First time at the track last night.. ran a best out of 3 runs...a 15.194. Thought I would break into the 14s.. even a 14.8 or 14.9
you guys have any tips for next time.. how to improve reaction time..? etc.? my best r/t was 1.247 which is pretty shitty isnt it?

could it because i was running with 18s on and a spare in the trunk..(half tank of gax) and im not the skinniest guy either.. im 218-220lbs?..

I wanna run a 14.6 stock(CAI) like that other dood here (shawn S) i think..

Shawn S has a 6spd. Mattg is running some impressive times...but he's not too close to stock...14.2 if your interested. Take out the spare. How's the tempature? If it's hot, your CAI will hurt you more than it will help you. What about tire? What kind of tires are you running? Are you launching without burning out? Sport shift, gateshift, flooring it...which one? How heavy are your 18inchs? What was tire psi?

bullaculla

your R/T has nothing to do with your E/T. When the light turns green, you can just sit there for 5 seconds and then go, and you will still run a 15.1
Don't worry about your R/T just go when your ready

I am RobG

what are your 60ft times?

darrinb

i dont think a cai even helps you in the 1/4, maybe like .05 of a second. but any ways post your 60 ft times so we see if you had lots of wheel spin or other problems

Here is my time. I realized later that I could have don't much better, due to my tyre pressure. Tyres were hot and at 42psi. And I had traction problems, so next time I will lower em to below 35....hot.

I gutted the car as much as possible without having to bust my ass putting everything back in.

I gutted the trunk "NOTHING" was in there. I had less than 1 gal. in the tank. I took out my passanger seat. Tried to take out the back seats but couldn't find the bolts that were holding them in.
I weigh 185lbs. , and my mechanic says that I could shave a full second off my times if I stoped eating like a pig . And all I could do was break 15s.

bullaculla

Damn Rob! Thats an impressive time in your sig, even more so with all that extra weight! I need headers

peiqinglong

Don't forget to turn off your traction control.

jucee187

my best 60' time was 2.430
TIRE PSI was untouched.. standard i guess..(40PSI??)
temperature was pretty cool...night time..
I gate shifted..D1 d2 d3
green light .. floored it..
no burn out.. how can i do a burn out with auto?.. just stomp on the parking brake and gas?..
turned off VSA..

my 18s feel lighter than the stocks.. when i pick them up..
im running with Kumho rubbers.
whats the deal?..

FDao

It's your 60Ft time. If you can just get it down to 2.3's, you'll be in the 14.9's. Lower your tire pressure to 30 psi. Don't gun it at start, but rather roll into the pedal, then pedal to the metal thereafter. If your 18's are 20 lbs or lighter, than your acceleration will improve. If it greater than that, then your time will be hurt.

jucee187

30 psi on a 40 profile tire? is that wise?. ..
what if you brake torque?.. slam on the brakes.. and rev it up 2K then let go??.. .. and im trying to lose weight.. maybe down to 200lbs.. haha.
i wanna hit 14s .. damn it..

JRock

Plus you have all this working against you:

Larger rims and weight in the trunk.

jucee187

my box is not that heavy....and my amp is small .. maybe 3lbs.... and i took it out...for the run.. i guess its my rims.. larger diameter.. but doesnt the extra width make up for it?.. more contact area to the ground..
and i should of drained more gas.. i had the needle at half way point.. i shoulda ran with a quarter or less...
how about spark plugS?. mattg had IRIDIUMS on his 14.6 run.. do they make any difference?..

peiqinglong

The rims might be lighter, but because they are bigger...more rotational mass, so you get hurt there. Every extra piece of weight will hold you down, try removing the box and amp in the rear. Yes you can "burnout" more or less. If you straight floor it...you'll lost traction starting out and hurt you time. Well if you got good tires...it won't be as bad. Tire pressure part, I don't know if going 30psi as FDAO suggested is good or bad, but I noticed when you do stuff like this, you have to release some air and running a little "flatter", i believe that is to get maximum grip. You probably won't want to do that when you are normally driving, but maybe if your at the track though.

Guys.

Put my header in last week and took the car to Carlsbad on Sunday. It's sea-level and weather was awesome.

