Hey i was just thinking, since the supercharger runs on a belt and a turbo uses the exuast (that spins it anyways), would it be possible to modify a turbo and make it run of a belt ?

I have no intention of doing anything like this the idea just popped into my head.

I think this would be sweet :D

as far as i know, NO you couldnt do this...

charger runs off a belt, not sure what happens inside, then power...

turbo works off of exhaust gasses & then spins the turbine and compresses the gasses, forces them back into the cylinder, then power...

so im not sure what the belt would to to a turbo dude.. what do you mean?

I mean insted of geting the exuast fumes to spin the turbo, get the belt to do it. (bolt it up like an alternator :D )

You could modify just about anything to do just about any other thing if you have enough time and money.. but the real question is, why? :P

it would use HEAPS more fuel i would think? :eh:

Why not ?

It would be cool to buy a cheapy turbo, modify it and bolt it onto a junk car and just kill it :D

cant argue with that logic...

buy a RB25 R31 Skyline and kill that... ITS FUN :D

Well that concept your proposing is what we call, a supercharger :D

Well that concept your proposing is what we call, a supercharger :D

The cheapest supercharger you could find (if you go for second hand stuf)

I think by the time you modify a turbocharger into a supercharger and be mechanically sound (if that is at all possible) it would cost way more then the cheapest supercharger you can get on the market.

u can get s/c already like this

I was thinking more about this and i dont think the engine would be able to spin up a turbo as fast as the exuast would (i think)

This is why superchargers are expensive because they have gears in them to make it spin fast ?

If it can spin it fast enough, whats stopping someone from ripping of the blade and welding on a pully from a broken alternator ?

I know to do it all properly it would cost way to much i just thought it would be something cool to try if you had a couple hundred bucks lying around.

Just buy a supercharger already made.
But by all means I see what you mean & you could most probably do it however it would cost you more.

Just a quick note, it is not the Exhaust gases that get compressed it is the air (from air filter) that gets sucked into the compresser that gets compressed.

All the exhaust does is spin the turbine then exits the turbo.

Just one problem: the turbo spins at rather high rpm (as i understand), so you would need a fair bit of gearing up to convert it to a supercharger. A better option, is to search ebay and get an old supercharger from there. They guy I bought my parabolics off is selling a supercharger that came off a Toyota 2L. Im sure with a little bit of modification it could be made to fit our things. If I had a spare 3 grand lying around I would of bought it by now...

cheers for that dude.. i knew the exhaust played some part lol


the turbo spins at rather high rpm

i got told its something MASSIVE

like, cars revving at 600rpm... turbo's going at 150,000rpm...

is that ^^ an exageration?

Yeah I've thought about it myself, but if you look at the design of a turbo compressor wheel to a supercharger compressor wheel they're a very different design. The supercharger wheel is like a huge paddle, fairly shallow in cross section but with a huge diameter(centrifugal this is) this layout leans towards low driving speeds for large flow levels, but on the flip side fairly inefficient and fairly low boost.
A turbo wheel on the other hand has quite a deep cross section and usually less than half the diameter therefore requiring much higher driving speeds, providing more efficiency and the opportunity for much more maximum boost, on average turbo compressor wheels operate at over 120,000 rpm, and things like rally cars with size limited turbos/intakes can operate at over 200,000rpm.
So basically to drive the turbo comp wheel hard enough your gearing would be ridiculous and the pulleys wouldn't last 2 weeks not to mention the bearings inside the supercharger would be doing much much more work than with a standard design centrifugal wheel.

I'm sure people have tried and to some extent succeded with this experiment but for the sort of engineering required it'd be a much better bet just to use a centrifugal blower.

All the exhaust does is spin the turbine then exits the turbo.

