GAGT vs Cobalt SS

[FORTEEN3GT]

GAGT + Blower (only) = 14.5's

GAGT + Blower + TM Tuning + Tuning = 13's!!!!!

read up dude! Tuning is the key to performance from forced induction.... the Torque Management alone is worth a few tenths off the 1/4

That's a horrible comparison. Like fourteen3gt said, tuning is the key. Considering the CobaltSS comes factory equipt with a supercharger, I'm sure GM has "supporting mods," and the PCM tuned for it already.

Better comparison....Monello's car (S/C, DHP, SLP) runs 14.1 with 18 Eagle 077s. And if my memory serves me right at the DHP dynoday he dynoed 217whp thats about 270 at the crank. I believe this was done with the stock 2.8 pulley for the magnachrger kit.

My car with other supporting mods, dynos about 60whp more and runs 6tenths faster. And after i get my comp cam in her i'll dyno again and post pre/post results, as well as some new times to come at Pontiac Natl's.

keep in mind that this was when DHP was just starting to play with the GA and i think the tune was on the conservitive side cuz of some false KR issues going on.

14.5 is a little optomistic. When my car had the blower only and SLP exhaust I was typically running 15.1-15.0... best I did was 14.9 running with the air box out straight into the MAF. I had to get a CAI and random tech downpipe as well as a DHP transmission program to get to 14.6. Then other mods to get down to 14.4 before the trans started going. Regardless, you hit the correct point. The car always runs better with tuning and the cobalt is tuned from the factory to run boost where the GA isn't, so naturally the GA will need tuning to run better and to even make a fair comparison between the cars.

of course tuning is the key! and of course the cobolt has supporting mods of the blower... you compare a ga to cobolt ss, i said with JUST a supercharger its still not gonna blow the doors off, you can tune the cobolt too and make it faster i would imagine as well

true, but even giving the cobalt a good tune and some tires, I know it's not faster then some of us on the board.

It'll damn sure give you a run for your money!


Hopefully somebody will come out with some computer options for the SS. I think there are alot of doors to open with the re-work of the stock computer.


*side note: Why is there all of this comparing a modded car vs. a stock car. I hate it when people do that.

because it makes me D1CK bigger.

After my M90 is installed and my A/F is tuned just like the Cobalts is from the factory i will gladly go race and beat one and my car weighs 3600 lbs. Have only sen the LS models driving around but maybe when I am blown I will get lucky.

The cobalt gets worse and worse looking each time I see them plus they stole the lights off the Impala.

no they didn't.. they didn't steal the lights off of the impala... if the lights resemble anything, they resemble kinda the Skyline. and the impala's lights are a ripoff off of the skyline too.

I hope you put up some damn good times on your first run at the track. They better be better than mine. If you don't break 13.8 in three runs or less, I will be severely dissappointed.

[FORTEEN3GT]

with an m90... he should hit 13.7's with tuning! even with 3600lbs..... the added compression alone is good for a tenth or two!!

[clark75]

13s Might be tricky with no LSD and a 2.86 FDR with only 5 lbs of boost.

no way he would do this with a 3.8 pulley... minumum 3.4 which is 8psi.

If you guys are refering to the round tail lights, I think chevy has a car that has had the round tails for many years. What's the name of that car again................oh yeah, Corvette

yeah the impalas and cobalts taillights definitely don't resemble the corvettes taillights very much... ESPECIALLY the impala, humongous and round definitely a skyline thing... and the skyline has been around for about as long as the corvette too...

3.4 is 8PSI?? Thats news to me since the M90 is rated at 7PSI with the stock 3.8 pulley. Everyone I know hits 10PSI lightly modded with a 3.4 pulley.

Also, there is no way he can run a 3.4 pulley without some MAJOR mods without knock. I dont care if gods finger touched his PCM and commanded it not to knock. It will with that bumped compression.

He will either need an intercooler, or a cam to fend off knock if he wants to run a smaller pulley. And since he is using a 3400 engine, I dont know if the current intercoolers on the market will work.

[3400Impala]

To start I will have these mods- custom exhaust- hollow cat to muffler, no piping, custom fwi with 9" k&n filter, L67 throttle body (69mm I believe), ported lower manifold, dhp power tuner, intense motor mounts and ffp under drive pulley. I may port the supercharger slightly as well but more just to clean it up a little bit. After a couple months I will be getting a stage 1 cam and heads from milzy and then TOG's or S&S headers. Once I have heads/cam/headers I will be getting forged pistons to lower my compression and then look to raise the boost to 10 or 12 if the scan allows me to do so safely.

To be safe I will be starting with a 4" pulley and as the scanner allows I will be moving down to a 3.8 and scan and tune once again. For the first couple weeks I plan on having a scanner and laptop hooked up at all times, my goal is not to just slap on whatever pulley and see how much boost I can run, its just to get things running and properly scanned and tuned and then adjust the pulley sizes as needed.

Was really joking about the whole tail light thing I don't care at all just don't like the cobalt much, I guess its just a girls car to me.

[KPimm]

Brandon, have you talked to Milzy to see if he has any cams for boost? I know he was talking about making them when he first started the cam project, but it would be good to get one that would compliment the M90. If you're going to spend all this money, you might as well do it optimally.

[3400Impala]

Yea I have been in contact with him and will be purchasing a good cam a couple months after the s/c is on, unless I get very patient and just wait another month or two and buy the cam/heads from him and install everything at once. That would be pretty hard with the supercharger sittin here on the floor for that long .
