Supercharger for our 3?

[baymoe]

Anyone have inside news at Eaton or other makers of superchargers whether they're going to create one for our Mazda3? I want one for my 3!

[WhiteSpeed3]

we were talking about this for a bit last night with some of the focus guys

i personally think there supercharger will fit the 3 due to having the same 2.0L and the 2.3L engines but i dont think anyone has tried yet

Superchargers are quickly becoming a thing of the past. GM had to switch to turbos on a lot of their supercharged cars because of tougher emission standards. Hmm.. I'm a little off topic I guess.

[Wild Weasel]

How are emissions affected differently for a supercharger than they are for a turbo? There are advantages and disadvantages to each. This is the first I've heard that they're becoming a thing of the past.

I know there was extensive talk about Focus Supercharger kits on the Mazda3, and without a ton of work, they would not fit. I cant remember the exact reason it wouldnt though....

I would still rather a turbo over a SC

turbo FTW!!!!

I'd RATHER have a trubo of course... but superchargers are usually significantly cheaper by comparison.

Scarbro, why would you say a supercharged engine is harder to pass emission standards over a turbo on the same engine? Just curious because I had a turbo on my last car, but no personal experience with superchargers, but I can't see why that would be the case at all. They are pretty reliable units, more so than turbochargers in my opinion.

Also, since the focus has the same engine, I am sure its just a fitment issue. I don't know why they would NOT make it for the mazda3 that being the case. I am sure they could reuse alot of the same parts in the focus 'kit' for the 3. Oh well.. every time I investigate a turbo kit for my 3, I always come to the conclusion that if I am going to spend t hat kind of money on a car I'd rather sell the 3 and get a completely differant car all together in a higher price bracket.

I read it in the Star a while back. The Cobalt SS supercharged was scrapped because of emissions. A turbo replacement is supposed to be better on emissions. I don't know. It doesn't make a lot of sense to me either. I guess I am going by memory on this one!

[mogul_pro]

Maybe because its not the same engine either? (I dono..)

But the new SS is pretty powerfull and light... brembos come standard too.. pretty sweet... i wouldnt want one but i can understand why people would... speeding tickets come standard too lol.

Reason for asking was because of the ease of installation and Plug and Play nature (most of them anyhow) of superchargers. For someone like myself who haven't touched FI, and would like to get into it, want to start off with superchargers for that fact.

The linear power delivery is a plus also

[Wild Weasel]

Superchargers aren't really any more "plug and play" than a turbo is. Both need the same sort of fuel delivery and sensor upgrades to make them work.

I thought they went with the turbo on the new Cobalt just because it was more powerful and it made more sense to use the turbo version across the board than to keep it on some cars like the Solstice and HHR while keeping the blower on the Cobalt.

A supercharger is generally a safer system, and tends to be more seamlessly drivable for the average person.

[mogul_pro]

Yea I wouldn't really say that superchargers are a thing fo the past... the new z06 will have a supercharger... And instant boost.... no lag is good lag!

+1. There is nothing more plug and play about it.

A blower has better linear power, but a turbo has potential for more power, and with very very little effort (can be a good point, or bad lol)

I wanted to post that .gif you made of little Weasel installing the charger on the Sunfire but I can't find it. LOL

[Kevin@nextmod]

I guess the cobalt went with turbo probably because of power and fuel economy. I guess as long as you stay under the range, the turbo won't kick in and you save gas. The super charger kicks in at low rpm causing the thirsty engine.

[Wild Weasel]

A supercharger, when not under boost, takes almost no power to turn, so there's no loss of economy there. It only kicks in when needed (heavier throttle), otherwise it spins freely.

Oh.....now that i don't know, i have no experience with either so i was just guesssing.

[Wild Weasel]

There's a bypass on the blower that opens up under vacuum so until the throttle opens up enough to reduce the vacuum enough to close that valve, the blower is free-spinning and needs less than 1 hp. It's basically a fancy idler pulley with some spinning bits attached to it.

Didn't know that. Cool.

Not only has The Cobalt SS dropped the supercharger, Mini Cooper S has dropped the supercharged engine for a turbo also.

[midnightfxgt]

Easy explaination... Turbo > SC JK JK!

[WhiteSpeed3]

will i work at a GM dealership and im gonna look into this thing about why they switch and will update u guys but im pretty sure this thread is a serious case of thread jacking

[1flycdnM3]

I am with Vince on this one and I think everything that has needed to be said has been "re-hashed" to death now

only thing to really know that is important is this:

Turbocharger > Supercharger

*lol*

[Mijunk]

My understanding is GM switched for 2 reasons. One being that the contract with Eaton was up, and two they had the turbo from the Solstice with more power. The turbo motor has better emissions because of direct injection.
