just goes to show ya, Gm techs cant read, no way people with these tight bolts had them tightened to 15 lbs ft like the instructions say. glad to hear its done

Xenozx

Thought I would share:

18.0 PSI ( I saw peak of 17.6, 17.8, 17.9 and 18.0) all seems random.

329 Crank HP (up from 303 previously before 2.8 inch pulley)

KR 0.0 until it reaches about 6500 RPM then i saw it go 1.0 0.07.0.03 all before I shifted at 6900. Is this normal?


All readings taken with my broken interceptor (picks and chooses when to display data, surprisingly came on tonight )

Matty

Nice!

2K5SS/SC?

Sweet. Great to hear the new pulleys are working out great!

Blown 4-banger

with 18 psi and 9.5:1 static compression. It equals out to something like 14.5:1 compression, thats pretty damn impressive on pump gas, only 1 degree of KR isn't bad at all!

Xenozx

Yea, and thats with the BKR6E's or what ever the #. I have the BKR7E's sitting here on my desk and I will probably install them tomorrow or something

Blown 4-banger

There you go! Problem solved.

TotalEclipseTinting

Sorry if you already said this, but does the Pulleyboyz pully work with the GM hub that came with your stage 2?

SS Gordon

YES!!

cvenom2122

thats the whole point of this thread!

good to hear bro what is that crank hp converted? we need to hit the dyno! and track! 100 octane mabe? lol

moose

what up guys?? gettin ready to order the 2.8" pulley, just wondering how long it has been taking everyone to get theres shipped.....i can't wait.......the stage 2 kit already was very impressive, i can only imagine how this will make it.........
my current mods are: 3" hi flow cat, 2 1/2 pipe, hks muffler, jbp control arm bushings, injen intake, irdium plugs, & stage 2...

one other thing can someone send me the link to were u can get the interceptor gauge at for a decent price....

Im really interested in seeing some track times, and possibly VIDEO of runs with a stage 2 and the 2.8" pulley installed. I can't wait to get this stuff installed on mine...

codyss

I thought I saw someone say that they got some surging when using the 2.8 w/Stage 2.

Any of you guys have this issue?

CTCOBALTSSS

Don't buy the interceptor gauge yet. They are having big issues with them right now. There are about 5 threads in here about how their Interceptor died. I would wait untill the issues are fixed.

SS_SC_Cobalt

I would expect if you order today it would ship today or tomorrow and goes priority mail so 3 days max

SS_SC_Cobalt

time for a little torco that will solve the knock, I was getting 0-.5 KR all day yesterday in the searing 90+ degree heat with 24lbs boost in my SRT

2006ArrivalBlueSS

Bro, I know you're excited about the new set-up, but the numbers you state above are a little questionable. I have the exact same set up as you (minus the exhaust and downpipe) and I got peak 253 hp on the Interceptor (when it works (lol)). 329 bhp is 273 whp. That sounds more like what Rob @ Intense is running with a 2.5" and HP Tuners. Not too spoil the party but the numbers sound a littler rich is all I'm saying. The boost numbers sound accurate though!! Did you get a reply from Aeroforce yet? Are they supposedly sending you a new unit?

Xenozx

Dood I feel you, but here is a video before I installed the 2.8 that shows 303 HP easy, may even have said 312 but gets kinda blurry at 16.3 lbs of boost.

Here is what my car was putting down with just an exaust.


Now IM sure that Neither the Inteceptor or that Dyno where 100% accuarate. There was a lot of drama in my thread with that dyno chart saying its too high. I agree from what Ive seen other cars put down, its a lot higher then it should be. Maybe I have a factory freak or maybe a sensor/dyno is off, but thats what it says. it was 329 in the 88 degree heat. I mean check my 1/4 mile? 13.8 at 105 w/ 2.35 60 foot? Thats a 13.5 or less 1/4 mile time with a good launch. How many people with more mods then me are hitting times like that?

I will be hitting the track up Friday to see what I can get down. I will hit the evolution dyno day up next time they have it too, to see what kinda HP I am putting down now. I will definately update as soon as I get that info.

2006ArrivalBlueSS

Cool...can't wait to see what kind of numbers you out down. And the Interceptor??

Xenozx

opps still broken. Its come on a few times. I talked to Todd at aeroforce, he says these problems are specific to 06 Cobalts. Says theres alot of noise in the power system that is causing issues with the LCD screen on the interceptor. Said a few other reports have come in. They are working on a fix and said he would get back to me soon.

cvenom2122

Got my pulley on also! im loving it! 4 mins total time took me more time to get the tools out then to install thanks pulley boyz!

More drama today:

Took my car in to the dealer and left it for them to loosen the bolts on the 3.0 ring to the correct 15 lbs torque. They first told me they could do that and it would cost me $50. After alot of argueing they finally said they could loosen the screws without charging me and also install the CAB's that have been sitting in my garage for over a month now. They originally quoted 1 hour labor at $120 (with tax) back when I ordered them from JBP. 6 hours after I dropped my car off they call me and tell me it will be $574 to install the bushings, alone, plus they decided they couldn't loosen the bolts now because they say they're supposed to be that tight (nearly 70 lbs measured with a torque wrench in my garage). If they loosen the bolts they'll fly off and be held responsible (BS, it says right in the instructions 15 lbs., if that's wrong, it's GM Performance that would be responsible, but it isn't wrong anyways). I argue the price for the CAB's and they come down to $374, then later tell me that they don't have the required tools to do the job (this is a dealership). The last I spoke with them they said they could put the new pulley ring on for me at $50 but could not loosen the bolts to 15 lbs because of liability.

Sorry for the long rant, but I've just totally had it with Bill Heard Chevy. What a wasted day...

Xenozx

Take it to another dealership. I had my CAB's installed at "Rhino Linings" here in Delaware. they have an exaust/suspension shop built into it and they installed the CAB's for 60 bucks. Said it took em 30-40 minutes.

did you use the vice grip thing to try to pry them lose with a second pair of hands?

SS Gordon

Well I guess this was my lucky day as I got my Torks bit back from the dealer that installed my STG2 & then I got home & had a small issue with the belt sliping while trying to loosen the bolts so here is what I did!


I had my son hold the 15mm wrench & pull twards the front of the car & this added tension to the belt and held the pulley so I could loosen the bolts one at a time as I had to keep moving the pulley to the clear area to insure straight insertion of the torks bit & it worked like a charm!


Plus last night I found NGK BKR7E plus at advanced auto for $1.99 each & I isnatlled them tinight also

I took it for a short spin & liked what I felt but I want to see what it does on the interstate tomarrow :

Thanks for all the input on installing as it really helps to have some one pioneer ahead of you to list the do's & don'ts


Now one question is will there be any long term effect on running this pulley all the time like on trips & day to day driving ???

SS_SC_Cobalt

I would seriously doubt you would have issues with the 2.8 and stage 2
