These cars seem to dyno higher in 3rd. Even the guys at the shop said to dyno it in 4th, so I did one in each to prove myself right. My clutch is already slipping because it was not intended to handle this much power from the factory. These cars have weak clutches from the factory. Believe me, I know how to drive a clutch, so it's not driver error. I didn't do anything for the dyno except drive it there, they strapped it down and started the runs. Everything is EXACTLY the way it came off the assembly plant. Stock everything.
Thanks for the responses.

I'm not sure what people will dyno with the stage 2 kit, but I'm sure GM underrated the stage kits just like they did the cars. I'm getting ready to do an INTENSE stage 3 kit (with a 2.6" pulley), the proper supportive mods, and a clutch next, I'm hoping for 275-280whp.

Wow! What is with these numbers!! I havnt dynoed my car yet so i dont know what it was stock! But i dont remember redlines dynoing that much stock when i first got mine almost 1 1/2 years ago! WOW! Ill have to get mine dynoed soon!! I wonder why the Cobalts are puttin down more than redlines?? Could it be operator error?? Cuz i know none of you can take this!lol jk

. I made sure of that before I left. For what it's worth, he showed me std and sae, and they were the same. The weather actually hurt me a little, because it was a tad lower before any corrections.

The ones he printed were STD. I got to see the STD, and SAE. STD figures everything for a 50 degree day. SAE Figures for a 70 degree day. There was almost no difference between the two numbers. When he showed me what it actually made today at that exact minute, it was a few less. I know you don't like these numbers because you have an SRT-4-but these are corrected.

Probably not the reason he was asking... There is some operator error there, probably fudgin' numbers to please customers.. I was gonna keep my mouth shut and not say anything but you opened yours.. A little too high for stock.. Cobalts and Redlines should only be at about 205-215 stock. PERIOD!

Get a life, and trade your ION in for a 2006 S/C Cobalt SS.

Let me say, you've got to get your blower done by them!!! You'll see an increase in air flow, plus the polished exterior rocks!!! Sorry for the advertising, but I think it's somthing that us cobalt/ion owners need to look into doing!
Anyway, time for the numbers. Both runs were made on a Dynojet, one in 3rd gear, one in 4th. Also, dyno sheets are posted below!
3rd gear pull: 232.7whp, 198.6wtq
4th gear pull:232.3whp, 196.9wtq
I want to re-clarify, that this is on a BONE STOCK S/C SS, no changes made from the factory-under 1700miles! The 4th gear pull was done immediately after, with no cool down. Like most of the ones I see, it starts somewhat lean, and is in the high 10s afr by the end. This is with a slipping clutch, it barely grabs anymore. I call it the "sponge". Take care guys.

Take care guys.My guess (post #30 in the following link) at 232 whp and 203 wtq wasn't far off !! I think I'm the nearest ... what do I win ? LOL congrats for the numbers !
