Air box question?
 

I am thinking of putting in a drop in K&N air filter instead of a CAI. A day ago I swiss cheesed the top of air box. Is that going to do anything or not?

you ask after you did it? lol

I wouldnt leave it with the stock filter in there.
stocker is just paper....water + paperfilter is not great.

is there sufficient drainage in case you let water in the top? dont want to make it a swimming pool for your filter...

haha... just get a CAI or SRI

that will most likely LOSE you performance, because the air is no longer streamlined. imagine you're blowing through a straw. now, cut a few holes in the straw and see how hard you can blow. you're blowing just as hard, but the air is much more spread out, and doesn't flow anywhere near as quickly. get a new airbox ASAP

When you say top do you mean on the lid part where the tube connects to the throttle body is connected?If it is the lid you put holes in the air filter is being bypassed and dirt will get in your engine.If you mean the top half of the bottom I think it would be ok probably be a bit louder .How big are the holes? I wouldn't waste money on a cold air intake. I have the air box mod on my sc except I cut the whole side out of the air box.I see under .5 lbs scip on the aeroforce sometimes at max rpm.though.

you will not get to 215 without spending money. also, spark plugs and wires will NOT give you 8-12 hp. i would say more like 2 or 3, tops. the cobalt does NOT weigh 2600, it's more like 2900.

how do you know you have 151 hp?

dude you made holes after the air filter. if they are on the top, like you said, then you are letting unfiltered air into your engine. that means large dirt particals, leaves, what ever can get in there now will. you need a new air box soon.

with the sports package your governor is set to around 120. with no mods, i would say the 2.2 is drag limited to much lower than 142, unless your speedo is just way off. there's no way a stock 2.2 is getting to 142. the ss/sc takes a while to get to 142, and has about 100 more whp stock.

not really. just a muffler is maybe good for 2 hp. won't feel a difference. this has just been posted in another thread as well.,

what are you talking about?

video or bs. i would go so far as to say it's definitely not possible. unless they somehow accidentally put the wrong engine in the car.

hmmmmm
maybe on a really big downhill....with a Z06 pushing you.....

Dude

I am dead serious, I will try to get a video or a shot. I will keep in touch. I Have to Blaze!!!!

Thanks Again

Those holes in the in the airbox must have done wonders..... i bet you have those performance stickers on your car too those are good for 15 hp

actually, anybody that knows wouldn't try that.

yea man, that airbox idea was terrible... i wouldn't be surpised if you blow your engine soon...

i'm 25. how old are you? :lol:

i'm not the one that comes onto an internet forum and starts lying about my car that probably puts down less than stock power and makes rediculous claims... it's certainly entertaining though

hahaha anomalous you have the funnyiest comments, id give you more feed back but i cant yet ;)

Did anyone else notice this

The other thing that is weird is that some guys I have talked to said that the newer Cobalts have a governer and that the top end is 115 mph. Mine does not have a governer, My step son can back me up on this I have gone 142 mph in this Cobalt and still was climbing. The only thing I saw that the revlimiter would kick in when in park at 4000 rpm. Any explainations?????

Take a look at his gallery it says 121 is max speed. But the funny thing is i almost believed him cause i have hit 130 in my 2.4 ss and i had room to goo, but mine is also manual. with an auto there is no way lol. nice try son, again i have said this before, there are 10,000+ members on this site, what is the point of lying atleast 1 person if not 100s know what they are talking about lol, you will get called out eventually :lol: nice try man

lol and also i have the 2.4 ss not the 2.2 ls lol

if you car can hit that, would you want to race for pink slips ;), i would love to race for 1,000

lol this thread is rediculous.. This guy is obviously a lil :nuts:

lol next thing ur going to say is when you took the pastic off it said its the 6.0 GTO engine lol. i guess you were blessed and the company "accidently made your car fast " lol, but if ur car is as fast as you say it is, and you got that sick air box mod. lol you having a 2.2 and me having a 2.4 i wouldnt stand a chance :) like i said, 1,000 lets go pal, there are plenty roads around here that you can hit 150+ in your car ;) :lol:

Listen

I am not BSing I really hit 140mph, I have nothing to gain and I am not trying to win a popularity contest, I was trying to figure out why my car did that not start a bitch fest.

Any way!!! I have to BLAZE, so take care. chat later.

I would find a stock airbox lid before taking your car in for warranty work, and before you find a new lid I would tape over the holes before you do permanent damage to the engine. The engine bay gets really dusty on these cars.

this thread = good for a laugh. A 2.2 Cobalt with an CAI, header, exhaust and a 50 squeeze of nitrous barely made it to 135 (and anyone that says I have a speed limiter...Yes I do..However it doesnt work when the VSS wire is cut). GPS says 135 and its usually within 2-3 MPH of the stock speedo..

Theres no way a stock cobalt automatic is going faster then that.

yea all i know is in my 2.4 i got to 130 it took a while from like 120-130 i mean i had plenty of gas left. (in a stick is the car limited to what?) im thinking i could prolly hit 140-145 BUT im sure shit would start to burn up haha. but i can deff hit 125-130 pretty easily.

Today I went and ran my car hard and wanted to see if the custom filter cover would hinder the car in any way and it ran very well. No dust in the filter. engine tep was just a couple of degrees less then normal.

I will see how it runs later this week.
