Depends on the displacement. The question is: for how long? As Bill says;
"VW's in the larger sizes are hand grenades". HP by it self is meaningless.
Why does a 300 HP over the road truck engine weigh 1500 pounds while a
300 HP car engine weigh 500 pounds?

Subtle differences in the size of the crankshaft, rods, pistons and valves
make all the differences not to mention displacement along with materials, 
manufacturing methods and heat treatment. HP numbers alone in the context 
of differing engine uses is meaningless.

That is why we like the wankel rotary. Lots of HP for a long time
without a lot of weight. The rotary is simple, light weight,
very durable and long lasting. These factors OUTWEIGH ALL OTHER
CONSIDERATIONS for aircraft use.

In ten years everybody will be flying, or wish they were flying,
rotary engines in their light aircraft.
