Ok, all went well at Haddad earlier today. I'll add the link from youtube to this post on Monday. I'll also add the Dyno Chart printout I have. Well, Here are the numbers:

On Stage 3 + 100 octane mode + 50 Shot:
Max HP: 274.8 @ 6864 rpm
Max Tq: 306.8 @ 4469 rpm
AFR: 12.459:1

On Stage 3 only:
Max HP: 217.9 @ 7000 rpm
Max Tq: 181.6 @ 5481 rpm
AFR: 11.227:1

Here is the link for the Video:

2005 Cobalt SS SC GMPP Stage 3 on the Dyno - YouTube

 

thoughs are some pretty weak ass stage 2 numbers...ur tq numbers going from stage 2 to the stage 3 really confuse me though...didn't think stage 3 even with 100 octane could do 300 tq

 

i'm assuming this was when you were spraying. The torque numbers are insane.

 

Wawawawawa WHAT......

 

Yes on Spray. I added that in. Thanks

 

there is something wrong with those stage 2 numbers.

 

considering the car being stand alone with hardly any mods other than the stage 2 bolted on and his alttitude makes crediable numbers.

 

what cooling mods do you have while running stage 3?

 

what is his attitude?

 

Wow.

 

it's like somewhere between 330 feet and 500ft depending where he lives. You must take into consideration humidity, temp etc. The dyno may also be a little too conservative. I'm sure it wasn't a dyno jet.

 

the tq numbers are becuase its a dry shot

 

thats what i was thinking 306....DryShot...

 

sick ass stage 3 number's with that dry shot.. and you mean to tell me you get traction in first with those DR's i sold ya? just WOW... but your AFR in plain stage 2 need's alittle tinkering man 11 isnt that great. which is why i think the number are alittle low..

 

no CAI?

 

LOL it will break em loose if not warmed up!!

Check out the video, it's finally up!!

No, just a k&N filter

Stock downpipe, Honed manifold, gmpp 2.25" catback, period

 

Where did the stage 2 come from? Did you dyno Stage 3 without the nitrous?

 

wheeeeeeeeelllllllllllll


ok then

 

Hes got more powa than you!

Question is.. will a 2.7 pullied pushin 280hp last longer than a 3"er with a 50 shot... time will only tell...

 

yep. because i know what to do.

he has more torque. not hp



we're not done yet kiddies

12.4 afr on bottle fun is asking for it

 

Agreed. Dry kits scare me

 

I take that back, you are right. I forgot you were over 280hp. What is going to kill his motor at that AFR? EGT too high being that lean? Does N2O help EGT's or just make them higher?

 

the afr on juice is kinda scary really. it won't actually kill it, it's the unknown area of egt's and other lil things here and there.

i honestly thought it would do more than that on bottle. this is the first time i have seen true numbers for a full gmpp car. i wouldn't say it's bad actually.

 

Yes. No Nitrous, No 100 Octane Mode on. Without the 100 Octane mode on, it's pretty much useless.

 

What kind of dyno was this? Your numbers appear to be Mustang Dyno like numbers. I will say damn nice torque number you have there, and it's definitely where you need it. Horsepower sells and torque moves! Otherwise, it is a bit too lean for my liking.
