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

nice numbers beck!

 

nice number and great job on the build

 

dang that better then me i think!!

 

real nice numbers..WANT VIDS!!!

 

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

 

woot nice numbers.. makes me think twice about not wanting to get the m62 lol

***** :-P

 

this we already know...

 

we are going to sc my gfs 2.2l auto here once we get parts

just outa curiousity...how much did this cost you in all

 

bout 3,500 including all gauges, clutch/flywheel etc etc.

did all the installs in my garage, tuning was done by a friend of mine.

 

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?

later

 

Fujita Intake, Pacesetter header, Custom downpipe, 60lb injectors, Cobra Heat Exchanger, Dual Pass, 3" pulley, 4.2L throttle body

runnin stock catback exhaust at the moment.

also a lightweight fidanza flywheel and a spec stage 3+ clutch

 

nice numbers, love the car, u got my vote for COTM

 

Why did the SS/SC not come with a SC 2.4 motor with Beck's setup? 11psi and 250+whp is very impressive. Nice post!

 

haha no more shittin on this 2.4 i'm still well under the efficency range for the blower too.

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

 

im jealous lol

 

Nice numbers

 

you do realize that if you were running rich your idc's would not be higher now, you were probably running lean if they are higher now

 

We have so many options it's great

 

Nice numbers Beck; and congrats on this build.

I still gotcha beat though! lol

The two sexiest black balts on this site, we gotta be in constant competition lol...

 

aye steven ur from oak park? in sac? or is there a different oak park?

 

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

 

Jesus. Got torque?
