Hi guys, hope you're all well.

For some time now I've been looking at ways of improving the acceleration of the old girl (the Omega that is  ) and I'd like to share with you a list of things I've done and potentially some ideas to get it even nippier off the line.

I was told ages ago not to listen to 0-60 times as they are, well, complete 'dangle berries'! I now agree with that. I swear the times in Parkers and the like are simply made up as they list my car in exact same guise as 9.5 seconds and 9.2 for the same engine and spec 

Anyway, a while ago I went to TB's (can't remember what for) and he drove the car and his verdict was it felt a bit underpowered. knowing he always drives like it's stolen I knew I had to look at that further.

The problem, after many hours on the forum, was found to be a duff vacuum box at the front. Got a new one and it really seemed faster. Was very pleased,

Anyway since then I regularly check the vacuum lines, the operation of the multirams, I've checked the vac lines are in the right order as it's clear that's very important. I've done compression tests (all spot on), I've replaced ht leads, coilpacks, replaced cam covergaskets when theres been a load of oil in the wells, ive kept the breathers clean, changed a faulty crank snsor, etc etc.

I'd say the biggest thing I've done to affect the performance though is to actually drive it fast! clearly theauto box haspicked up my ''new'' style of driving and it feel really quick. im enjoying that.

anyways, ive been considering a chip for some time but to be honest the price well exceeds the gains after reading peoples reviews so im not going to bother.

this may sound a really retarded question.....but ive got budget tyres on all 4 corners. and they're pretty much all nearing replacement (3 are on 3mm and 1 is on 2mm). would buying a decent set of tyres improve the acceleration? would the low-ish tread take away any performance? would anything in the suspension set up affect acceleration?

your thoughts always welcome.

Physics would suggest worn tyres produce better acceleration than new ones

[Webby the Bear]

interesting.

ill have to bring it back over to you tb... see if you can see the gains ive seen

ps, ive said I don't want a superhips remap. but do they do one of those Bluefin plug n play things for the omega? out of interest

[tidla]

Seem to remember when Top Gear fired one over a quarry edge it went rather well with gravity an all.

just answered my own question looking at their site....no, the Bluefin isn't available on the omega

It is, or was, but only for Flash Memory Map ECU's, ie DBW's only (excluding 2.5TD).

Forget BlueFin anyway, most people I know don't rate the Map improvements anyway.

thanks zirk.

I think most on here agree that a remap via the superchips is a bit of a waste of time anyway. its a lot of dosh to get nothing out of it. though the website informs me ill get an extra 12bhp and 16 torques. oooh what to do

thanks zirk.

Just hold fire on the Chipping Webby, my Chip man is still working on the 2.5 Chip.

[Webby the Bear]

thanks zirk. let me know if theres anything he can offer. ill wing some dosh and beer tokens to you   

[Webby the Bear]

ps im sure its been covered but would there be any engine risks of doing a remap? and I could still keep my egr blank?

[Webby the Bear]

so. just coming back to the original post.

if I do all the things as per the first post yet im still getting a 0-60 time of around 10.5 seconds.....as oppose to the book time of 9.5....even though I don't trust this.....

what else can I be doing to get this down?

or is the parkers time near impossible to gain as it is just a pure lie or they did some ''things'' to make it as good as possible (i.e. took seats out for example)

[JamesV6CDX]

3.0 cams?

3.2 Exhaust manifolds?

3.0 droopy plenum?

Porting?

[Webby the Bear]

thanks james.

I kinda meant is there anything that can be done to it in its current 2.5 stock form...

or another way of putting it....

why does the 9.2 (or 9.5) second dash seem way off as I cant do better than 10.5 (ok its only a second but still) when ive done all the things I can to check the health of the engine as it stands.

or even another way....

how accurate (or plain wrong) are the parkers / reviewers 0-60 times?

I've got a spare can of Nitro Methane some where in one of the spares sheds, a 10% mix should give a 'temporary' kick in the ass,just before your engine lets go in a big way the bigger the percentage the more spectacular the destruction   Can't beat the smell of Nitro in the morning
