i am doing some research on both the cobalt and srt-4 even more since i got killed again by a supposive stock srt-4 even with all my mods

can anyone please find the weight of the cobalt ss/sc and the weight of a srt-4

i would also like to know the torque of a srt-4

and if their brake boost actually helps a lot??

alll help is appreciated

 

alright well i think i found some of the answers

srt-4 torque 250

and srt-4 weight is 2880 lbs

correct me if im wrong

does anyone know the weight of the cobalt??

 

about 2950 or so

 

mine weighed in at 3010lbs with me (245lbs at the time) at the track 1/4 tank left and no weight reduction.

 

...that reminds me, i need to put my spare tire back in with that heavy ass cover.

 

SRT-4's weigh about 2800-2900 depending on equipment

They are pushing 230 HP AT THE WHEELS (270-280 at the crank)
They are pushing 250 Tq AT THE WHEELS

the extra 200 pounds of weight that the cobalt has isnt going to make that big of a difference . . . maybe about 2 tenths in the 1/4 - maybe

C&D (street launching both cars)
Cobalt SS/SC Street start, 5-60 mph: 6.2 sec
Cobalt SS/SC Zero to 100 mph: 14.4 sec
Zero to 60 mph: 5.9 sec

Srt-4 Street start, 5-60 mph: 5.7 sec
Srt-4 Zero to 100 mph: 13.4 sec
Zero to 60 mph: 5.3 sec

Whats your cobalt pushing at the wheel?
and what break boost are you speaking of ? - if your talking about the old school break boosting by holding your breaks down to build your RPM's up . . .that has zero effect on a manual transmission

Im not sure what mods you have - but a good driver can make an SRT haul ass (a good driver can also make a cobalt haul ass as well) - What mods do you have ?

 

SRT4 - 220-230 whp
SS S/C - 210-220 whp

Both cars weight in the 2800-2900lb range- Mined weight 2798lbs (car) + 110lbs (full tank of gas) + 240lbs (me) = 3148lbs. Takin into account scale error the quote of the cobalt being 2806lbs is probably the most accurate.

 

I didnt realize the SS/SC was pushing 210-220 at the wheels ? why does chevy rate it at 205 ?
C&D rates it at:
Power (SAE net): 205 bhp @ 5600 rpm
Torque (SAE net): 200 lb-ft @ 4400 rpm
Now granted C&D doesnt test the cars - they just pass along the numbers they were given . . . now 205 at the wheels for a cobalt i could believe . . .but i have a hard time believing chevy underrated that much

I didnt realize chevy undererrated that car ? Chevy normally doesnt . . . .
(im not knocking . . . im truly curious)

Again I dont see how much of a difference 2-300 pounds is going to make between the two cars . . . i think focusing on the weight difference is useless

 

My car with me in it came out to 3030 pounds. I weigh about 130. This was on a race car track scale.

 

130 ? damn your skinny! hah - i weigh 205 im 6'0

 

My car weighed in at 2894 lbs with me in it. I'm 125 lbs. Hehe...I guess you could say I did some weight reduction

 

Dang you guys are lightweights lol. That's why I wish my g/f would have driven my SS...there would have been a 13 stocker for sure.

 

actually they underrated it quite abit! i just got my first dyno on my STOCK ss/sc and i got 228HP & 197TQ. myabe i just got lucky though!

 

Im really suprised
-

Also - upon further investigation

SS/SC Curb weight: 2911 lb
Srt-4 Curb weight: 2984 lb

The big gulf between the two is torque . . .

srt will hit 130mph 5 seconds faster than the cobalt . . .where is the cobalt loosing all its speed ? - AGAIN im not knocking - im curious

Theres actually a used one at the ford dealership over here . . . i shoudl test drive it

 

I have a friend that owns an SRT 4 and it ran a 13.9 stock. The Cobalt SS will typicaly run about 14.3 to 14.5 stock. The driver makes a difference as does some DOT approved Drag Radials.

