ok so whats better a turbo or supercharger for performance ,fuel friendliness and sound ???? :)
-
Ive been debating this myself,im currently collecting bits to charge or turbo a vr6 engine,ive got the pistons and rods and a head to get polished and ported.
Im definatley going to either turbo it or supercharge it.
At 1st i was going for a turbo as im clued up on them,but since ive had a guy round picking some bits up he mentioned supercharging it.
He made it sound viable but im not as clued up on them and worry about reliability with the charger itself.
I couldnt give 2 monkeys about economy mind as you dont build a quick car for mpg.
It would be interesting to see what other peoples thoughts are.
-
Superchargers for me. Just plainly because its belt driver and smaller pulleys make it spin faster. Easy to work with. Don't get me wrong turbos are sh!thot but abit more needed. Either way a standalone management to run fuelling. Out of intrest what engine did you want to turbo or charge.
Sorry if this doesn't make sens just woke up.

Superchargers.
-
Id prefer a supercharger, Turbos if small run out of puff too early and just feels like a strong surge mid range. Gay.
-
mmm think you already know my view on this one Adam. :grin:
The thing you really have to think about is that supercharges need recons (standard) every 30k but if they have had smaller pullys and chip then you will be looking at recon every 15-20k, costs vary too and can be very expensive to have them done. Turbo's will last longer is the engine is well looked after.
Like i said to you before adam, i have had a few cars with turbo's and they are amazing but this is my first car with a supercharger and love the sound of this so i am going to sit on the fence on this one and watch what the experts say :grin:
Having said that my bro use to have a mx5 which he supercharged and that was stupidly quick and with the roof down you couldnt hear yourself think but that sound was out of this world. :grin:
-
so much to read so early ah :shocked:
supercharges do sound good
and i was thinking a 2.0 turbo but a supercharger is sounding good imo
you should get a vid up of your car kai so we can hear it. well i want to hear it :grin:
-
friend has a mk2 vr6 z-engineering charger.
it has no headunit and doesnt need one.
:smiley:
-
how hard is it to put a vr6 in a mk2 ??
-
as far as i know. with superchargers you get instant power, with turbo you will have to wait until it has spooled up and then the boost comes along. correct me if im wrong
:cool:
-
Well i will try and update my build thread soon and get a vid on there, but this is what a very nice supercharger sounds like (obviously not running standard but that noise, cant help but smile all day long :grin:)
http://www.youtube.com/watch?v=qyzmrU2bhXk
-
AH sounds good
-
That noise would annoy me lol. He was just cruising?
-
That noise would annoy me lol. He was just cruising?
Thats because it has been heavy modded, they dont all sound quiet as loud, but just wanted to get the idea across as to what a supercharger sounds like.
I dont think i would ever dislike the noise as even just watching the vid puts a smile on my face. :grin:
Think the other thing you need to look into now Adam is how much it is going to cost roughly to achive this???
-
Superchargers are from the start, run out of puff top end, turbo's usually kick in around 2.5/3K on petrol cars.
They are kinda irritating if you put your foot down then suddently they come alive but saying that, once you get the hang of keeping it in the power band, I reckon turbo's are better.
They are more economic on the motorway off boost. But they DRINK fuel.
VR6's are midrange power aren't they?
I'd supercharge it myself but I'd ALWAYS be wondering what the turbo would have been like.
-
BOTH :grin:
Yeah i know it would require and complicated management system. But you would be putting down some serious power.
-
Peak torque on a vr6 is actually over 4000rpm.
-
Peak torque on a vr6 is actually over 4000rpm.
Hmm.
So I guess a turbo could increase that from around that point whereas a supercharger could benefit mostly under and until that?
-
On a vrt the power is basically everywhere.. regardless of what a graph tells you and where its peak is, its fecking too much anyway!
-
Supercharger ftw.
No lag and the whine is awesome.
-
Im swaying towards the supercharging idea.Is there any problem with reconditioning them myself?Can you buy the rebuild kits?Im a mechanical engineer and strip stuff like that all the time but i dont know if they have to be balanced?
Do you need standalone management or can you have a vr6 one remapped?

