Don't see how a timing chain is gonna effect the torque curve of a car. Must have been radical changes to plenum to get the cars running that good.

Why? When he stated if he was to get a Ford it would be an auto XR6.

And it's they're NOT there.

sorry my english skill are not the best mate

The timing chain redesign fixed that horrbile wheezy whiny noise you get from the VZs, the intake helped it breath better at high revs to smooth it out more. The different tune and exhaust design saw the increases your speaking of.

All I will say is you don't buy either car if you're that worried about 'power'.

I've had my VZ for over 2 years, put over 60,000 km's on it.. Worst mishap was a flat battery after work one night.

Fuel economy sits around 11, drops to 9 when I go to the coast & back.

Never misses a beat, can't fault it.

Ahhh yes I know that whining noise all too well, makes it sound like an electric car revving up. Its easily overcome by the stereo volume control when Im driving haha

Personally, im a toyota/nissan fan... but if i was to go ford or holden i would chose the Ford XR6 over the VZ... its a much smoother car to drive and a lot nicer both inside and out IMO...

Depends how you like to drive, if you enjoy revving cars hard for performance its the alloytech and if you prefer more effortless performance get the barra...

barra is lightyears ahead of the alloytecs

dont know if its the alloytecs i drove or theyre just simply not a good engine but to me they seemed sluggish, and sounded like ass?

Won't be looking to make great power out of it..but just simple exhaust/tune mods to make me happy.

Just trying to find out info on both cars...Keep it coming thumbsup.gif

Please don't put an exhaust on a 6. Unless it's boosted, it will sound like crap.

"Enjoy" is the wrong word for what you are describing. Yes, it performs better up in the revs, but there is nothing enjoyable about the sound it makes. Anything over 4 grand and its excessively harsh and noisy in the cabin.

the SV6 has the paddle shift too which is awsome. I dont know if Ford offer that or not do dont know what its like in that.

At the end of the day, there is no comparison between the two, the commodore if far ahead in looks, comfort and handling ect.

About 70% (rough guess) of Road tests/reviews show that the falcon is better in Comfort, handling, NVH and interior styling. (Unless the artical is written by that goose Paul Gover)

Good point, i agree the new alloytech are more economic, buck lack power even more so to make up for it, and the difference is a bees dickk.

But if we are tlaking new motors then its the Barra 192 he wants, not the 182.

Next year the Barra will be a compltely new design as well.

There isnt too much avalable to modify the falcon either

But simple in the way that all you need is a BF XR6T exhaust, Thypoon lower air intake, XR6T Upper intake, K&N Filter and your good for 200rwhp all up about $400 worth of mods, match that with a 6 speed (as everyone else suggests the 4spd is SHIT) your looking at a great package, and the selective shift is awesome and funn for an "auto" car.

Then you can also look at getting 20% underdrives, LSD and Throttle Body spacer and your looking around 210rwhp

I,m making 250hp at the tyres now Mick on Hi-Torque's dyno wavey.gif

I own an SS Commodore but if I Was to buy a 6 it would definately be the Falcon. We have the Alloytechs at work and they are crap cars. Do yourself a favour and get the Ford.

vz sv6 looks heaps better and a better interior but a ba/f falcon especially with the zf 6speed will drive better and will generally feel newer for longer, holden tend to start to rattle and feel used alot quicker, imo if your looking for a nice looking car get the holden and if your looking to to travel and see high milage get the falcon

Straight six engines are inherently better than V6 engines because of their design. Same as straight 8's are better than V8's. The problem is they are a bit harder to fit under the bonnet..

Straight 6 over a v6 anyday. The commo motor is poop. Weak and brittle, the ford motor is much better.

Please elaborate on this statement. In reality BMW etc chose an inline 6 is due to refinement and balance. However, V configuration engines can produce more torque and are more compact.
Neither really means one is better than the other.

And what car since the 30's have used an inline 8 cylinder?

answer your question?

im sure its a fair assumption that manufacturers would have used straight 8 engines if they weren't entirely impractical.

No it wasn't awesome. I drove a VZ calaias with paddle shift for a few months and I hated it. The up shifts were stupidly slow, the down shifts felt like you were letting the clutch out very slowly. The gearbox never responded well to the user input. It was no different than holding gears with the shift knob on any other automatic.

The ZF 6 speed however is almost perfect. It holds gears when hill climbing or cornering, it drops back gears when going downhill, it senses your driving style and adjusts shift times and responsiveness to match, its dead smooth and only has the torque converter on first gear.

That gearbox with the I6 leaves the alloythrash waaaaay behind. The only thing holden can offer over the falcon six is the V8 with a manual box.

and then the falcon comes along with the straight six turbo!!! ford ftw

Practicality does play a part in whether an engine is good or not don't you think?

Car makers do the best they can within the constraints they are placed under.

My experience with it, is the complete opposite to that to say the least. Also, i didnt know the Calais had them. I looked into buying a VZ Calais and i swear it didnt. unsure.gif

Although an inline six cylinder engine can also be timed for inherent primary and secondary balance, a straight-8 develops more power strokes per revolution and, as a result, will run more smoothly under load than an inline six. Also, due to the even number of power strokes per revolution, the straight-8 does not produce unpleasant odd-order harmonic vibration in the vehicle's driveline at low engine speeds.

yeah but how long would a straight 8 be especially with all the new tech and gizmo's added on lol.

more than double the length of a straight four. i.e. bloody huge.

I am sorry. Is this coming from the man with the 300ZX. No offence, but I was under the hood of my very good friends 300ZXTT the other day and if that is your version of "practicality", "compactness" and "doing the best within the constraints", well. I like his car but you must love pain to own one...
