I have a 1996 3.0 v.6 omega elite and I was wondering what is the diffirent's between the grey engine plenum which is fitted to my car and the engine plenum fitted to later cars which seems to be longer and more curved and shorter hoses to connect them, does it make a diffirents to BHP

[Kev]

It means mine's is bigger than yours.

It's not just the plenum that's different , they are bigger engines - 2.6 and 3.2. They are also drive by wire so they don't have an accelerater cable, and they don't have an idle control valve so they don't need to have a squarish front

Sorry, thats not quite correct.

My 1998 MV6 3.0 has the elongated/droop plenum.  It came in, I think, at mini-facelift, and across the engine range.  And mine is old style cable (and cruise), not fly by wire. 

Someone else more clever than what I is will no doubt explain better why....

Droop snoop fitted to post mini facelift 3.0/3.2 engines...

I stand corrected. I've only see the drooping plenum on the later engines (2.6/3.2). Is there a pic of yours anywhere so that I can see what it looks like and where the ICV is placed?

Mine's is the facelift with the 3.0 not the 3.2, and it has the extended/drooping plenum. Still has cables for accelerator and cruise.

I've got pics on my home PC, but i'm down South at the moment. If no-one else posts a pic, i'll do it for you when i get back home.  

I think the question Jim wanted to know is whether there would be any benefit in changing the setup to the same as mine as he too has the 3.0 but it's pre-facelift, with the shorter plenum. Better performance/torque?

These picture's are also borrowed from eBay they show a 3.0 v6 similar to mine;



you can see who it differ's from the later 30.v6, but I beleive that both engine's are x30xe's is this correct?

So what's the diffirence? more power?

Thank You Kev for making my question more clearer, it's good to have a Fairy God Mother looking over me

Sorry to distract everyone fro the original question - I can't answer it though. I did find the pictures very interesting. Only the old one had cruise control fitted and it didn't have that second aux water pump.

Both engine's have cruise control, it's just fitted further forward next to the inlet chamber's

[TheBoy]

No difference to cruise fitting as stated, just slightly further forward due to longer plenum. AFAIK, no difference performance wise, and seeing as only fitted to 3.0/3.2 probably just balances the intake on the larger engines a little better...

I can't see the second cable for the cruise control. I did find a pic on eBay of one where I can see it and it doesn't have the second aux pump but I don't know how to post a pic.

If its a 3.0l and there is not a 2nd throttle cable for cruise, then the car doesn't have cruise!
