. For example the 1, 3, 5 sequence causes 3 sequencial waves think about it. I'm sure that if someone would set up a model on WAVE there would be no issue flaged up. Yes it would have been  better to have nice and smooth headers but thet are not necessary unless you want to achieve 100hp/lt.

Well this weekend, I'm going to barstardise my intake System... I'll let you know you how goes.

Also on a slight tangent... how do I clean the Engine Bay?
On my landy, it was simply, drive to a car wash, pop the hood and get spraying while the wife held the throttle at 2000RPM..
But with the 'meega's sheer amount of electroinic wisardry I would't dare.
See I have a leak but can't find the source, so I figure cleaning the engine up a bit might show me where it is comming from, pus it's a right state under the hood anyway...
Suspension- Any good makes people could recommend, that work well at lowering and stiffening the ride up a bit?
I already have the EBC Discs and pads put on. (did them when I changed the wishbones.)
One final thing..... as every boy racer knows graphics on your car, gain you 50BHP, maybe 60BHP if the graphics reads "TECHNICS". Whatever they are....
I was thinking of getting mine done in the touring car colours of the old Vectra, you know the white and yellow scheme. (At least 100BHP more).
Cos I really would quite like to use the Omega for Castle Coombe track Days, and I thought cool Graphics would make it look the part.
Anyone know of a good reputable company that does this kind of thing. Thought I would ask here first instead of randomly calling companies from the internet.

Cheers.

Matt,

It would appear you and I are at similar stage re bastardisation and oil leeks.

I am in the same boat re cleaning the engine and apparently a good soaking with gunk does the job then either very carefully jet wash it with electrics taped up or hand wash it.

My leek seems to be coming from the rocker cover gasket. I found there was oil beneath the HT leads which means it can only really come from one place. Apparently this is very common on V6's. It took me about an hour to get the intake manifold, ali casing and rocker cover of for the first time and I am no expert to might be worth checking it out yourself, or you can just pull the HT leads out and check for oil.

Re graphics. There are a number of methods of producing the graphics. If you have complex colours with fades in you will need to get the graphics "printed" which is more expensive but better quality. If the graphics you are getting are all block colours you just need to get the colours cut then layer them. This is cheaper but you have more chance of them coming off as you have more graphics. Just a thought you might like to bear in mind when getting quotes. If you need any help with the images give me a shout as I'm quite handy with illustrator etc.

Best of luck.

Look forward to hearing how you got on over the weekends.

How did the bastardization go?

Check the Post Entitled... "Air Intake Barstardisation"

I thought I would start a new thread, as it's kind of a new Item...

Oh, also the wife is going to murder me!!!!!

I have just brought... : http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&ih=012&item=220020144956&rd=1&sspagename=STRK%3AMEWN%3AIT&rd=1#ebayphotohosting

Hell I need that before I graphics applied....

Thats my excuse anyway.

hi guys, can I pick up onthe old flywhel thread.  A lighter flywheel transforms the v6. True it doesnt make any more power but a lighter flywheel means that less power is absorbed in accelerating the flywheel. That saved power is then available to the wheels. Check out Puma race engines site for all the tech stuff.  But if you do nothing else change the flywheel. you will be smiling. ps it doesnt change the torque at all, and hill climbing is not effected. acceleration will be dramatically improved in the lower gear so at the end of the straight you will be going more quickly.  its only physics.  Regal and chris astley can help with direct replacements flywheels or the xe option but I dont think the xe is a direct replacement, particularly for the dual mass.  have fun

.....  its only physics.   .........

So is the 1700 kgs of Omega!  :-/

1690kg's if youve got a light flywheel   lol

Has anyone done this yet? ill be changing the clutch in mine in a few weeks and will be looking to do this at the same time. any info would be greatly appreciated.
