just got the stage 2, gm headers, and the k&n intake, and was just wondering what a good estimate would be on the new hp?

 

250.

 

estimating hp is totally rice... put it on a dyno

 

well the stage 2 alone was supposed to ad around 40hp

 

caring about hp isnt too great either...go to the track. see if you know how to use hp.

 

240Whp + for sure.

 

estimating a dyno is no more pointless than dynoing a car if you arent tuning it.

camp- thank you, ive been saying that all along

 

ok... well i do care about hp considering i paid for it, and i do know how to use it, there are just no dyno shops around here. and im new to the ss.

 

^^^ oh dude dont get us wrong, we care just as much about horsepower, and congrats and good luck on the new mods. just remember you get respect when you win races not when you hit a number on a computer screen

 

ok no need to flame guys, its no different than when someone comes on here saying they found a new supercharger for our cars... all everyone ever says is "how much hp?" "how much money?" "is it a direct bolt on?" same thing, if hes curious about the numbers just let him know and move on.
not trying to be an ass but every thread that can be so basic just turnes out to be a soap opera.

 

HP is tough to guesstimate, but I'd say the previous estimate of around 240-250 would be most accurate.

Just as a side note 1) the car only has one header (I hate when people say headers) and 2) GM doesn't make a header, they (actually ExtrudeHone) sells a ported stock exhaust manifold, it's not a header and probably won't net you much at all in the way of gains.

 

I'm getting stage 2 installed on 11/24, have an intake, and will dyno mine with the current intake before and after the install. I'll post up some charts and you can add roughly 4-5 hp to it cuz of the header, that'll be pretty damn close. I'm sure if you searched it on here you could find some posts pretty close to the mods you will be getting. My estimate will be 40-50 whp from stock.

 

I'd estimate 240ish hp and 220 torque
