    Do you have a graph of the torque curve ?

    no...thats all they gave me...now you mention it I'll go back and ask for it. I actually thought that the dyno automatically did both readings on the same chart. Is there a reason why torque would be omitted?

    Maybe they didn't click that button on the pooter ?

    Most people seem to only want to know max power figures which, in real life, don't mean much coz how often does one drive at those revs ?

    Bottom end torque improvement is the key for the street coz that's where you generally live on the street.

    I just went down there and he basically said that being a stock cam that there is not much of a torque graph to look at.
    He printed it out for me anyway..

    Decent power for stock engine vx auto...must still be a healthy one lol.

    Can't remember if better manifold started on vy or vx,suppose to be small gain over vt version.

    If doing cam/lifters have a look into getting heads skimmed 20-30 thou as reckon that makes most of the gain on dyno when dudes get cnc heads.

    Downside is all little things start to add up like pushrods,trunion upgrade,lifters...

    Plenty of d.i.y things to keep you busy whilst saving like....throttle body water bypass,full throttle mod,de-dagging manifold,heat insulation under intake & if not done already catchcan.

    I've had a couple of quotes that have ranged from just over 5k to around 8k. 5k was for cam/converter. 8k was for a complete top end rebuild/converter.. Its quite a difference. The guy at 8k was probably the best in his customer service. Family business but explained everything including the heads being shaved and the rest of the usual, valve springs, lifters etc.
    I figured the quote at 5k would probably end up to 8k in the end anyway.
    The car is basically a 2 owner (3 including me). The last owner bought it off a funeral director in Bunbury after it was 12 months old and then he owned it till I bought it. Older guy too so I'm assuming it was well looked after or lightly driven. I bought it at 168k and in the past couple of years have had 9k put on it.

    I've just made a small update video (similar to the other video's in this post). It really is quite a different car from when I first got it

    Nice power , I've got 422 , but huge torque increase = supercharger = stock cat back, airbox , maf meter still fiscally in line.

    VERY Nice indeed, the Polish and Buff has brought it up, looks great,
    I did the same to my VY, as the paint had oxidise a bit,
    User a paint Cleaner, then a Polish, and then a Wet Look Wax, [all Meguiars Products] and its looked great,
    hang on to it, because it maybe a collectors item soon, after what was announced the other day,
    I was taking to a wreckers in Geelong not long ago [approx. 10 months ago], as I bought LSD off him for my VY, and he said to hang on to mine, and other owners of VTs > VZ's should hang on to them,
    as they will be worth bit more I a few years if they are clean units.
    [That was his exact words]
    PS: Always liked the VX SS, something about its shape and syle.

    Cam only seems to generally give approx 260-280rwkw. Add heads and that generally seems to add 20-30rwkw. But since a dyno’s just a tuning tool the numbers really mean nothing when compared to numbers from another dyno.

    You can have 2 identical dyno’s and they’ll still read differently. Tyre pressures, diff gears, converter and how tight it’s strapped down has a massive impact.

    Certainly coming along nicely there, mate!
    You can see a pretty massive difference in acceleration comparing the first video to your last one. Really shows how much even basic things like a decent exhaust, intake & tune really opens these cars up, not to mention the 3.9's.

    Bit of an update today. I didn't think I'd be doing the cam until later in the year but a sticking lifter sort of pushed the issue a bit.

    So I got the lifters, timing chain and gears, camshaft, springs, pushrods,high stall, oil pump etc done.
    The heads were machined and a few other small bits and pieces.
    I went for a crow cams 871251. 235/243 .5916/.6086 lift and went a 2800rpm stall.

    I have a few vids coming up when I make/get them. I'm hopefully getting the dyno pull and going to do the usual rip up my little street but I'm suspecting this time around I might have to wait till the neighbours are up the shops.
    I did a quick idle vid today after I just got her back and the dyno results are there too..

    not sure what the next step is now. I'd like to to tidy up behind the wheels with maybe a brembo kit and some nice rotors. Rebuild the transmission which would finish my driveline or get a closed door respray to tidy up some car park dings, thinning paint etc.
