I have a small quick question... I see people going through the 1/4 mile in 14.0 - 14.3 and trapping at 97-98 mph, so my question is why is it that i trap at 101-102mph and only get a 14.6?? thanks guys

 

what's your 60 ft?

 

around 2.50 - 2.60

 

Traction, and a better 60' will get you in the 13's. Those mph's are showing you that your car has the power to net you faster ET's but you aren't getting out the hole fast enough

 

Are you serious?? 13's??? I'm still stock...I thought best was around 14.1 - 14.2 stock?

And a bit off topic, i never rev before taking off, do you think it would help me get off the line quicker? thanks again

 

Those MPH's should be good for at least a high 13 I would think. You could get off the line a bit faster if you tach her up a bit before launching, just don't drop the hammer ya know?

 

hmmm, I know, just scared because i had a god damn clutch go with only 25K clicks on the car and i would rather not repeat that experience!!

 

You are trapping 102 mph stock?!! That is one crazy beast you got going for yourself and it's stock!

 

Maybe he bought it with Stg2 and doesn't know about it

 

yup, 100-102 mph everytime....what should it normally be at? and no there is no stage 2 on it, redline is around 6500rpm and boost only goes to 86-87 kpa (12.5-13 psi)

 

what track is that?

napierville has lots of problem with stupid speed readings these days

look at this: Eclipse GT with CAI

runs:

15.278 @ 122.038
15.048 @ 96.296
15.003 @ 123.003
15.198 @ 97.493
14.888 @ 99.735
14.636 @ 121.774
14.793 @ 98.262

a 20mph variation in trap speeds and 120mph with a 15.2 E.T.? I think not!

yeah, I always go to napierville but evertime i go i usually trap around that!! and my cobalt ls does the quarter in 16.3 - 16.6 and traps at 85 - 87 mph.
here are the time slips last time i went:

Cobalt SS/SC
run 1 : 1/4 = 15.083 @ 101.98(lots of wheel hop that time) 60 feet = 2.657
run 2 : 1/4 = 14.623 @ 101.757 60 feet = 2.404

Cobalt LS
run 1 : 1/4 = 16.364 @ 87.557 60 feet = 2.646
run 2 : 1/4 = 16.511 @ 86.099 60 feet = 2.701

Anyways, just saying that it is always consistent

 

as your 60ft goes down. you mph will go down as well.

 

but why?? i'm just not getting how this works!! if my 60ft go down and my mph go down will i be slower in the 1/4? i'm confused

 

Check it out man, I traped at 108 before and ran a 13.7 then later I trapped at 107 and ran a 13.6. I got off the line much quicker though, remember its not about how fast you pass the line. Its how fast you get to that line. Its measured by how much time it take you to cover a distance.

 

No because you will be getting off the line faster....the quicker you reach the end, the lower your time will be...think of the 60 ft as almost like a 0-60 time...u want to get that number as low as possible

I don't know why either, but when you do hook, you tend to trap lower..not by much but it will be noticeable

 

Yea, I mean think about it. Take two toy cars and race them down a line. One in your left and, one in your right hand. The car in the right lane could be spinning the tires and not getting off the line as fast as the car in the left lane. So it appears the car in the left lane is faster. Finally half way down the track the car gains traction and begins to pull very hard on the car on the left. To bad he runs out of track to catch him but traps higher. This is because the car in the right lane was going faster when he passed the 1.4th mile line. But the car in the left still had a better E/T with a lower mph because he passed the line first. That should make sense to you.

 

if you trap 103 mph with a 2.2 60ft.
next pass you trap 101mph with a 1.9

what happened.

you spun less, you got traction. guess i shouldn't have worded it like that the first time. it's simple. keeping the exact same power you have now. your mph will drop because you are spinning. you stop spinning, or rip off a 1.5 60ft. you're mph will drop like a rock. along with your et.

i trapped 103 in my car on the DD tune.

i had a gsx that trapped 103. and went 12.74. the ss/sc went 13.70

1.60 60ft in the gsx, vs 2.0 in the ss/sc.

 

just a bit off topic....I noticed someone gave me neg rep for name calling in this thread!! Did i miss something? did i say something wrong? jeez
