Well i have noticed there is always little 6 vs 8 threads around the place so i figured lets start a heavily modded one that will not get out of control.

For me, i much prefer an 8, they sound better, they are much easier to get going faster, they don't use any more fuel when driven nicely around town and best of all chicks dig them

I have asked on here time and time again for people to show me examples of 6's in where there are 11 second NA ones getting around, no one is yet to provide with me this and people usually dance around the fact and go on to say how their car can beat LS1/LS2 variant cars no problem. Well thats all good and fine but before you do a comparison on how great your V6 is, do a true comparison.
To compare a any FI vehicle with a stock NA application is just stupid, it really is if i were to charge my Senator, i doubt any 6 would come close to me with a simple bolt on and tune.
Fact is, the 6 is highly limited and very expensive to really get going fast especially in our heavy Australian cars.
I know alot of guys here mod their 6's which is great it really is, but please do not keep comparing your FI applications to stock of the floor V8's it isn't even a comparison, instead, take it to the track and compare it with an 8 of similar mods, race it at the track and see how you go.

And last but not least torque....nothing puts you back in your seat quite like a V8.

PS: I could get more technical, but i won't, i think my post is pretty much sums up my thoughts.

[Guru Spook]

For me it's sound, and grunt. Something a V6 doesn't have.

Yes it's quite possible to make a 6 (Even a 4) destroy a V8, but being the fastest isn't everything.

Usually it's a unfair comparison anyway. As if a stock V8 will beat a modified Turbo.

They soon back down though, when you strap a Turbo or Supercharger to the 8.

[AttaBoy]

Well I own a V6 because I just do. Its good enough for me now until I get a better car.

I'm only 21 so no need to hurry to get a v8. But I can tell you that my 6 is faster than most 4 bangers out there lol.

I prefer a V8 over the 6 any day but for now V6 will do.

In a year time (Late 2008) I probably can afford a low mileage VY SS. or hopefully VZ.

I think thats why most people modify 6's is affordability, although, i wouldn't imagine parts would be much less for the 6 over the 8, it would be the initial car buying price.

[Grennan]

Well owning a 6 personally, i was going to supercharge and had great big plans. Ive thrown them out the window and im saving for a VS Clubsport, or even a VT series 2 5.7L.

My reason? I weighed up the price and gains of a modified 6 vs a stock/modified 8. By the time you get exhuast headers, rockers, cam etc etc youve racked up a couple of grand and your still getting nowhere untill you strap a blower to the side of it. With a v8, i can chuck a good exhaust and extractors setup onto it and be pushing 200kw (assuming this was done to the VS Clubby im saving for)

Compare the gains of the v6 with a exhuast and extractor package, cam, CAI, some head work etc etc with the gains of those same mods on a v8 and its absolutely mind boggling as to why i even thought about doing up a 6.

Sure the v8 costs a couple of grand extra, but you wouldve only spent it on a blower that got you just past a stock 8.

Well it comes down to the old saying "nothing compares to cubic inches" of course the v8 will have it over the v6 in any application its like comparing apples an oranges. When you start modifying them the same way the v8 will still come out on top but i dont think people mod the v6 to have real biig horsepower car its more the fact that you can mod them to be very quick and beat alot of v8's an still have better than v8 fuel econamy and rego.
Our car is a good example it may be s/c but it is factory stock 180kw and can beat a 185/195kw v8 of the same year and still get 550-600 kilometers to a tank of fuel in city driving. supercharged or not those same v8 have more power and torque then the s/c v6, with the same money spent on mods the v8 will probably out do the s/c v6 in topend but the look on the face of those v8 drivers when you pull away off the line and they are left playing catchup is priceless.
Pricing for parts for the v8 and v6 are pretty much the same although some are dearer than the other for each the overall cost for the same level package would work out pretty close but power levels would be very different.

[spxdsn]

I gotta agree, i'd much prefer an 8..

Minux, not so much cost in terms of modifications, but for a male under 25 there is a significant difference in insurance costs and police attention they draw.

Valid points, i still don't want to compare an Fi with a NA application, regardless of whether it is stock from the factory or not.

Rego, people pay less for a 6 than an 8? That would suck, in Vic it doesn't matter what your engine capacity is.

Very good point, one in which i had forgotten, insurance would be a super killer for a modded 8 under 25.

[180sc]

yeah in qld our rego is done by cylinders them more you have the dearer the rego.

[vt1538]

One comparison I would like to see is the Litres/100k of these 12 sec boosted sixes versus the 12 sec V8's. I doubt that there would be too much difference economy wise. If anything I believe the V8 would be better.

