| Subject: | Static RPM for 100HP EA81 Subaru |
Would someone with a 100HP EA81 Subaru conversion with a three blade
Warp Drive prop tell me what static RPM they're getting and what
pitch setting. I think I've been running mine too coarse and I'm
going to try a finer pitch and would like some ballpark figures to
compare my results to.
Thanks,

Bryan,
With current jetting, my EA81 goes to 5100 rpm static and I fly with the
same prop set to 17-degrees.
Pleased with this setting but that might change if I ever get a LRI
installed.

Warp Drive prop tell me what static RPM they're getting and what
pitch setting. I think I've been running mine too coarse and I'm

Here's what I get on my plane (engine rpm (prop rpm));
warp 3-blade, 70", square tip
stratus 2.2:1 reduction, 100 HP at 5400 rpm
pitch static climb WOT
level
12 deg 4800 (2182) 5000 (2272) 5400+ (2454)
14 deg 4600 (2091) 4800 (2182) 5000 (2272)
16 deg 4200 (1909) 4600 (2091)

Are you measuring the pitch right at the tip or at some other point
on the blade? My Warp drive documentation says to measure at the tip
of the prop. With my prop set at 17 degrees I only get about 4500
static.
