There's a 13.6 for you right there, even without perfecting your launch control!!

Anyone watch the Nismo 370z on Motorweek this week? They got it to do 1/4 mile in 13.8 sec. Said it was incredibly difficult to launch.

I'm pretty sure the reaction time doesn't affect the ET, Jorge.

Correct, unless you are racing someone.
Reaction time is worthless if you are just going against yourself, you can sit at the green and wait if you want, the clock starts when you roll forward.

Really!?!?! Damn, that means I really didn't run a 13.9 with my Eclipse turbo when the slip said 14.2 and my friend told me to back the r/t out!!!! That's what I get for listening to another amateur!!! Thanks for clearing this up Ray.

he could wait at the line for a week, still would have ran the same time.

I don't know why so many people think RT means anything when you're out at a test and tune. It has no impact on your ET at all.

I was at the track last year and this ricer Scion driver was telling me how he'd be running 9s (8th mile) if only he could have a second off his RT. I didn't rail on the kid but I politely pointed out that RT doesn't matter and you are stuck running 10.99s.

I had no idea so many people thought RT was factored into your ET!

Seems like this thread may need sticky! Reaction Time has no impact on Elapsed Time

Id cry, lol , jk ...

I would just feather the clutch from 2500 in such a way that you never spin and are always moving.. it wont get you the best launch but it will prob get you a 2.2 or better with your mods.

And did you go through the water pit and not do a burn out ? I would just go around the water. than do a small burn out just incase your a little wet and than line up...

Im going to the track on wednesday, just dynoed a very generous number but my expectations are tampered this time because im on stock rubber with limited tire left... I want a shot at it before I get a Drag Radial setup. Than im expecting to pull 1.9 60 foot or better. .7 better than your first pass within the first 60 feet ! lol think about that, its crazy how much time there is to be made up in the first 60 feet.

You should always avoid the water box if possible... a small spin isn't going to be enough to dry them off, and you don't want to heat the tires too much prior to your run.
