Guzzi question re E10

Yes, that is my experience also.

You're floundering. Suzuki say 'Don't use E10'. Simple as. Kawasaki
ditto. Go right ahead and use it, slowpoke. Good luck.

 

Ethanol increases the RON, so if it ends up at 94[1], it must have
started out life as really crappy fuel. No wonder you're ending up
with 10% less kilometerage.

[1] My R1200GS recommends against using such, but I'm having a hard
time working out whether I can use it at all - the anti knock O2
sensor is documented as being only an (free) "optional extra".

 

and that 95 E10 probably 'is' a cost efective alternative if you can run
it;
typically 1-2c/L more than discount E10 & 1-2c/L less than 91 ULP, but 10
or so c/L LESS than 95 ULP.

It works well for 2 of the 3 cars here and *probably* the Pegaso. I'll
know for sure when I finally get enough time to fix the stupid fuel leak
and get the carbs balanced properly. Postie bikes can't use E10 though.

For personal choice, so do I.
It's just a pity the closest supplier is about 80Km away....

 

Water injection was used a lot on turbo and supercharged engines. I
used to run it in an aftermarket turbo in a MkII Escrot in the late
70s. There was a supply bottle that was fed by manifold pressure
forcing a fine spray of water into the system, but it was downside of
the carburettor. But the better option was to run methanol instead of
water as methanol would cool the charge to stop detonation but would
burn as well once the plugs fired. When I was racing sports sedans
(with the same engine relocated into another car), most of the turbos
had water injection, but methanol was banned as it was seen to get a
performance advantage (well duh). I recall a mate had his water tank
printed with METHANOL across it. I think the scrutineers knew he was
taking the piss.

And I am fairly sure the Rolls Royce Merlin was water injected, but I
have done a bit of a google search and can't find any reference to it.
But something about that stuck in my mind from 30 years ago when we
were injecting the Pinto engine.

 

Dunno... but I found a nice cutaway on the Supercharger installation
though.

" Suzuki Australia does not recommend its use " = " Suzuki Australia
recommends you don't use it ". The phrasing they used eliminates the
pronoun and was therefore probably written by a lawyer. I appreciate
that it is not as emphatic as DON'T EVER USE ETHANOL BLENDED FUELS, as
Kawasaki said, but then they do have to save face and acknowledge that
some Suzuki Owner's Manuals say you can.

Obviously I don't think you're making it up. Nevertheless there are at
least 2 reasons why you should ignore your Owner's Manual and follow the
advice from Suzuki Australia instead: 1) The advice from Suzuki
Australia is almost certainly newer 2) Following the advice from Suzuki
Australia is less likely to do harm to your precious motorcycle, in the
event that one or other of the Suzuki advices is wrong.

You seem to be following precisely this strategy yourself. I originally
said: "All of the Japanese manufacturers say their bikes can't run on
E10." I don't care what your various Owner's Manuals say; all 4 Japanese
manufacturers in Australia have come out and said, via press release and
web site: " We recommend you don't use ethanol blended fuels in our
motorcycles. "

I admit that my first phrasing was not as accurate as it could have been.

 

no - I'm talking about water injection rather than liquid cooled. I
couldn't see anything in that link that referred to water injection.

But it just might be bad memory. But it still sticks in my mind that
the Merlin engine was water injected. I am ready to be corrected on
that one though.

Ta mate.

 

Ahh right, didn't see this before I posted the other reply. Still
doesn't answer whether the Merlin had water injection though.

 

Interesting. Wonder why they didn't use methanol. But as I said, the
use of water in forced induction engines has obvious benefits. As long
as it is downstream of the induction system. I thought the Merlin was
a constrant stream water flow though. A burst system like you describe
sounds a bit weird as it is going to change all sorts of engine
characteristiics. You either have it or you don't. I guess it is
possible to use it to over-rev the engine briefly, but I'd want
something that could power burn as well otherwise you would have to be
changing mixture settings rapidly in said aircraft and in a combat
situation I cannot see the advantage.

 

The Merlins I have seen running generally didn't run H2O injection but
being in boats there was no need , however there was one boat in Nz
running all the aircraft gear called Red Roaster (belonged to the
palmers) and if had the factory kit including water meth spray to lower
knocking when the blower was wound up at high revs
It set a number of water speed records so I assume the spray worked well

 

I can't see how water injection would double horsepower. It would
allow you to run it hotter than normal but even with methanol in it,
the best you'd get would be a 10% increase at my guess. But yes, even
that may save your arse.

But if you have an engine that is running that close to detonation,
I'd be watering it all the time. Mind you, a 27 litre engine is gunna
use a lot of water which is a weight issue in an aircraft I suppose.

 

Well if you need methanol or water injection you are running close to
detonation. That's the whole idea of it. The difference between a
Guzzi and a Spitfire is that fuel ratios change with altitude. Not
many Guzzis do 500 knots at 30,000 ft. Well not any I am aware of
anyway.

 

They probably don't all arrive out here on board a ship.

I heard a rumour that hills motorcycles at castle hill is having a
guzzi/aprillia test day 29th ? august

 

Yeah, Bikebiz today in Parramatta, and next Sun in Castle Hill. I was
thinking of going along myself since I'll be in Sinneytown again next
week.

Exactly right!

My previous test ride of a V7 was also from Castle Hill, but it was a
very new demo bike, and seriously underwhelming.

I'm hoping that the demo machine might have a few more kilometers under
its belt, and be maybe a bit better fettled.

We should be there a bit before noon, when we have booked the ride.
