more horsepower

hello there....I was interested in putting floats on my Cessna 172
O-300 and need some more Horsies........not drag........any ideas
less putting a bigger engine in it....

With the floats, you can go to a bigger prop, with a flatter
pitch to allow higher RPM at take-off speeds, but top speed
will be reduced slightly because you won't be able to have
as high a manifold pressure without over-revving the engine.
If your O-300 has a constant speed prop option (hollow crank
or perhaps an electric prop) you would gain better take-off
power and cruise speed.

The O-300 C172 is pretty old and float operating is a high
stress operation. You might be better off finding a C172
with the factory float mods and structural bracing/upgrades.

How about one of those exhaust pipe systems that give you up to 155 more HP.
I can't think of the name, right now.

Powerflow? I've heard they're good, but I don't think they increase
horsepower *that* much!

That is one brand. I think I am thinking about another brand. Who knows
about how much increase, really. Anyone (most, anyway) promoting an
increased HP product, tend to boast about their effectiveness. g'

Anyone know how much Powerflow does increase HP?

Oh crap! Now I see what Jay was questioning me about! That was supposed to
be 15 [shift] %.

That's funny, 155 more hp on a 172.

That is completely accurate. A 1 HP increase is "up to" 155!
