Half of you guys can't be serious.
Trying to find power results, and calculate 1/4 times. You're looking at +/- 2-3 secs.
You could make a 250rwkw car do low 11's, with the right way about it.
Power isn't all that in Drag Racing.
What you want to focus on is Suspension set-up and splurge on tyres.
You could have a 500rwkw car with positive displacement coilovers wheelspinning the whole track.
Generally 90/10 ratio front/rear is a good start.
Stock suspension in the rear, get some coilovers at the front with 8-10kg springs, wind the dampening up all the way.
Tyres, can't go past Mickey Thompson's.
You got an R33?
Buy some R32 GTR wheels or even 300zx wheels. Slap on fat M/T's with good side wall flex 265/40 R16.
Get a good clutch too, Brass button, or even twin plate. Rear wheel drive cars need riding on the take-off to prevent wheel spin.
Lift Handbrake up and (hold the button in obviously so it goes down again) hold revs just before full boost. Let the clutch out until you feel it starting to bite...hold hold hold..and let go.
Get ready to basically slam second straight away.
Don't hit limiter.
Take out everything (YES EVERYTHING)..spare wheel, jack, seats incl passenger.
PRACTICE MAKES PERFECT.
Don't expect to get there straight away.
It's the battle that makes it fun!
ENJOY..
Hope that helps!
