Drag racing question..
 

I was wondering if on the launch of a 1/4 mile race, is it best to floor the pedal at launch or is it best if ya gradually give the car more gas??

I have a automatic accord coupe 07 4 cylinder vtech and its quite fast at launch.

hold the brake in and slowly reav it to a lil less than half your rpm limiter then onces green light goes full pedal and let off brake, unless your tires brake lose then use less gas, but have your engine reved up as soon as it goes green

or just follow heeroyuy's advice

holding the break on an automatic? Isnt that bad for the engine or something else??

The reason Im asking this question is cause my boss wants to race 1/4 mile.

He drives a 05 impreza and he thinks he can smoke my accord. So I wanna just smoke him from the start!![cursing]

its not bad on an automatic as long as its just to hold a lower rpm and your not WOT

I havent driven an impreza b4 so I dont know how fast they are. His is not a WRX nor an STI its just the low end impreza. It doesnt seem like its all that fast.

Anyone know?

if u got a v6 accord ull probaly win,

a reg imprezza is only like 160 hp he may get the jump but your should catch up and win

if u got a 4 cylander its anyones game

He said in first post it's a 4 cyl.

The 2.5i imprezas are pretty slow. If his is a manual, it's anybody's race. If he's got an automatic, you'll win unless you really screw up bad http://discussworldissues.com/forums...es/tongue1.gif

And yeah, keep the RPMs lowish on yours (say... 2-3k RPM) while holding the brake, then let off and brake and floor it. It's not great on your car, but it's not horrible either. Especially at stock, it shouldn't cause any problems. Just don't do it a lot

If it's a manual,he'll definately lose,my OB is heavier and only has a 2.2,but due to gearing they have they're quite lively when you mash on the gas,at least the manual's.

Manual 2.5i is good for about 8 second 0-60.
The Accord should be right at 8 seconds as well.

Impreza with the 4AT is closer to 10 seconds though, what a dog [rofl]

I love my 5spd and 4.11 final drive...and snow,I really love snow.http://discussworldissues.com/forums...ies/laugh1.gif

his is a manual impreza. Im thinking he might have me on the launch cause of the AWD

Another thing, I tried reving my accord and it limits itself at 2000 rpms, it wont go past that even if I floor it

It's possible he'll have you, but honestly... both of you have fairly low powered cars, traction is not exactly a big problem. Launching your car from 2000 RPM I would expect very minimal tire slippage so AWD isn't as big of as advantage as you might think.
In fact it might work against him (extra drivetrain drag) depending on how long the race is. Assuming it's legal and at a drag strip, I'd put my bets on your car in the 1/4 mile.

agree with what he said, adding another driveshaft and **** loses another 15-25 % hp total so i'd put money on u

get it to 2k light goes green you go all the way to the floor and dont let up

also turn overdrive off
a/c off
heater off
windows up
remove your side mirrors
put tape over your grille holes
take your antenna off
turn your radio off
turn your lights off
remove spare tire and tools
run on 1/4 tank of gas
put an extra few pounds of air in the tires
dont eat for a week
poop first

and you should have this

LMFAO I actually almost got a tear from that....gg[rofl][rofl]

The drag race would be on a side road next to our 1 sq mile facility...so theres plenty of road and minimal traffic...theres no light there so a 3rd person is gonna have to signal our go!!

Good ol' street racing days.. ahhh... I definitely don't miss that.

What's the closest track you guys can go to, if it's close go there, it's like 20 bucks to get in, run as much as you want. At the end of the day you have a number and if anyone wants to dispute it tell them to get one..

I've had a lot of these so called I can whoop your car etc etc. They'd challenge me on the street but wouldn't go to the track. It bugs the **** out of them.

On the street, one can start half a second, or a second before you, that helps a lot to either one.

At the track, your time is recorded when your wheels start moving so it's more fair that way anyway.

I just skimmed through this thread so I don't really know the specs of your cars but if his car is underpowered and 4wd.. heavyyyyy... so no advantage there.

Good luck and stay safe.

Theres no race track close by, the street next to the facility has more than enuff room for a 1/4 drag race. The only thing is we have to look out for trucks commin in n out which doesnt happen but every 10-20 minutes. Theres no traffic other than the trucks. and we can always radio our drivers to not get on that street when we race, so we'll be good

Don't know where you guys are getting this revving it up on the brake from - the torque converter will have a stall around 2k rpm, anyway.
One of the previous posts had good avice about turning everything off, etc. Make sure you've taken everything out of the boot (spare, jack, etc) and interior (misc' junk that accumulates).
Do a couple of practice starts and see what the characteristics of the car prefer - if traction is limited, you may be better using a little throttle against the brake, some vehicles need a little more and some will be best with little pre-loading. You may wish to increase rear tyre pressures and, perhaps lower the fronts if wheelspin is easily provoked - otherwise you may want to increase them as well.
Regardless what you do, DO NOT load the torque converter up for more than a few seconds as overheating of the transmission fluid can occur very quickly - all the power the engine is producing is going straight into the fluid.
Check the shift point of the transmission - some vehicles will hold on close to the redline, others may benefit from manually changing.
Something that gets frequently overlooked is slop in the throttle linkage - you can check for play and reduce it to a minimum. Check it's opening fully by having someone press the pedal to the floor (engine off, obviously) and checking the throttle is fully opened.
Use a higher octane fuel for a while - this may not give more power but if the fuel quality is compromised, the engine management may be compensating for it and reducing power.
New air filter if the old one looks like it needs changing.
DO NOT (!!!) rev the engine in neutral and drop it into gear - a great way to destroy transmissions!

Wear a crash helmet - street racing is stupid and potentially dangerous and it will give you a better chance if the worst happens.

My advice?

If you can't find a race track, forgot racing. Act like a man and let him dance around claiming his car is faster, it's not worth the risk.

So what if you win? You won't have a bigger penis.

Worst case scenario? You kill someone, someone's 6 year old daughter.

So do you really care about proving your car is faster.

_ThouGHtlesS_: Not ragging on you since I used to do the same but the track I go to is an hour and 15-20 mins away. I drive there, race, drive home. I wouldn't go unless I thought my car couldn't make it or if I didn't have a ride home.

That's about 30 bucks gas back and forth, 20 bucks to race and 4-5 hrs of fun. No risk in getting a ticket, endangering yours, your buddy's life or someone elses.

I guess I smartened up after I had a few close calls.. also there are people that will call cops on you if they find out what's going on. Be careful.

Edit: Also at the track, you get the proof of the number you have. I usually tell people.. get a faster number and I"ll pay for your gas and give you 100 bucks, if not, you give me 100 bucks and all you wasted is 30 bucks on gas. Hasn't failed me once because they all chicken out and by default that makes me faster ;)
