Hey man, you're car better be able to beat a stock ss/tc!!

Oh yeah, and I'm coming to visit the family in AZ the second week of November. I'll come to you, that way it'll be broken in and I'll be used to driving it by then.

Indeed. Also imagine what someone couldn't do if those driver assists were disabled. Not trying to be argumentative, I just hate it when automakers shove all these driver assists onto their car, pretty soon the term "driver's race" will be replaced by "launch control/DSG shift algorithm/traction control's race". The LNF is a great engine with lots of power, don't get me wrong, but for the love of jeebus... let the driver actually drive the car for cryin' out loud.

I remember that edmunds test, I also recall someone saying Edmunds drivers are crappy, and that it shows that it's the car running that 14 second pass, not the driver. These are the same drivers that couldn't break into the 14's with the LSJ, and some members on here have come damn close to breaking into the 13's stock. Not sure if too many improvements to that 14 second pass are forthcoming, no-lift shift and launch control take away two of the hardest parts of drag racing.

Drivers not actually driving FTL . More powerful Cobalts however, FTW :

all you have to do is not enable the driver assist, problem solved

However based on numerous dynos, the LSJ's actual stock output is in the area of 255-270 hp, and 220-240 ft-lbs. So going off usual stock LSJ dynos its more like this...

LNF Rating = 260 hp / 260 ft-lbs
LSJ Rating = 265 hp / 230 ft-lbs

LNF has direct injection, VVT, and a turbo.
LSJ has standard electronic fuel injection, no VVT, and supercharger.

EDIT* If you look at the GM rating, it says 205 hp @ 5600 rpm. However just about EVERY LSJ stock dyno, peak power is made at the rev limiter or ~6500 rpm, hmmmm...
pretty much

Ive been driving stick for a long ass time and you say launch control is such a big thing, yah im not saying it doesnt help out but come on man we are not driving an all wheel drive car...Just like them we can still bog the **** out of our car, not release the clutch early enough, miss shift.... Really there shouldnt be no excuses from anyone racing a ss/tc and get spanked on the track because it isnt a advantage we are fwd!!!!

Pretty much, although I doubt too many people would want to. Why get crappy launches and have boost drop out when you can have the computer keep everything in line for you?

I think I understand what you're saying, so I'll say I agree to a point. I agree that the LNF should beat the LSJ down the track, but I wonder sometimes whether the LNF would do as well with the assists turned off. Yes, they can still miss a shift, but when your launch consists of "set brake, set clutch, floor gas pedal and watch revs hold at launch speed, let clutch out on green and go", it takes some of the skill required out of the equation. Not a ton, but it might be enough to decide the race.

I'm not even saying the LNF shouldn't be faster, just that I don't like that GM put a bunch of driver assists on what (IMO anyway) should be a driver's car.

ok ok I'm really confused now, can someone please get me some verification on how much HP and TQ the ss/sc actually come stock with, as in like dyno sheets or something cause I don't believe that we are pushing 230 straight from the dealership, cause if thats true then I'll be sitting at around 250 now and then almost 300 when I put my stage 2 in correct??? if it is correct then how come so many people with the stage 2 are only pushing about 260 to the wheels... I need some proof on what the acctual HP and TQ of our cars are please lol not that I'm saying you are all wrong.. I would just like some verification so I know

Stock was underrated... but the Stage kits seem to hit the money.
You will not be 300 with a stage kit... maybe 235-240. (edit: mustang dyno assumed)

i just test drove the mazdaspeed 3 the other night for the fun of it (had some time). this is the closest thing to a LNJ cobalt at this point, so lets assume those are equal. i found that the speed 3 takes a moment to wind itself up, but when it does it goes like hell. this is esp. true from 1st and 2nd gears. the LSJ is great because ive got all the power waiting the second i drop "the hammer". the reason the LNJ cobalt has no lift shift is that everytime you upshift you lose rpm's...and for a turbo car thats the kiss of death against a car as stout as a stage II + LSJ balt.

my 13.8 car will still take a 14.2 LNJ (and speed3), so im sticking w/ the supercharger camp!

_________
06 ss/sc, g85, s2, and a bunch of other stuff

MS3's have the power reduced in 1st and 2nd, so yeah, that makes sense.

and, the 260 of the LNF is a big jump from the 205 of the LSJ. you can believe that they are under rated all you like, but i'll stick with GM's number.

your logic is flawed. severely.

lsj. not lnj.

No matter what car you drive, you will have to reduce engine speed on an upshift.
NLS is used for a few reasons. In this case, between up shifts it holds the engine speed at a certain rpm, as well as modifies the spark timing to produce a more dense exhaust gas (not sure about hte LNF, but most cars do this). This causes the turbo to remain in a 'spooled' state between shifts.
The other reason, is that with the RPM set a certain level between shifts, it allows for more accurate gear changes, thus reducing driver error, resulting in gained track times.

also, what alot of people don't understand is that a supercharger can only be upgraded so much until u run out. idk how to describe it. but u can buy stage 1, stage 2, stage wtf, but sooner or later, u won't be able to run a smaller belt, pulley set-up. thats why alot of guys ditch the sc set-up n convert to turbo. turbo's have alot more potential for higher HP on smaller engines. thats what a turbo is used for. to create lots of power quick on a small engine. also, people don't understand that with a SC u get hp right off the line. so for a track car a SC is ideal since u basically create boost faster because its belt driven rather than turbine. get it? basically with a stage 2 u get 25 whp roughly. add meth, h/e, and full bolt-ons n u'll see more hp. look up blown_4_bangers how-to on porting ur SC. sounds like a coyote being sodomized, in a good way.

also what is VVT? sorry, i haven't kept up with the "LNF" times n gossip.

Do what the turbo guys do when they max out their turbo... get a bigger compressor...
So that's what some of us are looking to do... HTV1320...

Variable valve timing... like on the LE5
