Do the stationary dynos give you the best HP numbers? The car's not benefiting from all the air flowing to the intercooler is it? I just wonder because I've run 233 HP with my G-tech stock. Granted it has more margin for error especially since its not in as controlled an environment as a Dyno that's inside a garage. I recently installed a K&N Typhoon and will do some post mod runs once the weather out here drys out.

Some more FYI for you guys, "typical" mods to the cobaltss will NOT gain you as much power as a similar mod on another car. This engine is very good from the factory, to improve upon it will take more tahn what you normally would do to increase power. SO, an 8hp here, 3HP there, eventually will add up to a fast car! Don't expect a 20hp gain for 200-300 dollars, EXCEPT nitrous
Nice testing by the way, very informative!

You also have to take into consideration the HP gains as a percentage of what's there to begin with. When I had a 5.3 liter V-8 the base HP was about 285HP after adding intake I saw a gain close to 300, 15 HP gain, that was a little over a 5% gain in HP. A 205 LSJ (yes we all know its under-rated) with an 8 hp increase, that's about a 4% gain. So these numbers aren't very far off. Any increase in HP of 10 or more from just an intake is about par. Besides you also have to remember, a 10 HP gain on a light car is better than a 15 HP gain on a car that's twice the size.

For anybody not impressed with that really needs to go back and compare the TQ curve between stock and the last dyno with all the mods . Most noteably , check out how fat it got between 3200-5500 . Peak figures are SO many times decieving , so many people cheat themselves by just paying attention to the peak gain .
I bet DOC feels all that TQ in the low RPM's driving around town .
TXRLU - When you dyno a car , their is a LARGE fan blowing on the front of the car to mimmick the air you get while driving the car .

oh yea, I feel the torque...and yea, the fan is huge, almost as tall as the car with the hood open.
Funny thing, this was a 'mustang' dyno day. I snuck in and I actually had better numbers than a few of them. Although, they did a tune, diablo sport hand held, and they guy got 40hp/tq....I cried....there was a cobra that made 480hp and 550tq....mean, very mean...

.....too bad you couldnt of had a stg1 pcm tune in there too . GM claims 31 hp on stock engine , with the mods like you have I bet youd match or surpass that 40 hp gain the Mustang got
The 03-04 Cobras are just sex on wheels period , before I bought my shell of 94 Z28 ....I thought long and hard about turning to the dark side . I just couldnt bring myself to do it :shrug:

so i gather from this you are happy with the injen CAI and would recommend it?
im short on cash for the time being and am only looking to upgrade the intake. from what i have seen, the K&N and others do not give the same hp/torque gains, correct?
and nice numbers, certainly inspiring. since i am relatively new here, do you possibly have a link to exhaust sound clips? the performance is one thing, but the db's and throatiness certainly have an appeal aswell.
thx

As far as exhaust sound clips, check out the 'official exhaust thread' in the 2.0 section. The first post has them all in one place.

I have been testing and fooling around with this CAI thing. It seems after you put a high flow CAI on my car the dirst inside my oil increased. This must be true then. Is it worth it to spend big bucks for a few small horses and let dirt get into your engine? My idea of a perfect set up would be for my Cobalt to run strong, clean and fast. Is there a solution for this....?

So im not sure if i understand this completely but if i buy a Injen CAI. this will let more dirt into my motor? I didnt think injen was that retarded if this is true. because i had a Injen CAI on my 2001 Cav z24 and it was great i loved it

Well, I am happy. I got 216.5 on the first pull and 215.9 on the second. Both were 4th gear pulls.
On another note, he did an 05 a few days ago and he got 197.4 as a best pull.

Looking at you dyno graph, I would say your car is going rich at around 2800rpm which is why you have that dip. With a proper tune you can probably pick up another 10-15HP.

I'm going back next week to do a few more tweaks and see where its running. With 20's I had 248hp and 240ft/lbs. The IAT2's were high as well. I tuned it for 5 hours on the dyno too.
