1)
Is there a way to improve engine plenum on a omega 3.0 v6?
Someone has told me fitting a Saab 3.0v6 Plenum will help increase performance.
(or would a Vectra one be better or any other?)

2)
Also, Would forcing the multi ram to stay open (but clipping it open) increase performance.
or
Would by-passing the Muliram system and connecting the throttle body via a pipe to the air box increase performance?

1) I think you'll find they're the same

2) Don't you think that Vauxhall would have done that to start with if it was better

Is the 3.2 plenum any bigger/longer/better than the 3.0 or are they identical ? :-/

identical ...... apart from no EGR fixing point and DBW throttle

Cheers Andy - I lie awake at night full of curiosity about these things.

I think the fixing points for the cable throttle & DBW are actually the same ................ I was being pedantic

You meant no EGR and no ICV

Ultimately Raj needs to accept that he drives a 1700kg car that is never ever going to be a sports car!  even if it does have a spare pedal

Indeed... If he wants to make it quicker, start with weight loss

1) No

Both the 2.5 Vectra and the 3.2 Vectra have different plenums to their Omega counterparts, though on the Vectra, this is a compromise for space reasons.

I put my mig on a weighbridge today, no load in the car but 3/4 full of go juice, it tipped the scales at 1860 kg ,no wonder it likes a drink

raj make up a new direct air flow path like a mantzel resonator , i did to mine made a great difference , alto no one on here will agree with me because they like slow slosshy migs , vauxhall never intended the majority of things that people modify on cars , also cut the cats out of it , another nice gain , also i put on a light weight flywheel and that has made the best difference of all , it revs no bother now up threw all the gears , totally different to drive now much more acceleration out of it , next im going putting the mig on a diet and losin some weight , go for it m8 im sure vauxhall didnt intend what i did but they really should have lol
