few pics of my car on the dyno from the so cal ecotecs meet at whitfield racing. nice to get a before and after comparison as i'm rebuilding my top end after this. and yes i am aware my car is running pig rich right now. just haven't had the time to tune and with the new goodies goin on at this point i'm not too worried about getting tuned until everything is done










and now for the dyno sheet:

 

Which mods do you have?

 

zzp stage 3 sc kit (60s, 2.9 pulley, s3 h/e), opt b, dual pass, k&n typhoon CAI, zzp LTH w/catted DP, tsudo 2.5in cat back exhaust. 91 oct. i think that covers it for performance mods on the car

 

Damn... Your starting a m90 build right?

 

Who tuned you? You oughtta throw some meth at it and let Steve get a hold of it.... It'll turn into a whole new animal..... ask me how I know..

 

did you do all those mods without a tune update? Cause with your mod's you should have put down more than that! ive seen stock pulley LSJ's(factory freak i guess...?) put down just shy of those numbers! what were the conditions like? Super hot? I know it was where i live! 95+

 

It was 94 out when I dyno'd. I'm on a canned tune from zzp. And yes I am doin a mp90 build. I've git the ported mp90 sitting in my garage along with stage 2 zzp cams, zzp valve springs and retainers and an ais meth kit runnin dual 14gph nozzles. And a spare head. Just need balance shaft delete kit, ls4 TB and a few washers. Steve us gonna tune me when I'm done. Shooting for 400+/350+

 

yea i was there too it was hot as **** and my numbers on 09 cobalt ss with bolt ons was only 250 hp and 295tq lol

 

09sscalicobalt what hood brand do you have? And I hate when I have to dyno people in temps above 80* lol

 

extreme dimensions carbon creations oem cf hood

 

Eh, I ordered the vis Carbon fiber hood. Hit two deer lol

 

haha damn well we dont have deers around here but ive had it and love it also have matching oem trunk and oem ss lip too melon aka jon has the same hood/trunk too

 

Sweet **** man. Yeah I hit two at the same time haha one attempted to jump over my car and it took my passenger fender, my front bumper, and hood out along with denting my intake for my 25g

Then another deer attempted to jump over my car "roof" and ran right into my damn door lol

 

i was thinking you were on stock pulley cuz your exhaust is loud

before my chambered muffler it was str8 thru and couldnt hear my 2.8

 

My exhaust is retarded loud. But I love it

 

loud indeed.....

Jame quit herding deer, Im sure there is a better job for you out there lol

 

I've got the videos but don't have a YouTube acct to load them to so can't figure out how to post them

 

make a jewtube account or upload it to photobucket

 

**** two at the same time lol, you have to be unlucky Gives you a good reason to get a nice hood tho!

 

fine! its just video of the pulls. no graphs or anything, that was already posted in the OP

233whp???

you needz a tune ASAP

 

lol yea i know. but almost pointless to tune at this point. i knew i was runnin that rich and figured that would be about all i would put down. i figured 240/220 so i wasn't too disappointed. i know i should be up around 260ish given upgrades. have hp tuners but computer battery is shot so need to get a new battery before i can tune anyways

 

shwew. i'm on similar mods except 2.8" and no catback exhaust, i'm hoping to put down somewhere over the 240-250 whp... granted i need more cooling mods and a good tune yet as well

 

totally obtainable with a good tune. as the graph shows i'm running a 10.0 afr. with a leaner 13ish afr i'm sure i would hit around 250-260

 

not only afr but probably your timing is on the ground too. theres deff plenty of room for power, and easy 260whp
