is it worth fitting one of these in place of standard item and if so what gains or improvement in efficiency etc can i expect?

[Marks DTM Calib]

No gains or improvement in anything although it will empty your pocket a little.

IF you are hell bent on fitting something like this then get a 3.7 Bar one for a 2.6/3.2 from Vx for less than what the likes of Regal and COurtney will con you for.

Still, surely no point in that, as the lamdas will trim back the fuelling anyway? Until the trim is right at one end of its abilities anyway...

i am a bit confused... What are the supposed benefits then if youre saying that by adding this i wont see any difference? Been offered a bosch one for a tenner so thought it might be worth a punt?

The injectors are big enough on the omega to cope with fuelling demands without increasing fuel pressure.

Why do they sell it? Because people will buy it

with addition of cams/chips the 4.0 bar FPR would be more appropriate yes?

No....an FPR with increased pressure ratings will only ever overcome a problems with injectors that are running at mximum duration on WOT.....and the injectors have loads of headroom so you will be doing well to get to that point!

[humbucker]

ah so you wouldnt do any harm by adding one, it just is designed to cope with pressure that you probably wont reach on a standard omega setup?

no point VVOC recommend them for the V6 Vectra to remove flatspots but a friend got one for his GSi and it still had a massive flatspot

your better off camming a 3.0V6 fitting 3,2 ex manifolds and then chip it & remove the exhaust centre sections thatll give a 3.0 a nice power increase and without spending stupid money thats about the most you can to do get more bhp with it

Forced insuction costs loads and as the comp ratio is fairly high nitrous would blow it to a million and one pieces i expect

[miniator]

are the 3.2 exhaust mani's that big an improvement over the 3.0s....if they are i must try and hunt some down

[tmx]

MDTM said they would improve things!

im buying some seems the avg price for them is £25 a side

the omega breaker on ebay sells em for this when i get paid ill be getting some!

they look interesting to fit! haynes reckons the engine must come out but ill wait and see!

£25 quid a side, not bad....

are you getting a RR before and after....would be interesting to see the improvements there like

ive got a before from when i had the car chipped last yr running 221 with a Collins powerchip

local car tuning centre's dyno cant do RWD because saxo's/corsa's are FWD

[markey mark]

i have just fitted facelift manifolds on mine complete with 4 g cams and 3.7 bar reg !
havnt had it on rollers yet but is a lot smoother and pulls much better !

what a load of balls....my omega was run on AWD rollers set for FWD's...ie....i stopped when my back wheels stopped on the rollers lol

@ markeymark - sounds good so far mate, though what are 4G cams?
