Beck's 2.4 S/C Dyno
Here she be at this point in time.
2006 Cobalt SS/NA supercharged 2.4L LE5
At this point in time my tune was pretty fucked up, but it was a dyno day so i showed up and strapped her down anyways. I was having an issue with PE when i dropped the pulley size but after this dyno i went to do some more tuning and figured it out.
Since this dyno my IDC has risen 10% (because of getting tuning issues fixed) leading me to believe that i would have put down another 10-15 horses easy had it been dialed in. but here's my baseline dyno for now. i'll post another one in the next few weeks after i get my tuning dialed in. My wideband took a **** on me for some reason so i'm trying to get that issue resolved.
Making 11psi on stock internals.
Intake Air Temps 105 degrees max (in this weather)
Run 1: 251.18HP, 233.85TQ
Run 2: 253.23HP, 227.75TQ
Run 3: 248.62HP, 236.49TQ
Roughly 100whp over stock


p.s. vote beck for march featured car!

im actually disappointed to be honest haha. cuz i had to post this dyno before the tune was complete and i know it wasnt its full potential. the AFR's were all over the place and was running way too rich in PE. after i also installed some colder plugs, got rid of virtually all knock lots of room for improvement.
haha, this is great...and the funny thing is...blake with his 6k turbo install is right about the same hp..264 is what he put down...lol
dyno again...x

awesome....we dont have to worry about clutch and such cause she is auto lol, so a lil cheaper, and tune will be done by the only 2.2l cobalt tuner in the country lol, who is local, tuned my manual 2.2 the other day haha
Nice numbers man, I just recently got dyno tuned @ Tune Time Performance in NJ and my final numbers on the Mustang Dyno were 230/ 190 which on a DynoJet would be around 261/ 216, and thats just with a CAI, custom dual catback exhaust, and one hell of a tune. So props to u with those numbers u put down man. What do u have for supporting mods?

maybe i'll look into some lower compression pistons and rods and drop that pulley a bit more

No it was running rich, the IDC is 10% higher now because we were running into a rev limiter so to speak in Power Enrichment. Now that the car is able to work like it should in PE, it's injector duty cycle has risen ten percent with an AFR of 11.5 at WOT
