What power would come with a cold air, Exaust syst., and a little tune up on the ecotech for a 2.2 LS sedan? 20-30 hp?

 

yes, if by "20-30hp" you mean at the crankshaft, if by "exhaust sytem" you mean everything from header to tailpipe, and if by "tune up" you mean ecu tuning, it's possible.

but if you mean to ask if a cold-air intake, cat-back exhaust, and changing the spark plugs will get you 20-30hp at the wheels, then no, more like 10 if you're lucky.

 

much appreciated

What company parts would you suggest?

 

Full bolt ons + tune (coldair (+5ish)Catback(+7ish)Downpipe(+2-5)Header(7-10)2.4intake mani (+15(apparently)and tune (im hearing the trifecta gives 10-20 alone))

That all right there will give you about 60 horsepower at the most...you might be around 180 if you're on synthetic oil on a cool day. However it would probably be all top-end.

however all of that stuff also would be a fair bit of money

cold air-200
2.4 mani-250? isk
header-400
dp-150-200
cat back-400
tune-275

total 1700$

 

you can't just add up hp #'s like that. i would be surprised if with these mods a 2.2 was over 14x whp. MAYBE 15x no chance it will be anywhere NEAR 180.

 

You dont think so?

Ive seen 15x dynos from guys who just had catback intake and 2.4mani

 

i think he meant 180 at the crank, still id say more like 165.

 

HAHAHAHHAAHAHAHAHAHHAAHAHAHAHAHA!!!!!!!!!!!!!!!!!!

 

Ok, what would I do that would give me the best results?

 

well, it all depends on what your idea of "results" is. what are you looking for from the car? the best thing to do is have some type of goal. do you want to keep it real simple? do you have a certain hp # in mind? do you have a certain track time in mind? there has to be a goal. once you have the goal, then you figure out what you need to do to start getting there. for example, say you buy a header/downpipe. down the road you want a turbo, so now that header is useless. that's just one of many examples. but don't just start putting things on, have something to work towards. THEN figure out what to put on the car.

maybe on some. but majority of 2.2 owners that post up dynos are surprised, and shocked and disapointed by the results. many think they're much higher than they actually are. there's dyno's of guys that are fully bolted that don't hit 140. personally, i think dynos are 100% worthless unless you're tuning, or have some kind of sick ass #'s. but they're way too inconsistant, and don't really prove anything at all.

 

I dont see why you dont agree that will at least be enough for 160... like i said ive seen 150s with no headers or the tune, which im assuming is a big jump, i havent seen a dyno im just basing it on people saying it. i believe someone said their dashhawk or w/e gave it 12 hp on a bone stock cobalt with the tune..

 

see the post above. i doubt people are in the 150's with an intake and catback. they probably just added up the claimed #'s from the maker of the parts they put on.

 

edit: just saw youre post..the 2.4 mani is what seperates the 130-140's from the 150+ i think, but most people are iffy about it becuase of the reported tq loss. BUT, i hear the vinces tune also lets you get the most out of the 2.4 mani.

Lets at least agree if you put those mods on 100 2.2l's at least a couple would be close to 170-180 lol

edit 2: no i saw actual dynos. i believe there was a big thread last year everyone had their mods and their dyno #s in a list

edit 3: could probly dig it up if you give me a bit to search

 

The 2.2 L sedan is at 148 stock...

 

no thats at the crank.

we're talking wheels

 

but that's not to the wheels. the only people that use crank hp#'s are the manufacturers. when people talk about cars and hp, they're talking about whp which is lower due to drivetrain loss. at a 15% drivetrain loss, you're looking at about 125whp.

 

I'm not sure I understand the difference. What would give me a quick acceleration, rear HP?

edit: Thanks for clarifying

 

if you're not familiar with what that is, i would just do a little reading up on it to be more familiar. but the basic concept is that certain things in the car run off the engine, and "steal" some power. things like your alternator, ac, etc. use power from the engine. so the way people measure hp is at the wheels, which is AFTER all the losses. but 99% of the time you hear someone on this site, or other sites or whatever talking about power #'s it's usually wheel hp they're talking about.

 

I understand. What do Turbos enhance? Overall speed or acceleration?

 

both

 

if u get an intake, cat-bak and a one-piece intake mani u could spray a 75 shot, safely

 

to keep it simple, your engine is nothing more than a big air pump. the only ways you're going to get more power is to get more air into the engine, get more air out of the engine, and burn more gasoline more effectively. anything you do to your car to improve performance will do one of these things. a turbo and a supercharger both force air into the engine. more air = the ability to use more gas which = more power.

 

Ok well I didnt find what I was looking for but this is good enough i suppose

Some of the guys are suprisingly low. but the only one on the list that has th 2.4 mani is slightly above 152, with proper tuning, who knows??

another interesting note look at chrisault2004, 135 stock...he could get up there pretty good with some mods i would say. Obviously every car is different, but I dont think N/A 170-180hp with bolt ons is as far fetched as you guys do.

 

bro these guys are full bolted putting down 13x and 14x like i said. a guy with a manifold has 152. that was proving my point that 180 is totally unrealistic. if one car gains an extra 30-40 whp from having the same exact mods listed above, it's just a freak. but thinking that it's realistic is silly, especially after posting the above results. i mean come on, the guy that has 178 is fully bolted plus nitrous!

 

I see you point. obviously there will be a big range, but still theres a few of them in the mid 140s without the mani. going by the fact that the manifold's "claim" is 12-17hp, dont know, apparently trusting the claim puts you at mid to high 150s. Now heres the thing where I think were are disagreeing on. Im basically assuming the tune would be the best power adder of the bunch, except I have no proof. However if youve read the butt dynos people say the car is a whole new beast with that tune. I guess we might have more evidence if we had some numbers with the tune?
