Do u know what a Turbo Charger is? (ill assume u dont and explain anyways lol) a turbo charger in simple terms is a way to boost horse power out of your car. What it does is it Forces more O2 into your engine wich allows you to put in more fuel as well wich in turn makes the engine burn hotter and faster giving u a good HP boost, when someone says a "M3 Turbo" they are reffering to an M3 that some one put a turbo on to boost the HP.

I ain't no turbo expert but imagine this, when you start a burning grill, fanning it makes the fire larger. Turbo chargers use wasted exhaust gas and forces it back to the engine for a bigger burn, resulting in more energy = power. The problem is that the wasted exhaust has to me made first and then it gets compressed and forced back into the engine. This takes time. So, when you slam the gas you won't feel the acceleration right away. This delayed reaction is the drawback. The car is not responsive. You can minimize this by having multiple turbo chargers in different sizes. This is why BMW, F1 cars, etc only uses naturally aspirated engines. It's more responsive, lighter and uses few components that can go wrong.

You will soon want to know about super chargers. They're called parasites and they use the engine's drive train to produce pressurized air and then force it into the engine. So, you get the power sooner, but it drains the engines naturally ability to produce power. But, it makes up for the loss in power, plus adds more by pressuring additional air into the engine. A turbo will lose power by restricting the exhaust from fully and freely escaping, but it's not much.

Supposedly, a turbo charger gives you more power but has a delayed response time. A super charger has better response, but less power.

Well, I once didn't know about turbo or super charger. Everybody goes through that stage. So, everyone who knows about a turbo must have asked in order to know.

supercharger pushes air into the engine, and is powered by belt. Supercharger does not suffer lag, and it provides quicker power. Turbo, on the other hand, pushes out your exhaust gasses faster

Well i knew i would get some responses like that. Didn't really care. Anyway, i think i worded my question wrong. I know how "superchargers" work in general... I was just wondering if there were common ones put on M3's or even if there were m3's with stock turbos...

reason I ask: I posted a topic (on another forum) about a whistling/squealing noise that my car makes when your push the gas while driving (only while driving, not in park) and it only occurs when you give it a certain amount of gas, like if you push it down any more, it stops whistling...
someone on there joked and suggested i had a turbo and didnt know it.


And BTW, congratulations to all you smarty-pants' out there.

There are no M3's that came stock with turbos. and i highly doubt you have a turbo on your car and didnt know it. whoever u bought the car from would b ramming the fact that it had a turbo down your throat the second u spoke to them lol. hope that is more helpful .

You're driving a turbo with a blow-off valve? It makes that whistle on occasions exactly as you described. It's supposed to be a sound of preference for some people. Personally, I want a quiet car.

Sorry to be a snitch, but the accurate way of describing how a turbo works is that the exhaust fumes are used to SPOOL the turbo that forces air from the intake into the engine. The exhaust fumes themselves are not burned. Blow-off valves allow a turbo to release these fumes quicker so that the next flow of exhaust fumes can re-spool the turbo.

Intercoolers cool air that is sucked in by the intake (consequently through the turbo) because cold air = denser air. Denser air means more O2 per pound.

EH? are you asking a question? Like i said, i doubt that i would have bought a car with a turbo and they forgot to tell me... Sounds more like a squeaky alternator but that would rule out it not whistling when in park....

Which brings me back to my original question, how do you tell if you have a turbocharger? Jeez. ghead