Mostly right, except the exhaust gasses actually spin nothing, the energy from the heat of combustion tries to expand to cool down, ordinarily this equals flow out of the exhaust, but in a turbo instead of being let out easy the exhaust is forced into an ever tightening scroll(turbine housing) and the only way out is through the turbine wheel which is shaped to deliver drive from this highly energised(hot) air trying to expand, thus the turbine drives the compressor end.
Some big turbos on diesels have had their drive output measured at 35hp, this means that basically the turbine wheel is providing 35hp to the comp wheel just from spent exhaust gas, so if you look at it thats about 9 briggs and stratton lawn mowers driving the compressor wheel :badgrin:

Matthius

Thanks for the explanation Matthius. I knew there was a reason that i havent seen anyone do this.

O well it was a good idea at the time lol

Or you could run a turbo or two into a supercharger! Im sure most people have seen it before on the orange torana that won SMOTY 2004 i think. Steve something madeit cant remember his last name.......But this would be something cool you could do?

i Have no idea how this idea works im guessing turbos feed compressed air into the supercharger which then compresses it again?.

correct me if im wrong.

Also guys a supercharger is positve displacment(i.e it has s seals of sorts) where a turbo charger is not. Nice idea though. :D

Yeah something like that, not sure of the exact rpm but it is insane.

R31's only came in RB20DET. you're thinking of an R32 GTR or R33.

They come in rb30's too (aus spec ones)

Its been around for a while. There was a red Corolla a few years back (4PERVN I think) that got onto the cover of Hot4s that employed this theory and Nissan even released a car from the factory! This Nissan March SuperTurbo. The equivilant of our Nissan Micra, but a few years earlier. It was small, only about 800cc but ran a tiny supercharger so that it was on boost from the get go whilst the turbo finally spooled up! It was released for rally homolgation so that it could run in the factory class! One LS1 tuning shop has developed a kit with a roots type supercharger and a centrifical bower!

but they werent DET were they? im sure they werent DOHC....

I think they were just RB30E

I think.

but they werent DET were they? im sure they werent DOHC....

your right R31's didn't come with the RB30DET

oh and R32 GTR's were 2.6ltrs not 2.5 :)

Speaking of factory SC/TC setups in the early eighties Lancia had a rally car, the delta s4 which also had a homologation version, it was a 1.8l producing in excess of 550 hp :) this just gives you an idea of the potential of this sort of setup :P

I think the VL Turbo come out with that one.

u dont need to convert it. u go on this site www.capa.com.au and u'll see a s/c that looks like a turbo :cool:

Wholly **** them things are not cheap!!

Would love something like that for my magna but im dreaming :cry:

thats without a rebuild

Damn.

im jealous because we had to follow my mate in his r33 gts-t and wholly crap it was impossible to keep up even though he wasnt pushing it at all.

I have driven an r33 gts-t before but trying to keep up to one is different.

i kept up with neosabers r33

Was in my brothers VN.

I was tripping out on how fast this thing is. I knew the VN wouldnt of stood any chance but DAMN!!

This is my mates skyline

http://www.imports101.com.au/ride_pics/fullsize/52-3.JPG

It has been tuned and has parts by some guys called Impul in Japan.

I think the VL Turbo come out with that one.

yup, VLT's came out with RB30ET, so SOHC not double.

and yes BLKMAG my mistake, all GTR's (cept the new one!!) are RB26DETT. R32's are RB20DET

umm sorry i didnt read the whole thread.. but a turbo that runs off a belt is basically exactly what a pump style supercharger is already isnit??

Oh and this reminds me, cant find a picture of it but some nutter in queensland built a car that was both a supercharged AND TWIN turbocharged V8... omg it was a dead set peice of art!! everything was chrome and it was just a dead sexy peice of machinery.. pure porn! My gf got annoyed cos i spent 10 minutes just stairing at it at the recent AME show

yeah ive noticed a negative reaction from g/f's when you pay more attention to a car/ races than you do to them...

i dont understand it?!?!? cars ARE interesting lol

I take it your talking about your ex's?
I love going to car shows, Hence why I went to the horse power show(and the drifts/drags they did) last year,
and small car sunday..
and going to AutoSalon this year, etc ;)

