i'll keep this short and simple. Last thursday at the local car meet a guy with a brand new scat pack challenger wanted to have a little fun several us went out and did some runs.

sadly i did not have a passnger to video but here is how my race with the scat pack went.


From about 50mph me in 3rd and the challenger in 2nd he honks it off and on the hit i jump out about a full car length. i hit 4th and hold the car length on him and bye the top of 4th he was dead even with me .

we went back to the meet and he was a bit disapointed that a 4 door yellow cobalt held off his brand new 50k dollar challenger. lol

 

whats done to your car ?

 

K&N drop in filter with airbox mod, Hahn catback, Tune 23psi

 

nice trifecta or HPT ? any idea of your whp/trq ?

wish you had a video lol

 

HPT

it made 318whp 362ftlbs on a dynojet

yeah me to! lol

 

Is this a 370HP 5.7 or 470 hp 6.4L challenger?

 

holy **** 6.4L 485HP gets WORKED by a yellow cobalt ahha

 

Car runs 12.9 quarter stock. Totally believable from a roll.

4200lbs is a bitch.

 

12.9 is slower than expected I thought SRT8's had a low 12 in them.

 

I dunno. not like they went from a 20mph roll....where he has that MUCH traction issues.

I would say the challenger woulda reeled him in...

motor trend: QUARTER MILE 12.6 sec @ 112.3 mph

a lot of them claming 12.2-12.4 times as well.

 

Challenger makes 35% more power. Weighs 40% more. Should be an even race.

 

really? I don't think 160hp gets lost cus you weight 1200 more pounds. just my 2 cents

 

9.2lbs per hp in the cobalt vs 10.07lbs per hp in the scat pack (pulled up a challenger forum noted 417-420whp) and the curb weight is from C&D at 4200lbs, so the cobalt pulls until gearing takes over

 

A lot of people don't understand that's when you both have traction, most of the race involves power to weight ratio. The challenger is a fat pig.

A lot of people get butthurt by small cars because they don't know power/weight very well.

 

being fat helps traction tho...especialy on a higher roll.

I guess my expierence is different. my ls1 Camaro weight 3100 pounds and put down only 401hp cam only and ran 11.2xx

so my expierence is 1000lb less

 

On a 50mph roll the cobalt has most to full traction. So traction is almost a non issue.

Yeah the new Camaro is 3400-3600 lbs. At 455HP it should walk a Scat Pack.

 

A roll is not the same as at the drag strip. I'm sure your LS1 Camaro had a 60' time of around 1.5 to pull a 11.2

 

That weight is a killer sometimes

 

going off of motor trends 1/4 mile trap speed of 112mph for the scat pack i'd say the race was about right due to knowing that my car trapped 111 spinning all of 2nd.

his gearing was taking over also after about 130 he started to inch away.

 

i wouldn't say "worked" as the balt only pulled a car at the beginning and then got reeled in slowly by the top of 4th gear. impressive none the less.

 

yup. ranged from 1.53-1.56

 

Look at the challenger trap speeds... barely over 110. That's slow as **** for the power.

I ran a new 6.4L one when they first came out, it couldn't even beat his cousin's new 5.0 mustang, my Z annihilated it on bottle. They supposedly only trapped about 108-110 back then, they've gotten slightly quicker, but aren't fast. My Z on motor alone was trapping 104, with 270whp and weighing about 3400lbs.

 

Im not sure thats true, I think I have full traction from a dig.

 

your cobalt is rwd lol ?

 

uh...its about the FRONT...not rears on balts?

x2

you can have a 335 back there ,wouldn't matter.