Standalone is better, also you need to drop compression.
-
well my mate tells me that to get a 2.0 turbo droped in would be 2k from voodoo motorsport
duno how much a 2.0 with a supercharger would be

I know what you mean as i have been looking into recon mine myself, as a mechanic myself it would be a lot cheaper but im not sure where to look into buying a recon kit from or how much they would cost?
I personaly would have a stand alone management as this is easier to set up and easier to play with if there is any problems?

What car is the 2ltr turbo engine coming from. I personaly would look at a VR6 engine and take it from there, the vr engine is awsome engine and well built too and the sound too is fantastic, combine that with a turbo or supercharger it will be like you died and gone to heaven :grin: :grin:
Check the vids below
http://www.youtube.com/watch?v=tosuaqsnoYc
(ignore the end of this vid as its sh*t but the rest is awsome and gives you an insight as to what the vr6 engine turbo will sound like)
http://www.youtube.com/watch?v=QSxeoSnKeoM
This one is one of my all time favs, sounds awsome and the passanger is sooooo funny :laugh: :laugh:
-
Only problem kai is there a bit of a heavy engine but a vrt is a power house
-

That is true but then again the mk2 doesnt weigh that much anyway, like you said the vrt is a power house and i would hope that this would make up for the weight of the engine :grin:
That is what we should do to yours Liam, i know of a guy selling his vr for spares??? Go on you know it makes sence Rodders :laugh:
-
No kai. But martin wants to vr his. How much the person want for engine and such. Got some updates on neg. Eg NO RUST
-
I will check Neg thread now. Not sure how much he wants for it. The only prob is that it has been sat for a year now so it would have to be a case of going down and really seeing what the engine is like.
Anyway like i said im on the fence on this one, supercharger or turbo :undecided: :undecided: If they where women i would marry both and be a bigamist :laugh: :laugh: and have the best of both worlds.
-
Not updated yet gettin the pics tomorow. But well I'll have a word he won't mind building it up but can u see how much he wants for it all
-

Standalone is better, also you need to drop compression.
Ive already got the pistons and h section rods as i didnt want to use one of them pikey spacers :grin:
Will look into sam then.
Hmmm supercharging sounds like fun,the turbo looks like it is a bit of a pig to place and it seems like it will be right up on the bulkhead too.
Im guessing i will have to Quaife the box too?

Nothing wrong with a spacer plate, much better bet than stacking gaskets.
-
spacer plate and stacked gaskets are much of a muchness, both methods loose mean loosing the squish zone round the outside of the piston
-
Well i managed to get some Wossner pistons and H section rods off ebay for a good price a couple of months ago so thought i may aswell do the job properly,as whatever engine i get will be stripped and overhauled anyway.Also when using a spacerplate is there much fannying about with getting the exhaust to fit as the head will be a bit higher?

Not much to be honest as it is not much higher.
-
Spose id best get on VR6OC and see if there are any chargers for sale then. :nerd:
-
Having said that my bro use to have a mx5 which he supercharged and that was stupidly quick and with the roof down you couldnt hear yourself think but that sound was out of this world. :grin:
Lol the 1st thought that came into my head was mx5/gay+supercharger/Manly= Sexually confused man!!!
This is a joke by the way and i'll admit i nearly bought an mx5 due to the great handling and rwd but the hairdresser
jokes put me off!!!

