Dynoed the 2.2 Ion on a Dyno Jet yesterday. Pretty happy with the results. Nitrous wasnt firing for some fucked up reason so I only have n/a numbers for now.

Mods:
Fujita CAI
LSJ exhaust manifold
LSJ DP
2.5" Catback w/o resonator

Zex 75 shot

Nice numbers, and the car sounds really good!!!

14:1 A/F at WOT, man these things run lean.

xCobalt05x

sweet, i hope to get my first dyno run in on the 26th of may.

Where in Santa Clarita was that at? I'm up in Bakersfield and we have a dyno up here.

bc3tech

yeah the ecotecs love being lean. granted, he's not boosted but some are doing low 13's boosted.

YellowLT

Damn that thing is jumpy.

i cant see anything while im at school, so what did the numbers come out to be

oldsskool

Hmmm why are your rims white in the vid and black in the pic?

Good numbers!

XM15

+1 I'm at work, so neither can I. What did you put down?

QuikSilverSS

The dyno sheet shows the Torque and HP jumpy throughout the rev range, what could cause this???

YellowLT

Crappy Stock tune. Over worked Injectors. Shitty A/F ratio. Take your pic

can someone tell us what the numbers are

Dustin

135/139 ish

06_ion2

umm no its called smoothing... lol its at a 3 if he wanted a smooth curve it would be at like 5.. if it was at 0 it would be spiking alot more and maybe reach about 5 more hp

DO WHAT??? Thats exactly what I put down bone stock!

My stock dyno tread

Is yours automatic?

XM15

^^^Chris, what dyno did you use? Those are great numbers! Thats pretty close to what I have, and I have a CAI and full exhaust!

ChrisAult2004

It was the Dyno Jet at Precision Auto Sports in Beavercreek OH. I must have had a factory freak or something lol.

IonFeright

Yeah without the resonator it sound pretty kick ass. Neighbors hate it

Yeah these things do run lean. The dude who owned the shop was afraid to even run the nitrous. It didnt work anyways so he stopped complaining.


Yimmi motorsports.....something like that. Its a Suburu garage with a Dynojet.

Because edgeracing.com licks big fat donkey nuts. Ordered the wheels 3 months ago and still waiting on 1. Ive had my KDW's collecting dust so I bought 1 temporary rim.

I agree...the Cobalts are putting out 132-137 stock, yet you have 4 mods, that potentially could bring a cobalt into 150's range? what gives? is the Ion not rated at 145hp ?

yellow_cobalt

exhaust sniffer. doesnt give you a true reading. if they used a wideband, you would see the ratio drop off quick and be quirky.

Stl06LS

The exhaust sniffer on a dyno is a wideband o2. But, being further down the exhaust flow and going through the cat, it can be 1/2-1 point leaner than near the exhaust manifold.

NextLevel

Humidity and air temps play a large role in N/A dyno numbers, you guys may have run yours on a colder day.

yellow_cobalt

yeah, i replied too quick to that and tried to in layman's term once again (two seperate terms so some could distinguish between them)

ChrisAult2004

91 degrees with 80%+ humidity.

IonNinja

I think any Cobalt dynoing in the 135 range bone stock is a BS dyno because 145 crank HP only comes out to around 120whp...Seeing 10-15wp more than that is suspect. His #'s are right on for a bolt on 2.2.
