aveo boosting

[Denis]

sorry i guess i missunderstood you, but any way that prebent part will cast same or more than the amount of steel need to make the hole kit. its not going to be all one pipe it will be in 2 parts (can be use as a short ram) and the bend will not be 90 degrees, from the throttle to the hole in the fender the pipe will go on a 20 degree slant, and the other peice of the pipe will be bend made to 70 degrees. the 2 pipes will be conected with a plastic conector.

i tried one of those plastic connectors if u wanna do it right i suggest silicon tube...the u can just make a hole to put the air sensor in....i dunno if the angle is really gonna make a difference on the 1.6l

hey where's the option on the poll for both lol what if I wanted a supercharged and turbocharged aveo I'll admit that idea is really crazy but I'd get a kick out of it if someone actually acomplished it

[Blade979]

Someone did that to a first gen MR2, they supercharged the turbo....no lag.

[exodus]

why not just go twin turbine if you wanted a low lag turbo setup...

...and if you want to get technical... they turbocharged the supercharger... the first gen mr2 never came with a turbocharger stock. They came N/A or S/Ced.

Now on to the pros and cons of each setup as I understand them

Supercharging gives you predictable boost with moderate power gains (With one kit you can get a focus zx3 from 130hp to over 200 for under $4k... can't recall the brand, though... something with an H?). Your powerband won't have any real sharp spikes or drops, though I believe the torque drops off signifigantly at high rpms, which means you'll want to be shifting out of first at 4.5-5k rpms, rather than hitting redline (anyone who's driven a SOHC engine should already be used to this). You can generally use low boost superchargers without the need to remap the ECU. The downside to all of this is its high RPM and high speed performance. At anything beyond regular highway speeds you won't really find it useful. Superchargers are usually best in low to mid speed circuits/stages where long stretches aren't very abundant, as the advantages are primarily in corner exits.

Turbocharging has near limitless high end power. The downside to this is "lag". Since the turbine is driven off the exhaust gasses, at low rpms there won't be enough to drive the compressor fast enough to attain full boost. Coming on and off the accelerator a lot will also add to this, making it difficult to predict when the power will kick in. There are ways around this, using a twin turbine setup. One turbine has a smaller diameter than the other, allowing it to spool up faster while the other is of a larger diameter, allowing more boost once it has spooled up. Your powerband will rise sharply until around 4k rpms where it mellows out as the RPMS climb, and power shouldn't drop off until well beyond redline.

There are also downsides to forced induction all together. With either setup there's a phenomenon which I can't recall the name of at the moment... Randomly if you go from wide open throttle closed very quickly they ECU gets confused and either dumps a whole bunch of fuel into the cylinder or starves it, thus stalling the engine.

fun!

ok lets think about this reasonably.... you can make headers to put a variety of turbos on but you cant just put a supercharge from another engine onto yours(wont work)...you could use a centrifical supercharge but it also is gonna need its own oil supply like a turbo....a turbo will give you more power than a supercharger which seems to be what you want....get a smaller turbo if you wanna reduce turbo lag and if turbo lag is such a problem why do most people turbo a car rather than supercharge...a turbo would be easier to install since there is plenty of room for it...also you cant boost this engine and expect it to be as nonproblematic as before...that is why you need to know what your doing when you turbo a car or supercharge it cause one wrong mistake and your engine is shot(personal experience)...so with either method there comes the responsibilty that something could go wrong....so if you want a good daily driver stay away from boosting( just for the aveo/swift/wave since they arent boost from the factory like a eclipse gst or anyother factory boosted car) do want you want im just telling you that a turbo is reasonably the better choice

We all just need to get diesels.

Diesel turbo w/ knock and EGT sensor: "Oh, it's knocking, need to turn down boost, no probalo"

Gas turbo: "Oh it's knocking, need to get valves and maybe pistons"

This is how i see it: Superchargers go on v6 and v8's. turbos go on 4's and 6's. Reason:Superchargers give bottom end power and a 4 banger does not need that much bottom end.

The pros:
Supercharger, effective, and more HP gain.
Turbos, more efficient and no drag on the engine.

Cons:
Supercharger, adds drag cause your adding another belt for the engine to turn.
Turbo, turbo lag but they have improved this sooooo much in the last decade. the lag is usually only about .5-1.5 seconds when 10 years ago you had a lag of 3-5 seconds.

If a supercharger was better don't you think that they would have used it on the STI, EVO 9, 3000 GT, Jetta, Golf, The new (2007)Solstice, MR2, Supra, SRT4, Cooper S, even the NSX...and more. and why don't the turbocharge the (retired)Camaro, Corvette, Mustang Cobra, or Viper (but there is aftermarket for the viper). Why do you think Car designers do it this way....efficientcy, effectiveness, and cost effective.

[AveoSam]

yea like aveoike said why would they put them on all those cars. i agree turbos belong on 4bangers and v6s while superchargers belong on v6s and v8s...so ours is a 4banger so it deserves a turbo....just one note thou, i thought turbos created more hp overall compared to a supercharger? also isnt the cobolt ss supercharged? and i do agree they have changed the turbo so that turbo lag is the thing of the past ;D

[aveoike]

I edited that Cobalt error....dont know what the heck I was thinking. Yea that is one car that is a 4 banger with a supercharger. Thanx for pointing it out. So denis if you can see, there is a method to the madness, and that you can see a trend.

Someone correct me if im wrong but, dont you gain aproximatly 25% HP increase from a turbo and up to a 40% HP increase from a supercharger?

[AveoSam]

i thinking its the other way around...what about parasitic lost due to the belts....and u can run higher boost with a turbo
atleast that is what this site said

What is really comes down to is EFFICIENCY. Superchargers take power right off the motor to turn them; power that could be going to your wheels. When you have a motor with little power to start with, a supercharger just isn't a good choice. As aveoike said, turbo's present very little load on the motor, and the power out to power in ratio is a lot higher.

[Bikoholic]

Supercharger all the way. Though it depends on what your gonna use the car for.

turbo that s2000..... ;D

No way the thing has no bottom end as it is.
