OK ...I'll jump in ...
Flying solo with full tanks I'm consistently seeing +1600FPM at 90-95kts at 50 to 70F OAT.
... A fellow 9A driver with an IO-360 tells me +2000 FPM is no problem.

Sorry, I'm asking for vertical, as in how many feet you can climb straight up before you stop. I understand people's numbers will vary just post what you have experienced. Entry speed alt etc

vertical versus airspeed
Erik,
I determined the vertical height in a hammer head versus entrance airspeed awhile back, but can't find the data. Aircraft is an RV-4, 160 hp, fixed Performance prop, max rpm 2750 WOT, entrance altitude 2000 feet AGL, 4 G pull to vertical. Airspeeds varied from 110 to 160 knots. The max vertical at the top of the hammer head was about 1100 feet at 160 knots rotation speed. I also saw 7000 ft/min on the VS with the Dynon.
Cheers,
Bill McLean
