01 cobra only running 14.15?? (video)

four.six · Jul 28, 2005

shouldn't a STOCK cobra run ATLEAST 13.9 or 13.8??.... i ran 14.1s, 14.2s all night long. take a look at the video and tell me what u think.. maybe my car is not running right?? or do i just need to work on my launches?? i think i could have a slight exhaust leak, could that make me run slower?? this is the video from my thread the other day "01 cobra vs. 94 Trans Am"....

Work on your launches

Between your reaction and your 60' you should be able to knock off almost .5 on streets and a solid .5+ on DR's

there is the timeslip!!!

Pittsas · Jul 28, 2005

yeah I just grabbed it off your other post cause it's needed info

WillDuhhBeast · Jul 28, 2005

Did you fall asleep at the light? UGH

stangman · Jul 28, 2005

reaction time DOES NOT affect e.t.'s

& yes the launch could be part of it, but it's hot as balls all across the south, so i'm sure that played a part in it also

WillDuhhBeast · Jul 28, 2005

Yes, I understand that the E.T's aren't effected by the reaction time, but damn.. .96?

Beau · Jul 28, 2005

your density altitude was what? that could have an effect on it, as could your inability to pull a good 60 foot time.

i'd rather cut a 10.1 reaction time but have a good clean run cause i 'took my time' at the light

DBMSTNG · Jul 28, 2005

what RPM are you shifting at? it may not be optimal to shift the 01 Cobra at redline.

Without knowing what the density alt. is, it's impossible to say if that's fast or not. Seems about right to me with that 60ft.

Did you mention what kind of tires you were using? DR's, streets, ....?

WillDuhhBeast · Jul 28, 2005

I almost cut a 2.2 60ft on a stock 03 GT in Florida.

I suck at the track too!

I'd imagine we both need alittle work on the 60ft. I'm on stock tires too, so that doesn't help. I met a guy down there with nitto 555's on, it was an older Maxima. He was tearing me apart with minor mods, but got very good traction. I was impressed... he sold the concept of "rubber matters"

that was my first run of the day...

i shifted right before the red.. like 6800 or 6900, fuel cut off is 7000...

street tires. cant afford DRs yet.

how do i find out the density alt??

you should be 2.0-2.04 for 60 ft.
reaction time has nothing to do with ET.
1/8 mile should be 8.8-8.9
the 1/8 mile per hour is low... very low. 80-81 mph at least 79.
1/4 mph is ok.
it looks like your first 1/8 mile killed you. you need to drop.2 off 60 ft.
practice
practice
practice.
now you see how hard it is to get a good ET. you need to experiment with rpm's at the line. some cars like some tirespin then a solid grab for good 60ft. some like clutch slip to reduce torque on tire. MY best advice is to bypass all these techniques and purchase nitto DR's or whatever brand you like. the rear end will suffer.(spider gears). MPH trap speed at 1/4 was probably good because there is less shifting and more legs in 4 valve. 13.9 is a good time. What is your altitude? you need a correction factor.

but i must say, first ever time at a real track thay is an excellent result. there is no telling how much time you will take off with practice.

billfisher · Jul 28, 2005

also

also experiment with shift rpm's. a lot of new guys shift too late thinking it help ET. try runs with incremented RPM shift point to find if you have a torque car or HP car.
