Do not do a burn out with street tires, do not lower the air pressure with street tires, STAY OUT OF THE WATER with street tires, slip the clutch on launch, launch at 1500 rpms, powershift. Do all of those and you will drop your times.

Hey guys, havent been aound fo a while, but heres the update. I took a lot of time working on launches, and also got a set of nitto DR's. needless to say it worked out. My time went from a best of 14.9 to 13.8, same car and mods.thank you everyone for all your help though.

The most noticeable thing everyone overlooked was shifting RPM. If the motor is stock then shift it early like 5200 rpm. Try to shift every gear the same RPM and watch your timeslip for comparison sake. IF you keep your 60'fts the same and shift at say 5300 and the car goes faster then try shifting one pass at 5400 or 5200 and see if the times change.

Just because the tach redlines at 6k doesn't mean it still makes power up there. Most of the time shifting late like that puts you past peak torque when you drop to the next gear thus losing your forward momentum untill HP comes back on. When you shift earlier where the stock motor, heads, cams, exhaust, start to fall off it puts you back on top of the climbing or peak torque. This helps keep the car pulling it's own weight downtrack untill HP can really start to pull again.

Another thing you can do is shallow stage the car. There are 2 sets of small bulbs on the top of the tree. Pre Stage is the first set and Full Stage is the second set. Once all of them are lit the starter will drop the tree. If you light up the first set and barely bump forward until the second set is lit you'll have about 11 inches of rolling start. (Your ET clock starts AFTER you break the last Beam in staging) This is like getting a rolling start BEFORE the clock starts. You'll be able to gain a bit from practicing this too.

Now this will slow your reaction times unless you practice (important if you compete or bracket race) but it WON'T effect your times. Reaction Times are just that. Your time to react and break the beams once the light turns green.

IF you set there and have a 2 sec reaction time you can still roll out of the beams and run the same time. You're reaction time will have changed but your Elapsed Time will stay the same. I can't believe how many people mistake reaction time for better ET's. They don't have any effect on your ET at all. They simple mean you are reacting to the lights quicker or slower than the next guy. On a .5 sec tree you should shoot for reaction times of .510's or better. On a LED tree that is .000 for perfect you should shoot for .010's or better. On a pro tree that is .400 shoot for anything in the 4's.


Try keeping your launches the same and shifting a bit earlier and you'll pick up some time!

Don't forget to practice as well. You can't really get enough seat time!
