Hi All, thanks for the responses, was not meant to be a trick question but
definately a newbie question. I was curious after reading about people
using
mazda 13b engines for various homebuilts, and porting them, adding on
various components to boost the hp from 200 to 260+. Seems at a point that
it's overkill if the 200 hp engine is going to provide you with the
needed
ponies and rpms to accomplish the same as the 260 hp engine. What would
the
advantge be of having the extra horsepower ?

Thanks,

Mark

Does a prop turning at 2300 rpm on a 150hp motor produce more thrust
than
a
prop spinning 2300 rpm on a 100 hp motor ?




Mark,

A "typical" 13b (non-turbocharged) for aircraft is closer to 180-200 Hp.
A turbo will get you to that 250 hp mark, if you need it. Without the right
prop, the power is not usable.