Yeah i know what you mean but they do look like hairdressers cars but handle very well as they are based on the old lotus elan which was awsome handling, my mum still has a mk1 mx5 and bought it new back in 1997 and will never sell it, i have driven it and must say it makes me smile around corners but on a stright i wish i had more power,
Anyway we are getting off the topic, turbo or supercharger????? Getting a little bored now sat on this fence. From what i can gather from this thread they both offer very similiar results and it is all dependent on what noise you like :laugh:
-
Personally i'd go for the turbo, you can get more power than a supercharger and i like the feeling of the turbo kicking in!!
-
That is true but then again a turbo does have lag and starts to puf out at high revs, whilst a supercharger has power stright away and keeps going? I suppose it is really down to what turbo you are running but personally i prefer the sound of a supercharger :grin:
-
R Tech remapped my car and it doesn't run out of puff all the way to the limiter but yeah it does have lag below 2.2k revs,
Who drives below 2.2 revs anyway lol!!! I do like the sound of a supercharger though, it seems a bit more exclusive too!!!
-
Well you defo have had a good remap if it doesnt run out of puff and keeps boosting to the rev limiter, :smiley: That is true though that you never really rolling aroung less then 2k anyway unless you are at some lights and then by law you have to stop :laugh: :laugh:
-
Yeah i had map on by someone else before and the R-tech one knocks the socks off it!! As for the stopping situation
R Tech do a launch control add on which you can see in action on you tube!!! :laugh: :laugh: :laugh:

Turbo FTMFW!
Nothing beats turbo boost! I would love to build my VR with a turbo, but after making some calls and pricing up the turbo, pistons, etc, its too much money. Was looking at a GT28 or GT30 with a custom tubular manifold/downpipe and some serious boosting's.
To build a VRT the way I want it, would costs ££££'s so I'm saving that for after uni :D

Wow that is some crazy build and what an awsome mk1, :cool: :cool:
-
wow that mk1 is teh sex!!! :laugh: :laugh:
-
TURBO ALL THE WAY :evil:
-
superturbo!!
supercharger for while the turbo is spooling up then turbo kicks in. would be running some serious power !

That is true and the new VW TSI engine is fantastic, i use to work for seat and drove the Bocanegra which had a 1.4TSI engine and for something so small to be producing 178bhp was awsome, plus with the added bonus of having the dsg gearbox i had a smile everytime i got in it :grin:
I wonder how hard it would be drop one of those engines into a mk1 or mk2??? The other problem is how much bhp could such a small engine handle????
-
Mate of mine has a 1.4 TSI rocco that's sitting at 200bhp at the moment. No issues at all. In terms of a conversion it wouldn't be far off a 2.0 TSI conversion due to all the wiring and accommodating the taller engine, at which point why not go for the 2.0?
-
what bhp is the 2.0 standard????
-
Less than the R which is the only thing worth having. New cars weigh to much kai. You should no that old school Is the way forward. U in the g-g-g-golf tomorow mate?
-

210 I think.

The R has a 2.0 as well :rolleyes:

if you want ultimate power with NO lag at all, you need to build a nasty littel fuel munching creature called a boost engine. there are diffrent ways of building them it can be done with 2 turbochargers but getting the right inpellers is a b!tch.
basicly you build a jet engine that's sole pourpose in life is to blow as hard as it can into a very large turbocharger. the jet can be fasioned out of a larger turbocharger, if the turbo thats blowing boost in the engines direction has some boost fed into the jet that feeding it's exhaust stage this it to prevent the turbo stalling and it how the boost to the engine is regulated.
the optinal way to do it is to basicly build a turbofan jet engine but the fan in a compressor inpeller desinged for pressure more than flow, this way is much much much mre efficent a lot quiter but still dose get quite hot it is also much more reliable
the advantage of this system is you can have 40+ psi of boost from idel to the red line if you want with NO lag at all, it's actualy more responsive than a supercharger as the whole system is fully pressuriesd all the way to the throttel butterfly all the time. you tune like you would a supercharger enigne but there is no parastic load on the cranck from the supercharger as it's produceing it's own power :laugh:
the downsides are. they are LOUD, they get very very HOT and f**king hell they guzzel some fuel a bit quick
-
I know the 2litres was meaning standard bhp

