what is it that makes our cars soo slow
^ Simplest answer.
^ Mostly this.
SP ran 1.4s in their 6 speed car. They have the quickest 6spd Z 60 foot time that I know of. I wasn't referring to Zs but to supras and SC300s, 300ZXs, etc, which have run well into the 1.3s. They are pretty comparable in terms of launching.
Once guys get around to perfecting drivetrain setups (i.e. axles that don't break, clutches that work like they want them to) and more and more guys start geting into those power levels, 60' times will start plummeting in those high HP cars. Fact is that most of the guys with high HP Zs don't drag race them much, and as such haven't come close to tapping their cars' potential, the vast majority of high power 350Zs these days are dyno queens or cars that just cruise around. They don't do any real motorsport or if they do they don't take it seriously enough to really excel at it.
They still won't be as quick as the 'glide n' transbrake cars because there's a lot more that goes into 140, 150, 160mph runs than just the launch, but the gap will narrow significantly as drivers start getting more seat time and learn what parts and techniques work.

Why do some Z owners act like god when their POS cars break down every other week?
but back to the point, so if you go from 1.7s 60' to a 1.4s 60', that will give you a second in your ET?
Nealoc, can you point me to a Z/G pulling 1.3-1.4sec 60 foot times?
Of course no one is comparing a t-brake car to a manual, but how much more difference does that make than launch control (2 step along with antilag) on a manual?

A few comments:
First, as others have said... I have no problem admitting my personal street car is a terrible example of power vs drag 1/4mile et. My car is NOT a drag car, and was only taken to the track for fun on that one appearance where it ran a 9 second pass. It is a full street car without a cage, which is why I have not been back to try and get the time down as the power would allow. A 9.8 is no where near a full "clean" pass or the potential of the car, but I doubt we will ever see that under my ownership as I don't care to take the car back. I have other cars for that
Second, auto vs manual. This has already been discussed... but an auto with a lined out launch is going to drop times and make them more consistent. Our green drag car was running consistent low 1.4s I believe, and even ventured in 1.3s with very minimal suspension work and adjustment. It should be in the 1.2s, but we had not invested the time into setting up the suspension. Any time savings in the 60' will more than apply to the 1/4 mile time.
Finally, I can't believe no one has mentioned suspension geometry. IRS vs solid rear... it takes significantly more work to get an IRS Z to leave the line like a solid axle foxbody mustang. Even if you could get the camber correct (which is not possible w/ the normal camber arms/toe bolts: 0 on launch, which means + when sitting there...), it still moves from ideal as the car squarts/unsquats. This is big.

Few Z's are concerned with drag racing, compared to other platforms that have been hard at it for years (see: domestics). There are also almost no 'worth-it' venues to drag race a high horsepower 350Z, so you don't have people out there all the time trying to go faster.
^ I hope all of this changes
Random Trivia: The 350Z has a longer wheelbase than a Supra, which is positive. 104.3" vs 100.4"

You still haven't answered the question, you just posted some nonsense ******** and evaded it. Answer this question noob:
If you're never below 4000rpm, why does it matter how much more torque a V8 has at 3000rpm than a V6 at 3000rpm?
You don't have a goddamned clue what you're talking about and should probably avoid spouting off nonsensical ******** in forums where people with hundreds of 1/4 passes are discussing racing. Just some (not so) friendly advice.

My 350Z when it had the stock motor with a bolt on APS kit.
A Corvette Z06 before and after some mods, look at the before dyno and it very closely mirrors my Z's dyno in almost every aspect.
Both are right around 350 ft/lbs @ 3000RPMs and the Z's torque peaks EARLIER than the 7.0L V8 LS7
V6 vs V8...
Your theory =

^^ ya my buddies stock Z06 had about the same trq/hp curve as my tweaked vortech setup. He sold teh car before we did any hwy runs... Chicken
I thought one of IP customers (name escapes me, but he just made a thread recently with a low 6s 1/8th) had a solid rear end.
I know he had a ladder bar suspension or something like that as well.....

^ Yes, Mike's Z has a solid rear ford 9" setup.
