Spinner question??

Just curious.....on average, how much speed loss would you suffer on a 150 hp RV 3 if you were to use a skullcap spinner vs a standard type of spinner?
Only looking for ?ballpark? numbers......thx in advance for all comments .
 
I ran my RV8 with no spinner for a couple of weeks awaiting repair of the spinner and noticed no difference in cruise speed or CHTs.

YMMV
 
Probably no speed difference, but I would expect a cooling difference, as the round opening normally behind the spinner would pressurize the lower cowl.
