Minus the breather that is exactly it (I still want the crankcase pcv hooked to the intake). What size piping did you use? from the TB? does it vary diameter as it goes to the box?

 

yes the throttle body uses something around a 2.5ish, cuz my 3" tube is able to wrap around it, just use a coupler when u put on the intake, it shoudl tighten enought so it wont be a problem...the intake is 3" at the box, so stay 3" all the way

 

alright, thanks bro.

 

yea that set up is almost exactly what i wanna do except i wanna do cold air instead of ram air

 

i thot the coupler i had on right after i bough my car (custom intake) was 2.75" but that was almost 3 years ago so i could be mistaken

 

i have a question how do the cobalts make 127 horsepower when GM advertised them to make 148?

 

whered the hell u get 127??? ive seen stock cobaltsmake between 112-120@wheels stock, i made 127.5wph, and 139wtrq modded...im looking at making more than that next time, as i have gotten a new header, new catback, new trq damper now, and i will have the dp from exhaust depot so im hoping to get a good 135 whp

 

ok so why does chevy advirtise them at 148 horspower and 155ft/lbs of torque???

 

thats at the crank

 

how do you remove the plastic engine cover. Whenever i turn the cap it won't move. Anyone know of a thread explaining it? Do i just twist that oil cap and yank it off?

 

well not yank, but give it a decient pull, it's not on there by much.

 

the cover has 2 tab like things that hold it, one in the upper left corner, and the other in the bottom right corner, the valve cover has a stem that foes into the cover to hold it but pull from the upper left and that shoudl come off, than pull from the bottom right and the same should happend..real easy, oh and take the oil cap completly off, dont just twist it, twist it and take it off

ps-148, 152 is what gm rated the 07+cobalt at the crank, 05-06 got rated 145, 155

 

oh so which is the correct real horse power we're putting down, and what would bw the horsepower gain after i put a AEM cold air intake DC sports headers, and a DC sports cat-back exhaust???

 

the 112 to the wheels is about right. crank hp doesnt really matter in all honesty. with those mods you will maybe be at 130 if your lucky. i see you already have the k&n sri...you wont see that much more of a gain with the aem cai, maybe 1 or 2 hp at most.

 

damn ok that sucks, what if i did a custom intake with a 3" inch diameter
