Paging the Turboisti

Which is why, as I'm sure I've said before, certain railway locos have
electric pumps supplying oil to the multiple turbo units for a period of
time (35 minutes IIRC) after the engines have been shut down.

 

It would be cheaper to start with a nice bike to begin with if you're
after a *very* nice machine. The one I have is very usable, although
just not at the moment.

 

It's in my lockup looking sorry for itself and now I have certain,
non-motorcycle related, things out of the way I will be putting it back
on the road.

I would certainly recommend getting a bike that doesn't have a rag
wrapped round the oil pickup.

I scored a good S/H engine for £150 and the diesel to Dudley and back.

Other parts are readily available but may take a bit of hunting. I got a
set of replacement clocks for £50ish, a good seat for £35, spare turbo
unit for £50.

Very few of the major components are shared with the normally aspirated
GPZ 750 of the era. Brakes and suspension seem to be but I've not put it
to the test yet.

 

^^^^^^

Jihad ahoy!

 

Possibly an unwise assumption with a turbo motorcycle.

 

I'm sure that'll be for cooling rather than because the rotors carry on
spinning for 35 minutes.

But a good turbo diesel is designed for abuse, after all look at the
French drivers' use of them. The turbo XUD whilst a little agricultural
seemed to cope with being caned from cold and not being given specific
spin-down time.

 

It's certainly less likely to **** it in these days of synthetic oils.
In fact turbos were one of the main drivers behind the development of
synthetic oil iirc.

I've always been anal about warming engines up fully anyway, turbo'd or
not. I don't like the idea of things thrashing around at high speed
before they've had a chance to expand to full size. Fnarrrrr.

whaaaat?

Oh, right, the old "only superchargers are allowed to be referred to as
'blowers'" argument, is it?

I don't really care enough to argue about it.

Well done for that other thing, BTW.

 

Actually, I don't. I was just curious as to how easy it'd be to develop
an expensive turbo habit.

Interesting read that was, thanks.

 

"cool down", you ****.

 

Probably but the explanation in the GM books was to provide lubrication
for the turbos. We weren't permitted to cut out the main battery
switches until the 'turbo light' had gone out.

 

I can't see a turbo remaining hot enough to cook oil for 35 minutes....

 

They aren't the same either. The discs are bigger and I *think* the
calipers are bigger too.

Suspension was uprated as well. I daresay a lot of the parts are
interchangeable but yes, you're right - a lot of components look the
same but aren't.

The cylinder head is straight Z650, though.

 

Only because it gives me a frisson of excitement that I may be spoiling
an older man's pleasure.

You're no fun.

It sorely tested my temperance thing.

 

Except for the mechanical tacho drive on the 650s?

 

Or both, ffs.

 

You mean you'd **** him in the ass, but not have the common courtesy to
offer a reach-around?

so I'm told.

I can imagine. So what's the excuse for no beers this evening? Some
tedious train-driving to be done at the weekend or somethign?

 

Me neither, but that's not the only reason for cooling them. 35 minutes
seems extreme whatever the reason though.

I can.

The engine rooms get fucking hot, enough to set fire detectors off; the
engine itself (I'm talking about crankcases not exhaust manifolds here)
would be too hot to touch for ages and the turbo units themselves are the
size of a washing machine drum.

<reaches into dim memory banks> There where four of them on English
Electrics; the GM 59s also had superchargers in addition to the turbos.
