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
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
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.

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..
CBA>>>>>>>theres nothing like the sound of supercharged engine ! Drive a Dinan supercharged 540 and tell me a turbo sounds better !!
What type of damage do you think these devices will cause the engines...I'd love to know.The only thing I know of is when an engine detonates because of to higher compression with the wrong fuel,however most blokes in the game get around it by running an overlap camshaft which gets rid some of the static compression before the exhaust valve fully closes.
Both turbos and superchargers will give grief if the software is not correct.I agree with you that the turbo is probably a safer bet,but compression is only one part of the equation.For me I think a normally aspirated engine is the best which is really a trademark of the cars we drive.........not many came out from the factory with turbos ahy. The other german brands have done their share of blowing,but consider the M5 V10 and its opposition.....which one would you choose ??
Have a good day.
If i had the new M5 ide sell my house and live in it...true...
but...now ive only got a 520 with max 160hp and that feels kinda light...so i want to do something about it and i cant think about anything but a supoercharger or turbocharger that will do me any good...and now(again) i dont know which one to choose
one argument for engine longevity I've read stated that high RPM is tough on motors. This is the basis for their argument of using a supercharger over a turbo. I know in my car, peak torque is around 4000 rpm. A little boost (5-6lbs) from a supercharger would help a lot!

Okey..Thanks alot guys and/or girls...i think im gonna get a supercharger if anything...now i just gotta find one that fits...both car and economy
is it possible to install by yourself or not?
Yes you could probably fit it yourself but it is fidley stuff with belt tensioners etc.
You are going to need help however with re-programming of your cars software otherwise it won't properly for you,or wont run at all.
Sometimes the sellers of these have the new chip or software included in the package,but they are always set on the conservative side (safe) so it wont kill your engine.
Keep us informed on what type of kit you go with.
Chers.
SILVERLEA.
Hum well...ive checked ebay for some stuff and found some really cheap halfsuperchargers which are powerboosters for airintake...they only press more air intop the car...do they do any good?
i think i will go with the supercharger...but ill put it in my next car...hopefully an m5...feels like money better spent

First off I think a turbocharger would be better than a supercharger, because it's easier to istall (you deal with the exhaust manifold and piping) rather than a supercharger where you have to reconfigure the pullies and removing the intake manifold. Plus superchargers require horsepower to be used to spin it (your using up horsepower to make it) while a tubo is free horsepower, your just using your exhaust gases to spin it, not your crank.
oh and if you need to ask if its easy to install, you'd better leave it to someone experienced, if your gonna spend the money for it in the first place you should get it done right.
Ok first of all let get this strait the amount of time it takes for a turbo to spool to max boost set is figured on several things.
1: the size of turbo being used
2: the the amount of predetemined boost( waste gate and boost controler)
3: the engine size
4: cam
depending on the size of turbo you choose to run and the rest of these factors a turbo can start spooling at 900rpms and max out at 5-6psi at around 2500-3000rpms and hold to redlinenow if you choose to go with a larger turbo like a T-61 or higher then you will run in to the turbo lag until it gets to around 2500-3500 but most people get around this by using a n2o kit with a preset psi sensor to cut it when boost reaches the set build up psi to help spool the turbo quicker but the come in 2 settings that i have seen 7psi and 10psi so the would not be needed for your set up you are looking at of only 5-6psi. So for what you are looking at i would say for fast spooling as far as turbos go you would be looking at a T3 turbo or if you want an even faster spooling turbo a GT28 turbo with ceramic bearings would work better.
As far as which is going to do more damage a turbo or a S/C well they will both do about the same. And no a S/C does not require a higher compression. a higher compression with any forced induction set up = a better chance of pre detonation.But none of that really matters when you only plan to run 5-6psi.Compression ratios only become a factore when you start geting above 7-8psi
and then if you are smart and dont want to melt a piston or bend a rod you would have upgraded to forged piston and h beam rods.
Either way you will have to upgrade your fuel system and have your timing retarded to combat predetonation.personaly i like turbos for the fact if any thing goes wrong with it its a hell of a lot cheaper to buy a new turbo than a new s/c.And anymore a turbo system for the most is cheaper to build a system with than a s/c.
But thats just my opinion so best thing is can say is just do the research and talk to some companys including some local performance shops and see what the have to say. I personaly have several turbo vehicles and am in the process of turboing my 528 so i would love to see some more forced inction BMW's out there . Good luck and best of wishes.
I've got a e34 520i which I've supercharged. I used a kit from European Supercharging Systems in Norway. It a pretty good kit, but has no intercooler. It costs around £3000. I've upped the boost with an 8psi pulley, I'm only getting 6 psi out it, and the car is currently putting out 196.3 BHP.
I'm about to fit an intercooler from a TDS and also add an extra injector as it's running a bit lean. It's then going to travel 500 miles to scotland to have a Dastek unichip fitted to tune it, run the extra injector and up the rev limit. ESS couldn't provide a chip as my ECU is made by Siemens and not Bosch, unfortunately Dastek's UK head office are the only people who can tune it.
I'm hoping with the intercooler and upped revs I should see 8psi and an estimated 227BHP.
Both Superchargers and Turbos have their own advantages and disadvantages, but the supercharger provides a drivability very similar to a standard car but with more power.
I think alot of people can be quite full of it when it comes to the "it'll kill you car" crap. Mines got 145,000 miles on it and it's running fine.

Okey that is v very true...but the thing is i dont just want to send stuff in and get better stuff back...i love getting my hands dirty and trying things out, maybe something will brake maybe it wont even work but in the end when i get it to work i will feel happier than an M5 owner!!