Sounds like you'd ideally want two, front and rear then you can sit on the fuel tank in the middle...
-
they are actualy quite small espectaly the turbofan type.
smallest self contained unit i've see was 320 mm long ( from air intake to exhaust ) and 175 mm diamiter.
only connections were +12v (start power ) 0v (ground) + 12v (start signal) + 0-12v ( throttel ) fuel feed and return , oil feed and return.
you only want 1 you chould use 1 of them to feed two engines tho chould have one of them frount and one rear
-
*what danny p said*
I just did a little sex wee
-
not much been mentioned on the servicing of a supercharger, every 15k init? i likez my turbos. supercharger whine yes is great but from a practical sense as in an everyday driver id go turbo myself.
-
I thought it was 20-25k for standard chargers? Modded ones go down to 15k??? but i maybe wrong?
-
I thought it was 20-25k for standard chargers? Modded ones go down to 15k??? but i maybe wrong?
only G60's.
Lysholms and eatons are pretty much maintenance (and oil) free. They dont however offer the cool power delivery of the G60, or the noise.
-
Anything with SUPER in the title has to be good.
had a G60 loved the power delivery, turbos are over rated :laugh:

Tell me about it my golf sounds like an monster :grin:, yet got standard gti back box, sounds even better now i have a front mounted intercooler.
-
You need the "chilli pack" from G-Werks if they still do it.
Well or a BBM http://www.youtube.com/watch?v=bAOOv606Zvo
-
eatons are low matance as well, they like the odd oil change but if used out of spec ( rpm and boost wacked up ) they do chew the shock absorber coupeling out that transmits drive from the nose shaft to the primary rotor. uprated poly ones are avalible tho
-
Are the supercharger's serviceable by myself?Are the kits readily available?Im a mechy engineer so do this sort of job all the time,I dont fancy paying someone to do a job I can do myself.Im just not sure if they need balancing everytime you split them?
-
Yes they are mate, Jabba sport will sell you a recon kit for them but i cant remember how much they said it would cost but know where near as much as having it done by them. I am thinking about trying to find someone who knows how to do them and see if they will teach me. :grin:
-
If your any good with the spanners i cant see it being a problem mate,if you take something to bits then at least you know how it goes back together.
I get faced with some horribley complex machines/pumps/motors etc and it's just a case of getting stuck in.
As long you have a bit of nouse then theres nothing to worry about.
Ive started to sway to the idea of a supercharger now,even though i was hell bent on turbo'ing it as i know turbo's inside out.
Time for a new challenge me thinks.
Only problem is id keep wanting to stick a smaller pulley on it. :evil:
-
Thats just it isnt it lol, you make the pully smaller and smaller until your convinced somthing is about to go wrong.... then it does
-
Well i have been thinking of putting a smaller pully and chip on mine but want t get the charger reconed first. I am a training tech for cars so pritty handy when it comes to a spanner and not really phased by doing it myself just would like to see it done first before i do it on my own car.
If you do go ahead and supercharge yours let me know and i will come over and help if you dont mind?
-
Yeah no problem,might as fcuk mine up before we have a go at yours eh!ha ha
But yeah i dont see it being a problem,im currently looking for one now.Ive got all the wossner pistons and rods etc looking foward to building the engine from scratch.
Did I mention i havnt got an engine yet? :grin:
Guess that the easy part :laugh:
-
Dont suppose i can bolt one of these on could I? :evil:

BTW, there is a lot of sh!te being bandied around in this thread by people who think they know something and appear to know nothing.
To the OP, buy a book on forced induction, you will find that there are several different styles of superchargers each with their own benefits (and that doesnt necessarily include lag free performance!) and that are suited to particular types of power delivery with widely varying efficiencies. You will also find that a well sized turbo installation is just as good as any of them if you control it properly, dont chase a ridiculous amount of power or torque, select a modern unit (they have come a long way, especially the VNT ones suited to petrol powered use such as in the Cayenne Turbo!) and take the necessary steps to prevent detonation to allow the use of decent compression ratios.

Sounds good to me. Yeah the engine is the easy part, shouldnt really take long to strip down either. That charger is awsome and bloody cheap, was expecting it be really expansive as seen some G60 chargers which have been reconed going for nearly £700 :shocked:
Maybe me being a geek here but remember seeing this when i was at college a few months back and found it intresting to read, it totally explains how a supercharger works and the different ones out there. Espically like the animations :grin:

Nice little link that!Wil be having a read at work on the toilet tomorrow.I like geeky stuff like that :laugh:
Just out of interest where in Lincs are you?