Best run was 14.1 @ 98. 60' was 2.06. Tire pressure up front
was set at 15psi and 40psi in the back.

I was so convinced before going that I could hit 13's... but unfortunately not. I think 13.7's are realizable with some M/T's or Hoosier drag radials.

Not going to go again untill I have the S/C and a set of slicks. I have some 14"x10" slicks with the 4x100 lug-pattern from my civic but obviously the darn things won't fit the CL.

On street tires, I doubt the S/C will put the car in the 12's. I think 13.3 @ 108 possibly.

Maybe if it miraculously lost 300 lbs!

jucee187

nice collections of cars u got there allmotor..

FDao

If you're running only at the track and have access to a air pump thereafter, it's no problem. Bullacula achieved 14.77 in his 6-spd with front tire pressure lower than 30 psi on 18's. Brake torqueing, IMO doesn't improve the 1/4 mile too much as I noticed we get too much wheel spin, although some members here swears by it.

bullaculla

26psi, and my car is all stock

jucee187

14.7 6spd is not as good as mattG s 14.6 auto time.. maybe hes a skinny ass dood.. although he did lower his pressure.. he was on 18s too.. 23 lbs each... i think i figured it out now ..sort of....
lower front tire pressure.. take out spare.. loose weight.. and 1/4 tank of gas.. or less.. cool temp..and dont mash the pedal right off the start..
hope this works....
thanks guys..

Really even a 1/4 tank is too much have the fuel needle either at the red line or below. When I ran I had the neddle in the center of the red line and was able to make 4 decent runs before I felt like I needed more fuel.

yea my 14.6 run was with the needle on E and the gas light was on

this was on my previous CLS only mod was an intake.

Scrib

Weight is definitely an important thing...

But the difference between 1/4 and almost NO gas has got to be a non-issue, don't you think?

I mean, 1/4 of a tank is roughly 4 gallons, correct? I believe the tank is 17.2 gallons... Anyhoo... Let's assume 1/4 a tank is four gallons. At 6.1 pounds/gallon (what gasoline wieghs), that's 24.4 pounds at 1/4 tank...

Compare that with maybe 1 gallon or just a bit less when the needle is at 'E'.... ~4-6 pounds...


The difference... Roughly 20 pounds...

And I doubt you'd EVER be able to tell the difference in reducing 20 pounds of weight off this car.

Zapata

scrib,
It's liquid weight which shifts at launch. I'm sure it hinders acceleration......

Scrib

I see you point zapata, but I really doubt it makes THAT much of a difference. I'd have to pull out some old fluid mechanics books and see what's up....

Case in point... I went to the track, didn't alter my tire PSI, didn't GUT shit out of the trunk and had over a quarter tank of gas and ran a 14.8. And it was wet as shit out... IN fact they closed the track a couple of times due to rain and moisture.

I don't doubt that running with as little gas in the tank as possible helps, but I don't think a tiny bit compared to having around 1/4 of a tank would make much or a noticiable difference...

bullaculla

yeah, but it was only my second time drag racing, and this is my first stick! Also I had half a tank of gas! Plus I bounced off the rev limiter right at the end!!! If it wasn't so crowded I would have run again and posted a better time.
but next week i think i can do better, I'm much more relaxed at the line now

Juker008

Holly crap. With all that weight. Shit I took out my passenger seat, tried to take out the back seats but couldn't find the bolts. Ran the tank practly dry and throught that it would be a good idea to take out all my CDs from the CD changer. I mean 6 CDs is alot . But anyway the weather was poor it rained a hour before the track opened up. The best time that I ran was a 14.972 and that was at 82oF. So with all u guys pullin way better times I would have to think that I'm losing power somewhere. U think mabey its the tranny? I'm at 38K now and had my tranny replaced at 18K.

It could be the 82 degree weather. Anytime it's hot outside...like more than 70 degrees, the car runs like shit. When i'm in San Jose like during these times, my car runs like crap, but when I got to San Francisco and the weather is like 50-60, GAWD DAMN! The car is taking off so quick not even funny. Try it in better weather and you should be able to drop some of that time down. IT's the CAI that's hurting you.

bullaculla

it is always over 80 degrees here!!!

Oh damn...hrmmm...I'm sorry to hear that!
