Is anyone not seeing that it's GMS time attack Cobalt there? I highly doubt that they'll have nitrous support for the ECU, that's just inviting liability fomr street racing related accidents. "If it wern't for the Naaaawz, Little Richard woudl still be here with us today. It's all your fault GM!" The smaller pulley sounds likely though. Still, that's a really small increase in power. Also the romors of the Cobalt/Ion/g5 going with a turbo setup sounds likely so why woudl GM waste money R&Ding another stage? I mean they already have the competition beat. So untill mopar unleashes some sort of stage kit for the .22 SRT4 I really doubt GM even beginning to develop another stage for it.

 

I agree nitrous seems odd coming from GM, but I also feel there have been enough hints dropped here and there for it to be a real possibility. I guess time will tell.

 

You are both incorrect. I posted this response to an email of mine months ago. Here it is again.
PS if you wonder about the senders email validity look at the end of the Ecotec Build book.

Hi, Rod.
The pistons from the 300hp build were from Diamond pistons. We also work a lot with JE pistons. If you are interested in a new piston, I would suggest contacting JE or Diamond and telling them that you want a production-replacement forged aluminum piston that increases your compression ratio to something between 9.7 and 10.0:1.

We are working on an off-road box that will allow you increase your rev limit, run on 110 octane, and/or use a 50shot of nitrous. Please remember that there are a lot of hurdles and concerns for GM to release these types of calibrations. Because of all the issues that large companies are subject to, these types of things are typically done in the after-market.

 

And this GM Dude would be using an AOL E-mail address why?

 

I don't know why they use that address but if you look in the Ecotec build book it is there.

 

so i9f these voids your plan, Y not just go with Intense stg 5?? around 300whp!

 

wow. This is exciting! It'll be interesting to see when it comes out, what kind of numbers it puts down!

 

Thanks max_boost, I guess he didn't read that part.

 

Still, a GM brand nitrous kit sounds very unlikely for liability reasons alone man. GM is a major player afterall and their saftey people would have a **** fit over nitrous being used in the engine. Because as we all know ametures don't use nitrous.

 

i need the big bottles.. 2 of them by tonight!

 

Oh whens the realease date,
How many horsepower with this give me
Will this be under warranty.
let the thread barrage begin

 

I just emailed GM about this to get an ETA. I'll let you guys know what they respond with.

 

As it states this is "an off road box" which means no warranty, at least when using the off road box. There is no warranty for anyone when racing "off road" = at the track.

 

ok i'm gonna ask a smart question here insted of yet anohter F&F quote.

how does the ecu "recognize" spray??

i cant think of any sensor in our engine that i would trust to "recognize" NOS.

 

Actually depending on the ECU type... they can detect it and make a tune for just that depending on what triggers you have set.
Maybe the new piggy back setup has the same features that my ecu setup in my trans am used. I had a F.A.S.T Sequencial system that you could control each individual cylinder along with the nos settings.

Here is some info how they do it....
http://www.fuelairspark.com/Products.../Chapter16.htm

 

I would imagine that it doesn't really dectect it, but the off road box will recalibrate for it. So when your armed, spray would only be tossed in there at a certain rpm and in a certain gear.

As for GM doing nitrous, it will probably be like ford where you have to purchase your own bottle. But to say that major players don't play with nitrous would be wrong.

 

damit daron!!!

make me look like a retard!

i still dont get how it would pick up on when your on or off the spray.

 

Isn’t that what the focus saleens do they come with nitros but if you ever use it your warranty is void.

 

the new e-85 gm cars and trucks use different engine sensors to tell if your using e-85 or not. so im sure they could do it with nos. also i dont think the stage three would come with nos just the calibration for it you would have to buy your own kit but thats just my 2 cents.

 

I don't know about you guys, but I wouldn't run n2o AND a supercharger unless it was a well built motor. Nitrous does some crazy stuff to a motor and adding boost with the nitrous is just asking for something to blow up.

 

OK guys I recieved an email back from GM and this is what it said. My original message is on the bottom. I'm just going to paste it below. Good news is Satge 3 does exist.

Tony-
Can you ask me this question again in another week. GM is shut-down until July 10th.

Stage 3 is not certified for on-road use, like Stage 1 and 2 were (not emissions certified). Also, I need to double check the warranty issue.

Subject: GM stage 3 for Cobalt ss/sc


Hi my name is Tony. I am hear ing a lot about this off-road box GM stage 3 for our Supercharged Cobalts. I currently have GM stage 2. Is this true and if so when can we get an ETA? Thank you so much. I will be purchasing this ASAP!

 

I was told that GM wasnt measuring the diameter quite like the aftermarket does, so it may be smaller than you think. Take that with a grain of salt. We wont know until they actually give us the pulley for comparisons.

As for the nitrous being dangerous. You're right, too much can be. I've been told straight up that a 50 shot is fine, and not to go higher than that with stock internals.

I do believe you get the nicer 2 pass heat exchanger with S3 as well, which many people will like.

 

I'm sure GM measures all of their pulleys the same way so my comparison makes sense.

 

without issue.... i'll beleive that after a few thousand miles.

im not trying to disregard the reliability of this engine. there is just a certain point to which the stock internals can hold up reliably.

 

There are cars that have more than a couple thousand miles on them. The point of the limiter being that high is not to run it up to 7,400 and leave it there, the higher limiter makes it able to shift at 7,000 rpm without hitting the limiter or reaching 7,400.
