Very Nice Senator! Interior is schmick as !
Thanks mate and as you know it's pretty hard not love HSV VZ's.
hi just wondering what the purpose of the catch can is??
All engines produce pressure in the crankcase when running and this forces oil mist out of the crank case "blowby".
For emmission reasons this blowby cannot be released into the atmosphere so there is a system for sucking this blowby back into the engine through the Positve crancase valve "PCV" but as engines age this blowby is too much for the PCV and some of the mist is force back into the intake tract which is supposed to be the clean air intake for the carnkcase.
The catch can goes into the breather line to catch this oil and stop it getting into your intacke where it can dilute your intake charge and in some cases cause premature pinging "detonation" which is bad for the engine.
Hope that helps.
Took me a little while to understand , but sure makes much sense now.
PWR auto trans cooler fitted.
Just fitted a PWR automatic trans cooler kit and it was so easy.
I've had it sitting on the shelf since before summer and only just got around to fitting it.
Hardest part was separating the quick connect from the passenger side tranny steel line using the tool supplied in the kit.
The kits come stickered for VY1&2 but you just flip the cooler to face the drivers side of the car in a VZ, everything else is the same.
Here are some pics.
First 3 shown in situ bolted to factory holes already in rad support panel.
Also showing position of DUS intake IAT sensor .
Top radiator tranny connection with tail fitted then with hose connected.
The position of the quick disconnect that needs to be removed, the R one in the pic
Finally a shot of a new badge I fitted to the front grille, not sure whether I like it or not.
Very clean looking car mate, The Senators look mint. I love that Blue with the cream interior - Defiantly gives me inspiration for my next project.
To top it off all you want is massive sound system now, With x2 15's thumping away in the boot
Mate on another note, Interior lighting in those cars. Do you have a switch in the center console that controls all the interior lights? If so is it a dimming one? (You can PM me if need be - Just i am modding my interior lighting and need some info)
Makes me want a Senator when I grow up and no longer require a ute for work. Mint
man this is one sweet as car, looks mint as, nice job
Whats with the 307 badge? Mines only a 297.. jealous and upset now lol
Well its like this, the VZ LS2 was advertised as 297kw using old dyno std, where as using the newer "din" std that is used these days , it is actually 305kw with stock cast iron exhaust headers fitted.
Ford has been using the din std for ages which explains why their cars with similar kw's were never as fast as similar Holdens.
Ok back on track, the VE LS2 is rated at 307kw using the newer din std and HSV extractors (instead of stock cast iron headers).
So I thought since my car has extractors and ballistic cats fitted it is definitely more of 307 than a 297.
Just to give it a little authenticity I affixed the VE LS2 307 plaque to the engine bay plus bought the 300 badge from the VT-VY GTS, removed the 29 from the car, removed the last 0 from the 300 badge and using the cardbord surround as a template fixed the 30 in front of my 7.
I also purchased a 297 badge for down the track in case I want to put the car back to std.
For an explanation of the kw figures go to the HSV website:

June 2010 update:
Just purchased some brand new Koni sports rear shocks off a LS1 forum member and all I can say is they are great.
Nice smooth ride when on Soft setting and handling tightens up nicely when on Firm.
These Koni's replaced The New style Monroe GT Sports which also had a good ride with HSV Senator luxury springs but seemed too soft at speed on the highway.
The Monroes GT sports were designed to compliment Kings lowered springs so maybe with softer springs they are just too soft.
Anyway very happy with the Koni's.
I also have some KYB AGX adjustables to fit on the front that I got a while back but haven't had the time to fit and was going to get some matching KYB rears but these Koni's came up at a way better price than I could get the others at.
I had no idea this thread existed!!
What a sensational car, Very Very nice mate.
Great to see an awesome car being spoilt..lol...
Oztrack dyno tune 289.4rwkw bolt ons only.
Just had Steve from Oztrack do a dyno touch mafless up tune to my VZ LS2 @ Race Solutions, Penrith, Sydney.
I'm very happy with the final figure of 289.4rwkw with bonnet closed and filter in place.
We got a few more ponies with the filter out but as I don't drive it without the filter I'll stick with the 289.
Also have to give credit to Steve for his "mail order mafless tune" as the car pulled 284rwkw on its first dyno run before Steve started playing with the fine tune.
The engine is all bolt ons with Dus OTR, 1.8 YT roller rockers, 25% under/drive balancer, Sureflow 1 3/4" HPC shorty extractors with 3" ballistic cats backed up by the std HSV catback and an Elite oil catch can to keep those nasty octane lowering oil fumes out of the intake.
Plus it is running std AC platinum plugs about 30k/klm old.
impressive result for a ls2 with boltons and an auto.
what exactly does the 25% under/drive balancer do for you?
The 25% underdrive balancer drives your "accessories" (alternator, water pump and power steer) at 25% reduced speed which in theory means the engine isn't using as much energy especially at higher revs to drive them.
Because LS engines rev so well in comparison to earlier holden V8's the reduced accessory speed isn't usually a problem.
I haven't heard of anyone having problems with the reduced speed.
quick question did the headers make the car any louder??
im looking to make mine abit louder but not over the top loud.
thinking going a xforce twin 2.5 stainless catback or just changing the headers since the hsv system is twin 2.5 aswell.
only bad thing of the stock system is the big quiet resinator
The extractors didn't really make much difference to the exhaust noise but the ballistic cats did and another plus for the cats is that the lite drone that is still evident even in HSV system is completely gone.
The VZ is a straight through system but in the rear resonator the pipes twist from vertical to horizontal but you can still push a garden hose easily through it.
The way HSV quietens the system is to continually keep making the system slightly smaller as it heads from front to back.
BTW between the stock exhaust manifolds and cats the the pipe reducers to 2 1/4" before exiting the cat at 3" into the 3" secondaries.
Between the 3" secondaries and the centre mufflers is 2 1/2", between the centre mufflers and the rear muffler is 2 1/4" and finally out the rear at 2 1/16".
The supposed 2 1/2" HSV tips are only 2 1/2" outside diameter.
you have just made me want to sell my calais and get a senator with th cream leather i just love it,.
Thanks I love the interior.
I was originall looking for the grey interior because with playing with cars all the time.
I thought the cream leather might get a bit grubby but it looks much better than the grey and so far been able to keep it clean.
I bought this after owning a L67 wagon for 12 years and I have never regretted it, I still love every drive in it.
