just got back from the track very happy with my times

heres my best slip

reaction .355
I1 2.283
I3 9.34
ET 14.3
mph 98.8

i have an 03 cl-s auto my mods are icebox and obx headers and a set of es 100 tires
i ran a couple of weeks ago without the headers and i got a 14.89@96.xxmph

i didnt think the time would go down that much with the headers, but im sure with a better 60ft i can get a 14.2- 14.1.
what do you guys think

 

nice. what was the temp and conditions?

 

Wind Chill/ Humidex : 11°C
Barometric pressure : 100.7 kPa
Relative humidity : 66%
Wind : 7 km/h W
Dewpoint : 2°C

this is the approx in F°
54 degrees f

 

Is 2mph & 5 tenths a normal gain for headers alone? That seems like alot. What were the temps and post the entire slips for both passes.

Posting the same topic in two forums

 

I went from a 14.5 to a 14.2 and from 96 to 98. My short time is better than his though. I hit 2.1s on both Intake only and I/H runs.

 

best run with the icebox alone is
slip:

60 ft 2.29
I3 9.66
et 14.89
mph 96.6

best time with the icebox and headers

60 ft 2.28
I3 9.34
Et 14.3
mph 98.8

 

good run !

 

nice run...I suck!

 

dam a 2.1 60 ft is good
no matter how hard i try i get a 2.28 -2.30, with a 2.1 i should be at like 14.2 to 14.15
is the tire width make a difference cause my dimentions are 215/50/17, mabye i should have gotten 225/45/17

 

225/45-17 would help. they're wider plus a little shorter.

 

My personal best is 2.0

 

what kind of tires do you have and what are your mods for your 14.1 run

 

See signature:


FYI: My best run was at 80* F. Hopefully i'll get some faster times this weekend.

 

Nice run man.

Drop that 60' down and you'll be sitting pretty.

With I/H and a good driver an Auto CLS can be a quick car.