 

I understand that . . . im not that dumb heh

but Car and Driver tests the cars in there stock form . . . chances are the same driver tested the srt and the SS/SC -
in stock form - with stock tires - the SS/SC is slower than the SRT-4 - And if chevy is truly underrating . . . im as curious as the next guy as to where its loosing its speed/power

 

I have raced SRT's before. Ive lost and Ive won. The srt pulls alot harder in 3rd compared to the cobalt's 3rd, but the cobalt has the advantage in 2nd over the srt (Similar power levels of course.) That being said, I don't really know why, Maybe the cobalt's 3rd is to long? Does a stock srt cross the line in the 1/4 mile in 3rd or 4th? Why does the cobalt weigh more than the srt? All things I'd like to know.

 

not much of the man about srt's knowledge but when i dyno my cobalt stock it had 214hp and 199ft tq .... that i would say chevy underated them just a tad!!!!!!!!!!!!

 

torque=acceleration, hp=top speed...that is where the cobalt is losing power...not as much torque through the midrange like an srt.

 

Not as much torque through all the bands really . . .

As far as why it weighs more . . .alot of it is probably b/c its a tad longer than the SRT

As far as second gear goes . . . My second gear pulls like a bat out of hell . . .actually - I usally chrip my tires the whole way through 2nd (im stock) - Ive never driven an SS/SC before . . .

First gear in an SRT is **** b/c you get no traction at 100% throttle . . . to launch an SRT - you bascially need to feather it and never hit more than 75% throttle . . .

As far as third . . . i cant say . . .but i think 3rd in my SRT is ALOT more doggy than 2nd . . .

-------

I might just try to test drive an SS/SC this weekend - and ill try to give my honest un-biased opions of the two cars
- Im actually a pretty un-biased person for the most part -
We'll see

 

No clue why GM underated them, but i have heard that when GM tested the SS the S/C in the test car was heat soaked, but all hearsay.

As for the weight i agree I dont think a couple pounds make that much of a diff, but i have seen 2 cars race and they only won when the passenger was in the other car. As for the SS running out of steam later on in the speedo, I think its because the M62 is not that efficent, some lack of torque(compared to the srt4) and as well the gearing is messed up.

 

SRT guys are usually pretty cool.....but you can couch your comment in as much pretty wording as you want, your calling bullshit on the Cobalts stock WHP, which has been tested countless times.....and you yourself drive a similar domestic tuner car that is known for the exact same form of underrated horsepower.

You think the SRT can be pushing 270 at the crank 230 at the wheels but everyone elses car is exactly what the mags say?

damn dude. come down off your pedestal.

 

If you dislike the SRT-4’s 1st gear then you are going to absolutely despise an SS/SC’s. It is incredibly short…I’m assuming it is geared (no pun intended) more towards auto-crossing than anything else. In a stock SS/SC, or at least mine, the 1-2 shift would always bog the car down unless you “gently” shifted into 2nd or power shifted into it to keep the rpm’s a little higher in the powerband. It wasn’t until I got a slightly smaller pulley that the car wouldn’t bog down @ the beginning of 2nd gear.

Curb weight is subjective in my opinion. My Cobalt was lighter with me in it than all four of the SRT-4 members at the track that night with no weight reduction, roughly the same amount of gas, plus I was one of the heavier guys too.

 

The SS/SC first gear goes to about 27mph, thats hitting red line. I always laugh when I think to myself that I can barely break the speed limit in my neighborhood in first gear... lol.

 

LoL - I hear that ! - I think the SRT is like 30mph or something (Its been awhile since ive redlined be gears)

It irritates me when I wheel hop and spin like none other


I knew someone would somehow get offended at what i said . . .(thats not what I was aiming at)
And yeah I DID have a hard time believing it (GM isnt in the habbit of underrating) But then people put their numbers up - then i beleived it . . . Read post 14 - I never once tried to deny it after that point

If you would read - i said that i was suprised by the numbers ! . . . I NEVER claimed to be on a pedestal - Nor did i EVER claim to be an SS guru - I didnt know they were underrated! - thats why i was asking the damned question - If i was trying to be a jerk . . you would know it

As a matter of fact i was just telling my friend that i work with that GM did underrate the cobalt (he was asking me about them) - I think someone needs to hit the midol - how many times do i had to say "im not knocking . . im curious" Damn dude - you get off your pedestal

Everyone else has been really cool and having a real conversation - dont try to flame for no reason
