Well....when ur racing an automatic car....is it better to just floor it and let the engine do the shifting or when say u get around 4000 rpms.....should u release the pedal so it changes the gears real quick?
Question about racing an automatic car.

If it is unmodded that sound you will be hearing is your tranny gernading itself if you just drop it in at 4k.
let it do the shifting. if you release at 4k, then push the pedal down again it will just downshift
When "Racing" mom's Camry, just floor it and let it do its thing. It knows what it's doing, and it's doing the best it can.
the best way would be to replace it with a manual gearbox 
but really, if you want the best start possible, hold down your brake, rev up your engine, and release the brake. and if you car has a good amount of power (i.e. you get lots of wheel spin if you floor it), give it just enough gas so that you get traction then floor it.

any auto when shfiting is very poor..but then it depends on the software and number of gears.
If you got an option to "shift between drive and lower gears" I will run it as a stick it would be faster than letting it shift by holding it down like my mom's dodge neon does.

No doubt that manuals are fun, but don't forget the number of pro's using autos so don't be so quick to say a manual is the better way.
If you're asking if you should be lifting your foot from the pedal as you go down the track to try to make the car shift earlier, the answer is no.
I have an auto integra and can shift between 1, 2, 3, 4, N like any automatic. What I do is put it in neutral, rev to about 3000, then quickly put it into 1st gear and floor it. I'll get some wheel spin, then hit it up to 7k RPM and switch to 2nd (since there is a delay in switching, i push the shifter to 2nd at about 6500, then keep the gas floored till 7000, then release the gas when it shifts, then floor it again....)
On my familys 2001 Pontiac Montana, if I keep the pedal to the metal it gets up to the redline before I release it...it doesnt seem to automatically shift (maybe it will but I dont want to risk going any higher)
First we need to know:
What kind of car is it?
What kind of transmission?
What is the rear-end?(dear god please don't say fwd....)
What is the motor?
What are the mods?(please exclude "fiberglass oil cap" etc)
Approx HP/Trq output of the motor?
Then a good answer can be given.

Not good for it at all.
IMHO, built auto tranny's are just as good as manuals. Unless you're a skilled driver you get more consistency with an auto at least.
You're going to break it and loose speed. Never drop from neutral to drive with the engine reved up. You can do a brake stand by holding the brakes and bringing the engine speed up to the desired point then releasing the brake and mashing the pedal. I'd recommend against doing it for long as it really heats up the fluid. And of course I'd recommend against doing it often as well.
Everytime you lift the gas pedal you're closing the throttle blade and dropping speed. Keep the pedal to the floor until you're done accelerating even if you choose to row the gears on your own.
Don't do that. As mentioned, that is known as a neutral drop, and it's very, very bad for the transmission.
The "brake-torquing" technique is acceptable, but generates a lot of heat in the fluid, so don?t hold the brake for very long.
Don't.
Unless it's against another automatic owner. A manual geared minivan could practically 0wn j00. - M4H
Of course I know it's bad for the transmission. That's why I haven't done it for 2 years and only did it once or twice before that. But, it IS slightly faster.
In any case, I have timed it to be faster to shift the gears yourself than to put it in drive and let the transmission figure it out. About 1 second faster in 0-60 by my timing.

In identical cars both with stock transmissions, manuals are faster. However not all manuals are faster than autos. Take a peek at what kind of trannies bracket racers use and you'll see what I mean. Plus, for most people(because they can't drive for shiaat), its a lot better for them to 'race' an automatic. Its way to easy to shift yourself out of a race if you dont' know what you're doing and have a manual. With an auto the car will help you be less of a f\_/ck up.

neutral drop=bad!
A good tranny kit will allow you to tailor the shift points to where you want them. I use a stage 2 kit from Trans-Go. This way I can leave it in drive and still bang off great shifts. Mine shifts at 5200 RPM and grabs rubber going into second while using P245 60 15 tires. I use an A998 Mopar trans (pro-built) with my modded 318.
If you want better, than get a reverse manual valve-body kit done to it. This way it is like having a manual with no clutch.
Who says auto trannies suck compared to manuals? A blanket statement means nothing. In Mopar muscle car years, the autos were equal or better than the manuals for 2 reasons. 1. autos would cushion the power so traction while using small tires wasn't hampered much. 2. We had great automatics to start with.

why are autos slower then manuals (expect the start that you can't rev it)? Can't they be "programmed" to have the perfect shift-timing? Better then any human can ever do?
Wow another mopar man! Good call with your tranny insight. You ever visit moparts.com? That's my car hang out board.

They are slow because they use a torque converter instead of clutch. That's why some cars are now using a combination or the two; clutch to minimize power loss and somewhat automatic shifting(you still have to tell it to do it