Had a supercharger on my Jag. Thirsty, even at low revs. The nice little turbo on real Mk5 GTI's is superb. No lag, fast and frugal.

with a correctly sized ball bearing varivle vane turbo you can get some very inpressive powercurves and littel lag. but a boost engine just takes it to a completely diffrent level and willl make you say OhMyf**kingGod as they are absolutly engine smashingly brutal

That I can easily beleive lol!

That however tells you absolutely nothing of any real use about the job of adding a supercharger to your engine. Follow some of the links to the manufacturers pages that appear on there though (or look for them online) and you will find actual geeky stuff. Assuming you have a small budget you will be looking at either a G60 or a mini supercharger. If the G60, just use a G60 engine complete from a corrado as that will be infinately easier and the chargers themselves are much more efficient than the roots style charger they use in mini's. Despite their poor reliability reputation, they are one of the best designs ever produced, they just arent really designed with 100,000 miles worth of use in mind. However, if you use one from a mini, go to the Eaton webpage and have a read on there about them, they even used to have a sizing program on there for their chargers that let you get a vague idea of what gains you could expect from fitting their designs. You would want the larger unit that was fitted to the JCW models I think. The other alternative on a budget comes from I think the Mercedes 230 Kompressor engine (double check that, it might be a slightly larger engine) that uses a whipple/lysholm type that is again, much more efficient than the mini style ones and will allow you to keep some capacity in reserve for later improvements (increased compression ratio, water or methanol spray and proper intercooling along with a properly specced cam and head job).
Oh and to the OP, for fuel economy I would go for a turbo installation using a modern unit and a proper ECU assuming you can keep your foot away from the loud pedal occasionaly or alternatively a supercharger if you fit an electromagnetic clutch to the supercharger drive pulley and a bypass valve for when you arent using much throttle, again using a proper ECU.

You would want the larger unit that was fitted to the JCW models I think. The other alternative on a budget comes from I think the Mercedes 230 Kompressor engine (double check that, it might be a slightly larger engine) that uses a whipple/lysholm type that is again.
Mini and Mercs both use Eaton Blowers, M45 on the Mini and a M62 on the 230k

but a boost engine just takes it to a completely diffrent level and willl make you say OhMyf**kingGod as they are absolutly engine smashingly brutal
That I can easily beleive lol!

That however tells you absolutely nothing of any real use about the job of adding a supercharger to your engine. Follow some of the links to the manufacturers pages that appear on there though (or look for them online) and you will find actual geeky stuff. Assuming you have a small budget you will be looking at either a G60 or a mini supercharger. If the G60, just use a G60 engine complete from a corrado as that will be infinately easier and the chargers themselves are much more efficient than the roots style charger they use in mini's. Despite their poor reliability reputation, they are one of the best designs ever produced, they just arent really designed with 100,000 miles worth of use in mind. However, if you use one from a mini, go to the Eaton webpage and have a read on there about them, they even used to have a sizing program on there for their chargers that let you get a vague idea of what gains you could expect from fitting their designs.

The other alternative on a budget comes from I think the Mercedes 230 Kompressor engine (double check that, it might be a slightly larger engine) that uses a whipple/lysholm type that is again, much more efficient than the mini style ones and will allow you to keep some capacity in reserve for later improvements (increased compression ratio, water or methanol spray and proper intercooling along with a properly specced cam and head job).
Oh and to the OP, for fuel economy I would go for a turbo installation using a modern unit and a proper ECU assuming you can keep your foot away from the loud pedal occasionaly or alternatively a supercharger if you fit an electromagnetic clutch to the supercharger drive pulley and a bypass valve for when you arent using much throttle, again using a proper ECU.
Like Mad Max :cool: I've always thought that would be cool in a black more door mk2 :smiley:

Thought that was probably the case hence the double check it caveat, I knew the "smaller" mercs used Eatons. Its the AMG 3.2 version I meant then. On second thoughts, thats way too big lol, thought it was for a 2.8L engine for some obscure reason.

Yep sounds about right, from memory the M45 is for up to 1.6 and the M62 is for up to 2.5 I believe.
