Thats cool.I did read on net that there is a stage 5 something like 23lbs of boost.Arp head studs ovecorse..

 

Not sure about a "stage 5." But I did hear a rumor about a stage 3.

 

mmmmmm stage 3.........

 

It looks like stage 1 by itself (no pulley) doesn't give much of a real gain in performance, but it definitely sets you up to take advantage of the pulley in stage 2.

My question is this...

Doesn't stage 2 use a 3.0" pulley, or did I hear that from a bad source? If GM is shaving 0.7 seconds off of the 1/4 mile time with a 3.0" pulley, just imagine what would happen with a 2.8" pulley. We're talking about possibly shaving a whole second off if you can hook it up right. If you can run a 14.5 in a stock SS/SC, then get stage 1 and a 2.8" pulley and you're gonna be running a 13.5 or so, which will put you in the same league as a Camaro SS, new Mustang GT, GTO, SRT-8, etc. Just imagine the look on the face of guys driving those cars when they can't outrun a Cobalt that's only had a grand or so spent on upgrades! I can't wait...

 

In the Pics there are part numbers for:

Stage 1,
Stage 2,
and Stage 1 to 2.

The P/N for 1-2 is under the PN for Stage 2.

Everyone is talking about these stages and Im just as excited as everyone else but stage 3 is what I want. And I am curious if the stages build off each other cuz ill get stage 2 begining next year and than upgrade to stage 3 when it comes out. HOPE it can work like that, if not just gonna wait for any word on stage 3.

 

also did u guys see that it says something about like 30+ peak power for s1 and s2, would that mean that if u get s1 u get 30+peak power then u upgrade to s2 and get ANOTHER 30+power?????

im thinkin it's either u get s1 or s2 and both will give 30+ peak power.

 

Stage 2 desc says it adds xxhp from stock.

The Pictures tell ALL!!!!!

Check my thread I started about Stage 3, I got proof that it exists.

-Rich

 

As of right now all part numbers are inactive.

Looks like these kits will be well worth the wait, now will will just have to see if they will be well worth the price?

 

Did anyone else notice that both sets of hp/tq numbers listed are over stock. This means that the stage 2 only gives 5hp and 13 lb-ft over stage 1. Seems kinda weird to me.

 

when will we be able to buy them?

 

I LOVE you GM!! When do part ##'s come out? I want now!

 

dont you mean the parts , the part #'s are there already

LOL

 

Stage 1's HP increase is going to be from the increase of redline RPM's. The larger increase in torque from Stage 2, will be from the smaller pulley increasing boost.

 

looks like what I will be doing is buy stage one then add my own pully ....unless the stage two increase is only like 100 $ more (canadian) tahn stage one.

 

Go to Revitupmotorsports.com they have a 45HP gain kit.Sorry no lazy link...

 

Sorry about that big typo there. So are you saying we can get the kit already?

 

Yeah but that's a piggyback system. The stage kits from GM are ECU reflashes which is a warrantable upgrade.

Also, my understanding is Stage 1 will be priced according to that stand alone upgrade. Stage 2 builds off of Stage 1 so that will INCLUDE all upgrades under Stage 1 and then will add the pully upgrade and reflash again. So, yes, one can opt to go directly to Stage 2 and I think this will be the same for subsequent stages going forward. I am ALSO a firm believer that Stage 3 exists however I think GM is having some testing issues which may be why it wasn't launched at SEMA. Stage 3 should be close to their concept car of 272 hp since it's only 21 more hp than the current Stage 2 that will be made available in Q1 2006.

 

It is a piggy.It probly voids warrenty.

 

There are actually THREE part numbers!
17801947 for Stage 1
17803229 for Stage 2 (includes all of stage 1)
17803230 for upgrading Stage 1 to Stage 2 (so it can be done at a later time)

HTH
WOT

 

Thank you, I've said that before but no one seems to listen... Its posted right there in the pics themselves.

All I want is the damn price on stage one! Come on GM!

 

So is the ECU reflash is stage 2 going to be different from the the reflash in stage 1? I think I would probably want stage 1 and then get my own pulley (as small as possible) if the ECU is the same.

 

It sounds like the flash is the same as stage 1. So I would be doing the same thing you are, buying stage 1 and adding my own pulley.
