550 turbo?

[arve]

I have become somewhat bored with my gs 550 m.But why?Its trouble-free,and it runs just fine.Its just that now that I have become used to it,I think that it lacks that little extra sting that makes my day.And since I dont **** money,I cant afford a new bike with more power.And also,I'm very satisfied with the bike,its just this powwer issue.So I am playing with the idea of putting a turbo on it!:twisted:Since the compresson is so low(only 8,somthn to 1)it shouldnt be necessary to do anything to the engine itself(my friend put a turbo on his honda civic and it has over 9:1 ratio)if boost is kept on a reasonable level.To keep costs down,I'm getting a turbo from a daihatsu charade turbo.It should be a reasonable fit,as it has an engine below 1000 cc that certainly doesn't rev anwhere near 10k rpm.Got a 4-1 system thats rusted anyway,so I am cutting it straight after the collector,placing the turbo under the bike.But now comes problems.At first,where should the oil pressure come from?I can drill a hole,thread it and put on a banjo coupling,but where?Or perhaps it's wiser to locate the switch for the oil lamp and put a "t" coupling there?And what about the return line,could I just hook it to the drain plug under the bike,or will it need to go up first?Or will it blow the sealings if the used oil isn't helped by gravity all the way?An oil-cooler also sound like a good idea.And then we have the carbs.Is it possible to just pressurize the existing carbs without any major modifications?(which was my thought)Will I need bigger main jets?(the honda civic has stock nozzles,just a turbo bolt on and voila-250+ hp.Yes,that's an injected engine,but there is no air amount meter so it shouldn't make any difference.)Maybe an injection system from a small car can be rebuilt to fit my bike.I have many thoughts,but what do you think,dear readers?Do any of you have any experience or knowledge about this,or even better:has anyone tried this on this bike??I have seen a GSX 1100 with a turbo,but it was somewhat different from my ideas.First of all,the turbo was placed behind the cylinders and there was a special header and intake manifold,as it used only one of the carburetors bolted on the intake of the turbo,drawing mixture through it.If I do it this way,there will be no problems with the oil return line,but in a such case I will need to (have) fabricate(d) new exhaust and intake manifolds,a topic I know nothing about.It will complicate things and increase costs,it will maybe alter driveability with the long intake route and the single carburator,and thus the whole thing should maybe be left undone anyway?No,I want my bike just as before,just with the difference of alittle turbo punch when I open the throttle.Maybe I could use a bigger turbo with a belt pulley instead of exhaust turbine,thereby acting as a centrifugal supercharger?Maybe an electric supercharger?And what about a NOS system,can it be fitted do you think??Please help me,I'm bored here.Just need alittle extra power on that bike,and someone to tell me how to achieve it.Does anyone of YOU know any ways???Please let me know.Sincerely yours,Arve Kvalvik,Norway. :-D

if you do a forum search for turbo there are actually a couple threads that are for larger bikes, but would be helpful i would imagine. at least give you a direction to start it.

WOW, lots of issues and questions, so I am just going to copy your post and answer them as I go:

I have become somewhat bored with my gs 550 m.But why? It's trouble-free,and it runs just fine.Its just that now that I have become used to it,I think that it lacks that little extra sting that makes my day.And since I dont **** money,I cant afford a new bike with more power.
Remember this point for later comment.

And also,I'm very satisfied with the bike,its just this powwer issue.So I am playing with the idea of putting a turbo on it!:twisted:Since the compresson is so low(only 8,somthn to 1)it shouldnt be necessary to do anything to the engine itself(my friend put a turbo on his honda civic and it has over 9:1 ratio)if boost is kept on a reasonable level.
Your compression ratio should not be a problem, but if you are going to "keep boost down to a reasonable level", it will come in rather late in the rpm range and will not really be useable.

To keep costs down,I'm getting a turbo from a daihatsu charade turbo.It should be a reasonable fit,as it has an engine below 1000 cc that certainly doesn't rev anwhere near 10k rpm.
If only it worked that way. Just because you have half the engine size and spin it twice as fast does not necessarily mean that you will have enough exhaust to drive the turbine properly. It would be much better to get a properly-size turbo.

