I mean that is a difference of 5mph which is a lot. Also, i do have premium gas, 91 octane which is the highest that is offered here in AZ. Also, i do have the vdc, but that is only for launches, so i can spin the tires. Doesnt really affect it when you are doing it from a roll. I launch about 4500 rpm, i get a good tire spin but he pulls in 2nd. Car is just slow period and i am bothered by it because it should be faster.

if you want a drag car, do like me - build an FFR shelby cobra with a

I think there is something seriously wrong with me G. I think it is just dirt slow. I raced my brother that has a 2003 350z auto and he spanks me...BAD. He ran a 15.0-15.2 @ 94-95 mph and he is spanking me by atleast two cars.
I have an '05 coupe and I've had it to the drag strip on two occassions. My car is bone stock and my best time in the 1/4 is 14.3 at 101 MPH, and I've never been slower than 14.5 at 100 MPH. It seems from your post that your car is at least a sec slower than mine. If I were you, I'd take my car to the nearest speed shop to have it checked out.

And you are driving stick so it can be partly on your part too, either way turn vdc off because when your changing gears even off roll you need to chirp (make tires peel a little when changing gears isntead of having traction lock you in) and just keep going i mean your car might have a problem, but i think you should fully see if its on your part or the car? does the Z have anything in its engine?
I agree with the VDC off but I don't get your logic.

i think ur not launching at the right rpms.. i have an 04 and i launch at 2.5krpm or 3krpm.. also if ur going pass the redline as others say ur not doing anything but reving ur engine... try taking ur car to an open area and learn wha rpm its good for u to launch without burning rubber in one spot and wa rpm to shift into 2nd and 3rd... on mine its about 6.2k rpm slap it into 2nd. anything pass that its jus a waste.. thats prob why ur getting spanked.....

First, when you say the z only traps around 95, what are the conditions? Is it high altitude? The assumption that your car will trap 99 to 100 is based on good conditions.
Second, ignore all these people telling you to shift earlier. You've got the revup motor, which holds peak power all the way to redline. There is no reason to shift earlier. And Klubbheads is right about the indicated rpm; the tach on your car reads high. So shifting at an indicated 7200 is closer to 7k, give or take, and depending on gear.
Klubbheads is right again about vdc. Vdc shouldn't be on any time you race. Period. If it's wet outside, you shouldn't be racing anyway.
And you're launching too high. There is no reason to launch at 4500 on street tires. You'll just spin. Not to mention that will kill the clutch. Launch at a more conservative 2500 to 3k.
Lastly, a CAI will do nothing for the revup. The revup hates CAI's. If you're dead set on an intake, go with the JWT.
