I'm looking for a powerplant in the 130-140 hp range. Most
of the rotary conversions I've read about are higher power than
that.
Hi
George,
You see a lot of people
shooting for the 200 HP mark on typical 13B engines, and if everything is right,
they make it. I'd guess that lots of engines start out at more like 150
HP, and only go up as the builder figures out how to fix his original mistakes
:-)
For example, it's easy
to install a short, straight intake. You can buy it off the shelf, it's
light, it fits in the cowl, BUT it won't make the magic 200 HP, so along
comes the long curved tubing and shoe horn to make it all fit. If you read
the archives, you will note that most people make multiple intakes before they
get it "right".
In your case, you can
save lots of headaches by not worrying about the extra power that's in
there. If you're really happy with 140-150 HP, then you can take the easy
road when it comes to packaging your intake and exhaust. This power
level is just loafing for the rotary, so reliability should be a
given. Lower power means smaller radiators, oil coolers, etc, so the
weight can be reduced as well.
So, it's plenty doable,
but it's still a lot of work, and something you have to really want to
do.
Cheers,
Rusty
