Lets Play The Horesepower Game!
 

Alrighty boys and gals, lets estimate what my whp will be at with these mods i plan to get in the near future!

Current Mods:
KN SRI Intake
Resonator gutted

Mods Soon:
ZZP 2.5 Header/Downpipe Combo Catless
Exhaust Componests Delete/Swap (Flomaster Muffler, 2.25 section-2.5 section swap, perhaps Resonator straight piped with 2.5 piping)
Custom EFI Live Tune

Perhaps:
Nitrious
Cams/Rockers

So play the horsepower game for my Mods soon and if you feel like it play it for the Perhaps also lol

btw im a 07 2.4 5 speed!
thanks guys and gals!

idk i would guess.. but i'm sure i'd be wrong

toss some numbers at me!

id like to say with the full bolt ons (soon mods) around 180

with the Perhaps exluding n20 of course..id say whp of around...200-210..

2whp, :)

nice thats double my whp right now

I thought these cars were cam over bucket, not rockers....

i heard jbp where making a set of rockers for our cars..thats all im basing it off of to be honest

no idea.

nice list of mods tho. are you at the LC on sunday nights in the summer? i think i've seen you around.

the Liquir Commision?? lol...

dam such a big gain, haha jk

biggest gain in cobalt history

come on guys i need some serious numbers haha

yeah the liquor commish. haha its pretty busy there on the sunday night cruise.

back to topic tho, what kinda power does the 2.4 put down stock anyways?

173 crank stock...i got a intake so i figurei m around..170 whp but that will change very soon :D

i have seen a couple stock dino's for the 2.4's and they are all around 155hp to the wheels. so with your intake u might be 160-165. with ZZP 2.5 Header/Downpipe Combo Catless
Exhaust Componests Delete/Swap (Flomaster Muffler, 2.25 section-2.5 section swap, perhaps Resonator straight piped with 2.5 piping)
Custom EFI Live Tune
180 would be a good guess depending on how much the tune gets ya.

When I get my tuned (hopefully soon, moving into a new house is messing the money situation up though....) I'll let you know. Your whp number should be very similar to mine after you do all your exhaust work. Here's my setup for reference:

AEM CAI
CA v1 header
XTC 2.5" de-cat downpipe
ARK N2 cat-back
Ingalls ETD (not sure if that'll really benefit me on the dyno in terms of putting the power down)

I'm probally gonna the Vector tune for reliability and low downtime reasons, as my car is my daily driver. Gonna keep the stock injectors even. Shooting for 190whp and ill be happy. Gotta get my car running 100% first and take car of my CEL (11 codes at the moment, mostly from a clogged fuel filter and no cat). Then she'll be ready for the tune and a dyno session. :)

I was going to say with the mods listed including what you have already, minus the nitrous, you'd be looking at around 175 whp. An intake alone will not get you almost 20 whp. A stock 5 speed 2.4L usually dynos around 150 whp.

yeah let me know! i hope you dyno goes well!!

Stock is about 145-150 whp

I have a CAI and a cat-back and I dyno'd 167 whp

Doubt with just an SRI you have more HP than moi.


Now with all those mods you wanna do, about 190-200

But man you are talking some $$$$ with the cams and all that...I have a DP and header to put on then I will slap her on the dyno again and I'll let you know.

i have no clue lol i'd say mid 180's with all the bolt on's minus the cams

hmms..

I'd say 210-220s spraying... N/A around 180-190whp!

those are some good numbers spraying..very tempting..

I say no to spray. Too risky for me. My car is my ONLY car and my rents live two states away, so if something were to happen to my motor, I'd be SOL.

Oh yeah Projekt, what happened with getting a more "mature" car? Thought you wanted to ditch the SS and get a Z or something.

i was going to, but financly it is not the smartest thing to do right now..and im on a lease..so ill drive my car till the lease expires, around that time i should be done business school and be able to get my mature car, but for now im modding my cobalt :D
