hiya,
just (trying to be) a quicky on flywheels..
is there any difference in weight between the 2.5 and 3.0 flywheels and also does anybody know if it's possible just to remachine the standard flywheel (i have a spare) or just buy an alloy is it? performance one off courtney (remachining is free)
thanks

[cem_devecioglu]

I remember some lighter ones special for miggy on e-bay..

can you remember how much they were roughly?
thanks

more than 100£ , all I remember sorry

[Ian_D]

How much different are they from a Vectra Flywheel? I know that you can get lightened flywheels for them, and I Seem to think there were about 300 and odd quid. (going back about 10-12 months)

[ngrainqey]

lol thanks anyway, i looked and cant see any 6 stud/vx flywheels suitable

what about heads and performance valves?

[Ian_D]

Here we go... Found it:

HTH!

I've read loads of times that the exhuast manifolds are the biggest restriction on the v6 lumps!

lol thats why im on about reboring them matey
apparently matching the ports between head and exhaust helps alot!

i'v had a nosey at the courtneysport flywheels, i have a spare flywheel so thought why just not remachine it

Hmm, Without seeing a flywheel off an omega up close its hard to say... But I guess you could loose a couple of KG's, however you dont really want to go too crazy!

A shattered Flywheel WILL make a horrid mess!

I have never undersrood the benifits of a lightened flywheel :-/
(apart from when the box is in neutral)

when revving up the mass of flywheel is important even the weight

of tires..I read something about those on tuning pages..

[ngrainqey]

lol takes less time for the engine speed to increase so is more revvy/or revs more freely!

side effect can be that you lose speed easily up steep inclines

Correct....a lightened flywheel only help an engien on a dyno........when connected to a gearbox, prop, read diff and then a 1.7 ton car....they make break all difference!

Plus, you wont take any weight off an Omega flywheel as its a complex multi piece dual mass setup!

As for the exhaust maniofld to head matching....they are already matched!

Im not quite as thick as I thought I was then.

I wondered if that was the case after I posted the above comment! Learn something new everyday

riiight.... what about opening up the ports to the exhaust manifold and matching the bore in the manifold? (obv would need sports exhaust etc to get benefit)

Interestingly, the 2.6 and 3.2 manifolds seem better.

When I have Mick Dundees car on a long term stay and fix programme ina few weeks we shall see just how much better they are.

lol i'm going to invest time money and patience in a v8 omega project but not this minute
i want to work upto a big project like that haha!
i'v thought about a twin turbo project but need to be arsed to buy two t25 garret turbos haha!

[ngrainqey]

oh yeah... from looking at a flywheel on the omega it looks rather like just a solid plate with six bolt holes in the centre and 6 mountings for the torque convertor

let me know what happens with that mark, might have to buy some depending what happens with tubular manifolds lol

You wont get the flywheel any lighter on an auto....as its a flex plate.....they rely on the torque converter weight.

some like it different

I thought that!  

How heavy is the torque convertor? Im sure my Auto Omega revs up quicker than my Man 2.5 Vectra gsi  :-/

[tmx]

its a DMF flywheel so it cant be lightened can it???

MV6's is DMF anyway i assume they all are

go on uksaabs.co.uk i think or .com
all the 9000 turbos have t25's... probs just need new bearings haha!

[ngrainqey]

might do away with the multiram, get an induction kit then bolt two t25's on
just have to find the right head spacer plates haha!
think it'll want the 2mm ones (and yes i'v been asking about to do with turboing the omega) apparently you need a piggyback or standalone ecu for the fueling

if you dont decrease the compression ratio and arrange the pressure of turbo I think you cant reach even 4500 RPM :-/

and the last thing you hear will be a bang!

Check the engine is strong enough - seem to remember its not.  I think the 3.2 has steel crank, that may help

Oh Dear, Oh Dear, Oh Dear.... Whys everything have to be complicated  

[ngrainqey]

the turbos are fine at 6psi with standard mapping...but could do with mapping better..
and it's called engine lockup
it's fine aslong as the comp ratio isnt too high so need some spacer plates unless i just intend on using it upto 6psi (which i dont if i do it right )

[ngrainqey]

..right bed time!
cya later

[albitz]

Dream of little flywheels and big turbos.
