Stock Hp: 112.2 @5335
Stock TQ: 117.2 @4089

Just over 6000 miles on an 06 Cobalt 2.2 5-speed with the only change being Mobil 1 Synthetic.

 

Mustang Dyno meter sucks. Try a different Dyno like a Dynojet. More accurate results. On a Dyno jet I bet you would see about 130whp.

 

yea i would guess 130 as well

not bad, almost as much torque as a civic Si

 

As far as the dyno-meter accuracy between the MD and DJ.......
Performance shops use little tricks such as changing the vehicles weight input (even a hundred pounds will skew the numbers quite a bit) to show the part they just sold you did something for horsepower gains.

I dont have a problem w/ either one, they are both industry leaders, the main problem is inept or corrupt operators. If you go on a Load Control Dyno, your car better be weighed, with the person in it doing the testing. Go over all the parameters with the operator to make sure you are getting what you paid for. Because if the parameters are set correctly on both dynometers the numbers should always come out within a few hp frome each other.

Keep in mind though that the Mustang Dynometer is a true loading dyno that uses eddy current motors....so I would trust the numbers to be more accurate than a dynojet which uses simple inertia to measure power levels.

 

Funny you should say that sethallen. Brand new civic si was up just before me and I actually made 2-3 ft lbs more than he did only at a much lower rpm than him. He also made 15x horses at well over 7000 rpms. Just a vast difference in how the two motors are designed. But I paid about half of what he did! Oh, and I thought 112 was about right given the drivetrain loss. Can't imagine I would only lose 15 hp from flywheel to tires. 130 would be nice but I don't think the little 2.2 can put that to the wheels stock.

 

i think around 120-125 has been average for a stock dyno on hp

 

and welcome to the board bluebaltls....i see ur from bama to....you just missed our meet here

 

yeah, on a dynojet my old 2.2 automatic had 117 whp 119 tq..

 

my 2.2L Ion pulled 122.42whp, 127.92wtq w/ cold air intake, exhaust, ported throttle body while turning 18" wheels.

 

Thanks for the welcome 5 sedan.

 

your welcome...always good to see another bama person here

 

I don't want to sound stupid, I know a good bit about cars, but if the 2.2 is rated at 145hp 155tq why dont you get that in the dynos?

 

manufacturers get their hp ratings from the crank not the wheels,guys dyno to get the (TRUE) numbers to the wheels.

 

explain this to me please. this is one area that confusses the hell out of me.

 

Crank HP is how much power the car can make without delivering the power to components (meaning just the motor itself, nothing else connected) such as the tranmission which then delivers to the shafts and then to the wheels eventually. During all this hp is lost whether it's to the front of the wheels, back of the wheels or all of them when engine hp is delivered to components (i.e tranny).

Wheel HP is how much power the motor is putting down connected to components such as the transmission which delivers the power to the shafts and then to the wheels.

An accurate estimation of how much your getting to the ground is determined by a Dyno.

Dyno's are never more then 5% off unless operator error. Scenarios change often. More or less weather conditions dictate how much a car can put out in that run.

 

another question...how much horsepower would i get out of a aem cold air intake

 

i woudl say approxmently 6hp...but every engine reacts diffrently

 

i'm confused...people always tell me 15-25hp

 

one more thing....its troubling me on weather or not i should get a AEM cold air intake for x-mas...for about $250....

any other worthwhile spendings for that much money...any help would be appreciated

 

AEM is totally worth it. I have one and love it.

 

Well.....i dont have the scan yet of the sheet, but i dynoed my car on wed with an intake using DynoJet and the numbers read 128.6Hp and 138.6Tq........i was happy....and i know i am not getting jerked around because of the reputation the shop has.....

 

You're putting mobil 1 synthetic in a 2.2? I thought mobil 1 was for the SS/SC models

 

the 2.2 can take synthetic after around 5000 miles

 

I use synthetic in my base model. It's got plenty of miles.

 

wow.... 112 is really low....
