You could always fit a rubber crankshaft, which increases the compression ratio as the revs. build up.

A mate of mine has a Westfield that used to do a quarter mile in the 9's. That's got an automatic box in it... So it can be done.

It did have a 5 litre Rover V8 with nitrous at the time IIRC, and about a ton less weight than an Omega.

Never found out how much power it had. It didn't like rolling roads much. Kept making a bid for freedom whenever he tried a run.  :o

Only time I could find with a quick search on the web was 16.7 seconds @ 102 MPH for an Elite.

I'd say that's probably about right.

Edited to say: Not sure if that's with an auto. box though!

 HAHAHAH!! ;D ;D

What i have done to improve it was you need to lighten it up.  It is a very heavy car.

Even the manual 3.0 is not a quick car by any means. It's OK on the road, although a little sluggish off the line due to weight and high gearing, but certainly no performance car. Great motorway muncher though, as the weight is less of an issue and aerodynamics are pretty good.

If only GM hadn't dropped the 4.7 V8 6-speed Omega that was prototyped -- sorry for bringing it up again ::) :D

Cheers everyone, I think i will be going for the Foot brake technique, sports mode and prolly some high octane fuel, and hope for the best! will let you know what she does!!

Am I likeley to damage anything holding the footbrake while flooring it? if so I might just let it do its own thing! dont wanna come all the way back from Santa Pod on the back of a low loader! hehe

Cheers

From experience - you should get around an 8.9 in a 2.5 / 2.6 auto, 8.7 in a 2.5 manual & 7.7 in a 3.0 manual.

The BIGGEST improvement can be made by NOT having a full tank (run just above the red), empty the boot entirely including the spare wheel and don't have a passenger. Also tyre pressure at the high end of normal.  The tip of brake on in 'D' + Sports mode does work - but just have it throttled up a tiny bit. PLEASE don't be tempted to drop it into drive - in clunk is terrifying & the potential cost implications / embarrassment would literally be priceless.

Higher octane fuel won't make much of a difference to be perfectly honest - but it's a relatively low cost 'try it out'. Also ensure your air & fuel filters are in good order.

All that MIGHT shave 0.1 to 0.2 seconds off a normal time!

Anyway - all the best!

7.7 from 3.0l Auto without trying too hard.  I would say a good .5s better for manual, more if you 'try'