Got a 4-1 system thats rusted anyway,so I am cutting it straight after the collector,placing the turbo under the bike.
Unless you somehow raise the bike, there will not be enough room.

But now comes problems.At first,where should the oil pressure come from? I can drill a hole,thread it and put on a banjo coupling,but where?
There are likely places that can be used to supply oil, but you have to be careful that you are not taking an oil supply away from a critical part. I do not know the oil flow pattern of your bike, so I will not suggest a location.

Or perhaps it's wiser to locate the switch for the oil lamp and put a "t" coupling there?
I would think that the switch depends on a certain amount of resistance in its passage, and tapping into that would affect it rather greatly.

And what about the return line,could I just hook it to the drain plug under the bike,or will it need to go up first?Or will it blow the sealings if the used oil isn't helped by gravity all the way?
Any turbo install that I have seen has oil pressure-fed to the turbo, then a gravity drain back to the crankcase. There could be an exception if you had a scavenging pump to lift the oil back into the crankcase, but fabrication would be a nightmare.

An oil-cooler also sound like a good idea.And then we have the carbs.Is it possible to just pressurize the existing carbs without any major modifications?(which was my thought)
With enough time and money, anything is possible. To pressurize your existing carbs, you will have to build an enclosure that will go completely around the carbs and will be TOTALLY sealed. You might be able to get rid of the airbox and filter (in it's stock location), but will have to add a filter somewhere in the system.

Will I need bigger main jets?(the honda civic has stock nozzles,just a turbo bolt on and voila-250+ hp.Yes,that's an injected engine,but there is no air amount meter so it shouldn't make any difference.)
This is where it gets really interesting. Yes, you will need bigger main jets, as you will (maybe) be flowling a LOT more air. However, most of the time, you will be running off-boost, so you need close to stock jetting in the pilot and needle circuits.

Maybe an injection system from a small car can be rebuilt to fit my bike.
What happened to your original statement that you "don't **** money and can't afford ..."?

I have many thoughts,but what do you think,dear readers?
I think this could be an admirable project, but is obviously beyond your budget.

Do any of you have any experience or knowledge about this,or even better:has anyone tried this on this bike??I have seen a GSX 1100 with a turbo,but it was somewhat different from my ideas.First of all,the turbo was placed behind the cylinders and there was a special header and intake manifold,as it used only one of the carburetors bolted on the intake of the turbo,drawing mixture through it.
It was done that way because it is a tried-and-true method.

If I do it this way,there will be no problems with the oil return line,but in a such case I will need to (have) fabricate(d) new exhaust and intake manifolds,a topic I know nothing about.It will complicate things and increase costs,it will maybe alter driveability with the long intake route and the single carburator,and thus the whole thing should maybe be left undone anyway?
"Long intake"? Have you looked at it? Only a couple of inches longer than stock. Now look at your system with the turbo under the engine and tell me which one has a longer intake. You have to consider more than the distance from the carb(s) to the engine, it is the entire system from the turbo to the engine.

No,I want my bike just as before,just with the difference of alittle turbo punch when I open the throttle.Maybe I could use a bigger turbo with a belt pulley instead of exhaust turbine,thereby acting as a centrifugal supercharger?
Might work, but you then need to rig a pulley, and you still need a sealed airbox.

Maybe an electric supercharger?
Our electric systems barely handle the lights, no way they would handle a motor big enough to drive a supercharger.

And what about a NOS system,can it be fitted do you think??
This might be your best bet, but note that they are usually set up to only work at full throttle.

Please help me,I'm bored here.Just need alittle extra power on that bike,and someone to tell me how to achieve it.Does anyone of YOU know any ways???Please let me know.Sincerely yours,Arve Kvalvik,Norway. :-D
Seriously, for all the time, engineering and that you would have to put into a turbo bike (even a ready-made kit), you will be able to afford TWO larger bikes that make that much power STOCK.