[dijm8]

i own a 6 but only because i have a casual job n its very cheap to run... $20 bucks a week will last bout 8 days :P only because work is down the road haha, but as soon as a get a full time job here comes the v8 and i cannot wait for that day :P

[vh-holden]

insurance is cheaper for a 6. in the nt, rego is based on engine capacity.

i'd love a v8, but can't afford to buy one that is in the same condition as my 6, and then to pay the extra insurance.

then again, i prefer the old 202 to the v6.

[pow3rslave]

i own a v6 because my car had everything else i wanted in it when i found it, and it was the only manual commo i'd seen in my quest. i've got it putting out some decent power after mods, so i'm happy. less insurance means more money for mods in the future if o choose.

if i was looking for my next car and a v8 fell in my lap the way my present one did, with everything i'm looking for, i'd get it. but wasn't willing to sacrifice manual for power. more power, but less fun imho.

[hingo1983]

I drive a 6 and its got plenty of power for my daily driver. It is a dream to drive to and from work everyday and gets great economy on the longer drives. My old man drives a VY V6 which tows a caravan. Its also got plenty of power and he says you can hardly tell its towing anything at all. Not to mention better fuel economy for your everyday around town driving.

Thats why I'm keeping my 6 and I'm going to buy a V8 Monaro next year for my weekend car.

My old VT had 340 rwkw, had quite alot of work done to it, i wont go into exact specs, ran a best time of 11.2 with slight back off. Around town with normal driving i'd get 400 km's on the highway around 650. This was an NA application so it was a little thirstier than an FI setup.

However, with spirited driving the town setup would last maybe 200 km's.

I will just add that when it comes to building a fast car i think the last thing on your mind is fuel economy.

I would be more interested in how an 11 second 8 drives compared to an 11 second 6.

Why not have your cake & eat it too?
As for the drivability of an 11 sec 8 to a 6 this would definately be a good comparison. There are plenty of 11 sec V8's with great street manners. I havent heard from any 11 sec V6 cars so it would be hard for me to compare.

mmm cake

I havent heard of many 6 second V6 commodores, not daily drivers anyway, can any 6 owners have more input???

[Sweetas_VT_SS]

Ok here's my 2cents...

If I was going for sound an 8 IMO will always sound better, and if I was racing at willowbank every week I would also choose an 8 as well, but as I do 95% of my driving in and around town, I find my modded super 6 to be ideal. Rego is cheaper, insurance is cheaper and depending on my mood fuel consumption is better than the 8. Also as 180sc said, nothing is more priceless than the face of V8 drivers when the lights go green and they're already playing catchup. Having driven all three (modded super6, modded V8 and stock Gen3) for daily driving and the occasional squirt from lights to lights the Super6 is much more fun in my opinion.

People like watching V8 drivers faces when they are in front of them, dangerous habit to get into when you are going forward

If you can, i'd suggest trying to get a passenger ride ina blown/turboed LS1 setup, the fun compared to your super6 is like comparing the ferris wheel to sky diving

Each to their own though. I am still amazed at how rego goes up depending on cylinders, kinda silly if you ask me.

[Grennan]

To bloody right. My mate works at a servo, and im usually there with him on sunday ****ing around in the backroom playing guitar hero with him. The amount of people he gets complaining about petrol, rocking up in 6L VE's and is rediculous.

Theres just something that screams testosterone when you get in the seat of a rumbling V8. Its something a V6, blown or not can offer.

Usually its just a quick glance in the side mirror, they're usually too far behind quite quickly so I only get a spilt second to check....

I agree, a turbo/blown Ls1 would be a dam site quicker, also lots more expensive (rego, insurance and whatever the FI cost). Plus unless you frequently head to the track or spend a lot of time on the freeway it would be a shame to have all that power and never really get to open it up.

Dont get me wrong I am a big V8 fan, just IMO its more economical to most.

If I"m already playing catch up when the lights go green it means you have jumped the light.

Or it could be like me where you stall it up at the lights then take off like a grandpa, i do this quite often, amazing how many people at the next set of lights tell you how slow your car is....

[stocky]

meh. mines a bit of fun. hasnt cost that much for the power its making, and when im done with it, i can probably sell it for the same price ive spent. ill get onto working a v8 eventually

Are you sure they didnt turn left at the lights?

It isnt that much more expensive, apart from the difference in the cars price. A blower from CAPA or the likes, cost about the same for v6 and v8. You get more power for about the same money from a v8. And well..rego thats just plain silly. Atleast Victoria has got something right and charges us the same regardless.
