Ha i love how on this forum that people look at amount of posts to diss people. Im sure there are pleanty of people on here with 88 posts that have been on the site for years and know ten times more than people with 5000 posts that do nothing but post all day.

Ive been on here consistantly since 05. I was actually going to be the FIRST AND ONLY fully built LSJ running the GM stage 3 kit with its full potential.
8k redline, 2.99 pulley, 50 shot, dual pass opt b, and high octane mode. It would have been sick. I had the high speed valve springs, neutral balance shafts, stage 3 PCM, 2nd reservoir, and pulley all set to rock and roll.
Then my cobalt started to take a ****. Once this happened I sold my **** and said F-it. So much potential, such a waste on all the bullshit that started falling apart. Im also friends with one of the fastest LSJ builds on this site, in addition to some LNF owners. I havent worked on the LNF as much as the LSJ, but I know my way around that engine bay.
So newbie, please take ur 88 post butt buddys hand and kindly **** off.
drag coefficient
gearing
track conditions
whp curve
wtq curve
max tq
max hp
engine efficiency vs temp
yada yada yada.
Sooo, where would you like to start?
power/weight is ricer math if youre not considering these other factors that I listed. As I said, you want to see the most accurate way ( and its not even that accurate at all ) an engine performs from a roll pay close attention to the trap speeds.

Hey 1BADSS/SC you have a video of your car performing at the track or at least against another car so we can see that monster in action against something other than itself??

all very good points, i'll give you more specific info, its was 10 degress celcius which should be around 40-50 farenheit. so no heat soak issues...
srt-8 gear ratios
1st 3.59
2nd 2.19
3rd 1.41
4th 1.00
5th 0.83
drag coefficient of .40
makes peak poower at 6200 rpm redline is at 6400 rpm
weight 5000 lbs vs 2900 lbs

we need mph with those gear ratios.
drag coefficient is on the cobalts side, not much but a little.
we need dyno sheets to see where the power band is for both whp and wtq
the cobalt may or may not have a better power/weight ratio based on dyno comparisons. Let me see if I can get some dynos posted to take a good look.
heres a dyno for an SRT8:
http://i77.photobucket.com/albums/j6...mondello-1.jpg
the curb weight is 4,788 lbs. and the gear mph are as follows:
I cant find them?
well, the power is as follows:
it looks like on the dyno sheet the SRT8 makes max tq of 386 ft/lbs at about 4600 rpms, and max hp of 371 at around 5400 rpms. After this point the power starts to drop off, but not much. With the wtq being at such a high rpm, this is an indication that the thing has monster top end considering the whp/wtq almost pull all the way to redline.
now lets move on to the cobalt. Here is a dyno on a stock LSJ. Its kind of a freak considering they mostly run around 215 stock, but I will use it anyway:
http://img510.imageshack.us/img510/5129/dustin3kk.jpg
The curbweight is around 2900, and the gear mph are as follows:
1st: 0-30
2nd: 30-60
3rd: 60-100
4th: 100-redline
^( I think thats how I remember the redline being on the cobalt )
OK, so lets look at the dyno. It looks like the cobalt makes max wtq of 192 at around 5000 rpm, and pulls max whp of 226 all the way to redline. So lets do some number crunching.
SRT8 vs LSJ
12.38 vs 15.10 lb/wtq comparison
12.73 vs 12.83 lb/whp comparison
now if you were to compare solely on max whp/wtq numbers, then the SRT8 has a significant advantage in wtq ( which will help it pull more in the top end ), and the cobalt has a minor advantage in whp.
The cobalt will be able to regain ground because of its higher redline of 6500, and slight whp advantage. However without knowing what the gears are on the SRT8 makes it hard to say whether it will pull in the top or not.
based on the massive wtq advantage, it would definitely pull the cobalt pretty good. In the top end, its hard to say. Honestly, Im not even sure what gear that SRT8 pulled those numbers in, or the cobalt for that matter.

Ok since I own a Jeep SRT8, I will chime in :-P. My friend, who is also a member on this forum, filled with car enthusiasts and the like, have raced from a roll. He, being the owner of an arrival blue ss/sc with mods: GM Stage 2, 2.9 pulley, 42 injectors, Vibrant catback, Injen intake, Tune by me :-),
And I, being the owner of a lovely Jeep SRT8, with mods at the time: none. We wanted to know the outcome from a roll. 40mph was the speed chosen. 3 Beeps and WE'RE OFF! My friend got a SLIGHT jump on me since I was deciding whether or not to use the autostick or not (i ended up using it last second hence my slightly slow reaction time). That slight jump made him jump in front of me about 1/6 to 1/8 of a car length and it just stayed there to ~100 mph where we let off. No one was pulling. I would imagine after 100 though he'd start to pull. EDIT: HOWEVER, compared to my cobalt, this truck has a higher top speed. My ss/sc with catback hit 146 and died. The SRT8's are known to do 155 stock. They still pull pretty good up top.
That is my experience with that. Tis all i'm going to add into this thread because it seems as if there's a little arguing going on and I do not want to be apart of it. Just wanted to share my experience with you guys. Thanks
EDIT: Just thought i'd throw this in for giggles... http://www.youtube.com/watch?v=_DW8FXOwF5E

he was even with the jeep until they shut down at 100 where the stage 2 was starting to pull.
i said the jeep pulled us hard up to 100 mph, and by 110 we were starting to pull back. our cars are cleary not as fast as the 2.9 pulley ss/sc as it was even up to 100...
top end the aerodynamics and weight of the jeep slow it down considerably. like i said we'll have to do another race just to be sure he didnt let off and do partial throttle. either way eh was still accelerating past 120 mph.
