Title: performance?
Post by: jasovanooo on 26 December 2013, 19:29:52
out of interest what sort of performance should I be able to see from a 3.0 manual omega?

only im only averaging 19mpg witch is pretty ridiculous for the slowest car ive ever owned... keeping up with traffic seems laborious tbh

im hoping its just not running right and some servicing love will see it right

I'm also getting those sorts of figures from my 2.6 at the moment ?  :o

Guess having the heating on full, lights on etc don't help tho...........  :-\

Think I need to get mine serviced too  :y

I have a 2.6 2001 manual, always get around 30 mpg on my daily commute of 54 miles . If used around town about 22 mpg, on a decent run I have seen 33 mpg & I don't hang about !!

Something wrong there (or else all your previous cars have been a bit special)

nothing special really (2.0/2.5 cavaliers mostly before the saabs) I don't expect it to live with the saab (300+bhp and lbft) but this thing is gutless (considering the engine size/ economy)

high mpg and sluggish performance suggests a misfire.  Check the plug wells for oil, if present you need to do cam covers, breathers etc.  I would also look at your dis pack which is at the back of the passenger side cam cover.

Depending on what you have been used to of course it may seem slow (to say a bmw 540). routine maintainence is key to keeping performance at its best, especially good quality regular oil changes. A comprehensive service should see a different compared to a neglected engine.

been reading a few posts and a few people seem to mention this dual ram setup "at about 4k" I don't feel anything at those revs ?
the little vacuum thing on the front of the inlet moves but other than that ive no idea if it works

my old 9000 was around 370 and the current 9-3 is circa 330 or so (currently having the 2.0 removed and 2.3 fitted for better spool/ more torque lol) aiming for a little over 400 as the engines start to struggle in the 450-500 region...not to mention the gearboxes become service items  ;D

im in no way expecting it to even come close to the 9-3 but I expected it to be similar to the 2.5 cavalier (more power but also more bulk)
if the omega had a decent gearbox the spare 204r would be fitted (as far as I can tell the gearbox's are pretty much maxxed out on the v6..)

what sort of mods you have done to take up to this power
Title: Re: performance?
Post by: jasovanooo on 26 December 2013, 23:01:39
turbo technics hybrid td04 (garret wheel in a td04 body iirc similar to 19t)
3 bar map sensor
630cc injectors
3" downpipe/exhaust
forge dump valve
sachs uprated clutch
t5 suite for the mapping

everything else was stock engine wise

as to the car above how much can the r30 gearbox take? (and what box do I have on an x30xe?) do they last or is he changing them on a weekly basis lol

how would the r28 hold up to 300ftlb/400nm or so?

thik will take few track days with this power  :y
do you have any plans for it?
maybe saab b234 conversion??
Title: Re: performance?
Post by: jasovanooo on 26 December 2013, 23:32:41
well my 234 is going into the 9-3 but that will leave me with a 204 doing nothing (think ive got a 19t sat around somewhere aswell...)
id have to do something about the sump (would starve under acceleration in rwd setup as they don't like long right handers as it is)
I can see this being a moneypit lol

guess it all swings on how well the v6 runs when I find the fault...

If it's flat, the multi rams aren't working properly... there's a guide about them here somewhere :y

Not feeling anything is a good thing, shows its working.

No Dual Ram on Omega V6, but a multiram instead

symptoms are low mpg and gutless power.  Multirams wont affect them that much. As said, I would be looking at ignition efficiency (misfire, fuel delivery, etc)

Worth checking that the back box hasn't grown a tail. Quite common for the stuffing to escape and block the exhaust.

Ah yes, that had escaped me.  But a possibility.  It doesn't always show as it can collapse internally and block the exhaust (creating high exhaust pressure and thus affecting combustion) 

As a guide, here are the things to check (in order of ease):

- exhaust blockage (have a look inside with a torch or put hand over the exhaust outlet.  At idle, when the engine is cold you should feel a distinct yet slight and regular pop in the exhaust gas. if you know someone with known good v6 miggy you can compare the 2)
- check multirams are working (both at the front trumpet and the rear of the plenum, many require scuttle to be removed)
- Check plug wells for oil/water
- change fuel filter if not fairly new/unknown age
- Check/replace HT leads (with a decent multimeter you can check the resistance)
- Check/replace plugs (check for pitting/damage/wear)
- check/replace DIS pack

If you are unable to do any of these I am sure there is someone nearby that can help :y

As an idea why don't you test the performance if you're unclear on it's speed. Do a 0-60 test.... if way off the time then you got a problem. If just off do a service and repeat. If bang on... no problem  :y

What do you guys think to that test?

clutch would never take it!
its neck and neck with a Passat 130tdi if that helps lol

Unscientifically (with a stopwatch), my 3.0l auto manages 0-60 (on speedo) in 7.3s. Given the nature of stopwatches and speedos, I suspect thats a reality of somewhere between 7-8s. I'd expect a manual to easily shave a good 0.5s from that, maybe more.

I'll have to borrow some equipment one day....

;D 0-100 might be a fairer fight :-X Either way I think my clutch could take that challenge...

my old 3.0 manual would take on ep3 civic type r's and easily put a standard one in it's place.