I love watching Rally driving on tv, and the V8 super cars, but I cant stand watching racing when its cars im not interested in, or if there is a better tv show on :)

sif watching the racing porches isnt ineresting lol

and the turbo cars & poniacs on teh track....
\/roooooooooooooooooooooooooom

i posted the car before but ill show you again
if you want it as your wallpaper, go to www.streetmachine.com.au and go to the downloads section and get it there, makes a really nice background i tells ya that!

so while your car is in perth getting the rpw TT kit, send it to sprintex as well. some1 has to be crazt enough to do that-i suggest AWD :bowrofl:

I have an idea............Is it not possible to have a supercharger feeding a turbocharger since they both work differently around the motor? I can't think of anything that would come in the way except room and stress on the motor.

hmmmm maybe the other way around since the supercharger is at constant boost and you dont want to destroy the turbo but i dont know.

you can if you wanna destroy your turbos.. you have to have the turbo's feeding the supercharger, not the other way around or otherwise you will do serious damange

Supercharger provides instant power unitl the turbo's have built up boost..
Upside of running a Supercharger
1.Instant Power available from idle, can get great results with as little as 4psi.
2 If the Charger Breaks no worries the car will just run as normal as there is nothing impeding exhaust flow..

Down side
1. Very expensiveto get running.
2. not many front wheel drive engine will except one with out the engine bay getting cluttered
3. Belts have to be replaced often to avoid slipping.


Upside of a Turbo
1. Boost being applied to the engine has dramatic effect turns a lame duck into a soaring eagle
2. Can be made to adapt to a Front wheel drive with not much clutter to ad to the engine bay
3. Most of the time is more expensive and is able to have boost Variable from economy to full thrust via after market computer from inside the cabin...
(could be an upside or a downside)

Downside..
1. If it Blows then the most probably will result in new engine internals and that can be very costly
2. Heat is a Major factor and the engine bay will need additional cooling to prevent the engine from overheating
3. Unlike a Supercharger, if a Turbo fails, engine performance can suffer a huge blow due to the engine needing to be de-compressed for High Boost applications and a Dead Turbo impeeds exhaust flow...
4. More pipe work for intercooling and Exhaust manifolds can complicate initial installation

2 If the Charger Breaks no worries the car will just run as normal as there is nothing impeding exhaust flow..



Hehe, if the charger breaks usually your engine will **** itself :) the impeller enters the engine and proceeds to get munched by the pistons which will either fail or be damaged enough to shorten their life considerably same as a turbo, also if the supercharger runs on engine oil(rather than it's own reserve) then your engine will bleed itself to death like a lamb with it's throat cut ;)

Matthius

you can if you wanna destroy your turbos.. you have to have the turbo's feeding the supercharger, not the other way around or otherwise you will do serious damange

Haha...I guess thats what I was trying to say. And I thought turbo setup would run cooler then a supercharger.

umm sorry i didnt read the whole thread.. but a turbo that runs off a belt is basically exactly what a pump style supercharger is already isnit??

I will say it again a supercharger is positive displacment a turbo is not e.g a supercharger has internal seals where as a turbo does not. :shock:

Why not ?

It would be cool to buy a cheapy turbo, modify it and bolt it onto a junk car and just kill it :D
how cheap a turbo are you going to buy? why not just buy a toyota 6cyl supercharger (sc12 or sc14) and bolt it up and kill it.. blower will cost you $350 from www.justjap.com.au (in adelaide)


so why screw around with converting a turbo?

I wont be trying to do this now because i now know that it wont work out.

BTW, would that blower be good for a V6 Commie ? All this talk about superchargers and turbo's has got me thinking about getting one for my brothers commie (or my 1st gen :badgrin: )

I would like to be able to piss over my mates skylines in my brothers commie because they always bag aussie cars (even my magna :rant: )

Im having trouble navigating through that justjap site. Could you link me up to the sc14 plz ?
