I was gonna have my car flashed with the stage 3 cal, and the calibrator told me that because it is an off road cal, that it disables the a/c. I don't know about you guys, but I have already bought a second ECM so I can have the stage 3 flashed into it and swap it in when I go to the track. Other details is that this cal bumps the redline another 300 over the stage 2 and that it comes with a 76mm pulley. Also, it has algorithms to recognize and handle NOS. I'm stoked. It is supposed to be hitting the market any day now.

Yeah, that's been discussed already.

S3 is gonna be a separate ECU anyway, so why not wait until its released?

 

any horsepower and torque numbers for this kit compared to the stage 2 kit?

 

If its anything like what the time attack cobalt has these could be possible specs:

"2.0L ECOTEC with GM Performance Parts Stage 2+ kit, larger injectors and 77.9 mm pulley

264 hp @ 7000 rpm (344 horsepower @ 6800 rpm with nitrous boost)

230 lb.-ft. of torque at 4000 rpm (350 lb.-ft. of torque @ 3600 rpm with nitrous boost)"

Interesting..

 

What is NOS?

 

read my sig

 

Thats pretty funny.


Amateurs don't use NITROUS OXIDE! I've seen the way you drive... you've got a heavy foot.

 

NOS is a company (thanks f&f stands for Nitrous oxide systems) but it is nitrous oxide.... I hate when people say nos..... aaaaagggh

 

... that cant be very safe for internals ......

some good info tho

 

actually, people have bumped the redline to 7400 without issue

 

Now me and the mad scientist gotta rip apart the block to replace the piston rings u fried!

DANGER TO INTAKE MANIFOLD

But personally I hate nitrous...I had it on my neon and I loved the boost...hated how it was temporary.

 

ask any racer any real racer it dont matter if you win by an inch or a mile winnings winning. lol
sorry i had to. Im excited abotu stage 3 especially with a gm employee discount. my service manager is supposed to get me the new rotors paid for by warranty,.

 

wow sounds like something worth looking into

 

Going from a 3.07" (77.9 mm) pulley to a 2.99" (76mm) pulley seems kind of pointless. I assume that since it is off-road only there will be no warranty which combined with no a/c and only a .08" difference in pulley size I say it is pretty much worthless. Just spend the money on HPTuners.

 

"Was that fun" lol

 

The intergated Nitrous setup will be nice too

 

I can disable the AC with the climate controls in the cabin

Maybe remove the AC might help with weight and cooling properties

 

I"m runnin a 7400 rpm redline... no problems, and the shift light on my dash comes on at 7200 ? wierd. and I"m just waiting on my 60lbs... 50 shot here I come

 

I thought stock valve springs were only good up to like 7000 or 7100 rpm? If we went to 7300 or 7400 rpm wouldn't we float the valves?

 

probably but it isn't doin it yet... I"m swappin cams soon anyway... I also shift at 6800 I just hated the stock limiter

 

The GM performance book says the stock springs are good up to 7500rpm...

 

^^^ Hmmm,

"Good To" does not limit the lack of premature breakdown...

 

Exactly! ^^^ The valve springs in my truck were supposedly good for 6500 rpm, but the cam stopped making power at 5500 so i never went above that. I did a burn out and accidentally over revved it and it floated the valves at 6000!

 

Any price yet?
