    hahaha yeah unfortunately he sold the SS and got a VX Berlina Gen3. I dont think he wants to mod anything power wise. Hes quite happy with it since we had a bit of a run and it munched my Senator :( .

    have you ever watched the GTP race series?
    they have mostly production cars like wrxs, evos etc and a few clubsports and gts's.
    its great watching the little toy cars get the jump off the line, then the big bangers reel them in on the straight as if they were standing still.

    to the original post, the only way a turbo 4 will get an 8 off the line is if the 8 has no traction. small capacity turbos have nothing down low, where the 8 is in its torque band.

    GLD-086, apples to oranges mate.
    like minux said, fit a 5 speed to both and the 8 will win.
    no replacement for displacement.

    The more air you can fit into the engine to more power you will make, the 4 cylinder engine is just half a V8 so you can't say one engine is better than the other since they are the same thing, the V8 has a few design advantages though as far as being more compact that two 4 cylinder engines and sharing a manifold etc. Also the more cylinders you have the smaller and lighter you can make the pistons and then you can make everything spin at smore revs without breaking and the more revs you can spin with more power strokes per/time you can make = more power, take note of forumula one, 18,000 revs buys you alot of power in a tiny little V8.

    Thats also why as far as out and out performace goes even though they are more efficient no four cycle engine can match a two stroke or rotary engine of the same size and revs, because they are firing more often. With a turbo even with a small amount of PSI (boost) you can easily fill the engine with 150% of the total air capacity of the engine so you will make more power but that said the 4 cylinder and 6 cylinder engines are inferior to the engines with more cylinders, it's just that they have alot less parts and are cheaper to make so will allways be more common and as they don't make alot of power with a turbo you will see them turbo charged more often. But in your top of the line models and high end sports cars, complex V12's and the like are common.

    And back to the original question of why a turbo 4 or 6 can pound a V8 on take off, most V8's from the factory are designed to be a slow long lived engine that can do alot of hard work without breaking. They send them out with mild tunes, mild camshafts, restrictive exhausts and usually in very heavy cars

    Yes I have and I think from memory the EVOs, WRXs were going very well and the 8s couldnt really catch up.

    Dont get me wrong, I would rather have a HSV than a WRX for alot of reasons.

    Yeah mate, true.

    I dont really care what would win though, I like both the 5 Speeds and V8s, so yeah, I dont really care what wins.

    Be prepared to spend alot of money turbo/charging it though promax =P

    A mate of mine keeps going on and on and on about how good the evo 9 is supposed to be. 'Easiest car to drive' and blah blah quick around corners. I'd rather have a quick 8 than a quick lancer.. even if they are better on turns. Straight line they'd lose =/

    yea i know i know.. i told everyone i'm going to twin supercharge my car no matter what price the petrol is, but i figured if i turbo n super charge it, it'll have a good high end power and good power off the line.... thats just my theory, i'm probably wrong but ah well

    but yea, i dont care how good anyone elses car is.. as longas i have a holden i'm happy

    only 900nm? only 450kw at the wheels? Single GenT 1000's are putting that out in a standard setup, torque is usually at about 1200

    Yea I agree with Minux. Those figures are pretty weak for what it is anyway. Twin turbos would be a great way to go.

    Why are you a moron? If lusting after performance makes you a moron, then a lot of people on this forum are..

    I'd love to see more FI 8's.. A twin turbo LS1 (even better LS2) would be a f*ckn beast.. I'd love to have one of them..

    The twin turboes arent that special atm, the Gent 1000 however is a different story...

    It is such a weird sound a turbo v8, very different, but awesome all the same

    Why does it need to be twin or both?

    I am hoping to turbo my SS, i just need to decide if i want NA performance, or PSI performance.
