  1. I understand what people mean when they say "detuned" but its just a common misuse of the word. It should never really be used appart from on the track where they litterally detune the engine when they have some sort of fault. Any other use is a miss use of that word, which I was trying to point out (although, I did a poor job). This is a bit of hearsay, but isn't the alloytech weaker than our i6? I wouldn't think it would be as strong as our block, from pretty much all angles (bock construciton, layout, materials used etc). This is just in my mind from a physics point of view, I don't see it being capable of handling the torsional forces like our 4 litre 6. Also... If was holden, every time I saw the figure "550nm" I'd crap myself.... Think about that, having 90% of 550nm avail' from only 1500rpm, peaking between 3 - 4 and holding above 90% till 5500. I don't care if they make a 300kw TT alloytech, it has no hope of keeping up with the above (its a peaky engine with no real low down torque, both wheels and motor agree with this). 475nm at 275kw sounds more like a 3 litre, or a NA gen3, rather than a turbocharged 3.6. Sounds like a blower to me, otherwise it would produce more twist (if 0.4 of a litre makes 75nm more with fewer kw, you be the judge).
  2. Valid points there mate, but even so, there is extra engineering involved with doing that over a normal inline configuration turbo setup. But I have heard that eventually there is always doing to be more wear on the 1 bank and can lead to course vibrations later on in the life of the engine (I haven't investigated this myself so I can't reference or prove this to you). What I do know is you can never fully balance the back pressure properly, without some sort of valving system, with 1 bank turbo'd. I've heard that it causes more problems than its worth. But yeah, with a V its much cheaper and easier to just supercharge. This is the most viable option and from a business point of view, and would be the one I'd take if I was in there situation. I have heard that this new v6 does take quite well to supercharging over turbocharging anyway, as it likes to rev more than the old one. Time will tell boys, time will tell. I just want Ford to give us something special, I just have this feeling that something is in the works, dunno why.....
  3. I still don't see it being viable cost wise. You have to sell the car with more than double the egineering costs. What does a motor cost these days, couple of grand? double that, add 20% for the engineering and research. Add this cost back into the car, stick another 5% on this cars total value and that's your selling price. This is about a 42k car with stock suspension and an executive interior.... To get the specs up, yor looking at about 55k just to start off with a sports model and a turbo v6. Sure, sell them to someone else, they can cover the cost as makes no difference to holden, but for Expensive Daewoo to use the engine it would cost too much in my opinion, and if they do it, they are very brave (problem is, their bravery put them ahead in the market, so lets hope it doesn't pay off this time if they decide to go ahead with it )
  4. From what I have read I am yet to see one. Not to mention his post was "I heard" not "I know". I'm not saying he doesn't contribute, but from the few posts I read they seemed to display a pattern of miss information and bad assumptions (much like I assumed the shifter was alloy, though, initial planning was to have it as alloy, but this was changed at the last minute according to ford. My assumption was based on a fact that was changed, so you can't really blame me ). My appologies if he was simply having 'an off week'. And the plastic used for the shifter could still hold your weight according to ford, so it must have been a defective part, not a week link. Cheers.
  5. I got my info from waaaaaaayyyyyyy back when they were just releasing the car, something to do with having an alloy stem. Well well, looks like that went out the window at the speed of light now doesnt it. And yes, it SHOULD BE if it isn't. Its a gear level, you would assume it was wouldnt you.
  6. From what I've read and seen it appears to be alloy. We'll have to check up on it now wont we

    Dyno

    0.7457 you mean
  8. What were they doing with it then? A gym session? As I've never heard of this nor seen any evidence of it. Hearing something doesn't mean it happened. I'm not saying its impossible, its just highly unlikely and would have to be caused by say, a crack in the core, as from the manufacturer, of that particular peice of alloy.
  9. Inertia IS NOT your friend.
  10. Cheers fellas I'm at uni and I'm relativly bored (doing mechanical engineering if you wanted to know, just waiting for a maths lecture....) So I thought I would come and give your nice forums here a thrash :D
  11. Is it just me, or does anyone else feel dumber after reading that? Plonky, I highly recommend you either stop posting or at least get your facts right before doing so. I've never heard of the shifter being broken. Considering it has a cast alloy rod going up the middle it, that is directly connected to shift mechanism on top of the box, makes this highly unlikely. I would suggest you could hang your weight off it, plus some of your friends, before it would break. Also, the only reason it wont shift down a gear is because you were probably trying to shift into 1st at over 65km/h. It won't shift because if you were decelerating this would unbalance the car significantly, applying that much braking force to the rears only, not to mention this also protects the gearbox from unneccissary wear. Also, say you suddenly wanted to go faster during this time, you would have only 1000rpm before having to shift again. By the time it shifts, the torque converter takes up the slack and you get moving, you would have already been going faster had you stayed in second. So plonky, please, stop.
  12. Please take some basic English lessons, AussieMan. As for a turbo alloytech, I highly doubt it. It only requires the most basic of engineering understanding to realise the cost involved in producing a turbo v* engine. If its single turbo, you have inherant lag issues with longer piping. If its twin turbo, you pretty much double your costs and hassles. It simply isn't worth it, and I'd like anyone who says something like "Expensive Daewoo will bring out a turbo 6 for sure" to just sit down and think about who is going to pay for an extra 40 kw, when that 40kw costs you allot more than a v8 with more grunt. And a detuned 300kw, hahaha, whatever. Please learn a bit about engines before making rediculous claims like this. It isn't detuned, as soon as you stick a turbo on it, it has been modified and therefor it is tuned engine. If that's the case, then you could say the xr6t is "detuned to 240kw". I would also say, in fact I would be sure of this, that the barra would get a greater increase in power for every psi of boost than the alloytech, this is obvious not only for having a larger capacity, but from a dynamics point of view, the barra has it hands down. Also, in the same driving conditions, fuel consumption for the SV6 is only 0.3L/100km better than the xr6NA (Check motor). Considering the 100kg weight difference, you guess which engine is more efficient. Sure, the new alloytech engine might need a little bit of time to wear in, but from what I've read, nothing changes in this department. Id like them to stick a passenger in the sv6 to make up the weight difference and then test what the fuel consumption is like.....
