Top mounts are probably gone (look for sagging in the engine bay on the strut towers), and caster bushes.

If you've got the car for a test drive, give me a call at the Penrith workshop and I'll throw it up on a hoist and check it over for you :)

I'd also lookout for the fact there is no ls1 in the engine bay ;)

Thats a pretty valid point , that would make it even slower :eek:

Engine mounts are a weak point on these, but that's a roadworthy item anyway.

Also listen for any rattle in the blower, the couplers do tend to chew out over time but I wouldn't expect it at 70K. It's no real problem, but good barganing ammunition for a good deal lol.

the car is stock standard but what about one of those 10psi pulleys? Cause issues with them?

They're a great light to light street fighter with a few small mods, but they hate to rev and sound shocking doing it.
Like what what KAL and V2 said, these things have very few problems with them.
if you do get one, dont go crazy with it.
A 10 pulley to up power + a HSV cat back to make it sound a little tuffer are all you really need.

an auto supercharged v6 should pretty much hold off a ls1 stock auto between a set of lights.

The ls1 seems to be a little lardy on take off but builds a nice head of steam.

The super6 seems to bolt away off the line but doesnt do much up top.

All in all, i think they are similar.

me and my mate bought cars same week me vy sv8 Auto Him VX SUPER6 Auto
he has never one a race against me, i always win both stock door to door off the lights then i would pull away after couple of gear changes then we both did preety much same mods both with hi stall etc... and i smash him to the point were he went and spent more money to just get closer to me and watch me win. so he cracked it sold the car and bought a ve ss witch has bolt ons and now he wins..

Im looking to buy a VY Supercharged V6 for wife. It has 70,000km. I already have a VY SS.

I have a few questions.

1. I noticed that the brake fluid resourvoir was extremely low. Ive never known a car to use brake fluid? Any idea what may be wrong?

2. Any other known issues with supercharged v6 drivetrain?

Thanking you in advance of your reply

Bill

They get the same problems as most V6 commodores. Engine and trans mounts, caster rod bushes are a given sooner or later. At 70000kms you will be laughing. I have a VYII L67 Calais and it had absoloutely no issues while it was stock. Once I did heads and cam, built box and diff it all started lol.

Should have left it with a 10psi (87,,) pulley with a cat back and diff gears. They haul off the line in that guise but if you go any firther than that it will never end

What, from the lights on one side of the intersection till the lights on the other side of the same intersection? :confused:
You should try it with an ls1 with a limited slip diff and try to not wheelspin. :jester:

That would likely be worn brake pads, as they wear the fluid level drops in the master cylinder. :)

Meh each to ther own. Personally I like them, they're under rated and you're always the underdog which leaves some V8 owners with red faces when you beat them.

I sold my VE SS for an XU6, so I'm not biased like someone who has only ever owned a l67 or a bent 8... I respect them both for what they are.

A VY super 6 with 70,000 km should be pretty good thing, my brother in law has one with near 300,000 km on it, still going OK (02 Calais). If your not sure about it, take up Lukes offer and get it checked over. Brakes might be as whitels1ss said, but it may have leaky master or slave cylinders. Shouldn't be a deal breaker, but you might use it to bargain the price down a tad. I just sold my 13 year old VS V6 about 2 months ago 150,000 Km all good, I did have problems with rear main seals years ago. I think the Ecotech from VS to VY is pretty durable thing. I have more confidence in Ecotech than the alloytech.

Why does every single thread relating to the S/C 6 have to become a S/C 6 vs V8 thread. Grow up kiddies. :rolleyes:
Having one in the family (plus experience through work), here are the main things.
Engine mounts (same as regular V6).
Rocker cover gaskets leaking oil.
Rear main seal.
Oil level in supercharger, as front seal on snout tends to seep a bit.
Ignition leads breaking down.
Fuel gauge inaccurate.
Plus, usual Commodore things like diff pinion seal leaks, front strut top bearings and mounts, leaking steering rack and pump, diff whine.

I drove it and to be honest feels just like a v6? Just a little more urgent. Car feels solid, good steering, its quiet and gearbox feels good.

I was reading stuff on v6supercharged.com and some of the claims... (faq section)

"almost will always be ahead of a gen 3 to 2\3 of the uarter mile"

And

"will always beat a gen 3 from traffic light to traffic light"

I have a vy ss, will my wife be bolting away from me from the lights?? Lol

The best advise I can give about an L67 is to never EVER return to that site, read his dribble or purchase anything off him!

L67torque.com for all the honest info you can get :goodjob:

Hehe you'd be suprised I've only been passed once in mine (modded) to a cammed up cv8 and that was at speeds I dare not speak of.

Some other problems are the LIM gaskets - lower intake manifold under the supercharger. Thermostats are common and head gaskets also. 70,000kms isn't bad but be prepared that this is the period that some problems start coming up on them.

Blown V2

10-09-2010, 12:38 AM

Head gaskets a common problem!? Can't say I've seen any let go without it being fault of the owner (neglect, or pushing it too hard)
You are correct on the LIM gaskets though, look for a thick brown build up under the rad cap.

