i only raced six times never got the launch i was looking for but i put down a 9.44 with a .33 reaction time......does that seem about right for my car....knn drop in cat back and spacer????

 

every track is different... unfortunatley it's like asking if dyno numbers are about right... compared to what?

 

I hate the 1/8th but i did manage to put down a 8.5 with my 240 with couple of bolt ons and no lsd/ street tires...

 

all we have here is the 1/8th and i cant seem to get back to 8.8 again.. best this season is 9.0 in the g

 

that ain't too bad.

 

what u got done to ur 240sx.. i got a 92 240sx too still ka though

^ nice find those #'s look close to what you would run (in my case). I'm #1609.

I remember running a 9.2 1/8th when I was N/A and my 1/4 was 14.1.

 

ive always heard just taje your 1/8th mile time and multiply by 1.55... its close to the same as urs u posted

 

i like urs better because it puts me in the 13.4 range for the 1/4 mile

 

Thats not bad with your mods. Getting off the line is going to make a HUGE difference in your ET. Keep in mind that the reaction time has no effect on your ET. For example, whether you had a .00 or a 1.9 sec reaction time you still would have run a 9.44: Time doesnt start ticking until you leave the line.