[Steve]

Just so you know, I am not totally ignorant about adding a turbo to a vehicle that was never designed for it. I have not done it to a bike, but I did add one to a Toyota Corolla, back in 1975. Ended up with 22 psi of boost and close to 325 hp out of a 1.6L engine :shock: and overall mpg dropped from 30-32 stock to 24-26. I considered that a fair trade. 8-[

LONG LIVE HORSEPRESSURE!

[WesV]

If you wanna add a little pep to your 550, talk to Nerobro or skreemer, one of them put a 650 head I sold them on his 550 (can't keep those 2 straight, both came to get the head and another bike together).

 

[Dan Ruddock]

I have owned a GS550e and a GS1000e. The GS1000 will cure the boring problem quite nicely. Dan

 

[RJ]

I would agree with WesV about bolting up the 650 top end (head and cyliders) on your bike. You will use readily available parts (at least here in the USA) and you have a thread on this website that walks you through the process step by step. If you really want to go crazy you could stuff a something like a GSXR 750 engine in there. That would be a really fast bike, although that brings you back to a lot of engineering issues and increased costs.

I have an 80 gs550e, and it has a lot of spunk. But then again, I have nothing to compare it to. It is the highest cc bike I have ever owned. I can't imagine what a 1000 would be like.:shock:

Perrkele man,jag forst?r inte finska,but the pictures were interesting.Saw the kit for the gsxr 750,with special manifold so the turbo is just in front of the engine.Saw also similar setup on a Bandit,but there is no box around the carbs here like Steve meant was needed,do you know if they use special carbs?There were no carbs included in the gsxr kit.Perhaps I could use carbs(that can withstand pressure in original form)from another bike if they fit in the rubber intakes on my bike?

Helvete ! H?r ?r en annan adress :http://forum.oldskoolsuzuki.info/cgi-bin/Yabb/YaBB.pl?board=forcedinduction
There you can find all information you need to know about turbo or supercharging .
Most of the original carbs can be pressurize (if they have a metal "hats"). Carb boxing belongs to a pre historic turbo age .
With right tuned and built turbo system you can "easy" get out 100 hp from your 550 bike .

Thanks,you have been very helpful.If it can be done in Finland it can probably be done here too.And the best part is it wont cost significantly more than an old turbo from the scrapyard.I have the plan clear now..First make a manifold like Arttu had done on his gsx,and a box for replacing the stock air filter.There are CV carburators on my bike and they can be pressurized,just have to connect the overflow tubes to the air box as well,and they don't need rejetting!Yes,thats what the dude said and he had tried it on his bike.If you think about it,it doesnt sound unreasonable as the fuel chamber is pressurised as well as the air intake,so it will theoretically still retain the correct mixture.Maybe it will even run richer when the flow rate is much bigger than it ever was intended for.An then I need a fuel pump with bigger pressure than max boost,from some old fuel injected car,or else the charge will end up in the fuel tank.Then some plumbing,and that's pretty much it!Just need to figure out where to take oilpressure from.But enough talk,I'm off to the scrapyard now.See you when the bike is ready.Arve.

 

[ArttuH]

That's right attitude! Good luck for the project. And remember to report about the result.

 

[skivit]

at www.oldskoolsuzuki.info there is a couple of turbo bikes, larger displacements (gsx1000 or gsx1100), with all the problems/solutions these guys had in their own projects. Might be worth a look for inspiration or just for fun.
good luck,
skivit

 

[robinjo]

Get an oilcooled GSXR 750 engine and bolt that in, a good one has about 120 hp stock, cheapest way of more then doubling your HP IMO.

 

[skivit]

robinjo?

robinjo?

sorry to go off topic here, is that robin from zeist?

This is Robin from Driebergen right next to Zeist.

 

[zig06]

Ok, back on topic.

How about just boring it out? The stock engine is 572cc's, does anyone know of a kit or a different set of pistons that can push the displacement on one of the newer 550's (TSCC's). Maybe even dropping in a stock set of 700es pistons?? :grin:
