Well I guess there isn't anything wrong with upgrading the springs and retainers to be safe.Maybe if they went with stage 3 or 4 then they would of had to change those 2 things right away.

 

oh definitly. Stage 3 and beyond requires new springs.

 

the upgrade is more about longevity then mere power. sustained high revs over long periods will have an effect.

stage 1 cams are good to 6.8k stage 2 is good up to 7.5k.

 

hes still going to gain some power from the cams anyways,not saying it will be a 100hp gain,but someone here in Illinois actually redid the cobalt's 2.2 motor and its a 2.6 now.

 

who's that? can you het me a contact number? i'd like to discuss boring out the sleeves.

 

mother ******, i just checked comps website and the cams my friend got off Red_Line_Cobalt werent stage 2, only stage 1... he lied n ****** sold him stage ones. i was wondering why his car didnt idle like mine first did

i hate to have to break the news to him

 

You might know him actually,his name Is Steve lives in Hawthorn woods,close to libertyville and buffalo grove area

 

can't wait for the vids. i want those same cams. what are the part numbers. my new job can get comp cams with a discount. discounts ftmfw.

 

never met but i want to now.

"- Street & Strip (Stage 2) Applications power from 3000-7500rpm .440 intake and .436 exhaust valve lift, 258 intake and 262 exhaust duration advertized (216 intake and 218 exhaust @ .050" duration) Requires computer modifications"

pulled from the turbotechracing website this is their comp cam description.

 

now dont forget those are only statistics. That power range is an average of where the power usually comes alive.

 

i just realized that it was for a 2.2. o well. i still want comp cams for my 2.0

 

6.8 to 7.5 is a pretty big difference imo regardless of statistics especially given these cams have yet to be dyno'd.


not trying to beef with you but that's why i'm waiting to see how these cams dyno.

 

well hopefully we can see a dyno soon.As for the guy Steve he is on here actually or was but I believe he was ban lol,here is his email though stephanjamesr@hotmail.com

 

I tried racing a ss cobalt on my way to work today but he shook his head at me no. So...

 

The zip tie idea is brilliant, That could be why almost EVERY time we need to hold the timing chain at work, on numerous styles of engines, we use them. they are cheap, and easy to use.

 

damn that's another post for the zip tie mod. zip ties ftw!......

 

This is from Comp Cams
http://www.compcams.com/technical/ca...12-117_226.pdf
2600-6800RPM

 

He probably doesn't like to race.

 

Bull LOL he had a Tach and a Shift light the size of a street light )

 

Well you would of had a better chance of beating him honestly,and he probably figure"I better not race this guy with a modded cobalt"lol

 

Here are the dyno sheets to compare the bolt ons before tune and after. Then went i get the car dyno'ed with the cams we can compare. And since everyone wants to see number's heres a start.

This is Bolt ons before tune


Now this is bolt ons with tune (NO CAMS JUST BOLT ONs)


if you look at the second run on the 2nd dyno sheet it looks like i drop hellas it was a different tune

 

that isn't to bad of a gain there,with the cams you should be up some more with hp and torque.You should get headers next at least,unless I am really blind and you have it listed lol.

 

i waiting for it to ship. it's clear images 4-1 header and im getting the new down pipe

 

those are the specs on the stage 1 cams check em against the numbers for stage 1 on the ttr site.

"Street (Stage 1) Applications power from 2600-6800rpm .423 intake and .419 exhaust valve lift, 252 intake and 256 exhaust duration advertized (210 intake and 212 exhaust @ .050" duration) Works best with computer modifications not required."

wow dude, do you even know what you brought?

 

oh ok thats why I was wondering with header and new downpipe,usually the header helps out quite a bit.I have to wait until August to get my downpipe for my stainless steel pacesetter header
