Ok so my tech had dyno'd his car, he hit 245whp. when he had tuned my car he was so suprised. he drove mine and we drove his and my car is way faster than his.. he had estamated my car at about 270-275whp.. im happy happy happy

 

I am gonna say about 245whp
And after a run or 2, it will drop to 235ish from heat soak unless you have some cooling mods I'm not seeing.

 

Generous dyno...I had the exact same mods on mine and put down 236. Either way, as long as you like it.

 

yea actually i get my duel pass and heat exchanger tomarrow and i ordered a chiller

 

Should of got meth injection. Best cooling mod out there right now. IMO, it is the best bang for the buck there is.

 

screw meth, i mean maybe later but for right now i dont want to blow nething up.

 

That's why you get it.

 

i know but that will give too much hp. im likely to blow a piston

 

Uhh...no. If you keep the same set up you have now, meth will only make things safer. You're not going to blow a piston on a properly set up 2.8".

But hey, to each their own. In the end, it's all in the tuning.

 

yea but ive seen vids with people that had a little over 300hp and were blowing pistons. our pistons are really weak its just not worth risking

 

hey what kind of cai would you guys recommend?

 

xtc intake. form www.cobalt-addiction.com i love it

 

K&N or Injen.... xtc is junk!

And you aren't anywhere close to 270whp... it takes more than that to hit 270!

And meth has ABSOLUTELY nothing to do with making hp (that is the tunes job), it adds some octane points, and cools of the incomming airflow!



back to what you were doing

 

wow, you can read books.. i know you have to tune for meth but even know you dont tune for meth you can still gain hp. just nowhere near with a tune. and second off the xtc intake is really good and im pretty sure u have never had it on your car, but you know its junk.. lol what a joke. neways you can listen to just m-dub or do some reaserch. im just saying that my tech put down 245whp and my car will beat the **** out of it.. you can pm him and ask. his name is BLILBT ( real name bill ).

 

NO ONE LISTEN TO ME.... eh whatever buddy!



have fun

 

i dont know man. im just saying i should be up there. there has been stock cobalts that dyno'd at 223whp.... STOCK i repeat STOCK

 

I know... I have one of those "freaks" too... but since I don't know what I am talking about... continue on!

 

meth is a cooling mod+ hp if you run hot from having a small pully it wont hurt you getting meth it will only help

 

the ss/sc's yes it was under-rated...everyone knew that...the LNF has not been underrated it is very close to the true crank hp which means you are in the 240whp range where most of the ss/tc's have dynoed at except yours and one other loonies.

 

ok so what would you guys recommend for an exhaust?! im liking the megan, hahn, and the borla but thats just off of how they sound...

 

i don't personally like the megan...many do...i love both the hahn and borla...wither of those 2 is a great choice IMO...whatevers cheapest

 

the only freaky thing is that dyno your running on...


i made 256whp on a 1000hp chassis dyno... with 3.0 pulley, full bolt ons, port and polish blower, and custom meth tune... so i must have a dud huh...

 

yea dude i was leaning more towards the hahn and the borla... i just wish the borla had 3" piping like the hahn

 

That's that typical opinion of someone who doesn't understand the way something works. Please don't confuse Meth with N2O. While they both achieve the same goals, they don't really do it in the same manner. Meth will never do anything but help your car as long as it is installed and tuned properly. It basically acts as a liquid intercooler to help control the heat from the blower, therefore allowing you to run more timing and in turn, make more power. The people that have been blowing pistons have simply "over tuned" their cars to a point where something just let go inside.

 

I seriously doubt any stock blowered cobalt would see anywhere around 30HP off meth without some serious tuning and dependency on a steady supply of meth.

If you were to get meth inj., it would help to make sure you keep that "270whp" you speak of the whole time youre driving, instead of the heat soak killing the IAT2s...
