| Subject: | Re: HS-6 engine needed |
All I can say is that, to the best of my knowledge, all that the Russians did to
go from the AI 14 RA (the first series built-in large quantities, with 260 hp)
to the AI 14 RF of 300 hp was increasing the rpm.
I would be reasonably confident that the same could be done with the HS-6 engine,
particularly because there are also, significantly more powerful versions of
the same engine which would suggest that the basic engine is reasonably strong.
But you should also consider that higher speeds might cause aerodynamic inefficiencies
in the propeller I simply don't know the gearing on the Chinese engine.

Subject: Yak-List: Re: HS-6 engine needed
Thanks Richard.
On that note, would turning up an A be feasible?
Im currently discussing retuning our current engine as it runs very cool. Its very
rare to see more than 170C CHT so Im assuming its stock tune for 70+ octane
where we obviously run 100LL; so advancing by the timing seems the way to go.
Can I safely turn up the max revs in your opinion? 2550 on 6A should easily yield
a good 300hp but at what cost?

HS6 & 6A is 0.787 versus 0.658 for the M14P - presumably as a result of the greater
engine RPM.

So the propeller speed at 2550 rpm with the HS-6 would be equivalent to just
over 3000 rpm with the M 14. Apart from any other issues, I don't think
there would be any consideration of propeller inefficiency at those speeds.

So on that basis, provided the MP limits are respected, is it feasible to increase
METO and max continuous RPMs to the appropriate percentage of the new maximum?

To a certain extent yes, and on one hand these are robust engines with conservative
rpm limits. On the other hand these limits are established for a purpose,
and clearly exceeding them is likely to affect engine life. But we are producing
engines that are fundamentally the same as the original AI 14, but producing
445/450 hp, although with stronger connecting rods; larger bushings and so
forth.

I suppose thats the gamble. Its presumably a reasonable assumption that if the
RF was capable of 300hp, the 6A can also handle it - especially given the auto
plug mod probably moves it close to this value anyway. As it would not be getting
anywhere near M14 values, it certainly seems worth further investigation.

John Warwick's cylinder base nut torque adapter:
For those who don't have one, they might want to consider ordering one.
This adapter fits the fasteners perfectly and is beautifully made. It is
far superior to the original tool that might still be in the tool kit. At
the very least, it looks great in one's tool box!

| Subject: | Re: HS-6 engine needed |
Gentlemen,,, it will become a huge problem as time goes on if there are no overhauls,
or replacement engines for the HS 6A engine,, even motor replacement parts,,
I experienced this a couple years back, I had one being overhauled in China,
until they parked it half way completed, to busy for there own needs.
If the only options are M14,, there are many countries that this motor would not
be approved,, even finding used engines sitting around becomes pretty expensive
investing in labour etc, to get a few more hours in.
To which may be difficult to sell with engines,,,,
David
