What causes the V6 to have little power?
Ok. I've got a problem. Here are 3 cars. A vn, vp and vr. All stock motors. All done around same mileage, 300K. VN motor goes like a bat out of hell, the VR motor is nice and quick most of the time. Then comes a VP. Now this VP basically has the same motor as the other two. You put your foot down and it goes but just doesn't do it fast enough. It takes 15 seconds to get up to 100km/hr planting it. I'm not sure why. The components of the motor are fine, no leaking manifolds or low compression. The throttle body is clean and all filtrers and oil are new. Any ideas?
Thanks.

maybe the gear box is rooted ?

possibly fuel pressure. but some v6 commodores go and others fly strange i know. have tryed and take out the restrictor from the manafold. Behind the elbow.
Sometimes you will get a dud motor,even from new,then other times you will get an above average one.It just depends on how all the parts match when its assembled.If everything matches up perfectly,the engine is gonna be better than one thats got parts that dont quite match as good.Its the same with all of the car,some cars will have heaps of problems,others that are exactly the same car,will never have a problem,I remember years ago,I bought a new YZ125,the guy up the road had one the same,and so did a mate in town,Mine went heaps excellent,well above average,the guy up the road,his went ok ,but not as good as mine,then the guy in town,his didnt go very good at all,it had lots of breakdowns too,we never had any problems with ours,these were all the same models,all brand new,so it goes to show,some vehicles will be lemons,some will be better than average.This old guy I know always says never buy a vehicle thats been assembled on a friday or a monday,as most of the assembly line workers have monday itis on mondays and more than likely will do a slack job,and on fridays its a rush to finish the jobs off so people can get to the pub or home or whatever earlier..He used to swear by this. Ive gotta admit,he never had many problems with his vehicles.

300,000km on a motor that was a nugget to start with. Its never going to be epic.

i know this is going to sound strange but my vp was doing the same. replaced everything and then replaced the fuel filter and back washed the lines. Goes like a rocket now. ended up being just the filter was r/s and it was only 2 months old.
vp 3.8 lt lowered T70 turbo 38 mm wastegate running 14 psi making 253 rear wheel kw lsd 3.08 gears. tuned by delcowizard
Changed the transmission 2 months ago on the vp. It kicks a lot nicer but no power increase so I can rule the trans out. Done the removing of the bell mouth. Made it just run rough. @Brett I have heard the same thing about motors being built on Monday's and Friday's. @soop, that couldn't possibly be a reason for low power engines. My friend had a stock vn with 500,000 on the clock and it still whipped VX's and VL turbos etc.
No fat drivers here.
I might look into fuel delivery. Thanks for the thoughts guys.
hey soop commodores arnt run in till 500,000 any good drug runner will tell you that300,000km on a motor that was a nugget to start with. Its never going to be epic.

Druggies using commodores..
LOL.
That's a great way to spend your cash. If you had $500,000 cash to quickly convert to assets I doubt you'd be buying a commo.
Could be a multitude of different problems why your 3 cars perform differently...

You gotta be kidding about beating vl turbos and vx's, get ya hand off it lol

Think we found the problem with his car...

Maybe next time your mate can inform the other drivers that there is a race going, so they can go and hop in their cars. But more likely your mate is one of those guys who floors it t lights and then gets a huge smug grin on, points at other cars and laughs when they catch up at the next lights, while the other cars have no f'ing idea what the hell hes on about.

I think it's the NA V6 part that makes it slow
The mechanics never could find out why the vn was so powerful. Call me a liar then. I think I've found out how many sour grapes are here.

Maybe it was the cop chip.

lol whipping VX's and VL turbo's...You sure you didn't run a red light and they weren't even moving...
wait...no actually you mean you dragged them at full throttle revving it off at 6k and they were barely moving past 2k...aka weren't racing you.
No, seriously. Anyone from Vic heard of a car 7-8 years ago called 'CrzeVN'? Or crazy for short? The mechanics couldn't find out why the motor had so much power. One of the very first VN's off the line and the mechanics just thought it must have been built on a Wednesday. It didn't have a cop chip or even extractors or a fully sick exhaust. It was stock and it went like a bat out of hell. It's like comparing this VP to a pony and the VN to a race horse and I want to know what it is that makes that motor so fast.
and then he woke up! lol
edit; sorry but a rattly old buick stock as a rock i cant see beating a vl turbs or an ecotec unless they forgot to hit the gas pedal.
I can believe a VN V6 beating a VT/VX/VY V6
But beating a VL Turbo is stretching the truth a little.
Why are they slow?
Because they have no boost.
Donati..Whoa Green
I haven't heard of any people driving a crazy VN, but I've heard of many crazy VN drivers.

Nah she used to race down princes hwy years ago with these many VL turbos and they would ask her what she has under the hood. Her reply would be "an engine".
Extremely intelligent racing down the highway.
