Eletronic Turbo for a new BMW

[marcostognozzi]

If someone can answer this...someone who has already done that´or knows anything about mechanical stuff of these german cars


This message is about the new 5 series "545 4.4 V8" or the new 3 series "Motorsport 330 V6". Nice cars in my opinion...but

Can we install an Eletronic Turbo on Both Cars?
Is it possible to set this Turbo boost to start "at 3750 RPM over++"?

bmw's are not V6's, but inline 6's.

An electronic supercharger, maybe. Not a turbo, a turbo is a supercharger driven by exhaust gasses.

You'd have to move some serious air to be effective, IMO not practical.

To achieve the same CFM of air that a normal turbo or supercharger does, it takes a lot of power. On a 12 volt system, somebody figured it out to be 1,000 Amps.
Basically, they are a joke and simply restrict your intake.

Oh, sorry... I typed the wrong thing my intention was to say that 330 has 6 cylinders
.

By the way, what does "IMO" stands for? What means this short name?

And I still didn´t understand.... You say that these Turbocompressor kits that pushes air and Gas mix into the cylinder won´t be effective on these cars?

If you are talking about the 12 volt electronic air compressor that you hook up to your intake, then no it won't be effective. As an example, (taken from the thread below) an 03 svt cobra supercharger takes 60 hp to make 10 psi. The compressed air gives the engine more power, but it still takes 60 hp to compress the air. There is no way this 12 volt fan is 60 hp, or even 30 for that manner.

60 horsepower is 44,742 watts, which is 3728.5 amps at 12 volts. I don't know what the amp rating is on BMW alternators, but a dodge diesel 3500 pickup (big ass truck) only has a 160 amp alternator.

Basically, these kits blow air into your intake, but they blow less air into your intake than your car normally uses, so you end up restricting your intake and losing power.

IMO=in my opinion

The turbo kits for M3´s and M5 are witch type, the eletric or what?

no they're driven off exhaust right? I've never heard of an electric turbo.

ELECTRIC superchargers DO NOT WORK. They are a scam and a ripoff please do not buy one.

No no no no no.

The "kits" for any car that "work" are either belt driven supercharger or turbocharger (exhaust driven)...

[twisted69]

There is no supercharger/turbo thats electrical. You eather have one driven by exhaust gass (a.k.a. turbo) or of a belt (a.k.a. supercharger) If you happened to buy one already, sorry, you waisted your money. If you are looking into them, you would be better off taking the intake hose and blowing air into it with your mouth. There one of the largest scams out there. Dont fall for it.

Okay Okay Okay, Once again I mistyped it´s not ELETRICAl it´s ELETRONIC TURBO.

The first thing I want to know if it´s possible to install a turbo on a new BMW like 545 or 330 and set it to work only after 3500 RPM
I have seen some cars that are equipped with a Turbo and when you step softly until 3400 RPM the Turbo doesn´t push hard the car(saving Gas) but if you step over 3500 the turbo works and pushes the car hardly giving it sometimes extra 40 horsepower

My intention is to do that, but as far as I know, German cars are no so simple, I think I have to set the "ECU" for the new stuff I´m going to install.... RIGHT?

[nondescript]

I _think_ you are talking about the turbo spool... I don't think there is any electronic govenor (or bypass) involved in any factory turbo setups. You might just be able to use a larger turbo than your application calls for if you "want" that delay. However, that isn't normally suggested. The better way to save gas with a turbo car is to use self control with the go fast pedal. :P

Oh, and also - yes any changes that you plan to make will require new code on the ECU... When you change something the entire system needs to understand what is happening to it. You'll probably want larger injectors too. No good having more air if you don't have more gas to keep the mix right.

[twisted69]

Turbos are always working. There just not making the good hp boost until higher rpms. If your wanted a system that kicks in after 3500 but want to save gas then really your only option is nitrous. I know some people dont like this idea but you only really want like 50hp and dont want it on all the time then i think this would be your best bet. If you get the right system then there is no need to have the ECU messed with. Venom makes a really good and really safe one if your interested in there. you can have it WOT (wide open throtal) activated or you can go hollywood style. (big red button smashing)

Oh, No nitros. It´s very difficult to find Nitros Oxide in Bottles for cars, they are very expensive, and here doesn´t have much mechanicals that can make this job...
I prefer to spend more gas in this case

[marcostognozzi]

...by the way, you mean that M5 spends lots of Gas even if you ride it under 3250 RPM as an everyday car?
