Supercharger or turbocharger?

[Saggis]

Hehe...it feels like im just bombarding with questions but ihope others might have use of the answeres too...

well anyway, i want to do some realtime modification and performance enhancments so i was thinking of a turbo or a supercharger for my E34 520.

is there any ptherway to get alotof power out of one mod or at least something that doesnt mean changing half the engine...

What is "best" for the engone, a turbo or a supercharger, which does the least "damage".

AND...what gives the most, turbo or supercharger

Would also be very happy about tips on what items to buy, URL's and/or brands

Thank you very much for any information!

i say who cares what does the most damage, get both.


just kidding, i have no clue. i would think a turbo would do less damage, but i am not the best person to ask about that kind of thing. soem 1 should know

supercharger won't hurt your car as much as turbo does but a turbo will usually provide more power if installed and configured correctly...

Most people will say adding turbo boost to bimmer engines isn't good...

A turbo will go a lot farther in respect to power, but will be more difficult to install, cost more, and rape your engine more quickly... However, with the amount you'd be putting out after, it's well worth it

do a s/c t/c combo best of both worlds

if you have the m20 engine, a turbo isnt too bad of a thing

Seems like anything that pumps air costs big money........but then you may have plenty !

Both jobs you are looking at are pretty much the same.Fitting a turbo-charger is going to be easier to do,but the blower is going to give more power and be easier on the engine.Although most of the late model turbos are intercooled,the air from a blower will be cooler,and thus generate more power.
The difficult part is getting the correct software installed in the cars computer to make it run rite.
Lots of mucking around these type of jobs,and they are never just quite as easy as the instructions promise,and usually wind up costing more and more.
For me if you want more reliable power aim for something with a bigger engine.
All the best for your project.

WOW thank you very much for all the replies!
well im aiming for a new car in two years...hopefully an M5...and that car is gonna get modded big time and get some really juicy ice in it...but i want to dosomething with my tiny 2L until then

so basicly if i combine all these posts i get that the Supercharger will killmy engine less and give me more power than the turbo and willa lso be easier to install...did i get it right?

one more question which i forgot...is it possible to install this by yourself or do you need drilling in the block or something very advanced`?

Also...what exactly is the difference between them...as ive understood the turbo gives of a turbo boost of a lot of extra power at about 4krpm and then reloads and gives another boost at a specifik rpm...and the turbocharger gives extra boost constantly?

Turbochargers take time to spool up (build up boost).... which is why they usually start giving massive power anywhere from 3500-4000 rpm up.

On the other hand, a supercharger is matched to the crankshaft by a belt which gives you power instantly... as you hit the gas pedal and the rpms move up the supercharger is moving as well and pumping air into the engine.

I think the best combo would be a supercharger with a chip and exhaust.

[Saggis]

Okey sounds good...then i think ive got a hold of how things work...now to the practical...what brands are there and is there any made for the E34?

[Torque]

I know of www.turbochargingdynamics.com and www.aatuning.com , but they are both based in the United States... I don't know of any tuners/brands you could find in Sweden.

Try searching for BMW Sweden or something.

just don't drill a hole in your gas tank

Both throw air into your engine, the chief diffrence being that a turbo works off your engine exhaust, while a supercharger is belt driven

I'm not sure if they make one for your engine, but check dinan...you'll get a cool trunk badge too.

actually a SC will do more damage to your engine than a TC.. SC also requires a higher compression ratio to run while a TC needs a lower one.. i would deffinetly go with a turb on that car.. plus nuthin like hearin the impeller spool up and then puff out..
