how many turbos are out there

[scumdog]

Got a "resting" '83 Suzuki XN85, was running when I bought it but waste-gate was stuck open

[dangerous]

Ohhhh crap..... now that I read my last post it dosent seem right, bugger it I'd beter go and find a book read up and come back when I'm not sounding like a dumb shit

[DEATH_INC.]

If that's the case you can use any turbo,there's no gas to worry about at the turbo.you'll prolly have to f**k about making flanges ect,but then you'll be able to use a much more modern unit.The primary off a twin turbo legacy is a nice little unit.And don't worry about the water jacket,they work fine dry.

Mate in Hawkes Bay has a Buell somethnig with a Turbo on it. It looks the part, goes better than standard but leaks oil from everywhere. All done in the back shed.
Still cant keep up with his missus on her ZX7R

Speedpro remember you still owe me & Viv a ride on your Turbo

good god those things are over stressed as it is... were did he put it?

Hey the Buell is great, has been converted to chain as it kept breaking drive belts. The front engine mount has only broken twice with the engine hitting the deck once & the rivets holding the front disc have all been replaced as they work their way loose & some electrical gremlins which have seen new battery be installed.
We're just waiting to see which bit will break next, good entertainment.

Turbo is up high on the left hand side, has exhaust plumbing everywhere.
Will try & get some photo's to post or get kiwizrx to.

What actually needs to be done to put a turbo on a basic carburated bike?

Is it as simple as mounting it and doing all the plumbing or is it more involved than that. I think I recall reading somewhere that on most modern engines you have to lower the compression ratio?

From a turbo noob who has never owned a turbo and knows virtually nothing about them except they spin real fast and make you go faster.

Anyone have any informative how to links?

There is/was a V-Max running a Super Charger down south here, does that count? From what can gather it ws a charger off a small Jap car mounted between the V with the intakes poking up thru the imatation fuel tank. Always thought what an eay way to get the black jersey sucked off you if you leaned over the * tank*. Two methds of riding this thing hard appeared to be let it wheel spin like hell or carry the front wheel for ages, take your pick. The other slight problem was the belt drive was with in an inch of your knee and only had a light guard between it and your knee.

how many of you lot in nz own a turbo bike and what sort i have a gpz750 turbo and a second one in pices just looking at another in western aussie

hey dude ..kk and I share the GPZ turbo cause he was only 16 when he wanted to buy it off a mate of mine (he had all the jap turbos in his shed as well as the suzi XN rotor)...KK can run it now hes got better on the track... soon as we do repaint..... cause I still got the ol Z1R turbo waiting in pieces for a rebuild...thats my REAL TOY......

we got KOMPRESSOR on my mister 2 an KK wants to put that on his drag bike but I wanna run it on a V MAX if anyones got a spare MAX mota..

Dollars, low compression forged pistons, dollars, decent con rods, strengthened crankshaft and dollars. Then you have to buy the turbo, a carburretor, probably an oil cooler and...
I remember seeing a turbocharged CBX at Manfeild a few years back. Looked truly awesome (and that wasn't a regular word back then)

You can just fit one up but the boost pressure would have to be set quite low which wouldent give the full benifit but will still make a difference.

The correct mods to do would be as per my CX was altered by Honda
lower compression
smaler valves
semi forged con rods & pistons
much stronger clutch
oil cooler
valcro hand grips and seat

and for your last question this is the only one I can find in my favorites and I cant remember how involved it is http://www.turbomotorcycles.org/

ps: as for carbs, they realy need to be a special kind un less the turbo sucks the fuel mix through the unit..... so I'd hiff em and put injection on

[speedpro]

big valves are good, same flow but at lower boost and temperature, which means you can run a little bit more boost and make more power. It works the same as a normally aspiratd motor. Good head work is advantageous as well for the same reasons - flow, boost, temperature.

Yeah I did wounder that, so I dont know why Honda went for the smaller maybe something to do with strenthening them up. Honda did go over board a bit with the 500tc as the 650tc was scaled down a little eg: 4 less sences and removing the response chamber etc.

I did a turbo Mini engine some years back for a speedway car. Wasn't hard, reasonable cost and very effective (about 130hp at the wheels on a rolling road dyno)
Standard 1300 block, standard crank offset ground to take S rods (smaller journal), Datsun 1200 pistons. This gave a static CR of approx 8:1 which was ok to start with. S valves, 649 cam. 45 DCOE with DellOrto plastic float, IHI RHB6P11 turbo on a fabricated manifold, the turbo was located over the transfer housing (very convenient place to drain the oil to). Turbo blew into an alloy box on the front of the carb, also pressurised the float chamber (hence the plastic floats - weber ones were sheet brass and they collapsed under pressure) Dual sealed bearing each side of the butterfly spindle. Triumph 2.5PI fuel pump, home made regulator valve that had static fuel pressure at about 4 - 5 PSI but increased as boost pressure came on.
Max boost pressure was about 10 PSI and water injection was tried which turned on at about 6 -7 PSI.

This engine was extemely reliable and competed in a class of up to 2.3 litres. It won enough championships that eventually turbos were banned in this class. The car owner spent a fortune trying to make a naturally aspirated engine develop similar power.

I still have an IHI turbo at home. Putting it on the GS1100 is on the list of things I'd like to do (but probably never will)
