o dang lol i didnt even look at that. fyi im canadian too ahaha so not all canadians wont be celebrating ;]

 

lmaoo thats just trippy but yeah im most likley going thursday morning..**** school

 

good call thats wat i always say ahaha

 

yup dyno is deffinitley more intresting then school and listening to some rando's talk to yu about how their university is better then the others lmaoo university fairs suck *****

 

well i got the car dyno and im extremley pissed off, I LOST 11 WHP!!! basically everyone was wrong! this is total bullshyt. the place i go the dyno done says i have no back pressure and i went to another shop and the guy unfolded the graph sheet and right away sayd yu ahve no back pressure i unno wtf is gong on but im pissed!

 

wow...

 

Having no backpressure isn't what hurts. You don't want backpressure. With an exhaust setup that minimizes backpressure, the powerband will be shifted up, so the loss of 11whp is puzzling. Probably the dyno and conditions.

 

go back and backhand the guys that told you the problem is you have no back pressure and then tell them they're stupid

 

well if its not backpressure wtf is the prob?? and the dyno was done in the exact same place with same conditions

 

I wish I would've skipped the GMPP stage 2 myself... all I have left of it is the damn HUB!

 

thats not the problem right now lmaoo

 

I think you'll be lucky to see 10-12 whp with everything without a tune.... the stock tune is what is holding you back... I did a full header, downpipe, 2.5" exhaust with crush bent piping and when from 241 and 229 to 261 and 232 and then after meth and pulleys and 3" exhaust I don't know where I am at now!

 

i unno if your confused or if i am but did you not see the post where i sayd i LOST 11 WHP!!

 

OH... HA HA HA HA..... that sucks but I can see it too!

 

you sure you don't have an exhaust leak?

 

nop already checked that another cobalt owner gave me a method of figuring out how to do that and he sayd its fine

 

whoever was running the dyno has no idea what they're talking about. and the guy at the other shop either. just seems weird that they both would have no clue, and both give the same bs reason.

also keep in mind that dyno #'s are completely worthless unless you're tuning. said it a million times, you can go to 10 dynos right after the other and get 10 different #'s. it means absolutely nothing.

 

if you had a leak you would hear it.
loud hissing in the car.
or it would just sound brutal outside of the car, more so when revved.

backpressure isnt the case here.

you should loose some low end and gain up top.
youve lost about 11 hp.

cant say ive seen this happen with any other exhaust bolt on system on a stock tuned/pullied ss....

dynos are a tool yes.
a tool to view what is going on with your car.
in this case his stock run was normal
now the dyno says otherwise.
regardless of what was made stock, the point is he dynoed in similar conditions on the same dyno and his numbers depleted.
odd.

 

put some 42's and a 3.0 and u will re-gain that power and then some

 

im buying the ott stage 1 kit when i get sum money so im not worried about that, im just pissed off because you spend all this money on products that are suppose to make your car better in performance but are really slowing yu down!

 

well u dont have anything but exhaust. the cars not puttin anything more out the back.

 

i dont get what your trying to say?

 

ur exhaust is prolly too big threw out need some back pressure. u basicly need to free up the front end some and u will gain most of it back

 

100% wrong. backpressure robs power, and you don't want it.

 

yeah its what was attempted but thanks to spaghetti headers it didnt really workout!! and if your saying piping size is to big, its 2.5 so its not big at all

i heard our car needs some backpressure to run good??
