Temperature breaks the bonds of the nitrogen and oxygen molecule...Not pressure.

 

except that everything heats up when it becomes compressed in the chamber

point remains, its no more flammable than oxygen

 

Moving sucks. I just got done yesterday.

You know what else sucks? Having Nitrous but having something wrong with it so it won't engage.

So now I guess we can help settle the it's covered/it's not covered arguement eh? I have to call the dealership this morning and get them to take a look at it.

Will let you guys know what happens.

 

Got it fixed. No issues.

I will be heading to the Dyno this weekend

 

I got it dyno'd yesterday

Stock exhaust, without High Octane mode, pulled 304.7 WHP

Booyaa!!!! I will try to get the dyno sheet available in picture form soon.

Sorry forgot torque numbers...got 283ft/lbs of torque.

I was pushing 17.5 PSI at redline.

This was a 4th gear pull.

 

wow nice numbers man

 

nice numbers I didnt feel like rereading everything what size of shot were you running on the dyno?

edit never mind sig said 50shot lol

 

I had to let my bottle sit in hot water since I don't have a heater to bring it up to correct pressure, but it was worth it

It was also about 60 degrees out yesterday when I got it dyno'd...that helped along with leaving the car sit for a whil letting any heat out.

 

Technically:


Temperature and pressure are a part of the same equation.


The more pressure, the less temperature required.


Also: Nitrous isn't flammable, and neither is Oxygen.

They just facilitate other things' flammability under controlled conditions.

Nitrous also drops the temperature of the surrounding air making it denser.



Sorry, I'm a chemist. Not an organized one.

 

304 whp!!! Holy increased blower efficiency batman!!! Thats awesome!!

Sounds like i may have to go that route once the 60K warranty is up. You are putting out more horsepower than guys who have dumped many thousands of dollars into there engines. So it seems the infamous GM stage 3 PCM is really as good as GM says it is.

I just got one question, how does the PCM recognize the nitrous injection? Is there some wire or sensor? Or does it just detect the nitrous automatically?

 

There is actually a spot for the toggle switch wire and WOT switch wire once they go through the relay... they are redirected straight into the PCM via a connector that plugs straight into the PCM. So the PCM recognizes when the toggle switch is on AND the WOT is at 90% throttle. It then takes care of the rest.

I have ran almost 2 bottles through the car (My spraying has since slowed now that the new toy play period is over) but the car runs awesome...plugs look awesome...no CEL...no issues.

I'm loving it.

FUNNY STORY THOUGH....

I was on my way home when (I think it was stock?? who knows) a yellow SS/SC pulls up to me and my girlfriend on the highway. I was teasing with him...giving him the "go ahead go...go ahead go" hand wave...so he got on it and I floored it while spraying....hahaha

I only stayed on the juice for a couple seconds but once he caught back up he was laughing and just said "Oh my god...what the hell do you have done to that thing!!!!"

hahaha...the look on his face was priceless once he realized I was no where close to stock hahahahahaha....good times.

 

FNFAST STage 3 PCM on the way for me . Did yours come with the harness for pluggininot the nitrous or did that come withthe nitrous kit that you biught seperatly becasue Stage 3 kit on the CED does not show a wiring harness.

 

Bump

 

are you running the stage 3 pulley or a different one?

 

Update just got the PCM hopefully I can install today but it did not come with the wireing harness . It states in the directions that it comes with the GM Stage 3 kit . It is a 2 wire leads with the correct GM pin end crimped on for installation in the wiring harness connector as shown in the wiring diagram...........Help what is the GM part number for this harness .

 

Awesome!

I take it you are going to use it to run a 50 shot or Nitrous as well?

I am running the stage 3 pulley. But the computer does quite a bit for the car. My brother has the 2.79 pulley from CA and stage two and my 2.99 stage three pulley with stage 3 tune is a little bit faster without HO mode or Nitrous.

BC if you need me to I can call my contact at GM and get the part number for you? Let me know man. CONGRATS on the PCM... you are going to LOVE IT!!!

I didnt even think...if you want I can check the P# when I go home tonight off my instructions? or call the guy either way

 

i just wish GM made some more high performance parts. stage 3 is nice but id like to see more out of stage 3 or maybe some more parts from gmpp. the exhaust is ok but anything above 270 hp is bad for the gmpp exhaust cause the pipe diameter is too small. theres no intake for the ss/sc supplied by GM so that bites. the gmpp manifold isnt much of a improvement just being honed out from stock. that about does it for GM aftermarket parts. its unfortunate cause the car should have more power.

sorry im just disappointed with the execution of GM on this car. bugs me a bit

 

Hey congrats man! Dang you got yours before me! Tell me how easy it is to install the pcm and whether or not you have to do a relearn on it?

 

I'm running a stock exhaust on m stage 3 from the headers back...I still dyno'd ver 300whp with HO mode

I say rock on GM!!!!!!!!

 

gratz on the great numbers ma man.
I dare say with those kinda numbers a good exhaust system alone could net you 15whp
header/dp/catback? who knows!

 

FNFAST- please get me the part number from GM for the harness and do you run unleaded 100 octane or leaded becasue I heard 100 leaded is bad and will blow out he o2 sensors. Do you have to disconnect tthe battery when you installed the PCM?

 

Thanks..I meant without HO Mode by the way.

You are going to have to relearn your pcm yes. DO NOT RUN LEADED GAS!!!!! That is BAD!!!!

I will take a look tonight for the numbers and if I don't find them I will call my guy at the dealership.

 

ya but thats the thing i dont like. HO mode is 100 octane right? if so i dont like that idea of better gas more power, its nice and works, but its not conventional to me. preference that u should be able to get high numbers without gimmicks like higher octane gas and nitrous.

the only thing thats worth something is the pulley, injectors, and tune (which is pig rich i hear)

in comparison to the SRT's its power just eats the cobalt. and its not using nitrious or a HO mode. its core power which is more conventional.

is GM stage 3 bad? of course not.
is it worth buying? yes if ur into a little more speed every now and then
are there better stage kits? aftermarket tunes are way more powerful and some offer HPT which allows u to do as u please with ur car tune. hitting high numbers w/o HO mode or Nitrous. intense is a good example with there stage 5 kit
could they do something better? most definetly. when the competition like the SRT group is offering what they have GMPP should be more on top of their game.


EDIT:::: ur w/o HO mode, didnt know when typeing post

 

high octane gas with a tune designed for it is a gimmick?
nitrous is a gimmick?


wow.

 

yes that is without HO mode.

Nitrous is nice for a street car because it is the same ol car you are used to driving and when you need it...it is there.

SRT4's also have HO mode on their stage 2 and 3 kits.

As far as intense goes...I have heard horror stories about their kits...and their stage 5 pulls 276 whp...my stage 3 w/o HO mode pulled 304 or something ( I would have to look again) on stock exhaust...not to mention I am on my 4th bottle and car is same as the day I bought it...perfect without running Nitrous and hasn't thrown one code yet...no problems with the clutch...axles...nothing.

And as I mentioned before...chevy is warranting my stg 3...if intense was so sure of their product...they would insure it as well...but they don't.

I agree. I think both are excellent. And they are out of the norm which makes it have a certain appeal I guess.

But I like the thought of having HO, Nitrous modes...you have 4 ways to run the car...

Stock, HO Mode, Nitrous mode, or HO with Nitrous mode...Says a lot that you have so many options on how YOU want to run your car...not here is this much horse hope you like it. Plus you never really get used to how fast your car is...its fun and different or the same if you want...everytime you get in it.
