i did 14.6 @ 96mph with a 2.1 on 60 foot with street tire.
no way you can get 14.3,not with just 2.1 ( i mean with your setup)
no additive.

Taylora, if you want an idea for how fast your car will go with whatever mods you do, compare it to a 97-02 GTP. The 96-99 SSEi'* are only a tad bit slower than the last gen GTP.

Hmm, the ones I run against at the track all run 14.9-15.1 stock, just like the SSEi'*. The 96-99 SSEi'* are only ~200lb heavier than the GTP'*. :?

If you have an SSEi, your car will be about one second slower. The Bonneville’* are only a few hundred pounds heavier, but they are slower for several other reasons too:
additional weight (several hundred pounds)
poor weight distribution for drag racing (things like the battery in the back seat, aluminum hood, aluminum control arms and aluminum front bumper all work to reduce the percentage of weight on the front tires, resulting in less traction during acceleration)
larger front brakes (more rotating mass reduces power put to the ground)
larger tires and wheels (increased rotating mass takes more power to accelerate)
restrictive PCM (much more aggressive traction control system cannot be overridden by simply pulling a fuse; PCM will actually retard ignition timing if you try to power-brake the car)
no Performance Shift function (so shift points are lower and shifts are slower)
no air opening behind the headlight means that removing the headlight won’t give you any cold air

and with better traction his speed will decrease.
i raced a '04 GP comp G with 3.4 pulley, rocker 1.9 , headers downpipe(stock pcm) he ended with 14.3 @99.5 mph with a 2.3 lauch. thats a 13.8 13,9 with a 2.1 launch.
i was in front of him till end of 1st gear. with 14.692@96.2mph 2.192 launch.
i agree he can get 14.3, but not with a 2.1 launch.

My high 60' aren't from spinning tires though. I have to be conservative from the start while rolling on the throttle becaues of the poor track prep, and even then, the tires break loose from a 20mph roll on the track surface. That'* why I have a low trap speed as well as a high 60' for the times I run. With the track prep they usually have at the track, if I was any harder on the throttle I'd spin through most of first gear and end up running something like 14.7 @ 95, which I did on a run with a mid 2.3sec 60'.
Sorry if this thread is going off topic.

I did a 14.7@94 with a 2.24 60', stock no track prep. If I get my 60' down to 2.1, I would be in the 14.3 range