Sure they are a bit slow as standard, but they're quite responsive to changes like an 87mm pulley.

Just goes to show how strong the 100% stock bottom end is.
Granted it needed a 2.9L blower to run the 10 ...

Funny how a thread asking about a car for the wife has turned into a performance thread AGAIN. Yep, this site is MUCH better than L67..:rolleyes:
OP, is this a major priority, or are all these "experts" just blowing hot air out their @rse?

Pulled the motor out of the car for the first time in its life 6 weeks ago , mainly to paint the bay after being smoothed.
I havnt cracked a bolt on the bottom end but I did find a piece of timing chain tensioner in the oil pick up that was blocking 30% of the screen , placing it back on the tensioner it would seem its been stuck in there for several years going by the wear difference.

My engine has been detailed and still untouched to go back in when bays done , see how much longer I can beat up a stock bottom end before it melts , cant say I havnt tried so far :eek:
The only difference now is a double row timing chain and deleted balance shaft.

Given mine has 150,000km on it and it now runs 13-14 psi into the motor on a stock bottom end after 5 years of my punishment is testimate to how strong and relaible the engine is.

Granted times arnt going to make a difference to mrs buying the car but the motor in stock form wont even make a sweat ....

the guy with the supercharged v6 vy agrees with me on a price, then im waiting on the car details to do revs check and organise an inspection, he doesnt give them to me, then he sms me and says he has to go overseas urgently and cant sell the car?

Why advertise it, agree on a price then do a backflip? Maybe my inspection was going to find him out?

12-09-2010, 09:33 AM

Yep, im willing to bet if you called up pretending to be someone else it'll still be for sale. Probably got finance on the car or something...

Anyway...

The super6 is a nice engine, but they do use a fair bit of fuel. Personally, i have found the Super6 pretty quick at take off compared to a STOCK VTII/VX LS1. 0-50 is faster with a super6, but after that its game over. Thats partly due to gearing, and the fact that the engine has a perfect power output for full throttle starts. I find the LS1 (with an open diff) will wheel spin off the line with full throttle, whereas the super6 wont. So its easier to get it to 50kph quickly.

Any modifications to the LS1 will completely change that though. My dads WHII statesman (Super6) gets around 14-15L around town. On a run to Sydney we got it down to 10.5L/100km. So just be aware they will use a fair bit of fuel. A economically tuned LS1 should give similar fuel usage with a little more power on tap.

Like most cars, it just depends on the condition/price etc

If you are just looking for a nice VY for the Mrs as a daily, just keep your eye out for a VY II S pac atmo. It's getting harder to find a really good original one, but they come up from time to time. Maybe a Berlina is a pretty good thing also. You can do the REVS check yourself on the web - need the VIN number and engine number Rego number - read them all yourself on the car write them down, do the check. Pay for the certificate if you feel more comfortable having that. Who knows his overseas thing might be genuine, sounds like he has basically ended the deal? If so, walk away, find another one - getting hard to find VY's with less than a 100,000 Km now. Wwas the car an S pac?

Bingo BIlly

12-09-2010, 12:41 PM

it was an s pack supercharge.

Anyhow im not fussed on the Vy. Ill go VZ, VX even, I just want a mint condition car with something a bit extra than the ordinary version. ie supercharge V6 or LS1 etc etc.

I might even consider XR6 BA

Our +300,000km S/c VT Calais is still returning avg. 12's and low 8's on the highway on reg unleaded...

14 - 15 l/100 km round town is about right for say Sydney traffic, I had a VY Exec wagon for work when new in 03 to 06, and 14 to 15l/ 100Km was pretty typical, as is something around 10l/ 100km on a trip. My Ls1's do about the same on a trip, my LS1 '02 VX Calais gets about 16.7 l/100km around town in Sydney peak traffic.

Dont the Super 6's only run on premium unleadeded? It might be worth considering the extra cost of fuel compared to running something else on regular unleaded

Yeah, I think technically you are right, but my brother in been running his on E10 for at least 2 years, doesn't seem to be a problem, no doubt power is down, but it runs fine.

Ours (VT) has been running on RULP for years, pretty sure PULP is only a recommendation. Engine and exhaust are all stock, gets regular services - it's definately not the serviced every 5000kms car thats for sure. Major repairs thus far have been, engine mount, 1 pulley (not on the charger, a shitty little plastic thing), ABS module, shockies all round (age), had a bit of diff bounce early on and the steering rack - oh, and chews the back tyres. Sunroof is still going strong, I prefer the seats for comfort over my VE.

the guy is a bit sus.. He agrees on price, then his ad disappears off carsales then two days later he backs out?

I was getting a little excited, ready to order a 10psi pulley. Plenty others for sale but im very picky, want a low km, mint condition car. Ill pay a bit extra too.

I don't know if it's the same one, but there is a purple VY S pac super 6 with 70,000Km, on Carsales ad says last modified today 12th Sept., overseas trip etc. if it's the same one, the ad has been placed again, or modified today.
